将JSON字符串加载到HttpRequestMessage [英] Load JSON string to HttpRequestMessage

问题描述

我正在为我的WebAPI Web服务编写一些测试，但无法在测试中弄清楚如何将JSON发送到我的服务方法.

I'm writing some tests for my WebAPI web service and cannot figure out how to send JSON to my service method in the test.

ScheduleRequest sr = new ScheduleRequest();
sr.Months = null;
sr.States = null;
sr.Zip = null;
sr.Miles = null;
sr.PCodes = null;
sr.PageStart = 1;
sr.PageLimit = 10;

HttpRequestMessage m = new HttpRequestMessage();
string sr_ = JsonConvert.SerializeObject(sr);

// How do I load it into the HttpRequestMessage???
// m.Content. = sr_;
var controller = new ShoppingCartController();

// Call the controlelr method and test if the return data is correct.
EventSyncResponse res = (EventSyncResponse)controller.CourseSchedule(m);

我也正确地做到了吗?

控制器代码:

public object CourseSchedule(ScheduleRequest request)
{
    try
    {
        var result = cart.GetCourseSchedule(request);
        return Ok(result);
    } 
    catch (Exception ex)
    {
        if (ex.Message.StartsWith(@"ORA-20001"))
        {
            return Ok(new ParticipantResponse { FirstName = "No record found" });
        }
        throw ex;
    }
}

推荐答案

[TestClass]
public class ShoppingCartControllerTests {
    [TestMethod]
    public void TestCourseSchedule() {
        //Arrange
        var sr = new ScheduleRequest();
        sr.Months = null;
        sr.States = null;
        sr.Zip = null;
        sr.Miles = null;
        sr.PCodes = null;
        sr.PageStart = 1;
        sr.PageLimit = 10;

        var json = JsonConvert.SerializeObject(sr);
        //construct content to send
        var content = new System.Net.Http.StringContent(json, Encoding.UTF8, "application/json");
        var request = new HttpRequestMessage {
            RequestUri = new Uri("http://localhost/api/shoppingcart"),
            Content = content
        };

        var controller = new ShoppingCartController();
        //Set a fake request. If your controller creates responses you will need this
        controller.Request = request;
        //Act
        // Call the controller method and test if the return data is correct.
        var response = controller.CourseSchedule(request) as OkNegotiatedContentResult<List<EventSyn‌​cResponse>> ;

        //Assert
        //...other asserts
    }
}

但是我觉得您的Action实际上应该在您的控制器中进行重构

But I get the impression that your Action should actually be refactored like this in your controller

public class ShoppingCartController : ApiController {

    public IHttpActionResult CourseSchedule(ScheduleRequest model) { ... }

}

这意味着应该将孤立的单元测试重构为...

which would mean that your isolated unit test should be refactored to...

[TestClass]
public class ShoppingCartControllerTests {
    [TestMethod]
    public void TestCourseSchedule() {
        //Arrange
        var sr = new ScheduleRequest();
        sr.Months = null;
        sr.States = null;
        sr.Zip = null;
        sr.Miles = null;
        sr.PCodes = null;
        sr.PageStart = 1;
        sr.PageLimit = 10;

       var controller = new ShoppingCartController();
        //Set a fake request. If your controller creates responses you will need this
        controller.Request = new HttpRequestMessage {
            RequestUri = new Uri("http://localhost/api/shoppingcart"),
        };
        //Act
        // Call the controller method and test if the return data is correct.
        var response = controller.CourseSchedule(sr) as OkNegotiatedContentResult<List<EventSyn‌​cResponse>> ;;

        //Assert
        //...
    }
}
