我是在 C# 中编写泛型方法的新手，我正在尝试SendAsync在我的 C# 项目中创建一个泛型方法。代码如下。

HttpClientHelper.cs

public static async Task<T2t> ExecuteRequest<T1,T2>(T2 request, string url)
{
    Uri requestUri = new Uri(url);
    string payload = JsonConvert.SerializeObject(request);
    HttpContent httpContent = new StringContent(payload, "application/json");

    HttpRequestMessage requestMessage = new HttpRequestMessage
    {
        Method = HttpMethod.Post,
        RequestUri = requestUri,
        Content = httpContent
    };

    return await SendUriAsync<T2>(requestMessage);
}

public static async Task<T> SendUriAsync<T>(HttpRequestMessage requestMessage)
{
   
    string clint_id = "1234";
    
      var clineCred = Encoding.UTF8.GetBytes($"{client_id}");
        
        using(var result = await client.SendAsync(requestMessage))
        {
            result.EnsureSuccessStatusCode();
            var response = await result.Content.ReadAsStringAsync();
            
            if(result.IsSuccessStatusCode && response != null)
            {
                return JsonConvert.DeserializeObject<T>(response);
            }
            else
            {
                return null;
            }
        }        
 
}

这是调用这些方法的控制器类：

CarSalesController.cs

string thirdpartyUrl = "someurl";
var responseObject = await HttpClientHelper.ExecuteRequest<CarObject, string>(requestObject, thirdpartyUrl);

我在HttpClientHelper课堂上遇到错误。错误是：

ResponseStatusCode 不表示成功。状态码：401 - 未经授权

但是当我使用邮递员时，相同的 API 效果很好。他是卷曲

curl --location --request GET 'someurl'
--header 'client_id:1234'
--header '授权：基本 asdf'
--header 'Content-Type: application/json'
--data-raw '{ "data1" :"somedata1", "data2":"somedata2" }'

我的代码可能有什么问题？

问题可能出在DeserializeObject. 尝试使用：

response.Content.ReadAsStringAsync()

这不是你想要做的吗？

public async Task<TOut> ExecuteRequestAsync<TIn, TOut>( TIn request, string url )
{
    var requestUri = new Uri( url );
    var payload = JsonConvert.SerializeObject( request );
    var httpContent = new StringContent( payload, Encoding.UTF8, "application/json" );
    var requestMessage = new HttpRequestMessage()
    {
        Method = HttpMethod.Post,
        RequestUri = requestUri,
        Content = httpContent
    };
    return await SendUriAsync<TOut>( requestMessage );
}

public static async Task<T> SendUriAsync<T>( HttpRequestMessage requestMessage )
{
    using (var client = CreateClient( 1234 ))
    {
        var result = await client.SendAsync( requestMessage );
        result.EnsureSuccessStatusCode();
        var response = await result.Content.ReadAsStringAsync();
        return JsonConvert.DeserializeObject<T>( response );
    }
}

private static HttpClient CreateClient(int clientId)
{
    var clientCred = Encoding.UTF8.GetBytes( clientId.ToString() );
    var auth = Convert.ToBase64String( clientCred );
    var client = new HttpClient();
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue( "Basic", auth );
    client.DefaultRequestHeaders.Add( "client_id", "1234" );
    return client;
}
