分享朋友圈、qq等思路及代码

第一步：获取access_token
获取
/*
 * 获取基础access_token
 */
public static function getAccess_token(){
    $obj = new self();
    $accesstoken = Yii::$app->redis->get('wechatAccessToken');
    if ($accesstoken) {
        return $accesstoken;
    } else {
        $url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$obj->appid.'&secret='.$obj->appsecret;
        $response = Curl::curlGet($url);
        $data = json_decode($response,true);
        Yii::$app->redis->set('wechatAccessToken', $data['access_token']);
        Yii::$app->redis->expire('wechatAccessToken', 7000);
        return $data['access_token'];
    }
}
第二步获取ticket ，存入redis中

/*
 * 获取jsapi_ticket
 */
public static function getJsapi_ticket(){
    $jsapi_ticket = Yii::$app->redis->get('jsapi_ticket');
    if ($jsapi_ticket) {
        return $jsapi_ticket;
    } else {
        $access_token = self::getAccess_token();
        $url = 'https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token='.$access_token.'&type=jsapi';
        $response = Curl::curlGet($url);
        $data = json_decode($response,true);
        Yii::$app->redis->set('jsapi_ticket', $data['ticket']);
        Yii::$app->redis->expire('jsapi_ticket', 7000);
        return $data['ticket'];
    }
}

第三步：获取需要返回的签名

/*
 * 对jsapi_ticket签名
 */
public static function getSignatureByTicket($data){
    ksort($data);
    $str = '';
    foreach ($data as $k => $val){
        $str .= $k.'='.$val.'&';
    }
    $str = trim($str,'&');
    $signature = sha1($str);
    return $signature;
}

第四步 返回需要组装的数组

$data['noncestr'] = Common::getRandStr(8);
$data['jsapi_ticket'] = WeChat::getJsapi_ticket();
$data['timestamp'] = time();
$data['url'] = Yii::$app->request->hostInfo.Yii::$app->request->getUrl();
$JsJdk['signature'] = WeChat::getSignatureByTicket($data);
$JsJdk['timestamp'] = $data['timestamp'];
$JsJdk['noncestr'] = $data['noncestr'];
$JsJdk['appId'] = Yii::$app->params['wechat']['AppID'];

第五步获取 需要分享的参数

$share_config = array("title"=>'优惠券分享',"link"=>$data['url'],"imgUrl"=>'http://'.$_SERVER['HTTP_HOST'].'/application/images/fenxiang1.png',"desc"=>'分享代金券');
