Curl is a popular command-line tool that can send requests to a server using protocols like HTTP and HTTPS. It is a good tool to communicate with RESTful Web services because it can send content by any HTTP method. Curl is already distributed with Linux® and Mac, and there is a utility that you can install for the Windows® platform (see Resources).

XML-RPC的全U是XML Remote Procedure CallQ即XMLq程Ҏ调用? 它是一套允许运行在不同操作pȝ、不同环境的E序实现ZInternetq程调用的规范和一pd的实现? q种q程q程调用使用http作ؓ传输协议QXML作ؓ传送信息的~码格式。Xml-Rpc的定义尽可能的保持了单，但同时能够传送、处理、返回复杂的数据l构? XML-RPC是工作在Internet上的q程q程调用协议。一个XML-RPC消息是一个请求体为xml的http-posthQ被调用的方法在服务器端执行q将执行l果以xml格式~码后返回? Request example Here's an example of an XML-RPC request: POST /RPC2 HTTP/1.0User-Agent: Frontier/5.1.2 (WinNT)Host: betty.userland.comContent-Type: text/xmlContent-length: 181 <?xml version="1.0"?> <methodCall> <methodName>examples.getStateName</methodName> <params> <param> <value><i4>41</i4></value> </param> </params> </methodCall> Response example Here's an example of a response to an XML-RPC request: HTTP/1.1 200 OKConnection: closeContent-Length: 158Content-Type: text/xmlDate: Fri, 17 Jul 1998 19:55:08 GMTServer: UserLand Frontier/5.1.2-WinNT <?xml version="1.0"?> <methodResponse> <params> <param> <value><string>South Dakota</string></value> </param> </params> </methodResponse> ?XML-RPC入门E序 以下的入门程序包括一个管理器QHelloHandlerQ、一个服务器QHelloServerQ、一个客L序（HelloClientQ? 首先要做的是创徏用于q程q程调用的类和方法，Z常常UC为管理器。Xml-rpc理器是一个方法和Ҏ集，它接受xml-rpchQƈ对请求的内容q行解码Q再向一个类和方法发求? //理器类 package xmlRpc; /** * @author trier * * <b><code>HelloHandler</code></b> is a simple handler than can * be registered with an XML-RPC server */ public class HelloHandler { public String sayHello(String name){ return "Hello " + name; } } 服务器程序将创徏的管理器注册到服务器上，qؓ服务器指明应用程序其他特定的参数? //服务器类 package xmlRpc; /** * * <b><code>HelloServer</code></b> is a simple XML-RPC server * that will take the <code>HelloHandler</code> class available * for XML-PRC calls. * <o:p */ import org.apache.xmlrpc.WebServer; import org.apache.xmlrpc.XmlRpc; import java.io.IOException; public class HelloServer { public static void main(String[] args){ if(args.length<1){ System.out.println("Usage: java HelloServer [port]"); System.exit(-1); } try{ XmlRpc.setDriver("org.apache.xerces.parsers.SAXParser"); //start the server System.out.println("Starting XML-RPC Server......"); WebServer server = new WebServer(Integer.parseInt(args[0])); //register our handler class server.addHandler("hello",new HelloHandler()); System.out.println("Now accepting requests......"); }catch(ClassNotFoundException e){ System.out.println("Could not locate SAX Driver"); }catch(IOException e){ System.out.println("Could not start server: "+e.getMessage()); } } } //客户E序 package xmlRpc; /** * * <b><code>HelloClient</code></b> is a simple XML-RPC client * that makes an XML-RPC request to <code>HelloServer</code> */ import java.io.IOException; import java.util.Vector; import org.apache.xmlrpc.XmlRpc; import org.apache.xmlrpc.XmlRpcClient; import java.net.MalformedURLException; import org.apache.xmlrpc.XmlRpcException; public class HelloClient { public static void main(String[] args){ if(args.length<1){ System.out.println("Usage: java HelloClient [your name]"); System.exit(-1); } try{ //Use the Apache Xereces SAX Driver XmlRpc.setDriver("org.apache.xerces.parsers.SAXParser"); //Specify the server XmlRpcClient client = new XmlRpcClient("http://localhost:8585"); //create request Vector params = new Vector(); params.addElement(args[0]); //make a request and print the result String result = (String)client.execute("hello.sayHello",params); System.out.println("Response from server: "+ result); }catch(ClassNotFoundException e){ System.out.println("Could not locate SAX Driver"); }catch(MalformedURLException e){ System.out.println("Incorrect URL fro xml-rpc server foramt:"+e.getMessage()); }catch(XmlRpcException e){ System.out.println("XmlRpcException :"+e.getMessage()); }catch(IOException e){ System.out.println("IOException:"+e.getMessage()); } } } ?RPC和RMI的简单比? 在RMI和RPC之间最主要的区别在于方法是如何别调用的。在RMI中，q程接口使每个远E方法都hҎ{。如果一个方法在服务器上执行Q但是没有相匚w的签名被d到这个远E接口上Q那么这个新Ҏ׃能被RMI客户Ҏ调用。在RPC中，当一个请求到达RPC服务器时Q这个请求就包含了一个参数集和一个文本|通常形成“classname.methodname”的Ş式。这向RPC服务器表明，被请求的Ҏ在ؓ“classname”的类中，名叫“methodname”。然后RPC服务器就L索与之相匚w的类和方法，q把它作为U方法参数类型的输入。这里的参数cd是与RPCh中的cd是匹配的。一旦匹配成功，q个Ҏp调用了，其结果被~码后返回客h?
