Question

我通过https连接到wcf服务有问题。我没有创建wcf服务。在Internet Explorer中，当我设置url end打开页面时，请让我写用户名和密码。

我打开了新的C＃项目，想要添加新的服务引用，但每次出错：

下载＆＃39; https://address/path/service.svc/_vti_bin/ListData.svc/ $元数据＆＃39;时出错。底层连接已关闭：发送时发生意外错误。无法从传输连接读取数据：远程主机强制关闭现有连接。远程主机强制关闭现有连接元数据包含无法解析的引用：＆＃39; https://address/path/service.svc.svc＆＃39;。向https://address/path/service.svc.svc发出HTTP请求时发生错误。这可能是由于在HTTPS情况下未使用HTTP.SYS正确配置服务器证书。这也可能是由客户端和服务器之间的安全绑定不匹配引起的。底层连接已关闭：发送时发生意外错误。无法从传输连接读取数据：远程主机强制关闭现有连接。远程主机强制关闭现有连接如果在当前解决方案中定义了服务，请尝试构建解决方案并再次添加服务引用。

我还尝试下载wsdl文件，并在添加服务引用时添加了本地wsdl文件。它通过但现在当我开始客户端时我得到了例外：

未提供用户名。在ClientCredentials中指定用户名。

try
{
    ServiceReference1.IService stub = new ServiceReference1.ServiceClient();
    stub.calculate("test");
}
catch (Exception ee)
{
}

但我在stub对象???

中没有ClientCredentials的选项

的app.config

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.1"/></startup>
<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IService">
                <security mode="Transport">
                    <transport clientCredentialType="Basic" proxyCredentialType="Basic" />
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="https://address/path/service.svc"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IService"
            contract="ServiceReference1.IService" name="BasicHttpBinding_IService" />
    </client>
</system.serviceModel>

我该如何解决这个问题？

Answer 1

definition之前的{p> ServiceClient有一个名为ClientCredentials的属性，但IService没有。也许尝试将变量类型从IService更改为ServiceClient？

ServiceReference1.ServiceClient stub = new ServiceReference1.ServiceClient();
stub.ClientCredentials.UserName.UserName = username;  
stub.ClientCredentials.UserName.Password = password;  

// Treat the test certificate as trusted  
stub.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.PeerOrChainTrust;

我在调用方法前放了：

                System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3;

代码：

            System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3;            //System.Net.ServicePointManager.
        try
        {
            var stub = new ServiceReference1.ServiceClient();
            stub.ClientCredentials.UserName.UserName = "user";
            stub.ClientCredentials.UserName.Password = "pass";
            //stub.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.PeerOrChainTrust;
            //System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3;

            stub.calculate("Test");
        }
        catch (Exception ee)
        {
        }
