DeleteAsync（）未在MVC控制器中访问Web API删除 [英] DeleteAsync() is not Hitting the Web API Delete in MVC Controller

问题描述

[HttpPost, ActionName("DeleteEmp")]
public async Task<ActionResult> DeleteEmp(int Id)
{
   using (HttpClient client = new HttpClient())
   {
string Url = "http://localhost:14316/api/employee";
       var uri = new Uri(string.Format(Url, Id));
       var response = client.DeleteAsync(uri).Result;
       if (response.IsSuccessStatusCode)
       {
          .......
       }              
       return View("GetEmployee", JsonConvert.DeserializeObject<IEnumerable<Employee>>(result));

   }
}

推荐答案

检查以下两行：

Check these two lines:

string Url = "http://localhost:14316/api/employee";
var uri = new Uri(string.Format(Url, Id));

你错过了什么吗？ Id 有什么影响？您的api请求不包含任何 Id 。因此，我认为它没有找到任何匹配的api签名。



此外，异步函数需要await关键字。

Are you missing something? What effect does the Id have here? Your api request does not contain any Id. So, I assume it is therefore not finding any matching api signature.

Also, async function needs await keyword.

I认为这里的问题是await关键字不与async一起使用。请更改行

I think the problem here is the await keyword is not used with async. Please change line

var response = client.DeleteAsync(uri).Result;

to

to

var response = await client.DeleteAsync(uri).Result;

当使用异步调用时，我们应该使用等待关键字

As asynchronous calls are used, we should use await keyword
