C# 从C中的OperationContext读取JSON格式的请求内容#

我创建了WCF RESTful服务，如下所示：

[OperationContract]
[WebInvoke(Method = "PUT",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "/Customer/{customerID}/profile")]
string PutCustomerProfileData(string customerID);

{<root type="object">
  <customerID type="string">RC0064211</customerID>
  <TermsAgreed type="string">true</TermsAgreed>
</root>}

public string PutCustomerVerificationData(string customerID, CustomerVerification customerVerification)
{
      JavaScriptSerializer js = new JavaScriptSerializer();
      string requestBody = js.Serialize(customerVerification);
      string serviceResponse = bllCustomerDetails.PutCustomerVerificationData(customerID, requestBody).Replace("\"", "'");
      return serviceResponse;
}

我正在使用Postman调试它，并在正文中传递JSON数据，如下所示：

[OperationContract]
[WebInvoke(Method = "PUT",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "/Customer/{customerID}/profile")]
string PutCustomerProfileData(string customerID);

{<root type="object">
  <customerID type="string">RC0064211</customerID>
  <TermsAgreed type="string">true</TermsAgreed>
</root>}

public string PutCustomerVerificationData(string customerID, CustomerVerification customerVerification)
{
      JavaScriptSerializer js = new JavaScriptSerializer();
      string requestBody = js.Serialize(customerVerification);
      string serviceResponse = bllCustomerDetails.PutCustomerVerificationData(customerID, requestBody).Replace("\"", "'");
      return serviceResponse;
}

{“customerID”：“RC0064211”，“TermsAgreed”：“true”}

它在RequestMessage中返回的内容如下：

[OperationContract]
[WebInvoke(Method = "PUT",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "/Customer/{customerID}/profile")]
string PutCustomerProfileData(string customerID);

{<root type="object">
  <customerID type="string">RC0064211</customerID>
  <TermsAgreed type="string">true</TermsAgreed>
</root>}

public string PutCustomerVerificationData(string customerID, CustomerVerification customerVerification)
{
      JavaScriptSerializer js = new JavaScriptSerializer();
      string requestBody = js.Serialize(customerVerification);
      string serviceResponse = bllCustomerDetails.PutCustomerVerificationData(customerID, requestBody).Replace("\"", "'");
      return serviceResponse;
}

{
RC0064211
真的
}

我想要这个JSON格式的请求主体。能给我吗？如果没有，我可以用什么方法为前面提到的

RequestMessage

创建JSON字符串？

在要转换为JSON的成员变量上添加[DataMember]

事实上，我并不完全理解这个问题，但作为一个建议，我可能会建议：

您应该像这样为Json设计WebConfig

    <services>
  <service name="Your Service Name"

    <endpoint address="" behaviorConfiguration="webHttp" binding="webHttpBinding"
              bindingConfiguration="webHttpBindingWithJsonP" contract="YourProjectName">

    </endpoint>
  </service>
</services>
<bindings>
  <webHttpBinding>
    <binding name="webHttpBindingWithJsonP" />

             </binding>
  </webHttpBinding>
</bindings>


<behaviors>
  <endpointBehaviors>
    <behavior name="webHttp">
      <webHttp />
    </behavior>
  </endpointBehaviors>

另外，您可以在Fiddler 4上尝试您的Web服务，您可以请求和响应JSON或您想要的内容。

我尝试了

DataContract

和

DataMember

，它对我很有效

下面是示例代码：

[OperationContract]
    [WebInvoke(Method = "PUT",
        RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json,
        UriTemplate = "/Customer/{customerID}/verification")]
    string PutCustomerVerificationData(string customerID, CustomerVerification customerVerification);
}

[DataContract]
public class CustomerVerification
{
    [DataMember]
    public string PasswordHash { get; set; }

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

然后，我将该DataContract转换为JSON字符串，并进一步使用它，如下所示：

[OperationContract]
[WebInvoke(Method = "PUT",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "/Customer/{customerID}/profile")]
string PutCustomerProfileData(string customerID);

{<root type="object">
  <customerID type="string">RC0064211</customerID>
  <TermsAgreed type="string">true</TermsAgreed>
</root>}

public string PutCustomerVerificationData(string customerID, CustomerVerification customerVerification)
{
      JavaScriptSerializer js = new JavaScriptSerializer();
      string requestBody = js.Serialize(customerVerification);
      string serviceResponse = bllCustomerDetails.PutCustomerVerificationData(customerID, requestBody).Replace("\"", "'");
      return serviceResponse;
}

您可以尝试在Postman中添加

Accept:application/json

头。但老实说，这不可能是您的

PutCustomerProfileData

的实际代码-您返回的是什么？我已经设置了该标题，但无论如何也帮不了我。对于

PutCustomerProfileData

，它将只返回带有正确消息的JSON格式。

PutCustomerProfileData

显然不会返回JSON，因为您看到的是XML。您能否粘贴

PutCustomerProfileData

的完整代码（或至少与构建输出字符串相关的所有内容）。如果可能，您能否提供一些代码示例，因为我不知道如何使用

DataMember

你提到的是同一个问题吗？不，大约6个月前我就遇到了这个问题，所以[DataMember]为我修复了这个问题。
