<h3 id="数组"><a href="#数组" class="headerlink" title="数组"></a>数组</h3><p><code>JavaScript</code>的数组声明不用关注元素类型和数组长度</p>

<p><code>Golang</code>提供了一些方法操作切片</p>
<p><code>len()</code>可以查看切片的长度<br><code>cap()</code>可以查看切片指向的数组的长度</p>

<p>相当于<code>JavaScript</code>中的<code>Array.prototype.length</code>属性</p>

<p>在前端我们主要使用<code>JavaScript</code>作为主要开发语言，我们来逐一对比<code>JavaScript</code>与<code>Golang</code>的语法特性，来帮助前端工程师更快入门<code>Golang</code>。</p>
<h3 id="变量声明"><a href="#变量声明" class="headerlink" title="变量声明"></a>变量声明</h3><p>在<code>JavaScript</code>中，使用<code>var</code>或<code>let</code>关键字来声明变量</p>
<figure class="highlight javascript"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line">{</span><br><span class="line"> <span class="keyword">let</span> a = <span class="number">10</span></span><br><span class="line"> <span class="keyword">var</span> b = <span class="number">1</span></span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>在<code>Golang</code>中，同样使用<code>var</code>关键字声明变量</p>
<figure class="highlight golang"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">var</span> a = <span class="number">10</span></span><br></pre></td></tr></table></figure>
<p>由于<code>Golang</code>是一门强类型的语言，如果省略了类型声明，编译器会做类型推导，上面这种变量声明方式实际上等价于</p>
<figure class="highlight golang"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">var</span> a <span class="keyword">int</span> = <span class="number">10</span></span><br></pre></td></tr></table></figure>
<p>在函数中，使用<code>:=</code>符号可以更简便的声明并初始化变量</p>
<figure class="highlight golang"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line"><span class="function"><span class="keyword">func</span> <span class="title">main</span><span class="params">()</span></span> {</span><br><span class="line"> a := <span class="number">10</span></span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>除了变量，我们还有声明常量的需求，<code>Golang</code>和<code>JavaScript</code>常量的声明方式也是一样的</p>
<figure class="highlight golang"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">const</span> a = <span class="number">10</span></span><br></pre></td></tr></table></figure>
<h3 id="条件语句"><a href="#条件语句" class="headerlink" title="条件语句"></a>条件语句</h3><p><code>JavaScript</code>条件分支语法继承自<code>C</code>语言</p>
<figure class="highlight javascript"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">let</span> a = <span class="number">10</span></span><br><span class="line"><span class="keyword">if</span> (a > <span class="number">0</span>) {</span><br><span class="line"> <span class="built_in">console</span>.log(a)</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p><code>Golang</code>的条件分支不带小括号，支持在条件里写多个表达式，用<code>;</code>号分割，并且在条件里声明的变量只在<code>if</code>条件模块内部有效</p>
<figure class="highlight golang"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">if</span> a := <span class="number">10</span>; a > <span class="number">0</span> {</span><br><span class="line"> fmt.Println(a)</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>条件分支中最容易忽略的是<code>switch</code>结构。</p>
<p>在<code>JavaScript</code>中，每个<code>case</code>要使用<code>break</code>关键字终止流程</p>
<figure class="highlight javascript"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">switch</span> (fruit) {</span><br><span class="line"> <span class="keyword">case</span> <span class="string">"banana"</span>:</span><br><span class="line"> <span class="comment">// ...</span></span><br><span class="line"> <span class="keyword">break</span></span><br><span class="line"> <span class="keyword">case</span> <span class="string">"apple"</span>:</span><br><span class="line"> <span class="comment">// ...</span></span><br><span class="line"> <span class="keyword">break</span></span><br><span class="line"> <span class="attr">default</span>:</span><br><span class="line"> <span class="comment">// ...</span></span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p><code>Golang</code>很人性化，每个<code>case</code>会自动<code>break</code></p>
<figure class="highlight golang"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">switch</span> fruit {</span><br><span class="line"> <span class="keyword">case</span> <span class="string">"banana"</span>:</span><br><span class="line"> <span class="comment">// ...</span></span><br><span class="line"> <span class="keyword">case</span> <span class="string">"apple"</span>:</span><br><span class="line"> <span class="comment">// ...</span></span><br><span class="line"> <span class="keyword">default</span>:</span><br><span class="line"> <span class="comment">// ...</span></span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>如果需要顺序执行代码，还加<code>fallthrough</code>关键字</p>
<h3 id="循环语句"><a href="#循环语句" class="headerlink" title="循环语句"></a>循环语句</h3><p>在<code>JavaScript</code>中，循环语句有<code>while</code>、<code>do while</code>、<code>for</code>、<code>for in</code>、<code>for of</code></p>
<p>在<code>Golang</code>中，没有那么多花里胡哨的东西，只有万能的<code>for</code></p>
<figure class="highlight golang"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">for</span> i := <span class="number">0</span>; i < <span class="number">100</span>; i++ {</span><br><span class="line"> fmt.Println(i)</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p><code>for</code>的起始条件、递增条件、结束条件都是可选的，甚至可以不带任何条件，就表示一个死循环</p>
<figure class="highlight golang"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">for</span> {</span><br><span class="line"> <span class="comment">// ...</span></span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<h3 id="函数"><a href="#函数" class="headerlink" title="函数"></a>函数</h3><p>在<code>JavaScript</code>中，函数用<code>function</code>关键字声明</p>
<p>在<code>Golang</code>中，函数用<code>func</code>关键字声明，并且与<code>JavaScript</code>一样，函数是一等公民，支持闭包</p>
<figure class="highlight golang"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br></pre></td><td class="code"><pre><span class="line"><span class="function"><span class="keyword">func</span> <span class="title">createIncrementor</span><span class="params">(start <span class="keyword">int</span>)</span> <span class="title">func</span><span class="params">()</span> <span class="title">int</span></span> {</span><br><span class="line"> <span class="keyword">return</span> <span class="function"><span class="keyword">func</span> <span class="params">()</span> <span class="title">int</span></span> {</span><br><span class="line"> start++</span><br><span class="line"> <span class="keyword">return</span> start;</span><br><span class="line"> }</span><br><span class="line">}</span><br><span class="line"> </span><br><span class="line"></span><br><span class="line"><span class="function"><span class="keyword">func</span> <span class="title">main</span><span class="params">()</span></span> {</span><br><span class="line"> inc := createIncrementor(<span class="number">5</span>);</span><br><span class="line"> </span><br><span class="line"> inc() <span class="comment">// 5</span></span><br><span class="line"> inc() <span class="comment">// 6</span></span><br><span class="line"> inc() <span class="comment">// 7</span></span><br><span class="line">}</span><br></pre></td></tr></table></figure>

