我要努力弄清楚如何将POST参数传递给ASPNET CORE 2.0中的Web API方法。
我有一个C#客户端应用程序和一个C#服务器应用程序。
它总是为空。发生了什么事?
客户代码:
private static async Task SendCustomObject()
{
var controllerName = "BasicApi";
var basicClientApi = string.Format("http://localhost:5100/api/{0}", controllerName);
using (var httpClient = new HttpClient()){
var packetData = new TestPacket();
var jsonObj = new { json = packetData };
JObject jobject = JObject.FromObject(packetData);
var json = JsonConvert.SerializeObject(jobject);
var content = new StringContent(json, Encoding.UTF8, "application/json");
content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
// This doesn't help:
//httpClient.DefaultRequestHeaders.Accept.Clear();
//httpClient.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
var response = await httpClient.PostAsync(basicClientApi, content);
if (!response.IsSuccessStatusCode)
{
Console.WriteLine(response.StatusCode);
}
else
{
var rawResponse = await response.Content.ReadAsStringAsync();
JObject o = JObject.Parse(rawResponse);
Console.WriteLine(o.ToString());
}
}
}
服务器代码:
namespace myApp.Controllers
{
[Route("api/[controller]")]
public class BasicApiController : Controller
{
[HttpPost]
public JsonResult Post([FromBody] string json) // json is always null!
{
var jsonData = JsonConvert.DeserializeObject<Models.TestPacket>(json);
return Json(new { result = true });
}
}
}

ASP.NET Core默认绑定程序为您反序列化模型,您无需手动进行。具体来说,您不能将update
视为object
。
看看这个简单得多的示例:
