现在URL作为API的情况越来越多了，如：BlackBerry,F-Secure等提供客户的接口就是通过URL. 客户通过URL提出请求，处理后再通过页面返回处理结果。
作为处理着类case, Java是非常好的选择。
在工作中也常遇到这类case，现在就分享下代码。[@more@]import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.*;

public class Http_RepSMS {
private static String DEBUG;

public static void main (String args[]){
try{
if (args.length != 1){
System.out.println("Usage: java Http_ReqSMS ");
System.exit(1);

}

String url = args[0];
Http_RepSMS Run_Http_ReqSMS = new Http_RepSMS();
String re = Run_Http_ReqSMS.get_http(url);
//String re = "0[Send SMS success]";
//String re = "103[Incorrect password]";
System.out.println(re);
}
catch (Exception ex){
System.out.println("Error: "+ex);
}
}

public String get_http(String url) {
String tmpResult = null;
String result = null;
try {
URL urlObj = new URL(url);
URLConnection URLConnectionObj = urlObj.openConnection();
BufferedReader dataStream = new BufferedReader ( new InputStreamReader(URLConnectionObj.getInputStream()));
while ( (tmpResult = dataStream.readLine()) != null){
result = result + tmpResult;
}
}
catch (Exception ex){
System.out.println("Error: "+ex);
result = "Error: "+ex;
}
return result;
}
}
