POST请求到Picasa API [英] POST request to Picasa API

问题描述

我心中已经是挣扎在Picasa中API POST。
这里是code：

I'v been struggling with POST on the Picasa API. Here's code:

$.ajax({
    type: "POST",               
    url: 'https://picasaweb.google.com/data/feed/api/user/' + uid + '/albumid/' + album_id + '/photoid/' + photo_id,
    crossDomain: true,
    data: { content: content },
    success: function() { alert("Success"); },
    error: function() { alert('Failed!'); }
});

我已经通过检索获得一些信息没有问题。

I've already retrieved some information via GET without problems.

现在到了有趣的部分，当我尝试测试与谷歌服务出现此错误：

Now comes the fun part, when I try to test the service with Google this error occurs:

 XMLHttpRequest cannot load
 https://picasaweb.google.com/data/feed/api/user/userid/albumid/albumid/photoid/photoid?content=foo%bar.
 Origin http://localhost:3000 is not allowed by
 Access-Control-Allow-Origin

当我尝试在Firefox中的请求头的方法更改为选项和地位是 204：无内容 。结果
另外，我试图改变数据类型到 JSONP 但随后的HTTP方法更改 GET 并检索有关图像信息。

And when I try in Firefox the request header method is changed to OPTIONS and status is 204: no content.
Also, I've tried to change datatype to jsonp but then HTTP method changes to GET and it retrieves information about the picture.

推荐答案

访问控制允许来源来了，因为你正在一个Ajax调用到服务器，是不是与您当前的域。

Access-Control-Allow-Origin is coming because your are making a ajax call to a server which is not same as your current domain. Read more here

JSONP 将不利于为 POST 请求，因为你只能让 GET 与要求 JSONP 。

jsonp will not help for POST request because you can only make GET request with jsonp.

恕我直言，你应该尽量让从服务器端，而不是客户端脚本的POST请求。

IMHO you should try to make the POST request from server side instead of client side script.
