http状态代码200返回预期结果。但是，当状态为BadRequest或未经授权时，我的C＃webapi 1返回text / html

Question

public HttpResponseMessage Get()
    {
        sessionResponse.message = "Not permitted";
        sessionResponse.code = statusCode.Unauthorized;

        HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.Unauthorized, sessionResponse);
        return response;
    }

This is giving me total html page: 这给了我整个html页面：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>401 - Unauthorized: Access is denied due to invalid credentials.</title></head>
<body>
<div id="header"><h1>Server Error</h1></div>
<div id="content">
<div class="content-container"><fieldset>
<h2>401 - Unauthorized: Access is denied due to invalid credentials.</h2>
<h3>You do not have permission to view this directory or page using the credentials that you supplied.</h3>
 </fieldset></div>
</div>
</body>
</html>

But when I am running this code: 但是当我运行这段代码时：

public HttpResponseMessage Get()
    {
        sessionResponse.message = "Not permitted";
        sessionResponse.code = statusCode.Unauthorized;

        HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK, sessionResponse);
        return response;
    }

I am getting desired JSON: { message: "Not permitted", code:"401" } 我正在获取所需的JSON：{消息：“不允许”，代码：“ 401”}

So, I am facing the problem when response is not HTTPSTATUSCODE.OK, I am not getting JSON. 所以，当响应不是HTTPSTATUSCODE.OK时，我遇到了问题，我没有得到JSON。 If status code is Bad request or Unauthorized, I am getting text/html. 如果状态代码是“错误请求”或“未授权”，则我正在获取text / html。 What to do with it ? 怎么办呢？ I have added JSON formatter in apiconfig file, but no luck. 我在apiconfig文件中添加了JSON格式化程序，但是没有运气。

您可以使用Request.CreateResponse重载，该重载通过string接受MediaTypeFormatter类型或媒体类型，以明确声明您要使用的格式化程序：

return Request.CreateResponse(HttpStatusCode.Unauthorized, sessionResponse, "application/json");
