C# 使用WCF Rest从URL获得Json格式响应

我想用POST方法从URL获取WCF Json请求。当我在C#中调用函数时，我接受了正确的请求，但当我将函数写入URL时，ı无法获得正确的结果。有人能帮我吗

这是我的Service1.svc文件 这是我的web.config文件

您应该将接口更改为

[OperationContract]
[WebInvoke(Method = "POST",
           RequestFormat = WebMessageFormat.Json,
           ResponseFormat = WebMessageFormat.Json,
           UriTemplate = "ChangePassword")]
LoginInformations ChangePassword(LoginInformations loginInformations);

并将json作为主体发送，但不作为查询参数发送

---

否则，您可以拆分登录名和密码并将其作为查询参数单独发送，但不建议这样做（很容易窃取您的凭据）

请在您的

IService1.svc

文件中尝试此操作

[OperationContract]
[WebInvoke(Method = "POST",
   RequestFormat = WebMessageFormat.Json,
   ResponseFormat = WebMessageFormat.Json,
   UriTemplate = "ChangePassword")]
LoginInformations ChangePassword(LoginInformations loginInformations);

[DataContract]
public class LoginInformations
{
    [DataMember]
    public string UserName { set; get; }
    [DataMember]
    public string Password { set; get; }
}

在您的

Service1.svc

文件中

    public LoginInformations ChangePassword(LoginInformations loginInformations)
    {
        try
        {
            loginInformations.Password = "654321";

            return loginInformations;
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

你能显示你不正确的结果吗？我编辑并添加了图片，你能显示不正确的结果吗？你能举一个例子说明ı如何调用Url吗？（比如像这样？@AnilKilic，是的，你也应该发送一个body，所以你需要使用一些应用程序，比如fiddler或plugin for browser，等等，我如何使用这个功能？我应该从url这样称呼它吗？如何从url发送此函数的参数？有人说我应该加小提琴手，但我不知道怎么做

[OperationContract]
[WebInvoke(Method = "POST",
   RequestFormat = WebMessageFormat.Json,
   ResponseFormat = WebMessageFormat.Json,
   UriTemplate = "ChangePassword")]
LoginInformations ChangePassword(LoginInformations loginInformations);

[DataContract]
public class LoginInformations
{
    [DataMember]
    public string UserName { set; get; }
    [DataMember]
    public string Password { set; get; }
}

    public LoginInformations ChangePassword(LoginInformations loginInformations)
    {
        try
        {
            loginInformations.Password = "654321";

            return loginInformations;
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }
