Question

我刚刚构建了我的第一个ASP.NET Web API。我现在正在尝试将一个对象发送到我的API，但不知道该怎么做。

到目前为止，这是我的代码：

Employee employee = new Employee();
employee.Id = 1234;
employee.FirstName = "John";
employee.LastName = "Smith";

using (var client = new HttpClient())
{
   client.BaseAddress = new Uri("http://myapi.mydomain.com");
   client.DefaultRequestHeaders.Accept.Clear();
   client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
   client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", token.AccessToken);

   **// How do I send my employee object to the API?**
   HttpResponseMessage response = await client.GetAsync("api/mycontroller/myaction");
   if (response.IsSuccessStatusCode)
   {
      var someObject = await response.Content.ReadAsAsync<myObjectType>();
   }
}

您需要做的是对API端点执行POST并将您的员工对象序列化为json对象，如下所示：

var gizmo = new Product() { Name = "Gizmo", Price = 100, Category = "Widget" };
response = await client.PostAsJsonAsync("api/products", gizmo);
if (response.IsSuccessStatusCode)
{
    // Get the URI of the created resource.
    Uri gizmoUrl = response.Headers.Location;
}

目前您的现有代码只是执行GET请求。

HttpResponseMessage response = await client.GetAsync("api/mycontroller/myaction");

我强烈建议您take a look at this article明确强调如何通过C＃调用Web API端点。

我希望这会有所帮助。
