广州商学院Python正方教务系统爬虫(获取个人信息成绩课表修改密码)

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：
