Question

我正在使用ASP.NET MVC应用程序进行Web API调用（GET请求）来获取JSON数据。我能够检索数据但是当它返回时，JSON数据中现在有反斜杠。

C＃Controller：

        [HttpGet]
        [Route("company-info/companyinfogetapidata")]
        public ActionResult CompanyInfoGetApiData(string name, int CompanyCode, string city, string state, int zip)
        {

            HttpClient client = new HttpClient();

            client.BaseAddress = new Uri("URL_BASE");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            var request = client.GetAsync("URL_PATH");                        

            return Json(request.Result.Content.ReadAsStringAsync().Result, JsonRequestBehavior.AllowGet);            

        }

当我使用Stackify Prefix查看从服务器返回的响应时，我得到的JSON数据如下所示：

"{\n\"results\":[\n{\n\t\"name\":\"Company  XYZ\",\n\t\"providerName\": \"Company Provider Info\",

它应该是这样的：

{"results":[{"name":"Company  XYZ", "providerName": "Company Provider Info",

最初我只是使用反斜杠，但我想要删除它们的原因是因为当我尝试在AJAX Success函数中使用此返回的数据时，JSON数据属性未被正确读取。当我尝试从foreach循环中访问Cannot read property '0' of undefined时，出现name错误。

AJAX代码：

         $.ajax({
                    type: "GET",
                    url:"../companyfindergetapidata",
                    dataType: "json",
                    data: {DATA_HERE},
                    error:function(e){alert("nope"+e);},
                    success: function (xhr_request) {                        

                        var fetched_data = xhr_request["results"];

                        var i;
                        var iLength = xhr_request.length;

                        for (i = 0; i < iLength; i++) {

             // THIS IS WHERE I GET AN ERROR "Cannot read property '0' of undefined

                            $("#CompanyFinderResultsContainer").append("<p>Name:&nbsp;" + fetched_data[i].name + "</p>");
                        }


                    }
                });

非常感谢任何帮助！

有些编辑，这更接近原始代码。注意添加使用;

using Newtonsoft.Json.Linq;


[HttpGet]
[Route("company-info/companyinfogetapidata")]
[AllowAnonymous]
public ActionResult CompanyInfoGetApiData(string name, int CompanyCode, string city, string state, int zip)
    {

        HttpClient client = new HttpClient();

        client.BaseAddress = new Uri("URL_BASE");
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

        var request = client.GetAsync("URL_PATH");                
        var json = request.Result.Content.ReadAsStringAsync().Result;
        json = JToken.Parse(json).ToString();

        return Json(json, JsonRequestBehavior.AllowGet);         
    }

无法显示来自Web API调用的Fetched JSON数据，因为反斜杠是响应
