我正在尝试详细描述我的问题。我们的目标是将对象发送到处理的wcf服务,并用另一个对象进行响应。如果我们发送1000、2000对象,则结果成功。但是,当我们增加对象的大小(如10.000、20.000)时,服务器等待1-1.30分钟,然后响应504网关错误。 首先,在客户端,我们上传文件,然后将其读取到服务器端。我们初始化读取数据的对象,然后将该对象发送给服务。我的控制器如下:
public ActionResult SaleNotification(NOTIFICATION_OBJECT notificationItem, HttpPostedFileBase files)
{
if (files != null)
{
List<NOTIFICATION_ITEM_OBJECT> fileItems = new List<NOTIFICATION_ITEM_OBJECT>();
using (var package = new StreamReader(files.InputStream))
{
package.ReadLine();
while (!package.EndOfStream)
{
var values = package.ReadLine().Split(';');
if (values[0] != "" && values[1] != "" && values[2] != "" && values[3] != "")
{
fileItems.Add(new NOTIFICATION_ITEM_OBJECT
{
GT = values[0],
SN = values[1].ToUpper(),
BN = values[2].ToUpper(),
XD = values[3]
});
}
}
}
notificationItem.NOTIFICATION_ITEMS.AddRange(fileItems);
}
var res = _serviceRepository.SendNotification(Security.Decrypt(SERVICE_PASS_ENCRYPT, true), notificationItem);
return PartialView("PartialResult", res);
}
发送通知到服务部分,我试图一次发送整个对象,也许那部分我的方法是错误的。这是我的代码:
public NOTIFICATION_RESULT_OBJECT SendNotification( string password, NOTIFICATION_OBJECT notification)
{
var res = new NOTIFICATION_RESULT_OBJECT();
try
{
var client = new serviceClient();
if (client.ClientCredentials != null)
{
client.ClientCredentials.UserName.Password = password;
}
using (new OperationContextScope(client.InnerChannel))
{
#region header
var requestMessage = new HttpRequestMessageProperty();
OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = requestMessage;
#endregion
//Some codes service request initialize
ServicePointManager.ServerCertificateValidationCallback = delegate (object s, System.Security.Cryptography.X509Certificates.X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };
var response = client.notify(serviceRequest);
res.NOTIFICATION_ID = response.NOTIFICATIONID;
foreach (var item in response)
res.PRODUCT_RESULT_LIST.Add(new PRODUCT_RESULT()
{
GT = item.GT,
RC = item.RC,
SN = item.SN,
BN = item.BN,
XD = item.XD.ToString("dd/MM/yyyy", new CultureInfo("tr-TR")),
});
return res;
}
}
catch (Exception ex)
{
Log4NetFunction.InsertLog(ex);
return res;
}
}
}
我的绑定上有一个关于maxReceivedMessageSize,sendTimeout,receivedTimeout等的配置。这是我的绑定之一的示例:
<binding name="serviceBinding" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" openTimeout="00:10:00"
closeTimeout="00:10:00" sendTimeout="00:15:00" receiveTimeout="00:10:00">
<security mode="Transport">
<transport clientCredentialType="Basic" proxyCredentialType="Basic" realm="" />
<message clientCredentialType="Certificate" algorithmSuite="Default" />
</security>
</binding>
在调试中,我找不到任何错误,它在本地成功发送了20000个对象,或者在服务器上没有有关此错误的日志。所以我找不到任何解决方案。我怎么解决这个问题?我的方法不对吗?
答案 0 :(得分:0)
也许您的服务拒绝将具有这么多数据成员的数据序列化。
请尝试设置绑定的readerQuotas属性。
<binding allowCookies="false" maxBufferPoolSize="2147483647" maxBufferSize="2147483647"
maxReceivedMessageSize="2147483647" openTimeout="00:10:00"
closeTimeout="00:10:00" sendTimeout="00:15:00" receiveTimeout="00:10:00" >
<readerQuotas maxArrayLength="2147483647" maxNameTableCharCount="2147483647"
maxStringContentLength="2147483647" maxDepth="2147483647"
maxBytesPerRead="2147483647" />
<security mode="None" />
</binding>
