Discuz Passport pass integrated notes

It's too simple, but it takes a long time to remember. It's a waste of half an hour to find information. I have a deep understanding that good memory is not as bad as writing !! Paste the passport text block today to prevent future forgetting !! Remember, it takes time to find the information you need online !!!!!!


Passport pass integrationArticle 1: Principles of Integration

Please note: the possible consequences of failed integration ----- dz forum cannot be logged on, cannot be managed
Solution:
Step 1: Go to the dz database table cdb_settings and find the following rows and change them
Setting.gif(4.3 KB)

Step 2: delete the dz installation directory/forumdata/cache/cache_settings.php
Step 3: Access the Forum again


Login and registration Integration Process
The user submits the account password information from the login or registry ticket ==>
The Main Station Program checks user login or registration. If the registration succeeds (a new user needs to be generated for registration), then ==>
Set the cookie or session of the main site itself ==>
Url transfer the returned address forward and encoded user information and other information to dz/api/passport. php

Before integration Please carefully read the official passport Technical Documentation: http://www.discuz.net/usersguide/advanced_passport.htmCopy content to clipboardCode:<? Php
// Save this document as login. php
// First copy the encryption and decryption functions in the interface technical document
// To prevent code from being too messy, I copied it to the end of the document.
// Assume that the UserName field is UserName, the password field is Pwd, And the Email field is Email.
// The registration page implementation method is similar. You can implement it on your own. Add QQ to question: 2666556
