这两种方式都是以HttpResponseMessage的形式返回,
方式一:以字符串的形式
var content = new StringContent("{\"FileName\": \"" + fileName + "\"}"); HttpResponseMessage response = new HttpResponseMessage() { Content = content }; response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
方式二:以对象(这里用的是字典)的方式
var fileNames = new Dictionary<string, string>();
fileNames.Add("FileName", fileName);
var content = new ObjectContent<Dictionary<string, string>>(fileNames, new JsonMediaTypeFormatter(), "application/json");
HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK, content);
