PHP实现微信自定义的方式

PHP实现微信自定义的方式，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

要制作微信接口分享功能，前期需要注册一个公众号，并认证通过，只有这样才能实现接口制作。

下面我一步步给大家做介绍

1、公众号开发信息配置

在开发分享接口之前需要先配置公众平台配置信息，如下图所示：点击"开发-基本信息"，可以看到公众号开发信息，在开发者秘钥哪里点击"开启"，配置自己的秘钥信息，配置成功后，保存开发者ID(AppID)和开发者密码(AppSecret)

2、配置JS接口安全域名

点击"设置与开发--公众号设置"，点击JS接口安全域名后面的设置，按照要求添加js安全域名。

3、PHP分享接口类

class wechatClass {     public $AppID;     public $AppSecret;     public $redirect_uri;     public $DbSy;     public $dump_url;     public $scope;     public function __construct()     {         parent::__construct();         $this->AppID = "开发者密码(AppSecret)";         $this->AppSecret = "开发者密码(AppSecret)";     }     public function getSignPackage() {         $jsapiTicket = $this->getJsApiTicket();         // 注意 URL 一定要动态获取，不能 hardcode.         $protocol = (!empty($_SERVER['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);         // var_dump($signature);die;         $signPackage = array(             "appId"     => $this->AppID,             "nonceStr"  => $nonceStr,             "timestamp" => $timestamp,             "url"       => $url,             "signature" => $signature,             "rawString" => $string         );         return $signPackage;     }     public function createNonceStr($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         //echo $_SERVER['DOCUMENT_ROOT'];         $data = json_decode(file_get_contents($_SERVER['DOCUMENT_ROOT']."/static/yejuzhi/js/access_token.json"));         // var_dump($data->expire_time);die;         if ($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;                 $fp = fopen($_SERVER['DOCUMENT_ROOT']."/static/yejuzhi/js/access_token.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         $data = json_decode(file_get_contents($_SERVER['DOCUMENT_ROOT']."/static/yejuzhi/js/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;                 $fp = fopen($_SERVER['DOCUMENT_ROOT']."/static/yejuzhi/js/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($curl, CURLOPT_TIMEOUT, 500);         curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);         curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);         curl_setopt($curl, CURLOPT_URL, $url);         $res = curl_exec($curl);         curl_close($curl);         return $res;     } }

4、PHP文件配置

这里我是以TP5.1框架写的，大家可以自行设置

$wx = new WeChatClass();$sign = $wx->getSignPackage();$this->assign('sign',$sign);

5、前端HTML代码

前端HTML代码请参考开发文档：https://developers.weixin.qq.com/doc/offiaccount/OA_Web_Apps/JS-SDK.html#11
