HttpClient 实现跳转请求

abin — Thu, 27 Sep 2012 12:31:00 GMT

实现servlet的跳转，以输入流的形式来传输数据

测试UnionPayServlet的httpClient测试类：
package com.abin.lee.https;

import java.io.IOException;

import java.io.OutputStream;

import java.io.OutputStreamWriter;

import java.io.Writer;

import junit.framework.TestCase;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.client.HttpClient;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.entity.ContentProducer;

import org.apache.http.entity.EntityTemplate;

import org.apache.http.impl.client.DefaultHttpClient;

import org.apache.http.util.EntityUtils;

import org.junit.Test;

public class HttpClientTest extends TestCase {

private static final String Url = "http://localhost:9090/Spa/UnionPayServlet";

@Test

public void testHttpClient() throws Exception {

HttpClient client = new DefaultHttpClient();

HttpPost post = new HttpPost(Url);

ContentProducer create = new ContentProducer() {

public void writeTo(OutputStream outstream) throws IOException {

Writer writer = new OutputStreamWriter(outstream, "UTF-8");

writer.write("start");

writer.flush();

writer.close();

}

};

HttpEntity request = new EntityTemplate(create);

post.setEntity(request);

HttpResponse response = client.execute(post);

HttpEntity entity = response.getEntity();

String result = EntityUtils.toString(entity);

System.out.println("the last message is: "+result);

}

//被访问的servlet，也就是中间servlet

package org.litsoft.air.servlet;

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.io.OutputStreamWriter;

import java.io.Writer;

import javax.servlet.ServletException;

import javax.servlet.ServletOutputStream;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.client.HttpClient;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.entity.ContentProducer;

import org.apache.http.entity.EntityTemplate;

import org.apache.http.impl.client.DefaultHttpClient;

import org.apache.http.util.EntityUtils;

public class UnionPayServlet extends HttpServlet {

private static final String Url = "http://localhost:9090/Spa/changeServlet";

@Override

protected void doPost(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

System.out.println("UnionPayServlet");

String result=null;

BufferedReader reader=new BufferedReader(new InputStreamReader(request.getInputStream()));

int num=0;

char[] buffer=new char[1024];

while((num=reader.read(buffer))!=-1){

result=new String(buffer,0,num);

}

System.out.println("from HttpCLient message is: ="+result);

final String transfer=result;

HttpClient client = new DefaultHttpClient();

HttpPost post = new HttpPost(Url);

ContentProducer create = new ContentProducer() {

public void writeTo(OutputStream outstream) throws IOException {

Writer writer = new OutputStreamWriter(outstream, "UTF-8");

writer.write(transfer);

writer.flush();

writer.close();

}

};

HttpEntity httpEntity = new EntityTemplate(create);

post.setEntity(httpEntity);

HttpResponse httpResponse = client.execute(post);

HttpEntity entity = httpResponse.getEntity();

String result1 = EntityUtils.toString(entity);

// System.out.println(result1);

ServletOutputStream out=response.getOutputStream();

BufferedWriter writer=new BufferedWriter(new OutputStreamWriter(out));

writer.write("this message is received by UnionPayServlet is: "+result1);

writer.flush();

writer.close();

}

@Override

public void destroy() {

super.destroy();

}

//最终要处理的servlet

package org.litsoft.air.servlet;

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.io.PrintWriter;

import java.net.HttpURLConnection;

import java.net.URL;

import javax.servlet.ServletException;

import javax.servlet.ServletOutputStream;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.litsoft.air.unionpay.CreateJdomOne;

public class ChangeServlet extends HttpServlet {

@Override

protected void doPost(HttpServletRequest request,

HttpServletResponse response) throws ServletException, IOException {

// 接收Servlet传回来的信息

BufferedReader reader = new BufferedReader(new InputStreamReader(

request.getInputStream()));

String show = null;

StringBuffer stb = new StringBuffer();

while ((show = reader.readLine()) != null) {

stb.append(show);

}

System.out.println("from UnionPayServlet message is :" + stb.toString());

reader.close();

ServletOutputStream out=response.getOutputStream();

BufferedWriter writer=new BufferedWriter(new OutputStreamWriter(out));

writer.write("this message is received by ChangeServlet is :"+stb.toString());

writer.flush();

writer.close();

}

asterisk 常用命令

abin — Wed, 30 May 2012 09:19:00 GMT

1、运行调试常用命令

./asterisk & #后台启动
./asterisk -vvvc #启动asterisk 并尽量多的在后台显示调试信息
./asterisk -r #连接asterisk控制台
set verbose #设置打印信息

2、asterisk控制台下常用命令

set reload #重新加载sip配置信息
sip set debug on #设置显示更多的Sip信息
sip set debug off #关闭更多sip信息显示
sip show channels #显示活动的sip通道
sip show peers #显示已定义的sip peer
dialplan show #显示拨号方案
dialplan reload #重新加载拨号方案
stop gracefully #优雅的终止asterisk
stop now #立即停止asterisk
module show #显示所有已加载模块
module load xxxxx.so #加载xxxxx.so 模块
module reload xxxx.so #重新加载xxxx.so
module unload xxxx.so #卸载xxxx.so模块
core show applications #显示所有的应用如：Dial、Radius、Hangup、Answer等
core show channels #显示所有的通话频道
core show codecs #显示所有支持的编解码器
core show funcions #显示所有的功能函数
