使用Facebook图表API在Facebook上通过网址发布视频 [英] Post a video by URL on facebook using the facebook graph API?

问题描述

我有一个Facebook页面，我正在尝试上传一个已经托管在我的服务器上的视频。
我需要通过javascript这样做，我所有的都是src链接（类似于 https://cdn.whodaman.net/Q45rt7y.mp4 ）的视频。作为管理员，我拥有所有必需的权限（ publish_stream，manage_pages ）。

I have a facebook page, and I am trying to upload a video to it that is already hosted on my servers. I need to do this via javascript, and all I have is the src link (something like https://cdn.whodaman.net/Q45rt7y.mp4) of the video. Being the administrator, I have all required permissions (publish_stream, manage_pages).

facebook api 说，我必须发送数据为 multipart / form-数据这意味着视频内容。所以要通过ajax这样做，我遵循这个问题在stackoverflow上，并遵循如何在jQuery中使用Ajax请求发送FormData对象。

The facebook api says that I have to send the data as multipart/form-data which means the video content. So to do this via ajax, I followed this question on stackoverflow, and followed How to send FormData objects with Ajax-requests in jQuery.

这是我的 JavaScript代码：

var fd = new FormData();
fd.append( 'source', 'https://cdn.whodaman.net/Q45rt7y.mp4' );
fd.append( 'access_token', testaccessToken);
fd.append( 'title', "Test Video");
$.ajax({
  url: "https://graph-video.facebook.com/"+testPageId+"/videos",
  data: fd,
  processData: false,
  contentType: false,
  type: 'POST',
  beforeSend: function(xhr) { 
    xhr.setRequestHeader('Content-Type', 'multipart/form-data'); 
  }
});

以下是请求和相应的回复：

Facebook正在要求访问令牌！我确定我有一个正确的，因为我可以添加一个文本状态的帖子。我还尝试将表单数据中的文件的名称从 source 更改为文件不起作用。

Facebook is asking for the access token! I'm pretty sure I have the right one, because I'm being able to add a text status post. I have also tried to change the name of the file parameter in form data from source to file to no effect.

甚至可以通过js sdk直接从视频网址上​​传视频到Facebook？我有一种感觉，而且非常接近解决方案。

So is it even possible to upload a video to facebook via the js sdk directly from the video url? I have a feeling it is, and am quite close to the solution.

推荐答案

对图表执行POST请求api使用file_url字段指定您的视频的网址，并摆脱源字段，不需要多部分/表单数据。

Perform a POST request to the graph api Using the file_url field to specify the url for your video and get rid of the source field , no need for a multipart/form-data .
