.net 调用外部的webservice接口

需求:做这个项目之前需要用到一个java的webservice接口,首先想到的第一种方法就是添加服务引用了.但是这样的话会有一个config文件 生成的dll必须要读取config文件,config文件放到同一目录也不行的,需要放到另一个工具的节点中才能被另外一个工具读取,不幸的是另外一个工具不能添加节点 否者会boom

二:接下来就是只能手写地址写进去程序里面.然后在百度搜索了一下文章.代码不出意外的粘贴复制,然后自己写个c#的webserive测试完全没问题..发现给java用时候就不行了.百思不得其解,报错找不到命名空间之类的,那就不折腾了.

三:wcf提供的吧. 首先需要一个工厂方法和一个代理类.代理类可以用wcf工具生成,具体步骤如下http://blog.163.com/[email protected]/blog/static/3743053820132133616282/引用别人写的吧  照着做就行这是原地址.这个时候就拿到了一个代理类,然后找一个工厂的方法

public static T CreateServiceByUrl<T>(string url)
{
return CreateServiceByUrl<T>(url, "basicHttpBinding");
}

public static T CreateServiceByUrl<T>(string url, string bing)
{
try
{
if (string.IsNullOrEmpty(url)) throw new NotSupportedException("This url is not Null or Empty!");
EndpointAddress address = new EndpointAddress(url);
Binding binding = CreateBinding(bing);
ChannelFactory<T> factory = new ChannelFactory<T>(binding, address);
return factory.CreateChannel();
}
catch (Exception ex)
{
throw new Exception("创建服务工厂出现异常.");
}
}
#endregion

#region 创建传输协议
/// <summary>
/// 创建传输协议
/// </summary>
/// <param name="binding">传输协议名称</param>
/// <returns></returns>
private static Binding CreateBinding(string binding)
{
Binding bindinginstance = null;
if (binding.ToLower() == "basichttpbinding")
{
BasicHttpBinding ws = new BasicHttpBinding();
ws.MaxBufferSize = 2147483647;
ws.MaxBufferPoolSize = 2147483647;
ws.MaxReceivedMessageSize = 2147483647;
ws.CloseTimeout = new TimeSpan(0, 30, 0);
ws.OpenTimeout = new TimeSpan(0, 30, 0);
ws.ReceiveTimeout = new TimeSpan(0, 30, 0);
ws.SendTimeout = new TimeSpan(0, 30, 0);

bindinginstance = ws;
}
else if (binding.ToLower() == "nettcpbinding")
{
NetTcpBinding ws = new NetTcpBinding();
ws.MaxReceivedMessageSize = 65535000;
ws.Security.Mode = SecurityMode.None;
bindinginstance = ws;
}
else if (binding.ToLower() == "wshttpbinding")
{
WSHttpBinding ws = new WSHttpBinding(SecurityMode.None);
ws.MaxReceivedMessageSize = 65535000;
ws.Security.Message.ClientCredentialType = System.ServiceModel.MessageCredentialType.Windows;
ws.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Windows;
bindinginstance = ws;
}
return bindinginstance;

}

然后下面就是使用的代码了

string url = "这里填写你的接口地址";

客户端生成的接口名 例如public interface AA就这样写

AA a=WcfInvokeFactory.CreateServiceByUrl<AA>(url);

a.方法(new 代理类里面需要调用传参的方法("参数"));
