您好,我用的是 c# 的调用,以下是 C# 的 API 文档中的调用代码,测试的时候会在红色字体的地方报这个异常 String authHost = "https://aip.baidubce.com/oauth/2.0/token"; HttpClient client = new HttpClient(); List<KeyValuePair<String, String>> paraList = new List<KeyValuePair<string, string>>(); paraList.Add(new KeyValuePair<string, string>("grant_type", "client_credentials")); paraList.Add(new KeyValuePair<string, string>("client_id", clientId)); paraList.Add(new KeyValuePair<string, string>("client_secret", clientSecret)); HttpResponseMessage response = client.PostAsync(authHost, new FormUrlEncodedContent(paraList)).Result; result = response.Content.ReadAsStringAsync().Result; Console.WriteLine(result); return result;

这是啥语言调用呢?一般接口都会返回json格式的字符串

您好,我用的是 c# 的调用,以下是 C# 的 API 文档中的调用代码,测试的时候会在红色字体的地方报这个异常

String authHost = "https://aip.baidubce.com/oauth/2.0/token";
HttpClient client = new HttpClient();
List> paraList = new List>();
paraList.Add(new KeyValuePair("grant_type", "client_credentials"));
paraList.Add(new KeyValuePair("client_id", clientId));
paraList.Add(new KeyValuePair("client_secret", clientSecret));

HttpResponseMessage response = client.PostAsync(authHost, new FormUrlEncodedContent(paraList)).Result;
result = response.Content.ReadAsStringAsync().Result;
Console.WriteLine(result);
return result;
