Question

我有一个具有此OperationContract

的Restful服务

[OperationContract]
[WebInvoke(Method = "POST",
  ResponseFormat = WebMessageFormat.Json,
  BodyStyle = WebMessageBodyStyle.Wrapped,
  UriTemplate = "json")]
Response JSONData(Request request);

并以这种方式配置

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>

请求对象以这种方式形成

[DataContract]
public class Query
{
    [DataMember]
    public string name { get; set; }

    [DataMember]
    public string birthDate { get; set; }
}

[DataContract]
public class Input
{
    [DataMember]
    public Query query { get; set; }

    [DataMember]
    public string login_username { get; set; }

    [DataMember]
    public string login_password { get; set; }
}

[DataContract]
public class Request
{
    [DataMember]
    public Input input { get; set; }
}

我创建了一个小客户端来测试此查询，我也使用WCFTestClient对其进行了测试，并且工作正常。如果我尝试通过提琴手访问此内容，但我收到415 Unsupported Media Type错误。

我以下面的方式尝试了这个

POST, http://localhost:8080/HostDevServer/SearchService.svc/json, HTTP/1.1

User-Agent: Fiddler
Content-Type: application/json;charset=UTF-8
Host: localhost:8080
Content-Length: 368

{ "input": { "login_password": "pass", "login_username": "login name", "query": { "birthDate": "", "name": "robert" } } }

我也尝试过部署此服务，看看fiddler是否能够访问它，但事情变得更加混乱，因为现在我没有得到415 400抱怨'Reference to an object not set to an instance of the object.' {1}}我创建的小命令行客户端会抱怨There was no endpoint listening at我的服务位置。

我的问题是，我的配置文件有问题，还是我以错误的方式撰写了fiddler请求？如果是，我该如何解决这个问题，以便我能正常访问我的服务？

我可以看到您正在使用BodyStyle = WebMessageBodyStyle.Wrapped

这意味着您需要使用OperationContract期望的变量名称包装实际数据。总之，这应该工作

{ "response": { "input": { "login_password": "pass", "login_username": "login name", "query": { "birthDate": "", "name": "robert" } } } }

如果您想保持身体内容不变，那么建议您使用Bare代替Wrapped作为身体风格。
