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.