<p>我们会使用<code>npm init</code>初始化一个项目，初始化完成会在当前目录下生成一个<code>package.json</code>的文件, 我们还会安装一些依赖，比如执行<code>npm install axios</code>安装<code>axios</code>http请求库，安装完成查看<code>package.json</code></p>
<figure class="highlight json"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br></pre></td><td class="code"><pre><span class="line">{</span><br><span class="line"> <span class="attr">"name"</span>: <span class="string">"module"</span>,</span><br><span class="line"> <span class="attr">"version"</span>: <span class="string">"1.0.0"</span>,</span><br><span class="line"> <span class="attr">"description"</span>: <span class="string">""</span>,</span><br><span class="line"> <span class="attr">"main"</span>: <span class="string">"index.js"</span>,</span><br><span class="line"> <span class="attr">"scripts"</span>: {</span><br><span class="line"> <span class="attr">"test"</span>: <span class="string">"echo \"Error: no test specified\" && exit 1"</span></span><br><span class="line"> },</span><br><span class="line"> <span class="attr">"keywords"</span>: [],</span><br><span class="line"> <span class="attr">"author"</span>: <span class="string">""</span>,</span><br><span class="line"> <span class="attr">"license"</span>: <span class="string">"ISC"</span>,</span><br><span class="line"> <span class="attr">"dependencies"</span>: {</span><br><span class="line"> <span class="attr">"axios"</span>: <span class="string">"^0.21.1"</span></span><br><span class="line"> }</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p><code>package.json</code>描述了整个项目的大致情况, 包括模块名字、模块版本号、模块描述、入口文件、模块脚本配置，作者、开源协议以及依赖情况。</p>
<p>项目下还存在一个<code>package-lock.json</code>文件, 它记录当前安装的每个依赖包的版本，</p>
<p>在运行<code>npm install</code>的时候，<code>npm</code>会使用这些确切的版本。</p>
<figure class="highlight json"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br></pre></td><td class="code"><pre><span class="line"><span class="string">"dependencies"</span>: {</span><br><span class="line"> <span class="attr">"axios"</span>: {</span><br><span class="line"> <span class="attr">"version"</span>: <span class="string">"0.21.1"</span>,</span><br><span class="line"> <span class="attr">"resolved"</span>: <span class="string">"https://registry.npmjs.org/axios/-/axios-0.21.1.tgz"</span>,</span><br><span class="line"> <span class="attr">"integrity"</span>: <span class="string">"sha512-dKQiRHxGD9PPRIUNIWvZhPTPpl1rf/OxTYKsqKUDjBwYylTvV7SjSHJb9ratfyzM6wCdLCOYLzs73qpg5c4iGA=="</span>,</span><br><span class="line"> <span class="attr">"requires"</span>: {</span><br><span class="line"> <span class="attr">"follow-redirects"</span>: <span class="string">"^1.10.0"</span></span><br><span class="line"> }</span><br><span class="line"> },</span><br><span class="line"> <span class="attr">"follow-redirects"</span>: {</span><br><span class="line"> <span class="attr">"version"</span>: <span class="string">"1.14.1"</span>,</span><br><span class="line"> <span class="attr">"resolved"</span>: <span class="string">"https://registry.npmjs.org/follow-redirects/-/follow-redirects-1.14.1.tgz"</span>,</span><br><span class="line"> <span class="attr">"integrity"</span>: <span class="string">"sha512-HWqDgT7ZEkqRzBvc2s64vSZ/hfOceEol3ac/7tKwzuvEyWx3/4UegXh5oBOIotkGsObyk3xznnSRVADBgWSQVg=="</span></span><br><span class="line"> }</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>可以看到软件包的版本、下载地址、用于校验依赖包的sha512值和它的依赖，这里我们发现<code>axios</code>依赖了<code>follow-redirects</code>。</p>
<p>这些依赖安装到了项目下的<code>node_modules</code>目录。</p>

