在运行时更改web服务URL

本文关键字:服务 URL web 运行时 | 更新日期: 2023-09-27 18:04:11

我正在开发一个应用程序,它将根据用户的位置连接到各种Web服务。

例如:

如果用户在城市"A",应用程序将连接到Web服务:"192.168.1.1:8010",如果他去城市"B",将连接到"192.168.1.1:8020",在城市"C"将连接到"192.168.1.1:8030",以此类推。

IP地址始终不变,改变的是端口号

很简单吧?是的,但是我找不到让它在运行时工作的方法!

当我在运行时更改Web服务("URL行为==动态")的"URL"参数(myWS.Url)时,服务器只返回null,将参数更改为原始值,通信恢复。

同样,如果在编译前做了更改,则编译到城市"A",仅在城市"A"中有效,编译到城市"B",仅在城市"B"中有效。

该应用程序最初是使用VS2008和CF3.5为Windows CE 5.0开发的,但即使在VS2013中使用。. NET Framework 4.0和Windows 7的"问题"仍然发生。

有人经历过吗?

按照要求,这里是我的一小部分代码:

WSR.WSR myWS = new WSR.WSR();
//WSR added as a Web Reference
if (City_A)
{
    myWS.Url = "http://192.168.1.1:8010/WSR.apw";
}
else
{
    myWS.Url = "http://192.168.1.1:8020/WSR.apw";
}

本主题的解决方案(应该修改什么来改变c#中web服务的URL ?)不适合我,因为,正如我所说,当我改变"URL行为"属性时,没有在我的app.config文件中创建入口点。

下面是app.config文件:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
            <section name="TrocaWebService.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <startup> 
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/></startup>
    <system.serviceModel>
        <bindings />
        <client />
    </system.serviceModel>
    <userSettings>
        <TrocaWebService.Properties.Settings>
            <setting name="TrocaWebService_WSR_WSR" serializeAs="String">
                <value>http://192.168.1.1:8010/WSR.apw</value>
            </setting>
        </TrocaWebService.Properties.Settings>
    </userSettings>
</configuration>

在运行时更改web服务URL

我正在使用WCF绑定(Visual Studio -> Add Service Reference)来针对WSDL创建代理类。然后在运行时,我将使用以下代码创建一个ClientBase(它有一个端点(即url)):

public static class ServiceClientFactory
{
    public static HttpBindingBase BuildBinding(string endpointUrl)
    {
        if (endpointUrl.ToLower().StartsWith("https"))
        {
            var binding = new BasicHttpsBinding(BasicHttpsSecurityMode.Transport);
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;
            binding.MaxReceivedMessageSize = int.MaxValue - 1;
            return binding;
        }
        else
        {
            var binding = new BasicHttpBinding(BasicHttpSecurityMode.TransportCredentialOnly);
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;
            binding.MaxReceivedMessageSize = int.MaxValue - 1;
            return binding;
        }
    }
    public static TClient CreateClient<TClient, TChannel>(string endpoint, string username, string password)
        where TClient : ClientBase<TChannel>
        where TChannel : class
    {
        var client = (TClient)
            Activator.CreateInstance(
                typeof (TClient),
                BuildBinding(endpoint),
                new EndpointAddress(endpoint));
        if (null == client.ClientCredentials)
            throw new Exception(
                string.Format("Error initializing [{0}] client.  Client Credentials object was null",
                    typeof(TClient).Name));

       //This is for setting Basic Auth
       client.ClientCredentials.Windows.ClientCredential =
            new NetworkCredential(
                username,
                password);
        client.ClientCredentials.Windows.AllowedImpersonationLevel =
            TokenImpersonationLevel.Delegation;
       return client;
    }
}
