微信公众号、小程序、APP授权

微信公众号授权 示例

// 导入命名空间
use Namesfang\WeChat\OAuth\Log\Logger;
use Namesfang\WeChat\OAuth\Bundle\Code;
use Namesfang\WeChat\OAuth\Bundle\CodeOption;
use Namesfang\WeChat\OAuth\Bundle\AccessToken;
use Namesfang\WeChat\OAuth\Bundle\AccessTokenOption;
use Namesfang\WeChat\OAuth\Bundle\UserInfo;
use Namesfang\WeChat\OAuth\Bundle\UserInfoOption;

// +-----------------------------------------------------------
// | 日志记录
// | 自行封装需要实现 LoggerInterface 接口类
// +-----------------------------------------------------------
$logger = new Logger(LOG_PATH, true);

// +-----------------------------------------------------------
// | 第1步
// | 获得CODE
// +-----------------------------------------------------------

// 参数配置方式1
 /*
 $option = new CodeOption([
 'appid'=> 'wx1111111111111111',
 'scope'=> 'snsapi_userinfo',
 'state'=> 'xxx',
 'redirect_uri'=> '',
 ]);
 */

// 参数配置方式2
$option = new CodeOption();
$option->setAppId('wx1111111111111111');
$option->setRedirectUri('http://cli.life/auth/wechat');
$option->setScope($option::SCOPE_SNSAPI_USERINFO);
$option->setState('xxx');

// 实例化 用于获取code也可自行组装URL
$code = new Code($option, $logger);

// 生成跳转到微信平台授权URL
// 从微信平台跳转回来会携带 code和state
$url = $code->makeUrl();

// 打印接口返回信息
$logger->print($url, true);

// 前台展示授权按钮
// $logger->print("<a href=\"{$url}\">授权</a>", true);

// +-----------------------------------------------------------
// | 第2步
// | 获得 ACCESS-TOKEN和OPENID
// +-----------------------------------------------------------

// 配置参数
/*
 $option = new AccessTokenOption([
 'appid'=> '',
 'secret'=> '',
 'code'=> '',
 ]);
 */

$option->setCode('code');

$token = new AccessToken($option, $logger);

$result = $token->request();

$logger->print($result->original, true);

$logger->print($result->openid);

// +-----------------------------------------------------------
// | 第3步
// | 获得 授权信息
// +-----------------------------------------------------------
/*
 $option = new UserInfoOption([
 'openid'=> '',
 'access_token'=> '',
 'lang'=> 'zh_CN'
 ]);
 */

// | 自行封装需要实现 LoggerInterface 接口类
// +-----------------------------------------------------------
$logger = new Logger(LOG_PATH, true);

// +-----------------------------------------------------------
// | 获得登录信息
// +-----------------------------------------------------------
// 配置参数
/*
$option = new AccessTokenOption([

//
// $with_miniprogram 为 true 
// 程序自动差异处理
//
$result = $token->request(true);

$logger->print($result->original, true);

$logger->print($result->openid);

// +-----------------------------------------------------------
// | 解密小程序敏感数据
// +-----------------------------------------------------------
//
// 将 wx.getUserInfo 回调函数返回的参数分别传入
//

// 解密成功

刷新 ACCESS TOKEN

// +-----------------------------------------------------------
// | 刷新 token 仅APP和公众号可用
// +-----------------------------------------------------------
/*

*/

校验 ACCESS TOKEN

// +-----------------------------------------------------------
// | 校验 token 仅APP和公众号可用
// +-----------------------------------------------------------

// 将第2步获得的 refresh_token 自行存储
// 在需要的时刷新

加密

// 导入命名空间
use Namesfang\WeChat\OAuth\Util\Encrypt;

// 加密成功

    print_r($encrypt->key);
    print_r($encrypt->iv);
    print_r($encrypt->result);
} else {
    echo $encrypt->error;
}

解密

// 导入命名空间
use Namesfang\WeChat\OAuth\Util\Decrypt;

$decrypt = new Decrypt();

// 解密成功
if($decrypt->handle($encrypt->data, $encrypt->key, $encrypt->iv)) {
    $logger->print($decrypt->result);
