获取命令行（桌面）应用程序的Facebook身份验证令牌 [英] Obtaining a Facebook auth token for a command-line (desktop) application

问题描述

我正在为促进手语的慈善事业工作，他们每天都要向他们的FB页面发布一个视频。有大量（并且不断增长）的视频，所以他们想以编程方式安排上传。我真的不介意我最终做了什么编程语言，但是我尝试过以下操作，并没有太远：

I am working for a charity which is promoting sign language, and they want to post a video to their FB page every day. There's a large (and growing) number of videos, so they want to schedule the uploads programmatically. I don't really mind what programming language I end up doing this in, but I've tried the following and not got very far:

• Perl使用 WWW :: Facebook :: API （旧REST API）

• Perl using WWW::Facebook::API (old REST API)

my $res = $client->video->upload(
 title => $name,
 description => $description,
 data => scalar(read_file("videos/split/$name.mp4"))
);

身份验证正常，并正确发布了 facebook.video.upload 方法到 https://api-video.facebook.com/restserver.php 。不幸的是，这返回方法未知。我认为这是与不推荐使用的REST API有关。

Authentication is OK, and this correctly posts a facebook.video.upload method to https://api-video.facebook.com/restserver.php. Unfortunately, this returns "Method unknown". I presume this is to do with the REST API being deprecated.

fb_graph gem中的3aGraph> Facebook :: Graph 。 （OAuth API）

Facebook::Graph in Perl or fb_graph gem in Ruby. (OAuth API)

我甚至不能认证。这两个都适用于网络而不是OAuth的桌面应用程序，但我认为我应该能够做到：

I can't even authenticate. Both of these are geared towards web rather than desktop applications of OAuth, but I think I ought to be able to do:

my $fb = Facebook::Graph->new(
 app_id => "xxx",
 secret => "yyy",
 postback => "https://www.facebook.com/connect/login_success.html"
);
print $fb->authorize->extend_permissions(qw(publish_stream read_stream))->uri_as_string;

在我的浏览器中访问该URL，捕获代码参数返回，然后

Go to that URL in my browser, capture the code parameter returned, and then

my $r = $fb->request_access_token($code);

不幸的是：

Could not fetch access token: Bad Request at /Library/Perl/5.16/Facebook/Graph/AccessToken/Response.pm line 26

与Ruby类似，使用 fb_graph ，

fb_auth = FbGraph::Auth.new(APP_ID, APP_SECRET)

client = fb_auth.client
client.redirect_uri = "https://www.facebook.com/connect/login_success.html"
puts client.authorization_uri(
  :scope => [:publish_stream, :read_stream]
)

给我一​​个URL它返回代码，但运行

Gives me a URL which returns a code, but running

client.authorization_code = <code>
FbGraph.debug!
access_token = client.access_token!

返回

{
  "error": {
    "message": "Missing client_id parameter.",
    "type":    "OAuthException",
    "code":    101
  }
}

更新：当我更改 access_token！调用 access_token！（foobar）来强制Rack :: OAuth2 :: Client放置标识符和秘密进入请求正文，我收到以下错误：

Update: When I change the access_token! call to access_token!("foobar") to force Rack::OAuth2::Client to put the identifier and secret into the request body, I get the following error instead:

{
  "error": {
    "message": "The request is invalid because the app is configured as a desktop app",
     "type":   "OAuthException",
     "code":   1
  }
}

使用OAuth验证桌面/命令行应用程序到Facebook？

How am I supposed to authenticate a desktop/command line app to Facebook using OAuth?

推荐答案

所以，我终于得到它的工作，没有设置Web服务器并进行回调。这个伎俩，反直觉地是关闭桌面应用程序设置，而不要求 offline_access 。

So, I finally got it working, without setting up a web server and doing a callback. The trick, counter-intuitively, was to turn off the "Desktop application" setting and not to request offline_access.

FaceBook :: Graph 支持发布视频目前似乎不起作用，所以我最终在Ruby中做到这一点。

FaceBook::Graph's support for posting videos doesn't seem to work at the moment, so I ended up doing it in Ruby.

fb_auth = FbGraph::Auth.new(APP_ID, APP_SECRET)

client = fb_auth.client
client.redirect_uri = "https://www.facebook.com/connect/login_success.html"

if ARGV.length == 0
  puts "Go to this URL"
  puts client.authorization_uri(:scope => [:publish_stream, :read_stream] )
  puts "Then run me again with the code"
  exit
end

if ARGV.length == 1
  client.authorization_code = ARGV[0]
  access_token = client.access_token! :client_auth_body
  File.open("authtoken.txt", "w") { |io| io.write(access_token)  }
  exit
end

file, title, description = ARGV

access_token = File.read("authtoken.txt")
fb_auth.exchange_token! access_token
File.open("authtoken.txt", "w") { |io| io.write(fb_auth.access_token)  }

me = FbGraph::Page.new(PAGE_ID, :access_token => access_token)
me.video!(
    :source => File.new(file),
    :title => title,
    :description => description
)
