我使用 MVC (不是web api),因此控制器继承自Controller,而不是ApiController。
我用 ajax 调用控制器操作( POST ),操作返回 HttpResponseMessage
这是我得到的回应:
{"readyState":4,"responseText":"StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StringContent, Headers:\r\n{\r\n Location: /\r\n Content-Type: application/json; charset=utf-8\r\n}","status":200,"statusText":"OK"}
但是,当ajax接收数据时,它会触发fail方法。
这是ajax函数:
$.ajax({
url: "someurl",
type: "post",
data: data,
dataType: "json",
contentType: "application/json; charset=utf-8"
}).done(function (data) {
alert(data.responseText);
window.location.href = "redirect to some url";
}).fail(function (data) {
alert("error");<-- this one is called even when i set HttpStatusCode.OK
alert(JSON.stringify(data));
}).always(function () {
});
这是一个简化的控制器动作:
[HttpPost]
[AllowAnonymous]
public HttpResponseMessage Index(HttpRequestMessage request, Login model)
//public HttpResponseMessage Index(Login model) // i get the same with any of these 2
{
HttpResponseMessage response = new HttpResponseMessage();
string message = "";
if (something)
{
response.StatusCode = HttpStatusCode.OK;
FormsAuthentication.SetAuthCookie(model.UserName, true);
currentUser.LastLoginDate = DateTime.Now;
currentUser.FailedPasswordAttemptCount = 0;
ModelRepositories.MobileCommerceRepository.SaveChanges();
}
else
{
message = "User does not exist. The user name or password provided is incorrect.";
response.StatusCode = HttpStatusCode.BadRequest;
}
//response = request.CreateResponse(HttpStatusCode.OK);
string json = JsonSerializer.SerializeToString(message);
response.Content = new StringContent(json, Encoding.UTF8, "application/json");
return response;
}
如果我对web api控制器执行相同的ajax调用(内部使用相同的C#代码),则会触发成功。有什么区别?

您不能将HttpResponseMessage与MVC操作一起使用。 Web API和MVC是两个不同的框架,你不能混合和匹配它们。

如果有人还在寻找我的回答。我同意之前的帖子,因为MVC不会返回实际内容。相反,我使用
public async Task<string> GetAjaxCollateralSummary(string id)
{
//your logic
return JsonConvert.SerializeObject(result);
}
and the in my js page I have following code:
$.post(url, { id: '2' })
.success(function (response) {
console.log(response);
var jsondResult = JSON.parse(response);
}
)
.error(function (err) {
console.log("Error while trying to get data from MVC controller ");
console.log(err);
})
