Question

我试图在Facebook墙上发帖，没有使用C＃Facebook SDK之类的API。我正确地获取了访问令牌以及所有这些，但我使用以下代码禁止403：

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();
}

你不应该发布curl -F ...作为帖子请求的正文。 curl是一个命令行实用程序，允许您与http进行交互。您想发布到https://graph.facebook.com/ {graphId} / feed？access_token = {token}，postData为“message =这是一个测试”，用括号替换括号中的内容。

ASP.NET发布到Facebook Wall
