背景
在微信分享开发的时候我们通常的流程是
<"jssdk.php"; $jssdk = new JSSDK("yourAppID", "yourAppSecret"); $signPackage = $jssdk->GetSignPackage(); "en"> <head> <meta charset="UTF-8"> <title>微信分享</title> </head> <body> </body> <script src="/UploadFiles/2021-04-02/jweixin-1.0.0.js">http://res.wx.qq.com/open/js/jweixin-1.0.0.js 然后就可以写分享的函数了,他们的依赖关系是wx.config 需要js库和config内部的参数,分享依赖wx.config
所以最重要的就把php的配置参数分离出来单独获取即可解决方案
将获取配置参数的PHP写作为接口,在js里使用ajax调用,获取参数并转换为对象,再通过回调函数将ajax获取的参数塞到wx.config中代码结构及功能
- index.html 页面入口
- weixin.php 服务器端获取配置参数
- configdata.php将配置转为借口输出
- getconfig.js 用ajax获取configdata.php的数据
- share.js 分享回调函
- webpack.config.js webpack配置文件
- index.js 打包后最终html调用js文件
index.html html静态文件
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>静态页面微信分享测试</title> </head> <body> <script src="/UploadFiles/2021-04-02/jweixin-1.0.0.js">configdata.php 后台获取配置的参数 注意url要写上自己被分享的页面url不然会报invalid signature错误
<"http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; $timestamp = time(); $nonceStr = $this->createNonceStr(); // 这里参数的顺序要按照 key 值 ASCII 码升序排序 $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr×tamp=$timestamp&url=$url"; $signature = sha1($string); $signPackage = array( "appId" => $this->appId, "nonceStr" => $nonceStr, "timestamp" => $timestamp, "url" => $url, "signature" => $signature, "rawString" => $string ); return $signPackage; } private function createNonceStr($length = 16) { $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; $str = ""; for ($i = 0; $i < $length; $i++) { $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1); } return $str; } private function getJsApiTicket() { // jsapi_ticket 应该全局存储与更新,以下代码以写入到文件中做示例 $data = json_decode(file_get_contents("jsapi_ticket.json")); if ($data->expire_time < time()) { $accessToken = $this->getAccessToken(); $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket"; $res = json_decode($this->httpGet($url)); $ticket = $res->ticket; if ($ticket) { $data->expire_time = time() + 7000; $data->jsapi_ticket = $ticket; $fp = fopen("jsapi_ticket.json", "w"); fwrite($fp, json_encode($data)); fclose($fp); } } else { $ticket = $data->jsapi_ticket; } return $ticket; } private function getAccessToken() { // access_token 应该全局存储与更新,以下代码以写入到文件中做示例 $data = json_decode(file_get_contents("access_token.json")); if ($data->expire_time < time()) { $url = "https://api.weixin.qq.com/cgi-bin/token"; $res = json_decode($this->httpGet($url)); $access_token = $res->access_token; if ($access_token) { $data->expire_time = time() + 7000; $data->access_token = $access_token; $fp = fopen("access_token.json", "w"); fwrite($fp, json_encode($data)); fclose($fp); } } else { $access_token = $data->access_token; } return $access_token; } private function httpGet($url) { $curl = curl_init(); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_TIMEOUT, 500); curl_setopt($curl, CURLOPT_URL, $url); $res = curl_exec($curl); curl_close($curl); return $res; } }weixin.php 将配置参数格式化输出
