Facebook App托管在Google App Engine上 [英] Facebook app hosted on Google App Engine

问题描述

我是Facebook的新手，我有一个应用已经在GAE上运行（使用python）。我想将其与Facebook集成，以便我可以访问一些用户的数据，以帮助我个性化应用程序（数据，如喜欢的页面，兴趣，他们在哪里等）。而且还要分享应用程序的输出以供朋友们看到。

我以为我会在 https://developers.facebook.com/

我不知道从哪里开始，有一些教程（大多数都是非常老的，一些使用的脚本被弃用，所以有点担心），还有FBML ..我想，也许我可以得到相同的数据只使用Facebook的登录然后使用FQL访问这些数据。

我不知道我是否会遇到这个新的https限制（Facebook说，这是需要截至2011年10月拥有SSL证书）。

所以底线..我从哪里开始？

解决方案

这里我们去：

从这个链接下载： https://github.com/jgorset/facepy/tree/master/facepy ：

从下载，您将具有：
$ code> signed_request.py 来解析Facebook的
画布url将发布的signed_request： https：// POST 方法中的apps.facebook.com/myapp

和 graph_api.py 使操作变为 graphapi https://developers.facebook.com/docs/reference/api/

注意：您将包括access_token来自facebook js sdk写的cookies。

for fb js sdk看到这个答案： http s：//stackoverflow.com/a/8625873/492258 的部分

在您的索引页面：

  fb_app_secret ='abcd ...'
 fb_app_id = 123345 
 def index（request）：
如果request.POST：
 signed_request_param = request.POST.get（'signed_request）
如果signed_request_param：
＃signed_request.py 
 signed_request_dic = signed_request.parse_signed_request（signed_request_param，fb_app_secret）
如果signed_request_dic：
如果signed_request_dic.has_key（'user_id'）：
 fb_uid = signed_request_dic ['user_id'] 
＃你有你的男人以前被授权你的fb应用程序：mypp 
  

对于连续呼叫，您将使用我上面提到的Cookie：

  def my_page（request）：
 my_dict =无
 my_dict = signed_request.get_user_from_cooki e（request.COOOKIES，fb_app_id，fb_app_secret）
如果my_dict：
如果my_dict.has_key（'uid'）：
 fb_uid = my_dict ['uid'] 
 fb_uid = int （fb_uid）
＃你再次收到你的注册用户。 
  

为了注册，从fb js sdk最简单的方法，已经提到了

  #finally为SSL，在您的app.ymal中：
 
  -  url：。* 
脚本：django_bootstrap。 py 
安全：可选
  

不要忘记为Internet Explorer设置P3P，iframre cookie问题：

  def my_page（request）：
 .... 
 response = render_to_response（'mypage .html'，view_params）
响应[P3P] ='CP =IDC DSP COR ADM DEVI TAII PSA PSD IVAi IVDi CONI是我们的IND CNT'
返回响应
  




I am new to Facebook apps, I have an app already up and running on GAE (using python). I want to integrate it with Facebook so I can access some of the users' data to help me personalize the app (data like the liked pages, interests, where they are from etc..). And also to share the app's outputs to be seen by friends.

I thought I would go for the Facebook app option on https://developers.facebook.com/

I don't know where to start from, there are some tutorials (most of them are very old, some use scripts that are deprecated so it is a bit worrying), and there's FBML.. and I was thinking that maybe I can get the same data by only using Facebook's log in then use FQL to access these data.

And I don't know if I will get stuck with that new https restriction (Facebook says that it is required as of October 2011 to have an SSL certificate).

So bottom line.. where do I start?

解决方案

Here we go:

From this link do download: https://github.com/jgorset/facepy/tree/master/facepy:

from downloads, you will have:
signed_request.py to parse signed_request that will be posted by facebook in your canvas url: https://apps.facebook.com/myapp in POST method

and graph_api.py to make operation to graphapi https://developers.facebook.com/docs/reference/api/

note: you will be including access_token from cookies written by facebook js sdk.
for fb js sdk see this answer: https://stackoverflow.com/a/8625873/492258 of javascript part

in your index page:

fb_app_secret='abcd...'
fb_app_id = 123345
def index(request):
    if request.POST:
        signed_request_param = request.POST.get('signed_request)        
        if signed_request_param:  
            #signed_request.py 
            signed_request_dic = signed_request.parse_signed_request(signed_request_param, fb_app_secret)
             if signed_request_dic:
                if signed_request_dic.has_key('user_id'): 
                    fb_uid = signed_request_dic['user_id']
                    #you got your man that is previously authorized your fb app : mypp

for successive calls, you'll be using cookies that I mentioned above:

def my_page(request):
    my_dict = None
    my_dict = signed_request.get_user_from_cookie(request.COOOKIES, fb_app_id, fb_app_secret)
    if my_dict:
        if my_dict.has_key('uid'):            
            fb_uid = my_dict['uid']
            fb_uid = int(fb_uid)
            #you got your registered user again.

For registration, the easiest way doing from fb js sdk, already I mentioned

#finally for SSL, in your app.ymal:

- url: .*
  script: django_bootstrap.py
  secure: optional 

Don't forget to set P3P for internet explorer, iframre cookie issue:

def my_page(request):
    ....
    response = render_to_response('mypage.html', view_params )
    response["P3P"] = 'CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"'   
    return response
