我试图使用ASP.NET Web API返回一个JSON文件(用于测试).

public string[] Get()
{
    string[] text = System.IO.File.ReadAllLines(@"c:\data.json");

    return text;
}

在Fiddler中,它确实显示为Json类型,但是当我在Chrome中调试并查看它出现的对象和各行的数组(左)时.正确的图像是我使用它时对象应该是什么样子.

任何人都可以告诉我应该返回什么以正确的格式获得Json结果？

出于某种原因,Request.CreateResponse在VS2012中现在是"红色",当我将鼠标悬停在IDE的使用状态时

无法解析符号'CreateResponse'

这是ApiController类:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Web.Http.Filters;
using GOCApi.Attributes;
using GOCApi.Models;
using GOCApi.Models.Abstract;
using AttributeRouting;
using AttributeRouting.Web.Http;

namespace GOCApi.Controllers
{
    [RoutePrefix("Courses")]
    public class CoursesController : ApiController
    {
        private ICoursesRepository _coursesRepository { get; set; }

        public CoursesController(ICoursesRepository coursesRepository)
        {
            _coursesRepository = coursesRepository;
        }

        [GET("{id}")]
        public HttpResponseMessage Get(int id)
        {
            var course = _coursesRepository.GetSingle(id);
            if (course == null)
            return Request.CreateResponse(HttpStatusCode.NotFound, "Invalid ID");
            return Request.CreateResponse(HttpStatusCode.OK, course);
        }
    }
}

当然,代码确实可以编译和工作,只是看到屏幕上的所有"红色"真的很烦人.此外,当我输入时,intellisense现在不起作用Request.CreateResponse …

是否可以使用返回值和异常更改此代码:

public Foo Bar(Bar b)
{
   if(b.Success)
   {
      return b;
   }
   else
   {
      throw n.Exception;
   }
}

对此,它为成功和失败抛出了单独的例外

public Foo Bar(Bar b)
{
   throw b.Success ? new BarException(b) : new FooException();
}

try
{
   Bar(b)
}
catch(BarException bex)
{
   return ex.Bar;
}
catch(FooException fex)
{
   Console.WriteLine(fex.Message);
}

如何从WebAPI方法返回HTTP 403？我试过用HttpStatusCode.Forbidden抛出一个HttpResponseException,我试过了

return request.CreateErrorResponse(HttpStatusCode.Forbidden, pEx);

两者都不奏效.两者总是返回HTTP 200.我错过了什么？它必须是简单的东西,但我没有看到它.

我是webapi的新手,并开发了一个小的webapi,它有一些动作并返回我的自定义类,名为Response.

该Response班

public class Response
{
    bool IsSuccess=false;
    string Message;
    object ResponseData;

    public Response(bool status, string message, object data)
    {
        IsSuccess = status;
        Message = message;
        ResponseData = data;
    }
}

我的webapi有行动

[RoutePrefix("api/customer")]
public class CustomerController : ApiController
{
    static readonly ICustomerRepository repository = new CustomerRepository();

    [HttpGet, Route("GetAll")]
    public Response GetAllCustomers()
    {
        return new Response(true, "SUCCESS", repository.GetAll());
    }

    [HttpGet, Route("GetByID/{customerID}")]
    public Response GetCustomer(string customerID)
    {
        Customer customer = repository.Get(customerID);
        if (customer == null)
        {
            throw new HttpResponseException(HttpStatusCode.NotFound);
        } …
