我正在为一家推广手语的慈善机构工作,他们想每天在其FB页面上发布视频。视频数量众多(并且还在不断增加),因此他们希望以编程方式安排上传时间。我真的不介意我最终会使用哪种编程语言,但是我已经尝试了以下方法,但并没有走得太远:
WWW::Facebook::API
(旧的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,这可以将
facebook.video.upload
方法正确地发布到https://api-video.facebook.com/restserver.php
。不幸的是,这返回“方法未知”。我认为这与REST API被弃用有关。 Facebook::Graph
或Ruby中的fb_graph
gem。 (OAuth API)我什至无法验证。这两个都是针对OAuth的Web应用程序而非桌面应用程序的,但我认为我应该能够做到:
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;
在我的浏览器中转到该URL,捕获返回的
code
参数,然后my $r = $fb->request_access_token($code);
不幸:
Could not fetch access token: Bad Request at /Library/Perl/5.16/Facebook/Graph/AccessToken/Response.pm line 26
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]
)
给我一个返回代码但正在运行的URL
client.authorization_code = <code>
FbGraph.debug!
access_token = client.access_token!
退货
{
"error": {
"message": "Missing client_id parameter.",
"type": "OAuthException",
"code": 101
}
}
更新:当我将
access_token!
调用更改为access_token!("foobar")
以强制Rack::OAuth2::Client将标识符和 secret 放入请求正文中时,出现以下错误:{
"error": {
"message": "The request is invalid because the app is configured as a desktop app",
"type": "OAuthException",
"code": 1
}
}
我应该如何使用OAuth向Facebook认证桌面/命令行应用程序?
最佳答案
因此,我终于在不设置Web服务器和执行回调的情况下正常运行了。违反直觉的诀窍是关闭“桌面应用程序”设置,而不是请求offline_access
。FaceBook::Graph
对发布视频的支持目前似乎无法正常工作,因此我最终在Ruby中完成了此工作。
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
)
