**開發之前配置篇：** 一、登陸公眾號平臺(https://mp.weixin.qq.com),點擊設置-》公眾號設置-》功能設置-》JS接口安全域名（這里設置你網站的根域名），主意要將下載的文件放到你的網絡根域名設置的路徑下，不然會提示設置不成功。二、登陸公眾號平臺(https://mp.weixin.qq.com),點擊設置-》公眾號設置-》功能設置-》網頁授權域名（這里設置你網站的根域名），作用是為了獲取微信服務器的code，說明白一點就是微信的驗證。三、登陸公眾號平臺(https://mp.weixin.qq.com),點擊微信支付-》開發配置-》支付授權目錄（這里面要設置到你要訪問具體方法的那個控制器，并且以反斜杠結束，如果是做分享，這步可以跳過）。四、設置Api密匙：登陸商戶平臺(https://pay.weixin.qq.com/),賬戶中心-》API安全（這里要下載安裝操作證書，才可以設置Api密匙）四、 **開發之前獲取參數篇：** 一、獲取原始Id：登陸公眾號平臺(https://mp.weixin.qq.com),點擊設置-》公眾號設置-》賬號詳情，拉到底就見這個值。二、獲取商戶號：登陸公眾號平臺(https://mp.weixin.qq.com),點擊微信支付-》商戶信息，這里就可見這個值。三、應用Id:登陸公眾號平臺(https://mp.weixin.qq.com),點擊開發-》基本配置，即可看見這個值四、應用密匙：登陸公眾號平臺(https://mp.weixin.qq.com),點擊開發-》基本配置，即可看見這個值（需要短信驗證和授權）五、Api密匙：登陸商戶平臺(https://pay.weixin.qq.com/),賬戶中心-》API安全（這里要下載安裝操作證書，才可以查看Api密匙，同時還要下載這里面的操作證書到你的網站中，文件夾名稱一般為cert） **準備之后開發微信分享后臺代碼篇** 只需調用getSignPackage傳入公眾號配置信息，和緩存的信息即可。這里特別要主要分享的頁面必須是和我們現在當前頁面的URL是一致的，不然簽名會出現錯誤 public function getSignPackage($config,$weixinConfig) { $jsapiTicket = $this->getJsApiTicket($config,$weixinConfig); // 注意 URL 一定要動態獲取，不能 hardcode. $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ?
