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,如图所示
3、PHP分享接口类
这里不多说,直接上代码
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#111
这里我以自定义“分享给朋友”及“分享到QQ”按钮的分享内容(1.4.0)接口为例
