Google Cloud Functions 启用 CORS? [英] Google Cloud Functions enable CORS?

问题描述

我刚刚完成了 Hello World Google Cloud Functions 教程并收到了以下响应标头:

I just finished the Hello World Google Cloud Functions tutorial and received the following response headers:

Connection → keep-alive
Content-Length → 14
Content-Type → text/plain; charset=utf-8
Date → Mon, 29 Feb 2016 07:02:37 GMT
Execution-Id → XbT-WC9lXKL-0
Server → nginx

如何添加 CORS 标头以便能够从我的网站调用我的函数?

How can I add the CORS headers to be able to call my function from my website?

推荐答案

我们开始:

exports.helloWorld = function helloWorld(req, res) {  
  res.set('Access-Control-Allow-Origin', "*")
  res.set('Access-Control-Allow-Methods', 'GET, POST');

  if (req.method === "OPTIONS") {
    // stop preflight requests here
    res.status(204).send('');
    return;
  }

  // handle full requests
  res.status(200).send('weeee!);
};

然后你就可以像往常一样使用 jquery/whatever 了:

then you can jquery/whatever it as usual:

$.get(myUrl, (r) => console.log(r))
