我有一个从其他服务获取数据的API。以下代码适用于本地IIS:
if (model.Phone[0] != '+')
{
model.Phone = "+" + model.Phone;
}
string data = Newtonsoft.Json.JsonConvert.SerializeObject(new { ID = Guid.NewGuid(), Phone = model.Phone});
if (!string.IsNullOrEmpty(model.Email))
{
data = Newtonsoft.Json.JsonConvert.SerializeObject(new { ID = Guid.NewGuid(), Phone = model.Phone, Email = model.Email });
}
logger.Debug("GetDataFromSupplier before try");
try
{
WebRequestHandler handler = new WebRequestHandler();
X509Certificate2 certificate = GetMyX509Certificate();
ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
handler.ClientCertificates.Add(certificate);
HttpClient client = new HttpClient(handler);
var content = new StringContent(data, Encoding.UTF8, "application/json");
var request = client.PostAsync(API_URL, content);
var result = request.Result;
return result;
} catch (Exception ex)
{
logger.Debug($"GetDataFromSupplier in catch: {ex.Message}");
var message = new HttpResponseMessage(HttpStatusCode.BadRequest);
message.Content = new StringContent(ex.Message);
return message;
}
但是在我将此代码部署到Azure之后,会话中断了这行代码:
WebRequestHandler handler = new WebRequestHandler();
客户端应用程序获取502 HTTP错误。我试图增加网络服务器的RAM。捕获块甚至没有运行。什么可能导致这个问题?
答案 0 :(得分:0)
查看WebRequestHandler https://msdn.microsoft.com/en-us/library/system.net.http.webrequesthandler(v=vs.110).aspx的文档,它可能不是此处使用的最佳组件。
也许,尝试使用HttpClient。 https://msdn.microsoft.com/en-us/library/system.net.http.httpclient(v=vs.110).aspx因为,WebRequestHandler更适用于桌面应用程序。
由于您提到了IIS,我猜您没有构建桌面应用程序。
