如何用java创建一个request,并用post的方法发送这个request
大家应该都知道www.51job.com这个网站吧.
我现在想模仿浏览器实现搜索所有全文带有"java"关键字的职位.
51job分普通搜索和高级搜索,我是按普通搜索的,搜索"全文".如下图1
图1
点击搜索之后,浏览器会自动发出一个post的请求,然后51job会返回来一个响应,
这些都被万恶的我截取了下来,哈哈.
如下两个图(图2和图3)
图2
图3
图中红色部分是返回来的response,可能对你的回答没有用
求一段java代码,能够模仿浏览器发出图2和图3所示的request,用到的技术可能是HttpURLConnection,
apache的httpcomponents或httpclient,不过只要你能用java代码实现我要的功能,用什么框架都行.
下面是图中大量的字符,供大家复制.

[解决办法]
/*连接http://192.168.1.66:8080/regSite，并向其传递参数*/
try{
URL url = new URL("http://192.168.1.66:8080/regSite");//Will be change to www.minma.com
HttpURLConnection urlcon = (HttpURLConnection) url.openConnection();
urlcon.setDoOutput(true);
urlcon.setRequestMethod("POST");
OutputStream buf = new BufferedOutputStream(urlcon.getOutputStream());
OutputStreamWriter out = new OutputStreamWriter(buf,"UTF-8");
/*向regSite传递5个参数*/
out.write("domain="+domain+"&tradeType="+tradeType+"&catalog="+catalog+"&pnum="+pnum+"&version=1.0");
out.flush();
out.close();
InputStream in = urlcon.getInputStream();
in.close();
/*读取访问页面内容*/
BufferedReader br=new java.io.BufferedReader(new InputStreamReader(in));
System.out.println("==================Beging====================");
String s=null;
while((s = br.readLine()) != null){
result+=s;
in.close();
System.out.println(result);
System.out.println("===================End======================");
}
}catch(Exception e){
System.out.println("Network not connect.");
System.out.println(e.getStackTrace());
}
[解决办法]
你能告诉我,你截取他们有什么作用吗?
你可以自己试着写这个功能,他的技术可以参考
[解决办法]
看一下httpconnection类
[解决办法]
用HttpClient类可以实现，看一下想关的api
[解决办法]
高手，向你学习！
[解决办法]
httpclient(apache commons) or httpconnection(jdk)
