如果函数GetTest返回值,一切正常,否则错误。我该如何妥善处理空洞的承诺?我试过,但我得到:如何处理空承诺
无法加载资源:服务器500(内部服务器错误)的状态回应
getTest = function (testId)
{
var promise = $http(
{
method: 'POST',
url: self.baseUrl + 'Test/getTest',
contentType: 'application/json',
data: {
testId: testId
}
});
return promise;
}
[HttpPost]
public ActionResult getTest(string testId)
{
JsonResult jsonResult = new JsonResult();
try
{
Test model = new Test();
string returnValue = model.GetTest(Convert.ToInt32(testId));
if(!string.IsNullOrEmpty(returnValue))
{
jsonResult.Data = returnValue;
Response.StatusCode = 200;
return jsonResult;
}
else
{
Response.StatusCode = 500;
return Content("NoResult");
}
}
catch (Exception ex)
{
return jsonResult;
}
}
你是什么意思“空承诺”。您的状态码为500(“服务器错误”),将被视为错误。你问你如何处理错误? – JLRishe
