Sogou-php get crawl page URL after getting jump

Sogou PHP

Crawl page:
Http://weixin.sogou.com/weixin?type=2&ie=utf8&query=%E9%98%85%E5%85%B5
within the link;
But in the middle to go through a step, Sogou did jump.
Example: Http://weixin.sogou.com/websearch/art.jsp?sg=xaXJ7lM8QYSJRqlJNRlxrvDoJgDV2b9Zxfx-iaQmaX_ Uirnutv72iqqdclhjdqgxwl_uhruejyg2c6h9onyfcraowdr5nk5vixhygxj6kqt1_yad5qrt7y0qfcahxotg&url= P0ovdh8r4shyuysb8e88hkjm8gf_ mcjfbfynrtbn8wjzz2w8jb8ver6lwqp4ghrvxy6rlcsg2ksnsf3cfbpwovlvkvbrfa0sfw2qjse-dg7w8ccsjpcm6mcecbs6yayt3u7-yrc86qryy-5x5in7j Jfmexjqcxhpkyjfvwp6pugcq64lgq2zdmuqxplqrsbk
After the jump is the real url:http://mp.weixin.qq.com/s?__biz=mjm5odeznzk2mw==&mid=209558006&idx=2&sn= 8f839662eef543180656253625474837&3rd=mza3mdu4ntyzmw==&scene=6#rd
