与邮递员相比，Restsharp 会抛出通用错误消息

Question

当我使用邮递员并输入不完整的 MD 哈希值时，它会正确显示 MD 哈希值有问题的错误：

但是当我尝试使用 Restsharp 在 C# 中执行相同操作时，我总是收到通用错误消息“请求失败，状态代码为 BadRequest”。 如果我输入错误的数据库名称或错误的密码或用户名，我只会收到一条错误消息。与此同时，我在邮递员中收到了确切的消息。

C#代码：

using RestSharp;

var client = new RestClient("URL");
var request = new RestRequest();

//request.AddBody("Grant_type=password&Scope=Innovator&Client_id=IOMApp&Username=vipul&Password=21c603dbf852f78063f98674640ab339&Database=DATABASENAME");

//request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
//request.AddParameter("Grant_type", "password");
//request.AddParameter("Scope", "Innovator");
//request.AddParameter("Client_id", "IOMApp");
//request.AddParameter("Username", "vipul");
//request.AddParameter("Password", "21c603dbf852f78063f98674640ab33");
//request.AddParameter("Database", "DATABASENAME");

request.AddObject (new
{
    Grant_type = "password",
    Scope = "Innovator",
    Client_id = "IOMApp",
    Username = "vipul",
    Password = "21c603dbf852f78063f98674640ab33",
    Database = "DATABASENAME"
});

var response = client.Post(request);

当我使用错误的 MD Hash 时的 C# 输出

System.Net.Http.HttpRequestException
  HResult=0x80131500
  Message=Request failed with status code BadRequest
  Source=RestSharp
  StackTrace:

请求失败，状态代码为 BadRequest

有人可以帮我解决这个问题吗？

Answer 1

我用过

    var response = await client.PostAsync(uri, content);
    var result = await response.Content.ReadAsStringAsync();

这解决了我的问题，我没有抛出异常，而是在变量中得到了正确的响应。
