以编程方式获取使用Facebook Graph API的访问令牌 [英] Programmatically getting an access token for using the Facebook Graph API

问题描述

我正在尝试使用一个bash或者python脚本来播放facebook图形API。使用API​​看起来很简单，但是我无法在我的bash脚本中设置curl来调用authorize和access_token。有没有人有一个工作的例子？

解决方案

更好的晚于从未，也许其他人搜索会找到它。我在MacBook上使用Python 2.6。

这需要你有

• 安装了Python facebook模块： https://github.com/pythonforfacebook/facebook-sdk，


• 一个实际的Facebook应用设置


• ，您要发布的个人资料必须已经授予适当的权限才能允许所有不同的内容阅读和写作。

您可以在Facebook开发人员文档中阅读有关身份验证的内容。有关详细信息，请参见 https://developers.facebook.com/docs/authentication/ 。 p>

这里：

 ＃！ / usr / bin / python 
＃code：utf-8 
 
 import facebook 
 import urllib 
 import urlparse 
 import subprocess 
 import warnings 
 
＃隐藏废弃警告。 Facebook模块不是最新的（facebook.GraphAPIError）。 
 warnings.filterwarnings（'ignore'，category = DeprecationWarning）
 
 
＃您的应用程序的参数和您想要混淆的配置文件的ID。 
 FACEBOOK_APP_ID ='XXXXXXXXXXXXXXX'
 FACEBOOK_APP_SECRET ='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
 FACEBOOK_PROFILE_ID ='XXXXXX'
 
 
＃尝试获取访问令牌。很尴尬
 oauth_args = dict（client_id = FACEBOOK_APP_ID，
 client_secret = FACEBOOK_APP_SECRET，
 grant_type ='client_credentials'）
 oauth_curl_cmd = ['curl'，
'https：// graph.facebook.com/oauth/access_token？'+ urllib.urlencode（oauth_args）] 
 oauth_response = subprocess.Popen（oauth_curl_cmd，
 stdout = subprocess.PIPE，
 stderr = subprocess.PIPE ）.communicate（）[0] 
 
 try：
 oauth_access_token = urlparse.parse_qs（str（oauth_response））['access_token'] [0] 
除了KeyError：
 print（'无法抓取访问令牌！'）
 exit（）
 
 facebook_graph = facebook.GraphAPI（oauth_access_token）
 
 
＃尝试在墙上张贴东西。 
尝试：
 fb_response = facebook_graph.put_wall_post（你好，从Python，\ 
 profile_id = FACEBOOK_PROFILE_ID）
打印fb_response 
除了facebook.GraphAPIError为e：
打印出错了，e.type，e.message 
  

错误检查获得令牌可能会更好，但您可以了解该做什么。

I am trying to put together a bash or python script to play with the facebook graph API. Using the API looks simple, but I'm having trouble setting up curl in my bash script to call authorize and access_token. Does anyone have a working example?

解决方案

Better late than never, maybe others searching for that will find it. I got it working with Python 2.6 on a MacBook.

This requires you to have

• the Python facebook module installed: https://github.com/pythonforfacebook/facebook-sdk,
• an actual Facebook app set up
• and the profile you want to post to must have granted proper permissions to allow all the different stuff like reading and writing.

You can read about the authentication stuff in the Facebook developer documentation. See https://developers.facebook.com/docs/authentication/ for details.

This blog post might also help with this: http://blog.theunical.com/facebook-integration/5-steps-to-publish-on-a-facebook-wall-using-php/

Here goes:

#!/usr/bin/python
# coding: utf-8

import facebook
import urllib
import urlparse
import subprocess
import warnings

# Hide deprecation warnings. The facebook module isn't that up-to-date (facebook.GraphAPIError).
warnings.filterwarnings('ignore', category=DeprecationWarning)


# Parameters of your app and the id of the profile you want to mess with.
FACEBOOK_APP_ID     = 'XXXXXXXXXXXXXXX'
FACEBOOK_APP_SECRET = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
FACEBOOK_PROFILE_ID = 'XXXXXX'


# Trying to get an access token. Very awkward.
oauth_args = dict(client_id     = FACEBOOK_APP_ID,
                  client_secret = FACEBOOK_APP_SECRET,
                  grant_type    = 'client_credentials')
oauth_curl_cmd = ['curl',
                  'https://graph.facebook.com/oauth/access_token?' + urllib.urlencode(oauth_args)]
oauth_response = subprocess.Popen(oauth_curl_cmd,
                                  stdout = subprocess.PIPE,
                                  stderr = subprocess.PIPE).communicate()[0]

try:
    oauth_access_token = urlparse.parse_qs(str(oauth_response))['access_token'][0]
except KeyError:
    print('Unable to grab an access token!')
    exit()

facebook_graph = facebook.GraphAPI(oauth_access_token)


# Try to post something on the wall.
try:
    fb_response = facebook_graph.put_wall_post('Hello from Python', \
                                               profile_id = FACEBOOK_PROFILE_ID)
    print fb_response
except facebook.GraphAPIError as e:
    print 'Something went wrong:', e.type, e.message

Error checking on getting the token might be better but you get the idea of what to do.
