question
Because the sessionid requested by the applet on the applet is inconsistent, the backend cannot obtain the session
Solution
Get sessionid when logging in
//Save to the interface for the first timesessionidmiddle
success: function (res) {
();
('sessionid');//Clear cache every time you log in if ( == "0000") {
if ([0].value =='student'){
({
title: 'Login successfully',
icon: 'success',
duration: 1000
})
('sessionid', ['Set-Cookie']); //Save Cookie to Storage
}
} else {
({
title: 'Login failed',
icon: 'none',
duration: 2000
})
}
},
When making a request for the page later, add the value of the Set-Cookie you stored in the request header
({ url: 'https://xxxx/examResult/selectWxListStudentStudyStatistic',
method: 'post',
header: {
'content-type': 'application/x-www-form-urlencoded',//Solve the request for data 'cookie': ("sessionid")//Read sessionid, pass it into the background as a cookie and use PHPSESSID as session_id },
success: function (res) {
();// Remove loading },
fail: function (e) {
({
title: 'The server has an error',
icon: 'none',
duration: 2000
})
}
})
