使用 Web Api 作为 Http Post

Question

有人可以帮我如何将 long 类型的数组发布到 WebApi。

我想我必须使用来自 HttpClient 的 PostAsync，但我不确定如何将数组放入 HttpContent。

这是我的控制器。

 [HttpPost]
 [Authorize]
 public void UpdateBatchesToReadyToShip(long[] batchIds)
 {
            // process request
  }

这就是我尝试使用 API 的方式

var buffer = Encoding.ASCII.GetBytes("username:password");
var authHeader = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(buffer));
client.DefaultRequestHeaders.Authorization = authHeader;
var arr = new long[3];
arr[0] = 10;
arr[1] = 12;
arr[2] = 13;
HttpContent content = new StringContent(string.Join(",", from i in arr select i.ToString()));
var task = client.PostAsync("https://<uri>/api/orderprocessing/UpdateBatchesToReadyToShip",content:content);
if (task.Result.StatusCode == HttpStatusCode.Unauthorized)
{
Console.WriteLine("wrong credentials");
}
else
{
//task.Result.EnsureSuccessStatusCode();
HttpResponseMessage message = task.Result;
if (message.IsSuccessStatusCode)
{
var details = message.Content.ReadAsStringAsync().Result;
Console.Write(details);
}
}

我遇到了这个异常

{StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
  Pragma: no-cache
  Cache-Control: no-cache

您可以使用 ObjectContent，而不是使用 StringContent：

var content = new ObjectContent<long[]>(arr, new JsonMediaTypeFormatter());

var task = client.PostAsync(
    "https://<uri>/api/orderprocessing/UpdateBatchesToReadyToShip",
    content:content);
