1. 當前商城(uid標識)受權第三方開發平臺.

第三方平臺受權

安裝easywechat4

$ composer require overtrue/wechat:~4.0 -vvv

引用

use EasyWeChat\Factory;

建立一個跳轉到微信掃二維碼受權頁面

/**
 * 開發平臺受權跳轉
 *
 * @return void
 */
public function accessView(){
    // 
    $uid = Request()->route('uid' , 0);
    $url = 'http://qgcloud.capsui.com/public/index/wxopen/config?uid=' . $uid;
    $this->assign('url' , $url);
    return $this->fetch();
}

跳轉方法(爲何我不寫到上一個方法呢 由於微信要求同一個地址)

/**
 * 開發平臺跳轉受權掃碼頁
 *
 * @return void
 */
public function config(){
    $uid = Request()->get('uid' , 0);
    $config = [
        'app_id'   => '開放平臺第三方平臺 APPID',
        'secret'   => '開放平臺第三方平臺 Secret',
        'token'    => '開放平臺第三方平臺 Token',
        'aes_key'  => '開放平臺第三方平臺 AES Key'
    ];
    $openPlatform = Factory::openPlatform($config);
    
    $url = $openPlatform->getPreAuthorizationUrl('http://qgcloud.capsui.com/public/index/wxopen/wxcallback?uid=' . $uid);

    $this->redirect($url);
}

受權回調(注意:掃碼確認受權後他第一次回調不會帶uid參數,)

引入 
use EasyWeChat\OpenPlatform\Server\Guard;

/**
 * 開發平臺受權回調
 *
 * @return void
 */
public function wxcallback(){
    // 這個表是記錄受權成功的
    //$Wxpublic   = new Wxpublic;
    // 這個表是記錄受權成功後傳過來所屬uid商城綁定appid
    //$ShopConfig = new ShopConfig;

    $get = Request()->param();
    
    $config = [
        'app_id'   => '開放平臺第三方平臺 APPID',
        'secret'   => '開放平臺第三方平臺 Secret',
        'token'    => '開放平臺第三方平臺 Token',
        'aes_key'  => '開放平臺第三方平臺 AES Key'
    ];
    $openPlatform = Factory::openPlatform($config);
    $server       = $openPlatform->server;

    
    // 處理受權成功事件-第一次回調
    // 閉包方法!裏面調用外面的方法請在use裏面填寫
    $server->push(function ($message) use ($openPlatform /*, $Wxpublic*/) {
        
        $authCode = $message['AuthorizationCode'];
        $res      = $openPlatform->handleAuthorize($authCode);

        if($res['authorization_info']['authorizer_refresh_token']){
            //受權成功記錄到數據庫
            //$Wxpublic->insert(['appid' => $res['authorization_info']['authorizer_appid'] , 'createtime' => time()]);
        }

    }, Guard::EVENT_AUTHORIZED);

    // 處理受權取消事件-第一次回調
    // 閉包方法!裏面調用外面的方法請在use裏面填寫
    $server->push(function ($message) use(/*$Wxpublic , $ShopConfig*/) {
        //處理數據庫邏輯
        //$Wxpublic::appid($message['AppId'])->delete();
        //$ShopConfig::appid($message['AppId'])->update(['token' => '']);
    }, Guard::EVENT_UNAUTHORIZED);
    
    // 第二次回調會帶一個受權code和自定義參數商城id(uid)
    if(isset($get['auth_code']) && isset($get['uid'])){
        
        $res      = $openPlatform->handleAuthorize($get['auth_code']);
        $appid    = $res['authorization_info']['authorizer_appid'];
        //數據庫邏輯
        //$isConfig = $Wxpublic::appid($appid)->count();
        
        //if($isConfig){
        //$add = $ShopConfig->where('uid' , $get['uid'])->update(['token' => $appid]);
        //}
    }

    return $server->serve();
}

第三方平臺 網頁受權&微信JSSDK初始化簽名生成

/**
 * 網頁受權調起
 *
 * @return void
 */
public function htmlAccess(){
    $appid = Request()->get('appid' , 0);
    
    $config = [
        'app_id'   => '開放平臺第三方平臺 APPID',
        'secret'   => '開放平臺第三方平臺 Secret',
        'token'    => '開放平臺第三方平臺 Token',
        'aes_key'  => '開放平臺第三方平臺 AES Key'
    ];
    $openPlatform = Factory::openPlatform($config);
    $data         = $openPlatform->getAuthorizer($appid);
    $appid        = $data['authorization_info']['authorizer_appid'];
    $refreshToken = $data['authorization_info']['authorizer_refresh_token'];

    $officialAccount = $openPlatform->officialAccount($appid , $refreshToken);
    $oauth           = $officialAccount->oauth;
    
    // 回調受權地址
    $url      = "http://qgcloud.capsui.com/public/index/wxopen/callbackOpenid";
    $response = $officialAccount->oauth->scopes(['snsapi_userinfo'])->redirect($url)->send();

}

網頁受權回調方法

/**
