PHP端处理TP3.2框架
一：类名：
namespace Home\Controller;use Think\Controller;use app\common\Curl;class ParentController extends Controller{ public function __construct(){ parent::__construct(); $this->appId = '你的appid'; $this->appSecret = '你的appSecret'; $openid = session('openid'); // session("openid",'ogC7U1XRM3ZOqjLZ99O2coJjYsrU'); if(!$openid){ $this->get_openid(); } }
二：方法：
给客户端返回必要微信参数：
/** * 给客户端返回必要微信参数 * @Author TGHan * @DateTime 2018-04-26 * @return [type] [description] */ public function modifyinfor() { $jsapiTicket = $this->getJsApiTicket(); // 注意 URL 一定要动态获取，不能 hardcode. $protocol = (!empty($_SERVER[<strong style="color:transparent">￥本文来源gaodai#ma#com搞@@代~&码网^</strong><small>搞gaodaima代码</small>'HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://"; $url = "$protocol$_SERVER[HTTP_HOST]$_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 ); $this->assign('signPackage',$signPackage); $this->display(); } public function createNonceStr($length = 16) { $chars ="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; $str = ""; for ($i = 0; $i < $length; $i++) { $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1); } return $str; } public 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(); // 如果是企业号用以下 URL 获取 ticket // $url = "https://qyapi.weixin.qq.com/cgi-bin/get_jsapi_ticket?access_token=$accessToken"; $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken"; $res = json_decode($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; } public 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()) { // 如果是企业号用以下URL获取access_token // $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret"; $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret"; $res = json_decode($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 $access_token; } public function httpGet($url) { $curl = curl_init(); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_TIMEOUT, 500); // 为保证第三方服务器与微信服务器之间数据传输的安全性，所有微信接口采用https方式调用，必须使用下面2行代码打开ssl安全校验。 // 如果在部署过程中代码在此处验证失败，请到 http://curl.haxx.se/ca/cacert.pem 下载新的证书判别文件。 curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true); curl_setopt($curl, CURLOPT_URL, $url); $res = curl_exec($curl); curl_close($curl); return $res; }
