ASP.NET发布到Facebook墙 [英] ASP.NET Post to Facebook Wall

问题描述

我试图张贴到Facebook涂鸦墙，无使用API​​，如C＃的Facebook SDK。我得到正确的访问令牌和所有这一切，但我发现了一个禁止使用403以下code：

 保护串postToWall（）
{
    VAR的accessToken =会话[_ FB_ACCESS_TOKEN];
    VAR graphId =会话[_ FB_USER_GRAPH_ID];    VAR URL =的String.Format（
        https://graph.facebook.com/{0}/feed
        graphId
    ）;    VAR REQ = WebRequest.Create（URL）;
    req.Method =POST;
    req.Co​​ntentType =应用/的X WWW的形式urlen codeD;    字符串POSTDATA =的String.Format（
        @卷曲-F'ACCESS_TOKEN = {0}-F的消息=这是一个测试......https://graph.facebook.com/{1}/feed
        的accessToken，
        graphId
    ）;    字节[]的字节数组= Encoding.UTF8.GetBytes（POSTDATA）;
    VAR流= req.GetRequestStream（）;
    stream.Write（字节数组，0，byteArray.Length）;
    stream.Close（）;    WebResponse的响应= req.GetResponse（）;
    Console.WriteLine（（（HttpWebResponse）响应）.StatusDescription）;
    流= response.GetResponseStream（）;
    StreamReader的读者=新的StreamReader（流）;    返回reader.ReadToEnd（）;
}
 

解决方案

您不应张贴卷曲-F ......作为POST请求的主体。卷曲是一个命令行工具，使您可以以http交互。你想发布到 https://graph.facebook.com/ {} graphId /供稿？=的access_token {}令牌与 POSTDATA 是消息=这是一个测试，在与他们的价值观括号替换的东西。

I'm trying to post to a facebook wall, without using an API such as the C# Facebook SDK. I'm correctly getting the access token and all that, but I'm getting a 403 forbidden using the following code:

protected string postToWall()
{
    var accessToken = Session["_FB_ACCESS_TOKEN"];
    var graphId = Session["_FB_USER_GRAPH_ID"];

    var url = string.Format(
        "https://graph.facebook.com/{0}/feed",
        graphId
    );

    var req = WebRequest.Create(url);
    req.Method = "POST";
    req.ContentType = "application/x-www-form-urlencoded";

    string postData = string.Format(
        @"curl -F 'access_token={0}' -F 'message=This is a test...' https://graph.facebook.com/{1}/feed",
        accessToken,
        graphId
    );

    byte[] byteArray = Encoding.UTF8.GetBytes(postData);
    var stream = req.GetRequestStream();
    stream.Write(byteArray, 0, byteArray.Length);
    stream.Close();

    WebResponse response = req.GetResponse();
    Console.WriteLine(((HttpWebResponse)response).StatusDescription);
    stream = response.GetResponseStream();
    StreamReader reader = new StreamReader(stream);

    return reader.ReadToEnd();
}

解决方案

You shouldn't be posting curl -F... as the body of the post request. curl is a command line utility that allows you to interact with http. You want to post to an https://graph.facebook.com/{graphId}/feed?access_token={token} with the postData being "message=This is a test" replacing things in brackets with their values.
