我试图使用GET方法而不是POST方法用于我的程序，这必然取决于HTTPWEBREQUEST .. 这是我使用的代码

    Dim postData As String = "GET /fbml/ajax/dialog/apprequests?message=Here%27s%20a%20Anvil%20for%20your%20pet%20in%20Wild%20Ones!%20Could%20you%20help%20me%20by%20sending%20a%20gift%20back%3F&data=[%7B%22request_type%22%3A%22gift_v2%22%2C%20%22gift%22%3A%22anvil%22%7D%2C%7B%22track%22%3A%22invite-Gift-request2-anvil-20120112-0%22%7D]&to=[%22100003034461289%22]&e2e=%7B%7D&app_id=101628414658&locale=en_US&sdk=joey&display=async&frictionless=true&redirect_uri=https%3A%2F%2Fwild-fb-apache-active-vip.playdom.com%2Fpub%2Fphp%2F&__d=1&__user=1668282525&__a=1&__dyn=7n8ahyj3419Aw&__req=3 HTTP/1.1"
    Dim tempCookies As New CookieContainer
    Dim encoding As New UTF8Encoding
    Dim byteData As Byte() = encoding.GetBytes(postData)

    Dim postReq As HttpWebRequest = DirectCast(WebRequest.Create("https://apps.facebook.com/fbml/ajax/dialog/apprequests?message=Here%27s%20a%20Anvil%20for%20your%20pet%20in%20Wild%20Ones!%20Could%20you%20help%20me%20by%20sending%20a%20gift%20back%3F&data=[%7B%22request_type%22%3A%22gift_v2%22%2C%20%22gift%22%3A%22anvil%22%7D%2C%7B%22track%22%3A%22invite-Gift-request2-anvil-20120112-0%22%7D]&to=[%22100003034461289%22]&e2e=%7B%7D&app_id=101628414658&locale=en_US&sdk=joey&display=async&frictionless=true&redirect_uri=https%3A%2F%2Fwild-fb-apache-active-vip.playdom.com%2Fpub%2Fphp%2F&__d=1&__user=1668282525&__a=1&__dyn=7n8ahyj3419Aw&__req=3"), HttpWebRequest)
