以下文章只是講述我做這個東西的一個原理,主要實現(xiàn)是采用主站的認證來實現(xiàn)本站點的登陸,論壇采用隱式的密碼認證方式;如果想要了解更多,可以聯(lián)系我caijiche@gmail.com;這是www.caijiche.com用于oauth的原理。發(fā)出來和大家一起分享!
將functions.php中的函數(shù)page_header中的數(shù)組中“U_REGISTER”的值改成“http://www.caijiche.com/reg”
六、更改忘記密碼鏈接:將functions.php中的函數(shù)page_header中的數(shù)組中“ U_SEND_PASSWORD ”的值改成“http://www.caijiche.com/getpwd”
