Question

我的Web API控制器中有一个POST方法，如下所示

public class StudentsController : ApiController {
  public HttpResponseMessage Post(ApiStudent apiModel) {
    // does processing here
  }
}

public class ApiStudent {
  public long Id { get; set; }
  public string FirstName { get; set; }
  public string LastName { get; set; }
  public int GraduationClass { get; set; }
  // other fields omitted for brevity
}

在cilent 1中，我将ApiStudent直接添加到REST客户端的主体，这导致JSON没有转义字符。这在服务器端正确地自动反序列化，但是对于客户端2，当我使用转义字符发送JSON内容时，ApiStudent反序列化为NULL。

// DESERIALIZES PROPERLY ON SERVER
public void Client1() {
    var student = new ApiStudent();
    student.Id = 0; // new student since it's a post
    student.FirstName = "Homer";
    student.LastName = "Simpson";
    student.GraduationClass = 2014;

    var jsonRequest = new RestRequest("http://www.mydomain.com/api/students", Method.POST); 
    jsonRequest.RequestFormat = DataFormat.Json;
    jsonRequest.AddBody(student);
    IRestResponse jsonResponse = client.Execute(jsonRequest);            
    return jsonResponse;
}

// DESERIALIZES AS NULL ON SERVER
public void Client2() {
    var jsonContent = "{ \"FirstName\": \"Api\", \"LastName\": \"Test\",  \"GraduationClass\": 2014, \"Id\": 0 }";

    var jsonRequest = new RestRequest("http://www.mydomain.com/api/students", Method.POST); 
    jsonRequest.RequestFormat = DataFormat.Json;
    jsonRequest.AddBody(jsonContent);
    IRestResponse jsonResponse = client.Execute(jsonRequest);            
    return jsonResponse;
}

使用fidder，我可以看到客户端1通过以下内容发送：

{ "FirstName": "Api", "LastName": "Test",  "GraduationClass": 2014, "Id": 0 }

我可以看到客户端2通过以下内容发送：

{ \"FirstName\": \"Api\", \"LastName\": \"Test\",  \"GraduationClass\": 2014, \"Id\": 0 }

有没有办法去除转义字符，或者在服务器端正确解析它们？

我找到了一个解决方法，我希望它可以帮助某人。

// NOW DESERIALIZES PROPERLY ON THE SERVER
public void Client2() {
    var jsonContent = "{ \"FirstName\": \"Api\", \"LastName\": \"Test\",  \"GraduationClass\": 2014, \"Id\": 0 }";

    var jsonRequest = new RestRequest("http://www.mydomain.com/api/students", Method.POST); 
    jsonRequest.AddParameter("text/json", jsonContent, ParameterType.RequestBody);
    IRestResponse jsonResponse = client.Execute(jsonRequest);            
    return jsonResponse;
}
