在使用JavaScript的Azure函数中，如何调用将请求发送到端点 [英] In azure functions using javascript how to call send request to a endpoint

问题描述

在Azure函数中，如何使用 javascript 调用API.该请求是带有标头的POST.我尝试使用 XMLHttpRequest ，但出现了类似XMLHttpRequest的异常.

In Azure function how to call an API using javascript. The request is POST with the header.I tried to use XMLHttpRequest, but i got exception like this XMLHttpRequest is not defined.

var client = new XMLHttpRequest();
    var authentication = 'Bearer ...'
    var url = "http://example.com";
    var data = '{.........}';

    client.open("POST", url, true);
    client.setRequestHeader('Authorization',authentication); 
    client.setRequestHeader('Content-Type', 'application/json');

    client.send(data);

还有其他方法可以实现这一目标，

Any other method is there to achive this,

推荐答案

您可以使用内置的http模块(node.js的标准模块)来做到这一点:

You can do it with a built-in http module (standard one for node.js):

var http = require('http');

module.exports= function (context) {
  context.log('JavaScript HTTP trigger function processed a request.');

  var options = {
      host: 'example.com',
      port: '80',
      path: '/test',
      method: 'POST'
  };

  // Set up the request
  var req = http.request(options, (res) => {
    var body = "";

    res.on("data", (chunk) => {
      body += chunk;
    });

    res.on("end", () => {
      context.res = body;
      context.done();
    });
  }).on("error", (error) => {
    context.log('error');
    context.res = {
      status: 500,
      body: error
    };
    context.done();
  });
  req.end();
};

如果将其安装到Function App中，还可以使用其他任何npm模块，例如request.

You can also use any other npm module like request if you install it into your Function App.
