Connecting to an asmx webservice with WCF through a proxy
提问by KeesDijk
Sorry answer found while typing
打字时找到抱歉的答案
I am trying to connect to an external webservice that requires username/password authentication through a proxy. I am using Visual Studio Express 2008 to generate a service reference
我正在尝试通过代理连接到需要用户名/密码身份验证的外部 Web 服务。我正在使用 Visual Studio Express 2008 生成服务引用
- I have connected to the same webservice using a web reference.We only had to set a larger timeout because it takes a long time to finish.
- I have connected to another webservice that does not require username/password authentication with a generated service reference and some settings to get it through the proxy.
- 我已经使用网络引用连接到同一个网络服务。我们只需要设置一个更大的超时，因为它需要很长时间才能完成。
- 我已经连接到另一个不需要用户名/密码身份验证的 Web 服务，并使用生成的服务引用和一些设置来通过代理获取它。
So my thought would be to take this reference, point it to the correct webservice and add authentication.
所以我的想法是获取此参考，将其指向正确的 Web 服务并添加身份验证。
The config I am using without security:
我在没有安全性的情况下使用的配置：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.net>
<defaultProxy useDefaultCredentials="true">
<proxy bypassonlocal="False" proxyaddress="http://***.***.****:80" />
</defaultProxy>
</system.net>
<system.serviceModel>
<bindings>
<customBinding>
<binding name="AreaWebServiceSoap12">
<textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
messageVersion="Soap12" writeEncoding="utf-8">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</textMessageEncoding>
<httpTransport manualAddressing="false" maxBufferPoolSize="524288"
maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Anonymous"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
keepAliveEnabled="true" maxBufferSize="65536" proxyAuthenticationScheme="Anonymous"
realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
useDefaultWebProxy="true" />
</binding>
</customBinding>
</bindings>
<client>
<endpoint address="http://www.****.*****.****.com/samplewebservice/service.asmx"
binding="customBinding" bindingConfiguration="AreaWebServiceSoap12"
contract="ServiceReference1.ServiceSoap" name="ServiceSoap" />
</client>
</system.serviceModel>
</configuration>
I have added te following code to my call for authentication:
我已将以下代码添加到我的身份验证调用中：
static void Main(string[] args)
{
ServiceSoapClient s = new ServiceSoapClient();
s.ClientCredentials.UserName.UserName = @"username";
s.ClientCredentials.UserName.Password = @"password";
Service.RawGpsData[] result = s.GetRawGpsData(0);
Console.WriteLine(String.Format("done:{0}",result.Length));
Console.ReadLine();
}
Just using this setup gives an error as expected:
仅使用此设置会按预期出现错误：
The HTTP request is not authorized with client authentication scheme Anonymous. The authentication header from the server is received, is NTLM.
HTTP 请求未通过客户端身份验证方案 Anonymous 授权。收到来自服务器的身份验证标头，是 NTLM。
Now I get lost and start trying silly things because I am just starting to use WCF.
现在我迷路了并开始尝试愚蠢的事情，因为我刚刚开始使用 WCF。
When I add the following section to the config
当我将以下部分添加到配置时
<security authenticationMode="UserNameOverTransport"></security>
I get the following error:
我收到以下错误：
The binding CustomBinding.http: / / tempuri.org / for the contract AreaWebServiceSoap.AreaWebServices is configured with a verification mode for which a transport level with integrity and confidentiality is required. The transport can not provide integrity and confidentiality.
合约AreaWebServiceSoap.AreaWebServices 的绑定CustomBinding.http://tempuri.org/ 配置了验证模式，该模式需要具有完整性和机密性的传输级别。传输不能提供完整性和机密性。
Sorry, while typing this question I stumbled upon the answer myself. I still think people might be interested in this and all comments and thoughts are still welcome. So I will leave the question here and make it community and post the answer myself.
抱歉，在输入这个问题时，我自己偶然发现了答案。我仍然认为人们可能对此感兴趣，并且仍然欢迎所有评论和想法。所以我会把这个问题留在这里，让它成为社区并自己发布答案。

Change the binding to :
将绑定更改为：
<?xml version="1.0" encoding="utf-8" ?>
<customBinding>
<binding name="AreaWebServiceSoap12" closeTimeout="00:01:00" openTimeout="00:10:00"
receiveTimeout="00:20:00" sendTimeout="00:05:00">
<textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
messageVersion="Soap12" writeEncoding="utf-8">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</textMessageEncoding>
<httpTransport manualAddressing="false" maxBufferPoolSize="524288"
maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Ntlm"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
keepAliveEnabled="true" maxBufferSize="65536" proxyAuthenticationScheme="Anonymous"
realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
useDefaultWebProxy="true" />
</binding>
</customBinding>
So set authenticationScheme="Ntlm"
所以设置 authenticationScheme="Ntlm"
