The possibility of including the "post" method in the webapi plugin

[JefersonBigheti]

First of all congratulations for the excellent project. I would like to know if there is a possibility to include the "post" method in the webapi plugin.

Hi, thank you for your appreciation.
we have the feature planned but our resources are currently limited.

there is a functionality to configure via a environment variable DEVICES the webapi get to read tag properties and post to write values

The post method or a webhook-like method can make a lot of work easier. I will eagerly await this.

I'm having trouble implementing it. Would you have an example of how to implement post using your suggestion "environment variable DEVICES"

[unocelli]

• your web application (device) have to serve the REST API get and post (exp. GET -> http://localhost:8080/api/tags POST -> http://localhost:8080/api/tags)
• you modify the environment parameter envParams.js configs.getTags and configs.postTags with your GET/POST url.
• you start fuxa server with arguments node main.js --env=test
• in UI you can ask in the connection section the tags configured in your web application through GET (normally will be asked by start)
  

The tags must be in an array (flat structure) as you can see in the following example

var tags = [
    {
        id: 'tempA',     // UUID
        name: 'tempA',
        value: 0,
        type: 'number'  // number|boolean|string,`
    },
    {
        id: 'tempB',    // UUID
        name: 'tempB',
        value: 0,
        type: 'number'  // number|boolean|string,`
    }
]
apiApp.get('/api/tags', function (req, res) {       
    res.json(tags);
});

apiApp.post('/api/tags', function (req, res) {
    if (req.body && Array.isArray(req.body)) {
        for(let i = 0; i < req.body.length; i++) {
            for (let y = 0; y < tags.length; y++) {
                if (req.body[i].id === tags[y].id) {
                    tags[y].value = parseFloat(req.body[i].value);
                    y = tags.length;
                }
            }
        }
    }
    res.end();
});

The example shown worked very well.
Thanks a lot for the help!

Hi actually I have a opcua client running in fuxa. From a standalone opcua server I am able to get the opcua variables in fuxa. Now these opcua variables I want to expose to the application layer (upper layer) so that the application can read write the opcua variables. can you kindly guide me how to do that ?

[unocelli]

@RajatDas2020 Hi, I will use mqtt, install a broker (mosquitto) and export the opcua values

Hi @unocelli I am trying to use this application but seems like the WebAPI properties only works on GET ?

Am I missing something here? or the Post method already removed?
