使用代理后面的.Net Core 2.0连接到SOAP服务 [英] Connecting to a SOAP service with .Net Core 2.0 behind a proxy

问题描述

我正在使用Visual Studio 2017。

I'm using Visual Studio 2017.

我注意到，当位于.NET Core 2.0后面时，无法从.Net Core 2.0连接到SOAP服务。代理（当直接连接到Internet时它正在工作，并且当从.Net Core 1.1应用程序通过代理连接时它也正在工作）。

I have noticed that it was not possible to connect to a SOAP service from a .Net Core 2.0 when being behind a proxy (when connected directly to the internet it's working and when connecting through the proxy from a .Net Core 1.1 app it's working too).

我创建了一个小测试程序（控制台应用程序）调用公共SOAP服务（ http://www.webservicex.net/globalweather.asmx ）。
通过更改该程序的目标（.Net Core 1.1 / .Net Core 2.0），我可以重现此问题。

I have created a little test program (Console app) that calls a public SOAP service (http://www.webservicex.net/globalweather.asmx). By changing the target of this program (.Net Core 1.1 / .Net Core 2.0) I can reproduce the problem.

以下是示例代码（ VS 2017的Connected Services组件已生成用于连接到Web服务的类）。

Here is the sample code (the classes for connecting to the web service have been generated with VS 2017's Connected Services component):

BasicHttpBinding binding = new BasicHttpBinding();

EndpointAddress address = new EndpointAddress("http://www.webservicex.net/globalweather.asmx");

GlobalWeatherSoapClient client = new GlobalWeatherSoapClient(binding, address);

var response = client.GetCitiesByCountryAsync("France").Result;

我已经完成了网络捕获（使用Wireshark），当发生此问题时，我看不到任何HTTP请求从我的计算机出来。
有人知道出了什么问题吗？

I have done a network capture (with Wireshark) and when this problem happens I can see no HTTP request coming out from my computer. Does anybody know what is going wrong ? Maybe I am not calling this service the right way.

预先感谢

推荐答案

我遇到了同样的问题，Wireshark中没有传出的http请求。该项目必须使用具有凭据的公司代理才能连接到https地址，因此设置了BasicHttpSecurityMode.Transport。

I had the same problem, no outgoing http requests in Wireshark. The project had to use a corporate proxy with credentials to connect to a https address, thus BasicHttpSecurityMode.Transport was set.

原因是带有代理设置的.net Core 2.0中的错误。它没有使用WinINet（IE / Edge）代理设置，并且您无法配置单独的代理，更多信息请参见 https://github.com/dotnet/wcf/issues/1592 。

The reason was a bug in .net Core 2.0 with proxy settings. It hasn't used the WinINet (IE/Edge) proxy settings and you wasn't able to configure a separate proxy, more info here https://github.com/dotnet/wcf/issues/1592.

将项目升级到.net Core 2.1之后，并更新System.ServiceModel.Http等依赖于最新的稳定版本（以我的情况为4.5.3），则使用IE / Edge代理设置。

After upgrading the project to .net Core 2.1, and update System.ServiceModel.Http and other dependcies to latest stable (4.5.3 in my case), the IE/Edge proxy settings are used.
