如何在异步控制器中验证模型状态
|
我正在尝试使用异步控制器，但无法弄清楚如何验证用户输入。
以下是控制器中定义的两个异步方法。我应该在SearchAsync方法还是SearchCompleted方法中检查ModelState.IsValid。如果使用SearchAsync，则由于其返回类型为空，如何返回视图结果。如果使用SearchCompleted，则该方法将如何知道searchForm参数。
[HttpPost]
[ValidateAntiForgeryToken]
public void SearchAsync(BusinessSearchForm searchForm)
{
AsyncManager.OutstandingOperations.Increment();
new Thread(() =>
{
var suggestions = _searchSvc.GetSuggestions(searchForm.BusinessName, searchForm.StreetAddress, searchForm.City, searchForm.PostalCode);
AsyncManager.Parameters[\"suggestions\"] = suggestions;
AsyncManager.OutstandingOperations.Decrement();
}).Start();
}
public ActionResult SearchCompleted(IEnumerable<BusinessSuggestionBase> suggestions)
{
return View(suggestions);
}
没有找到相关结果

[HttpPost] [ValidateAntiForgeryToken] public void SearchAsync(BusinessSearchForm searchForm) { if (ModelState.IsValid) { AsyncManager.OutstandingOperations.Increment(); new Thread(() => { if (ModelState.IsValid) { var suggestions = _searchBusinessSvc.GetSuggestions(searchForm.BusinessName, searchForm.StreetAddress, searchForm.City, searchForm.PostalCode); AsyncManager.Parameters[\"suggestions\"] = suggestions; } AsyncManager.Parameters[\"searchForm\"] = searchForm; AsyncManager.OutstandingOperations.Decrement(); }).Start(); } } public ActionResult SearchCompleted(BusinessSearchForm searchForm,IEnumerable<BusinessSuggestionBase> suggestions) { if (ModelState.IsValid) { TempData[\"suggestions\"] = suggestions; return RedirectToAction(\"SearchResult\"); } return View(searchForm); }蓄荣糖些
在Async方法中if(AsyncManager.Parameters[\'ModelIsValid\'] == false) { ... }
