我正在使用他们的hosted page integration美元与替代支付进行整合.他们的C#SDK目前还没有这种集成,但正如您所见,它非常简单,我创建了一个小类来发送post请求并获得JSON响应.
我测试了我在PostMan和cURL上发送的json对象,这两种方法都有效,还有身份验证头,所以我认为它们不是问题所在.下面是我的类的构造函数:
public AlternativePaymentsCli(string apiSecretKey)
{
this._apiSecretKey = apiSecretKey;
_httpClient = new HttpClient();
_httpClient.DefaultRequestHeaders.Accept
.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var authInfo = _apiSecretKey;
authInfo = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:", _apiSecretKey)));
// The two line below because I saw in an answer on stackoverflow.
_httpClient.DefaultRequestHeaders.Add("Connection", "Keep-Alive");
_httpClient.DefaultRequestHeaders.Add("Keep-Alive", "3600");
_httpClient.DefaultRequestHeaders.UserAgent.ParseAdd("Anything.com custom client v1.0");
_httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", authInfo);
}
以及我发布数据的方法:
public string CreateHostedPageTransaction(HostedPageRequest req)
{
var settings = new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore };
// I send this same json content on PostMan and it works. The json is not the problem
var content = new StringContent(JsonConvert.SerializeObject(req, settings), Encoding.UTF8, "application/json");
var response = _httpClient.PostAsync(this._baseUrl + "/transactions/hosted", content).Result;
var responseText = response.Content.ReadAsStringAsync().GetAwaiter().GetResult();
if (response.IsSuccessStatusCode)
return responseText;
return "";
}
然后我得到了这个错误:An existing connection was forcibly closed by the remote host
,在PostAsync线上.以下是错误详细信息:
[SocketException (0x2746): An existing connection was forcibly closed by the remote host]
System.Net.Sockets.Socket.EndReceive(IAsyncResult asyncResult) +8192811
System.Net.Sockets.NetworkStream.EndRead(IAsyncResult asyncResult) +47
[IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.]
System.Net.TlsStream.EndWrite(IAsyncResult asyncResult) +294
System.Net.ConnectStream.WriteHeadersCallback(IAsyncResult ar) +149
[WebException: The underlying connection was closed: An unexpected error occurred on a send.]
System.Net.HttpWebRequest.EndGetRequestStream(IAsyncResult asyncResult, TransportContext& context) +324
System.Net.Http.HttpClientHandler.GetRequestStreamCallback(IAsyncResult ar) +137
[HttpRequestException: An error occurred while sending the request.]
我使用的是C#4.5,ASP.NET MVC.我一直在阅读同样错误的答案,但到目前为止都没有解决我的问题.我在这段代码中遗漏了什么?
谢谢你的帮助
