如何让Web Api将Json.net序列化的字符串对象正确地发送回客户端？

I am serializing an IEnumerbale object using JsonConvert.SerializeObject( ); it produces string with quotes and escape character with spaces

我正在使用JsonConvert.SerializeObject()序列化IEnumerbale对象;它生成带引号的字符串和带空格的转义字符

from web Api controller i return that string using code below

来自web Api控制器我使用下面的代码返回该字符串

[HttpGet]
public string GetDegreeCodes(int id)
{
    string result = //output from JsonConvert.SerializeObject( );
    return result;
}

"[{\"DegreeId\":1,\"DegreeName\":\"High School\",\"ImageSrc\":\" http://bootsnipp.com/apple-touch-icon-114x114-pre\",\"Description\":\" Get High School Degree\r\"},{\"DegreeId\":2,\"DegreeName\":\"Associate\",\"ImageSrc\":\" http://bootsnipp.com/apple-touch-icon-114x114-pre\",\"Description\":\" Get Associate Degree\r\"},{\"DegreeId\":3,\"DegreeName\":\"Bachelor\",\"ImageSrc\":\" http://bootsnipp.com/apple-touch-icon-114x114-pre\",\"Description\":\" Get Bachelor Degree\r\"},{\"DegreeId\":4,\"DegreeName\":\"Masters\",\"ImageSrc\":\" http://bootsnipp.com/apple-touch-icon-114x114-pre\",\"Description\":\" Get Master Degree\r\"},{\"DegreeId\":5,\"DegreeName\":\"Doctrate\",\"ImageSrc\":\" http://bootsnipp.com/apple-touch-icon-114x114-pre\",\"Description\":\" Get Doctorate Degree\"}]"

“[{\”DegreeId \“:1,\”DegreeName \“:\”High School \“,\”ImageSrc \“:\”http://bootsnipp.com/apple-touch-icon-114x114-pre \ “,”描述\“:\”获得高中学位\ r \“},{\”DegreeId \“:2,\”DegreeName \“:\”Associate \“,\”ImageSrc \“:\”http ://bootsnipp.com/apple-touch-icon-114x114-pre \“,\”描述\“:\”获得副学士学位\ r \“},{\”DegreeId \“:3,\”DegreeName \“ :\“Bachelor \”,“ImageSrc”:\“http://bootsnipp.com/apple-touch-icon-114x114-pre \”,\“Description \”:\“获得学士学位\ r \ n” },{\“DegreeId \”:4,\“DegreeName \”:\“Masters \”,\“ImageSrc \”:\“http://bootsnipp.com/apple-touch-icon-114x114-pre \” ,\“Description \”:\“获取硕士学位\ r \”},{\“DegreeId \”:5,\“DegreeName \”:\“Doctrate \”,\“ImageSrc \”:\“http:/ /bootsnipp.com/apple-touch-icon-114x114-pre \“,\”描述\“:\”获得博士学位\“}]”

This is my ajax and it does not recognize the JSON correctly because of the extra wrapper quotes and escape characters,

这是我的ajax,由于额外的包装引号和转义字符,它无法正确识别JSON,

$.ajax({
        url: "/api/helloservice/getdegreecodes",
        type: "get",
        contentType: "application/text",
        data: { id: 1 }
    }).done(function (data) {
        if (data.length > 0) {

            for (i = 0; i < data.length; i++) {
                viewEduModel.degreeCodes.push(data[i]);
            }

        }
    });

i need to use JsonConvert.SerializeObject since i am caching it as a JSon in my redis cache server using booksleeve that way I do not need to re serialize and read from db every time. how do i avoid web api controller sending Quotes and backslashes? i could simply return IEnumerable and let Web Api do the JSOn serialization but i need to cache it on redis side

我需要使用JsonConvert.SerializeObject,因为我在使用booksleeve的redis缓存服务器中将其作为JSon缓存,这样我每次都不需要重新序列化并从db读取。我如何避免web api控制器发送报价和反斜杠?我可以简单地返回IEnumerable并让Web Api执行JSOn序列化但我需要在redis端缓存它

2 个解决方案

You could something like below:

你可以像下面这样:

[HttpGet]
public HttpResponseMessage GetDegreeCodes(int id)
{
    StringContent sc = new StringContent("Your JSON content from Redis here");
    sc.Headers.ContentType = new MediaTypeHeaderValue("application/json");

    HttpResponseMessage resp = new HttpResponseMessage();
    resp.Content = sc;

    return resp;
}

by using this you can call your webapi through code.

通过使用它,您可以通过代码调用您的webapi。

using (var client = new WebClient()) //WebClient  
{
   string mystring = "";               
  client.Headers.Add("Content-Type:application/json"); //Content-Type  
  client.Headers.Add("Accept:application/json");                      
  var dataa = Encoding.UTF8.GetBytes("{\"Username\":\"sdfsd\"}");                      
  byte[] a = client.UploadData("your API url", "POST",dataa);                        
  myString = Encoding.UTF8.GetString(a);
  
  }
