前端是当页面加载完成才弄下一次请求，利用ajax请求，当status=408时，一直在加载请求，当status=201时,获取用户头像一直加载请求，直到status=200才跳转到另一个页面，涉及到登陆记得加cookie
返回的ticket如下：
<error>
<ret>0</ret>
<message></message> <skey>@crypt_dd043c47_d6303d6aed797c295a21960d9c2d729c</ske y> <wxsid>hYiHcYEqVMC4Kim9</wxsid> <wxuin>795592819</wxuin> <pass_ticket>aNUg%2B%2FHFbBavV3w9ndTBh8hjSErIhrkBBGVl0PV F%2B9lQhFi5KtGYjlWCv2%2FoBrQf</pass_ticket>
