MVC Post请求始终返回IIS错误500，但适用于邮递员
MVC Post请求始终返回IIS错误500，但适用于邮递员
提问于 2021-11-03 12:20:10
我正在尝试向IIS中承载的webapi应用程序发送post请求。对于post请求，我总是得到错误500，但get请求工作正常。下面是我的代码
型号：
public class LineModel
{
[Key]
public string ID { get; set; }
public string No { get; set; }
public string Name { get; set; }
public string Title { get; set; }
public string Code1 { get; set; }
public string Code2 { get; set; }
public DateTime Date { get; set; }
public string Type { get; set; }
public string Remarks { get; set; }
public string Status { get; set; }
public List<SubLine> SubLines { get; set; }
}显示表单的Ajax代码：
$(function () {
$(".surveyType").click(function () {
var surveyType = $(this).attr("data-bind");
$.ajax({
url: "/Aella/Create/",
data: { "surveyCode": surveyType },
success: function (data) {
console.log(data);
$('#Question').html(data);
};
}
});
});Ajax调用post请求：
$('body').on('click','#submit-request', function () {
var formData = $("#create-request").serialize();
console.log(formData);
$.ajax({
url: "/Aella/Create/",
data: formData,
type: "POST",
dataType: 'json',
contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
success: function (data)
{
console.log(data);
}
});
});Get请求：
[HttpGet]
public ActionResult Create(string surveyCode)
{
questions = GetSurveyQuestions(surveyCode);
LineModel model = new LineModel
{
SubLines = questions.Select(a => new SubLine()
{
Question = a.questionField,
Code = a.codeField,
Type = a.question_TypeField.ToString(),
Survey_Type = a.survey_TypeField,
Response = "",
Remark = ""
}).ToList(),
Type = surveyCode,
Date = DateTime.Now
};
return View(model);
}Post方法：
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Create(LineModel lineModel)
{
if(ModelState.IsValid)
{
lineModel.Status = "Open";
foreach(var item in lineModel.SubLines)
{
if(item.Type == "Remark")
{
item.Remark = item.Response;
item.Response = "";
}
}
HttpClient client = new HttpClient
{
BaseAddress = new Uri(ConfigurationManager.AppSettings["lineModelLink"].ToString())
};
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
jsonContent = JsonConvert.SerializeObject(lineModel);
contentString = new StringContent(jsonContent, Encoding.UTF8, "application/json");
contentString.Headers.ContentType = new MediaTypeHeaderValue("application/json");
HttpResponseMessage response = new HttpResponseMessage();
try
{
response = await client.PostAsync(ConfigurationManager.AppSettings["lineModelLink"].ToString(), contentString);
}
catch(HttpRequestException ex)
{
ErrorController.LogError(ex);
ViewBag.Response = JsonConvert.DeserializeObject(responseStr);
if (lineModel.lineModelLines.Count > 0)
{
ViewBag.IsQuestionAvailable = true;
}
return View(lineModel);
}
[...]
}

您的post ajax请求有一个包
url: "/Survey/CreateSurvey/",但您的操作是创建。你必须调整动作的名称。
似乎Get操作应该在同一个控制器中，但它也有一个奇怪的url。
url: "/Aella/Create/",修复这些错误后，尝试一步一步地调试应用程序的其他部分。因为我可以在你的局部视图中看到很多我以前从未见过的html助手，我不确定它们是否生成了可以提交的正确的mvc html。因此，我建议首先对部分视图进行注释，并尝试将工作视图作为主视图。在此之后，您可以继续使用局部视图逐行添加。

关于代码的一切都很好，我观察到服务器上的证书已经过期，因此出现错误。谢谢大家
