微信分享对接php项目:

做微信分享开发要注意所有的JS接口只能在公众号绑定的域名下调用,公众号开发者需要先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”

1,Jssdk类包的引入Jssdk.class.php生成注册微信官方分享按钮的权限参数,代码如下:

class Jssdk {
  private $appId;
  private $appSecret;

  public function __construct($appId, $appSecret) {
    $this->appId = $appId;
    $this->appSecret = $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=$nonceStr&timestamp=$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();
      // 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;
  }

  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()) {
      // 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;
  }

  private 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;
  }
}

 

2,引入微信官方的js demo.html

程序示例:

<?php
class DemoAction extends Action{

    public function WxShare(){
        /* 微信分享前置配置数据 */
        import(‘@.ORG.Jssdk‘);
        $WxShare = new Jssdk(C(‘new_appid‘),C(‘appsecret‘));
        $this->Share = $WxShare->getSignPackage();//生成注册微信分享按钮参数
    }
}
?>

模板输出示例:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Strict//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>微信分享Demo</title>
<script type="text/javascript" src="./Tpl/js/weixin.js"></script>
<script>
/* 注册微信分享按钮权限参数 */
    var WxShareConfig = {
            "AppID":"{$Share.appId}",
            "TimeStamp":"{$Share.timestamp}",
            "NonceStr":"{$Share.nonceStr}",
            "Signature":"{$Share.signature}",
    }
/* 分享数据参数 */
    window.shareData = {  
            "moduleName":"Store",
            "moduleID":"{$product[‘id‘]}",
            "imgUrl": "{$product[‘logourl‘]}", 
            "timeLineLink": "{:C(‘site_url‘) .  U(‘Store/product‘,array(‘token‘ => $_GET[‘token‘],‘id‘=>$product[‘id‘], ‘twid‘ => $mytwid))}",
            "sendFriendLink": "{:C(‘site_url‘) .  U(‘Store/product‘,array(‘token‘ => $_GET[‘token‘],‘id‘=>$product[‘id‘], ‘twid‘ => $mytwid))}",
            "weiboLink": "{:C(‘site_url‘) .  U(‘Store/product‘,array(‘token‘ => $_GET[‘token‘],‘id‘=>$product[‘id‘], ‘twid‘ => $mytwid))}",
            "tTitle": "{$metaTitle}",
            "tContent": "{$metaTitle}"
        };
</script>
<script type="text/javascript" src="./Tpl/js/wxshare.js"></script>
<script>
/* 分享成功处理的业务逻辑 */
    function shareSuccess(){
        $.post("U(‘Doaction/activity‘)",function (data) {
            alert(data.msg);
        },"json");
    }
</script>
</head>
<body>

</body>
</html>

3,wxshare.js引入demo.html页面处理分享事件(PS:程序所需要的js 传送门 解压密码:http://www.bieanju.com/)

4,根据3的返回状态进行业务逻辑处理
