How to make REST API calls from atvise

atvise has a function called "HTTPClient" which you can find in the HELP menu.  This function is used to call REST methods.

Here are 2 examples

1. Example to make a GET method call using BASIC authentication and parsing a JSON format reply from the REST Server

//Open conection HTTPClient()

var http = new HTTPClient()

//Execute GET command

var res = http.get("http://localhost:3003/tag?cmd=read&path=/*",

{auth: {method: "basic", user: "vnode", password: "vnode"}

});

//PARSING

var cadena_patron="\"data\":{\"value\":";

var indice=(res.data).search(cadena_patron);

var indice2=((res.data).slice(indice)).search(",");

var data_limpia=(res.data).slice(indice+cadena_patron.length,indice+indice2);

console.log(data_limpia);

//Return clean value

return(data_limpia);

2. Example to make a POST method using BASIC authentication.

//Open conection HTTPClient()

var http = new HTTPClient()

//POST Command execute

var res = http.request({

    protocol: "http",

    hostname: "localhost",

    port: 3003,

    path: "/tag?cmd=write",

    method: "POST",

    data: JSON.stringify({"path": "/prueba", "value": writevalue}),

    auth: {method: "basic", user: "vnode", password: "vnode"}

});
