facebook python-sdk post_to_wall附件 [英] facebook python-sdk post_to_wall attachment

问题描述

您好
我在谷歌appengine上使用python-sdk（http://github.com/facebook/python-sdk.git）。
我运行的是新闻源示例。

在facebook.py中，我必须导入urllib2

然后更改

  file = urllib.urlopen（https://graph.facebook.com/+ path +？+ 
 urllib.urlencode（args），post_data ）
  

to

 code> file = urllib2.urlopen（https://graph.facebook.com/+ path +？+ 
 urllib.urlencode（args），post_data）
  

现在基本的应用程序正常工作。但是，如果我在 facebookclient.py

中更改了

  try：
 self.graph.put_wall_post（message）
除了异常，e：
 self.response.out.write（e）
 return 
  / pre> 
 
 
到
  try：
 attachment = {} 
 message = message 
 caption ='test caption'
附件['caption'] = caption 
附件['name'] ='test name'
附件['description'] ='test description'
 self.graph.put_wall_post（message，attachment = attachment）
除了异常，e：
 self.response.out.write（e） 
 return 
  
我会收到错误（在 http：// localhost：8080 ）：
 
 HTTP错误400：错误请求
 
和appengine开发服务器抱怨：

解决方案
通过使用put_object来解决问题的post_to_wall：
 
请参阅 http://developers.facebook.com/ docs / reference / api / post 为例，介绍如何发布卷曲
  self.graph.put_object（me，feed，message = message，
 link = http://leona-nachhilfe.appspot.com，
 picture =http://leona-nachhilfe.appspot.com/static/images/logo.png，
 name =LeONa-测验，
 description =Orges erreichte 45.Punkte，
 actions = {'name'：'Zu den Quiz-Aufgaben'，'link'：'http：//leona-nachhilfe.appspot .com'}，
 privacy = {'value'：'ALL_FRIENDS'} 
）
  
 
Hi
I am using the python-sdk (http://github.com/facebook/python-sdk.git) on google appengine.
I am runnig the "newsfeed" example.

In facebook.py i had to import urllib2

and then change 
file = urllib.urlopen("https://graph.facebook.com/" + path + "?" +
                          urllib.urlencode(args), post_data)  
to   
file = urllib2.urlopen("https://graph.facebook.com/" + path + "?" +
                          urllib.urlencode(args), post_data)  
Now the basic application works. However if I change

in facebookclient.py  
    try:  
        self.graph.put_wall_post(message)  
    except Exception, e:  
        self.response.out.write(e)  
        return  
to  
    try:  
        attachment = {}  
        message = message         
        caption = 'test caption'  
        attachment['caption'] = caption  
        attachment['name'] = 'test name'  
        attachment['description'] = 'test description'  
        self.graph.put_wall_post(message, attachment=attachment)  
    except Exception, e:  
        self.response.out.write(e)  
        return  
i will get the error (on http://localhost:8080) :

     HTTP Error 400: Bad Request

and the appengine development server complains:

         INFO     2010-10-24 17:20:44,483 dev_appserver.py:3275] "POST /post HTTP/1.1" 302 -

解决方案
Solved the problem by using put_object instead of post_to_wall:

see http://developers.facebook.com/docs/reference/api/post for an example on how to post with curl
 self.graph.put_object("me", "feed", message=message,  
                             link="http://leona-nachhilfe.appspot.com",  
                             picture="http://leona-nachhilfe.appspot.com/static/images/logo.png",    
                             name = "LeONa-Quiz",    
                             description = "Orges erreichte 45.Punkte",
                             actions = {'name': 'Zu den Quiz-Aufgaben', 'link': 'http://leona-nachhilfe.appspot.com'},
                             privacy = {'value': 'ALL_FRIENDS'}
                             )
