使用python的requests库简单爬取,使用xpath解析内容
可以获取个人信息、个人照片、成绩单和课表
github地址：https://github.com/PythonerKK/GZCC-Spider
首先使用浏览器开发者调试工具找到登录页面的准确地址：http://jwxw.gzcc.cn/default2.aspx
然后找到验证码的地址：http://jwxw.gzcc.cn/CheckCode.aspx
将验证码保存让用户输入即可
登录时发送POST请求，需要注意要提交一个叫__VIEWSTATE的字段，并且要携带cookies
发送POST后，如果登录成功则返回用户页面，判断即可
__VIEWSTATE=re.compile('name="__VIEWSTATE" value="(.*?)"').findall(data.text)[0]
resource=requests.post(login_url,data=post_data,cookies=cookies,headers=headers).text
if '活动报名' in resource:
print('登录成功！')
dom_tree=etree.HTML(resource)
name=dom_tree.xpath('//span[@id="xhxm"]/text()')
name=name[0]
print('欢迎回来 '+name)
return (cookies,name.split('同')[0])
else:
print('登录失败！')
exit(0)登录成功，输出：xxx同学，你好！
接下来需要获取个人信息、个人照片、成绩单
原理同上，注意携带cookies，成绩页面获取还需要携带__VIEWSTATE字段
效果如下：
