案例1:import org.apache.commons.httpclient.*; import org.apache.commons.httpclient.methods.*; import org.apache.commons.httpclient.params.Http ...

案例1:

import org.apache.commons.httpclient.*; import org.apache.commons.httpclient.methods.*; import org.apache.commons.httpclient.params.HttpMethodParams;  import java.io.*;  public class HttpClientTutorial {    private static String url = "http://10.129.39.149:8090/ajax/loginMgt/login.action";   public static void method(HttpClient client,String url,String body){    PostMethod method = new PostMethod(url);     //"count":10,"ignoreCase":"false","paras":["a%"],"queryId":"getMenu"     NameValuePair[] postData = new NameValuePair[]{};      //postData[0] = new NameValuePair("count", 10);      method.setRequestBody(body);//addParameters(postData);                // Provide custom retry handler is necessary     /*method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,         new DefaultHttpMethodRetryHandler(3, false));*/      try {      // Execute the method.      int statusCode = client.executeMethod(method);       if (statusCode != HttpStatus.SC_OK) {       System.err.println("Method failed: " + method.getStatusLine());      }       // Read the response body.      byte[] responseBody = method.getResponseBody();       // Deal with the response.      // Use caution: ensure correct character encoding and is not binary data      System.out.println(new String(responseBody,"utf-8"));     } catch (HttpException e) {       System.err.println("Fatal protocol violation: " + e.getMessage());       e.printStackTrace();      } catch (IOException e) {       System.err.println("Fatal transport error: " + e.getMessage());       e.printStackTrace();      } finally {       // Release the connection.       method.releaseConnection();      }   }    public static void main(String[] args) {   // Create an instance of HttpClient.   HttpClient client = new HttpClient();      String body ="[{\"userId\":1,\"password\":1}]";   // Create a method instance.   method(client,url,body);      url = "http://10.129.39.149:8090/ajax/getInitValueArr.action";      body = "[{\"count\":10,\"ignoreCase\":\"false\",\"paras\":[\"a%\"],\"queryId\":\"getMenu\"}]";   method(client,url,body);  } }

案例2:

  HttpClient c = new HttpClient();    HttpMethod m = new GetMethod(); String path =msnListPath+"?account="+userSimpleInfo.getMsnAccount()+"&type=msn&uid="+userSimpleInfo.getPassportId()+"&pwd="+userSimpleInfo.getMsnPassword();  m.setPath(path);   String response="";	  int status = 0;   try {   status = c.executeMethod(m);	if(status == HttpStatus.SC_OK) {	byte[] rbytes = m.getResponseBody(); response = new String(rbytes,"UTF-8"); return response;	} } catch (HttpException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return "error";
