来自网站但不来自控制台应用程序的 Web 服务调用中出现 EndpointNotFoundException

我在网站的 Web 服务调用中收到此 EndpointNotFoundException ，而如果我从控制台应用程序执行此操作，则同样的调用也有效。这是更详细的异常消息：

Could not connect to https://******. TCP error code 10060:
A connection attempt failed because the connected party did not properly
respond after a period of time, or established connection failed because
connected host has failed to respond ***.***.***.***:443.

我已经确认绑定（在 web.config 和 app.config 中）是相同的，所以我不明白为什么会这样在一种情况下有效，在另一种情况下无效。

<basicHttpBinding>
<binding name="ServicePortBinding" closeTimeout="00:01:00" openTimeout="00:01:00"
 receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
 bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
 useDefaultWebProxy="true">
 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
  maxBytesPerRead="4096" maxNameTableCharCount="16384" />
 <security mode="Transport">
  <transport clientCredentialType="None" proxyCredentialType="None"
   realm="" />
  <message clientCredentialType="UserName" algorithmSuite="Default" />
 </security>
</binding>
</basicHttpBinding>

如果您需要更多详细信息，请告诉我。

好的，这是我遗漏的一些可能导致问题的内容。这一切都发生在公司防火墙后面。难道说防火墙阻止它从网站运行，因为它是从现有的“Web 进程”产生的 HTTP 连接？而在控制台应用程序中，它只是一个连接。

I'm getting this EndpointNotFoundException on a webservice call from a website, while the same exact call works if I do it from a console application.
Here's the more detailed exception message:

Could not connect to https://******. TCP error code 10060:
A connection attempt failed because the connected party did not properly
respond after a period of time, or established connection failed because
connected host has failed to respond ***.***.***.***:443.

I've confirmed that the bindings (in web.config and app.config) are the same, so I can't see why it works in one case and not in the other.

<basicHttpBinding>
<binding name="ServicePortBinding" closeTimeout="00:01:00" openTimeout="00:01:00"
 receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
 bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
 maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
 messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
 useDefaultWebProxy="true">
 <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
  maxBytesPerRead="4096" maxNameTableCharCount="16384" />
 <security mode="Transport">
  <transport clientCredentialType="None" proxyCredentialType="None"
   realm="" />
  <message clientCredentialType="UserName" algorithmSuite="Default" />
 </security>
</binding>
</basicHttpBinding>

Let me know if you need any more details.

EDIT
OK, here's something I left out that might be causing the issue. This is all happening behind the company firewall.
Could it be that said firewall is preventing it from running from the website because it's an HTTP connection spawned from an existing "web process"? Whereas in the console app it's just a single connection.

您需要在 web.config 中添加代理旁路

  <system.net>
    <defaultProxy>
      <proxy
      usesystemdefault = "true"
      proxyaddress="http://theproxyaddress:PortNumber"
      bypassonlocal="false"
/>
    </defaultProxy>
  </system.net>

这将允许您通过防火墙打开与服务的连接

You need to add a proxy bypass in your web.config

  <system.net>
    <defaultProxy>
      <proxy
      usesystemdefault = "true"
      proxyaddress="http://theproxyaddress:PortNumber"
      bypassonlocal="false"
/>
    </defaultProxy>
  </system.net>

This will allow you to open a connection to the service through your firewalls
