访问快递100的rest的请求

转:http://blog.csdn.net/u011115507/article/details/9172679

查快递的时候发现了一个http://www.kaidi100.com 是金蝶旗下的下个网站，做得很不错，几乎可以查所以的快递公司的，该站提供了API查询快递，API需要申请key.申请Key需要做它网站链接。无奈，哥的网站早到期，没续费了，于是trace了一把请求，直接用Java httpurlconnection 搞起，只是给个例子，可以再接着封装。中间遇到过乱码问题，最后发现是内容进行了gzip压缩，trace时候没有仔细看response header ,吃了回亏 教训。
