我用TP5開發(fā)微信小程序登錄接口的時候，在校驗簽名signature那遇到了個坑，一直校驗失敗，找了很久才發(fā)現(xiàn)

原因是：tp的input方法會自動轉(zhuǎn)移html字符，比如’”’轉(zhuǎn)成了 &quote; ,所以導(dǎo)致了失敗：

本來的rawData

{"nickName":"小小黑","gender":1,"language":"en","city":"Zhanjiang","province":"Guangdong","country":"CN","avatarUrl":"http://wx./mmopen/vi_32/iaFp2syscJNYgalastnQ3bnYt2l4cURSX7p7CeZ7SkNLa32yqBHsXITPibqrJl7z6mYYIibmCLlwtoOwCp0nMibIgA/0"}WYrl3b8xiPuJlOnY/zCXdw==

TP中input方法過濾過的rawData

{"nickName":"小小黑","gender":1,"language":"en","city":"Zhanjiang","province":"Guangdong","country":"CN","avatarUrl":"http://wx./mmopen/vi_32/iaFp2syscJNYgalastnQ3bnYt2l4cURSX7p7CeZ7SkNLa32yqBHsXITPibqrJl7z6mYYIibmCLlwtoOwCp0nMibIgA/0"}WYrl3b8xiPuJlOnY/zCXdw==

所以校驗方法需要這樣寫：

$signature2 = sha1(htmlspecialchars_decode($rawData) . $session_key);

if ($signature2 !== $signature) return ret_message("signNotMatch");

后續(xù)會給一個完整的登錄流程代碼（前端+ThinkPHP5.0）
