Simple case of getting web cookies

Original link: https://blog.saky.site/post/web-cookie/

For example the original cookie for a web page is

 uu=hfsjfyesu;

The cookie after successful login is

 userId=558456454; token=wwwdwblogcnwwwdwblogcnwwwdwblogcnwwwdwblogcnwwwdwblogcn; uu=hfsjfyesu; pin=sirhexs

Then we first write an if statement to determine whether the login is successful

 if(webcookie:find"token=")then --上面这个if的意思是判断webcookie里面是否存在“token=”这个字符串--这里是登录成功后要进行的操作,我们在这里写我们的cookie截取规则end

Then we write a rule to intercept the token according to the rules and code api

Code to use:

 str="左中右" --取字符串左边左=str:match("(.+)中") --取字符串中间中=str:match("左(.-)右") --取字符串右边右=str:match("中(.+)")

accomplish:

 if(webcookie:find"token=")then cookie="token="..webcookie:match("token=(.-)uu=") --上面这行的意思是截取“token=”到“uu=”中间的这段字符串,然后拼接到“token=”的后面,“..”这两个点相当于一个加号,用来拼接两端字符串。 mycookietxt.setText(cookie)--设置文本内容cookielay.setVisibility(View.VISIBLE)--显示控件end

This completes the interception of a cookie.

Complete code reference (take Ele.me as an example):

Several other commonly used software grab the key code of ck :

JD.com

 loginurl="https://plogin.m.jd.com/login/login?appid=445&returnurl=https%3A%2F%2Fm.healthjd.com%2F%3Fyyjdfromflag%3Dlogin" if(webcookie:find"pt_key")then --正则截取ck cookie0=webcookie:match("pt_key=(.-)pt_token") --补全cookie cookie="pt_key="..cookie0 if(cookie:find"pwdt_id") then cookie=cookie:match("(.+)pwdt_id") end mycookietxt.setText(cookie)--设置文本内容cookielay.setVisibility(View.VISIBLE)--显示控件end
