asp.net-mvc - 尝试读取 Web API 调用的响应

Question

我尝试通过 Web API 调用读取我的员工列表，但出现错误。

using (var client = new HttpClient())
{
   client.BaseAddress = new Uri("http://myApiUrl");
   client.DefaultRequestHeaders.Accept.Clear();
   client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

   HttpResponseMessage response = await client.GetAsync("api/hr/employees");
   if (response.IsSuccessStatusCode)
   {
      List<Employee> employees = response.Content.ReadAsAsync(IEnumerable<Employee>).Result;
   }
}

我当前收到的错误是: System.Net.Http.HttpContent 不包含 ReadAsAsync 的定义...

我做错了什么？

Answer 1

ReadAsAsync 不是 HttpClient 类上的方法。如果你想读取数据并将其转换为一个对象，你可以使用:

HttpResponseMessage response = await client.GetAsync("api/hr/employees");
if (response.IsSuccessStatusCode)
{
    var result= await response.Content.ReadAsStringAsync();
    List<Employee> employees = JsonConvert.DeserializeObject<Employee>(result);
}
