c# 后台调用msgSecCheck验证文本内容安全，返回值 {strategy: "keyword",errcode: 0,strategy: "keyword",errcode: 0,strategy: "keyword",errcode: 0, strategy: "content_model",errcode: 0,errcode: 0,errmsg: "ok",trace_id: "63b53f64-539c0acd-132f3c5d", detail: [{strategy: "content_model", errcode: 0,strategy: "content_model",errcode: 0,strategy: "keyword",errcode: 0,strategy: "keyword", errcode: 0,strategy: "content_model",errcode: 0,suggest: "pass",label: 100,prob: 90,}, {strategy: "keyword",errcode: 0,},], result: {suggest: "pass",label: 100,},} 使用的测试词条如下(官方给的测试用例)，始终都是通过， #代码如下： byte[] bytes = Encoding.Default.GetBytes(body.content); string content = Encoding.UTF8.GetString(bytes); Dictionary<string, object> par = new Dictionary<string, object> { { "openid",d.openId},{ "scene",4}, { "version",2}, { "content",content} }; HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);             req.Method = "POST";             req.ContentType = "application/json; charset=UTF-8";             StringBuilder builder = new StringBuilder();             builder.Append(JsonHelper.SerializeJson(par));             byte[] data = Encoding.UTF8.GetBytes(builder.ToString());             req.ContentLength = data.Length;             using (Stream reqStream = req.GetRequestStream())             {                 reqStream.Write(data, 0, data.Length);                 reqStream.Close();             }             HttpWebResponse resp = (HttpWebResponse)req.GetResponse();             Stream stream = resp.GetResponseStream();             using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))             {                 backMsg = reader.ReadToEnd();             } 奇怪的很
