c# - svcutil.exe 或测试 wcf 服务 JSON 输出？

Question

这篇文章是我最后一篇 question 的文章(以为我会开始一个新问题)。

我正在尝试创建和测试一个输出 JSON 的简单(对你来说很简单，对我来说很简单)WCF Web 服务。我相信(在帮助下)应用程序没问题，但我需要对其进行测试，但我不确定如何进行测试。

我将在下面附上我的代码，但这是发生了什么，如果我运行应用程序，它会加载 http://localhost:52002/如果在我的 .svc 中运行应用程序，我会收到 ASP.NET 页面的欢迎，它会加载 http://localhost:52002/MyTestService.svc我得到了页面:

You have created a service.

To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:

svcutil.exe http://localhost:52002/MyTestService.svc?wsdl

有人告诉我可以 http://localhost:52002/MyTestService.svc/GetResults查看 JSON 输出(参见下面的代码)但我得到的是:

The webpage cannot be found

任何建议都很好，我很抱歉现在对这一切有点陌生，请你把事情拼写得比平时多一点，哈哈

下面是我的代码和坦克非常多

Person.cs

[DataContract]
public class Person
{
    [DataMember]
    public string FirstName { get; set; }

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

    [DataMember]
    public int Age { get; set; }

    public Person(string firstName, string lastName, int age)
    {
        this.FirstName = firstName;
        this.LastName = lastName;
        this.Age = age;
    }
}

MyTestServices.svc.cs

[ServiceContract(Namespace = "")]
    [AspNetCompatibilityRequirements(RequirementsMode =  `AspNetCompatibilityRequirementsMode.Allowed)]`
    public class TestService
    {
    [OperationContract]
    [WebGet(ResponseFormat = WebMessageFormat.Json)]

    public List<Person> GetResults()
    {
        List<Person> results = new List<Person>();
        results.Add(new Person("Peyton", "Manning", 35));
        results.Add(new Person("Drew", "Brees", 31));
        results.Add(new Person("Tony", "Romo", 29));

        return results;
    }

我总是使用 fiddler调试请求。使用新的 WCF Web Api，您可以将客户端的接受 header 设置为 application/JSON，响应将被格式化为 JSON。
