从Asp.net WEBAPI显式返回JSON字符串？

从Asp.net WEBAPI显式返回JSON字符串？

有几种选择。最简单的方法是让您的方法返回

HttpResponseMessage

，并

StringContent

根据您的字符串使用来创建该响应，类似于下面的代码：

public HttpResponseMessage Get(){    string yourJson = GetJsonFromSomewhere();    var response = this.Request.CreateResponse(HttpStatusCode.OK);    response.Content = new StringContent(yourJson, Encoding.UTF8, "application/json");    return response;}

并检查null或空的JSON字符串

public HttpResponseMessage Get(){    string yourJson = GetJsonFromSomewhere();    if (!string.IsNullOrEmpty(yourJson))    {        var response = this.Request.CreateResponse(HttpStatusCode.OK);        response.Content = new StringContent(yourJson, Encoding.UTF8, "application/json");        return response;    }    throw new HttpResponseException(HttpStatusCode.NotFound);}