<h2 id="Golang的依赖管理"><a href="#Golang的依赖管理" class="headerlink" title="Golang的依赖管理"></a>Golang的依赖管理</h2><p>Golang的依赖管理方案经历了一个曲折的过程。</p>
<p>GOPATH: 把所有的项目文件和依赖全部放在一个目录里，不同项目没办法使用不同版本的依赖，所以有了GOVENDOR。</p>
<p>GOVENDOR: 每个项目有自己的vendor目录，项目优先到vendor目录查找依赖，其次到GOPATH目录查找。</p>
<p>目前最新的Golang依赖管理是使用Go Modules。</p>
<p>使用<code>go mod init <module></code>的方式初始化一个go mod项目</p>
<blockquote>
<p><code>go mod init</code>相当于<code>npm init</code></p>
</blockquote>
<p>使用<code>go get <module></code>的方式安装一个依赖包</p>
<blockquote>
<p><code>go get</code>相当于<code>npm install</code></p>
</blockquote>

<p><code>go.sum</code>记录了依赖的版本号，像<code>package-lock.json</code>一样也有依赖的依赖的版本号，还有校验依赖包的sha512值</p>
<blockquote>
<p>h1:开头的字符串，表示生成checksum的算法是第一版的hash算法，即sha256。</p>

<p>下载的依赖不像<code>Node.js</code>项目一样存放到当前<code>node_modules</code>目录，而是存放到<code>GOMODCACHE</code>目录，<code>GOMODCACHE</code>是一个go环境变量，通过<code>go env</code>可以查看<code>GOMODCACHE</code>的位置。</p>
<p><code>cd</code>到<code>GOMODCACHE</code>指向的目录，我们发现它是按照模块名来组织依赖的。</p>

<p>好家伙！它是按版本来存放依赖的，以<code>@</code>符号作为版本分割符，这样就解决了多版本共存的问题。</p>
<h2 id="总结"><a href="#总结" class="headerlink" title="总结"></a>总结</h2><p>本文大致讲述了<code>Node.js</code>项目与<code>Golang</code>项目依赖管理的方式，对比了<code>Node.js</code>和<code>Golang</code>项目依赖管理的相同点和不同点。<code>Node.js</code>项目把依赖存放到项目的<code>node_modules</code>目录；<code>Golang</code>采用在项目下记录依赖，依赖文件实际存放到统一目录，这也是更通用的方式。</p>
<p>看到这里，我相信你对Golang的依赖管理已经有了一个基本的认识。</p>

