Question

我正在尝试使用python sdk上传图片：

代码：

graph = facebook.GraphAPI(self.current_user.access_token)
graph.put_object("me", "photos", name = "test", message = raw_picture_data)

但我收到错误"GraphAPIError: (#324) Requires upload file"。我不认为它是权限问题，因为我已经请求perms =“user_photos，friends_photos，publish_stream”。有谁知道这个错误意味着什么以及如何解决它？

Answer 1

我使用此库对图像进行编码：http://atlee.ca/software/poster/

将此添加到facebook.py：

from poster.encode import *
from poster.streaminghttp import register_openers

def put_photo(self, source, album_id=None, message=""):
    object_id = album_id or "me"

    register_openers()
    content_type,body = multipart_encode( [ ('message',message),('access_token',self.access_token),('source',source) ] )

    req = urllib2.Request("https://graph.facebook.com/%s/photos" % object_id, content_type,body )

    try:
        data = urllib2.urlopen(req).read()
    except urllib2.HTTPError as e:
        data = e.read() 
    try:
        response = _parse_json(data)
        if response.get("error"):
            raise GraphAPIError(response["error"].get("code", 1),response["error"]["message"])
    except ValueError:
        response = data

    return response

将照片调用为像对象一样的文件：

graph = facebook.GraphAPI(access_token)
photo = open("myphoto.bmp","rb")
graph.put_photo(photo,"me","This is my brilliant photo")

put_photo方法已被某人（我忘记了谁）提交为提议添加到API的函数但是在我使用海报对图像进行编码之前它对我不起作用。

希望这有帮助。

也许你可以试试这个。 http://od-eon.com/blogs/tudor/facebook-photo-upload-google-app-engine/

我试图将此用于solved my problem，但我收到了此回复 -
{“error”：{“type”：“OAuthException”，“message”：“在传递访问令牌时必须使用https：//”}}

稍微与类似的错误作斗争。我没有使用SDK，只是对graphapi的POST。对我来说，这个错误发生在我没有提供文件名到发送到Facebook的“表单”中的文件上传字段。这是我的代码（海报 - http://pypi.python.org/pypi/poster/0.8.1）

from poster.encode import multipart_encode, MultipartParam
url = 'https://graph.facebook.com/me/photos?access_token=%s'%model.facebook_token
file_param = MultipartParam(name = 'source',
                            filename = 'photo.jpg', #this is crucial!!!
                            fileobj = blob_reader) #the blob reader is the fileobject for the file (with read() method)
message_param = MultipartParam(name = 'message',
                               value = 'test message')                                

datagen, headers = multipart_encode([file_param,
                                     message_param])
from google.appengine.api import urlfetch
result = urlfetch.fetch(url, 
               payload = ''.join(datagen), 
               headers = headers,
               method = 'POST')     
return result.content

GraphAPIError：（＃324）需要上传文件
