Facebook粉丝专页应用传递字符串到app_data并检索 [英] Facebook fan page app pass string to app_data and retrieve

问题描述

我有一个多页面Facebook的粉丝页面应用程序在asp.net c＃。我如何设置和检索该app_data querystring？是这部分的签名请求或实际的网页的粉丝页面？我可以使用以下命令获得signed_request：

如果（！string.IsNullOrEmpty（signedRequest））
{
动态SignedRequestData;

  
 var DecodedSignedRequest = FacebookWebContext.Current.SignedRequest.Data; 
 SignedRequestData = DecodedSignedRequest 
  

所以基本上在第一页我想得到signed_reqeuest使用然后将其附加到app_data querystring中的url。在所有其他请求我可以得到这一点，并使用这些值来检查用户状态，喜欢，登录等。这样我认为这将阻止跨域cookie问题在safari。任何人都同意或不同意这一点？

有没有人这样做？

欢呼

解决方案

您可以将 app_data 设置为：

？

https://www.facebook.com/ {PAGE_ID} SK = {APP_ APP_ID}&安培; app_data文件= { KEY1： VALUE1， KEY2： VALUE2}

您可以将多个值传递到 app_data 中，并将其返回 signed_request 以您的实际页面（POST数据）。

您应该做的是获取 signed_request 在第一页从POST加载，并将其添加到您的应用程序的URL为 ...？signed_request = {signed_request_string} 。每个页面都应该在URL中传递，以便您可以轻松查看，如和 admin 页。您不需要为此使用 app_data 。无论如何，在应用程序中随后的任何点击/重定向之后，数据将会丢失。

Hi i have a multiple page facebook fan page app in asp.net c#. how do i set and retrieve that app_data querystring? is this part of the signedrequest or the actual url of the fan page? will there be cross domian issues in getting this in safari and ie?

i can get the signed_request using the following:

 if (!string.IsNullOrEmpty(signedRequest))
{
    dynamic SignedRequestData;
    var DecodedSignedRequest = FacebookWebContext.Current.SignedRequest.Data;
    SignedRequestData = DecodedSignedRequest

so basically on the first page i want to get the signed_reqeuest using the above and then append this to the url in app_data querystring. on all other requests i can then get this and use those values to check user status, liked, logged in etc. This way i think it will stop the cross domain cookie issues in safari. anyone agree or disagree with this?

has anyone done this?

cheers

解决方案

You can set the app_data as:

https://www.facebook.com/{page_id}?sk=app_{app_id}&app_data={"key1":"value1","key2":"value2"}

You can pass multiple values into app_data and it will be returned in the signed_request to your actual page as (POST data).

What you should really do is get the signed_request on first page load from POST, and add it to the URL of your app as ...?signed_request={signed_request_string}. Every page should then pass this around in the URL so you can easily check the like and admin status from any sub-page. You don't need to use app_data for this. And in any case, the data will be lost after the any subsequent click / redirect in your app.
