IIS asp.net C＃API发布方法错误“远程服务器返回错误：403禁止”

问题描述

我已经通过gupshup创建了一个viber机器人。我在Win 10中使用IIS服务器运行WebForm应用程序。我尝试通过api post方法向viberbot发送消息，但c＃勒死了我。（我成功测试了网址和参数）

这是我的代码：

protected void viber_msg(String viberid,String strmsg)
{
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://api.gupshup.io/sm/api/bot/mybotname/msg?apikey=mykey");
    httpWebRequest.ContentType = "application/x-www-form-urlencoded";
    httpWebRequest.Method = "POST";

   
    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
        string json = "context={'botname':'mybotname','channeltype':'viber','contextid':'viberid','contexttype':'p2p'}&message="+strmsg;
        streamWriter.Write(json);
    }
    
    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();

    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
    {
        var result = streamReader.ReadToEnd();
    }
}

protected void Button1_Click(object sender,EventArgs e)
{
    viber_msg("viberuserID","This is a message");
}

我遇到的错误是“ System.Net.WebException: 'The Remote Server returned an error: (403) Forbidden.'” 还尝试过POSTMAN并获得"message": "Invalid authentication credentials" 提前谢谢...

解决方法

protected void viber_msg(String viberid,String message)
{
    var client = new RestClient("https://api.gupshup.io/sm/api/bot/mybot/msg?apikey=myapikey");
    client.Timeout = -1;
    var request = new RestRequest(Method.POST);
    request.AddHeader("Content-Type","application/x-www-form-urlencoded");
    request.AddParameter("context","{\"botname\": \"mybot\",\"channeltype\" :\"viber\",\"contextid\": \""+viberid+"\",\"contexttype\": \"p2p\"}");
    request.AddParameter("message",message);
    IRestResponse response = client.Execute(request);
} 

protected void Button1_Click(object sender,EventArgs e)
{
    viber_msg("viberid","message");
}

}

RestSharp库！！！
