    source code如下:

    
    import java.io.FileNotFoundException;
    import java.io.IOException;  
    import org.apache.commons.codec.binary.Base64;
    import org.apache.http.HttpEntity;  
    import org.apache.http.HttpResponse;  
    import org.apache.http.client.ClientProtocolException;  
    import org.apache.http.client.HttpClient;  
    import org.apache.http.client.methods.HttpPost;
    import org.apache.http.entity.mime.HttpMultipartMode;
    import org.apache.http.entity.mime.MultipartEntityBuilder;
    import org.apache.http.impl.client.DefaultHttpClient;
    import org.apache.http.util.EntityUtils;
     
    @SuppressWarnings("deprecation")
    public class MyHTTPPost 
    {
     final private static String POST_PREFIX = <replace with your own application server url>;
     
     private static String getRequestURL(String str)
     {
     String url = POST_PREFIX + str;
            url = url + "&sid=" + Math.random();
             return url;
     }
     
     private static void sendHTTPPostRequest(String str) throws FileNotFoundException
     { 
     HttpClient httpclient = new DefaultHttpClient();
     String raw = "WANGJER:Saptest1"; 
     String encoded = Base64.encodeBase64String(raw.getBytes());
     
            HttpPost httppost = new HttpPost(getRequestURL(str));
            MultipartEntityBuilder builder = MultipartEntityBuilder.create();        
            builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
            
            builder.addTextBody("firstName", "Jerry");
            builder.addTextBody("lastName", "Wang");
            try {
                httppost.addHeader("Content-Type","multipart/form-data; boundary=assdsfdffafasf");
                httppost.addHeader("User-Agent","Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)");
                httppost.addHeader("Authorization", "Basic " + encoded);  
                
                HttpResponse httpresponse = httpclient.execute(httppost);
                HttpEntity resEntity = httpresponse.getEntity();
                String response = EntityUtils.toString(resEntity);
                System.out.println(response);
            }
            catch (IOException e)
            {
             System.out.println(e.getLocalizedMessage());
             e.printStackTrace();
             System.out.println("error!");
            }
     }
     
     public static void main(String[] args) throws ClientProtocolException, IOException  
     {  
     sendHTTPPostRequest("a");
     }  
    }
    
    
    

    运行结果:

    application server会解析出Java program传入的http 请求中的"a", 然后从DB table scarr 中查找对应的记录,返回给Java side:

    
    <a href=’http://www.aa.com’ target=’_blank’>American Airlines</a><br /><a href=’http://www.aircanada.ca’ target=’_blank’>Air Canada</a><br /><a href=’http://www.airfrance.fr’ target=’_blank’>Air France</a><br /><a href=’http://www.alitalia.it’ target=’_blank’>Alitalia</a><br /><a href=’http://www.british-airways.com’ target=’_blank’>British Airways</a><br /><a href=’http://www.airpacific.com’ target=’_blank’>Air Pacific</a><br /><a href=’http://www.continental.com’ target=’_blank’>Continental Airlines</a><br /><a href=’http://www.delta-air.com’ target=’_blank’>Delta Airlines</a><br /><a href=’http://www.airberlin.de’ target=’_blank’>Air Berlin</a><br /><a href=’http://www.lufthansa.com’ target=’_blank’>Lufthansa</a><br /><a href=’http://www.laudaair.com’ target=’_blank’>Lauda Air</a><br /><a href=’http://www.jal.co.jp’ target=’_blank’>Japan Airlines</a><br /><a href=’http://www.nwa.com’ target=’_blank’>Northwest Airlines</a><br /><a href=’http://www.qantas.com.au’ target=’_blank’>Qantas Airways</a><br /><a href=’http://www.saa.co.za’ target=’_blank’>South African Air.</a><br /><a href=’http://www.singaporeair.com’ target=’_blank’>Singapore Airlines</a><br /><a href=’http://www.ual.com’ target=’_blank’>United Airlines</a>