<h2 id="环境搭建"><a href="#环境搭建" class="headerlink" title="环境搭建"></a>环境搭建</h2><p>我们在前端搭建环境时会先安装<a target="_blank" rel="noopener" href="https://nodejs.org/">Node.js</a>，安装Node.js有几种方法</p>
<ol>
<li>下载安装包或二进制文件</li>
<li>使用系统包管理工具安装</li>
<li>使用版本管理工具安装</li>
</ol>
<p>对应我们也有这几种方法可以安装Golang</p>
<h3 id="下载安装包或二进制文件"><a href="#下载安装包或二进制文件" class="headerlink" title="下载安装包或二进制文件"></a>下载安装包或二进制文件</h3><p>我们可以在<a target="_blank" rel="noopener" href="https://golang.org/dl/">Golang下载页</a>找到不同系统对应的安装包或二进制文件，这里不再赘述。<br>这个方案版本升级不太方便，需要手动下载最新版本覆盖旧版本，这里更推荐下面的方案。</p>
<h3 id="使用系统包管理工具安装"><a href="#使用系统包管理工具安装" class="headerlink" title="使用系统包管理工具安装"></a>使用系统包管理工具安装</h3><p>在不同的系统都有自己的包管理工具，可以让我们很好的对应用进行管理</p>
<p>在Windows下，目前较好用的包管理工具是<a target="_blank" rel="noopener" href="https://chocolatey.org/">Chocolatey</a>，使用Chocolatey安装：</p>
<figure class="highlight powershell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">choco install golang</span><br></pre></td></tr></table></figure>
<p>在Mac下，最好用的包管理工具当然是<a target="_blank" rel="noopener" href="https://brew.sh/">Homebrew</a>，使用Homebrew安装：</p>
<figure class="highlight bash"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">brew install golang</span><br></pre></td></tr></table></figure>
<p>安装命令执行完成后输入命令 <code>go version</code> , 控制台打印golang版本号则代表安装成功。</p>
<h3 id="Golang版本管理工具"><a href="#Golang版本管理工具" class="headerlink" title="Golang版本管理工具"></a>Golang版本管理工具</h3><p>在Node.js中，有<a target="_blank" rel="noopener" href="https://github.com/nvm-sh/nvm">nvm</a>, 对应在Golang社区也有<a target="_blank" rel="noopener" href="https://github.com/moovweb/gvm">gvm</a></p>
<p>可以用 <code>gvm install</code> 命令显示可以下载和编译可用的 Golang 版本</p>
<p>安装特定的 go 版本只需运行 <code>gvm install <version></code>命令，其中 <code><version></code> 是表示要安装的版本。假设你正在处理一个使用 go 1.16.7 版本的项目，你就可以使用 <code>gvm install go1.16.7</code> 命令来安装这个版本。</p>
<p>使用 <code>gvm use </code> 命令来切换到新安装的 go 1.16.7 版本。如果不想每次敲 gvm use 指令来切换版本，你可以加上 –default 参数来指定默认使用这个版本。</p>
<p>这里还要介绍另一款工具是<a target="_blank" rel="noopener" href="https://github.com/voidint/g">g</a>, 它与Node.js的<a target="_blank" rel="noopener" href="https://github.com/tj/n">n</a>也是一样的用法</p>
<p><code>g ls-remote </code> 查询可供安装的所有go版本</p>
<p><code>g install <version></code> 安装目标go版本</p>
<p><code>g ls</code> 查询已安装的go版本</p>
<p><code>g use <version></code> 切换到另一个已安装的go版本</p>
<p><code>g uninstall <version></code> 卸载一个已安装的go版本</p>
<h3 id="国内镜像配置"><a href="#国内镜像配置" class="headerlink" title="国内镜像配置"></a>国内镜像配置</h3><p>在使用npm安装项目依赖的时候，我们会设置npm的源来加快安装速度。</p>
<figure class="highlight bash"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">npm config <span class="built_in">set</span> registry https://registry.npm.taobao.org</span><br></pre></td></tr></table></figure>
<p>同样go的中央仓库也在国外，我们需要设置go的国内镜像，可以使用<code>goproxy.cn</code> 或 <code>goproxy.io</code> </p>
<figure class="highlight bash"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">$ go env -w GO111MODULE=on</span><br><span class="line">$ go env -w GOPROXY=https://goproxy.cn,direct</span><br></pre></td></tr></table></figure>
<h2 id="Hello-World"><a href="#Hello-World" class="headerlink" title="Hello World"></a>Hello World</h2><p>创建一个main.go文件</p>
<figure class="highlight golang"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">package</span> main</span><br><span class="line"></span><br><span class="line"><span class="keyword">import</span> <span class="string">"fmt"</span></span><br><span class="line"></span><br><span class="line"><span class="function"><span class="keyword">func</span> <span class="title">main</span><span class="params">()</span></span> {</span><br><span class="line"> fmt.Println(<span class="string">"hello world!"</span>)</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>控制台运行 <code>go run main.go</code> </p>
<figure class="highlight bash"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">$ go run main.go</span><br><span class="line">hello world!</span><br></pre></td></tr></table></figure>
<p>至此，我们第一个Hello World程序就完成啦！是不是很简单呢？</p>
