因为项目中很多地方都涉及到微信接口的调用 比如很多前台模块需要用到 后台模块也有少许调用 其他模块也可能会需要调用 为了让他们都能很方便的直接调用 我把他们独立成为一个模块 这个模块包含了基础的微信接口和微信jssdk
具体的设计请参考下面 当然如果有更好的建议可以共同交流
我先建立了一个新的模块叫Weixin 并在其下面建立了控制器BaseController 也就是一个微信类
这个微信基类 我是这样定义的
<?php /** *微信开发的公共类(不含支付 如需要可自行加入) * */ namespace Weixin\Controller; use Think\Controller; use Com\WechatAuth; use Com\Jssdk; class BaseController extends Controller { public $appId; public $appSecret; public $WechatAuth; public $jssdk; public function _initialize(){ $config = F(‘DB_CONFIG_DATA‘); //获取配置信息 if(!$config){ $config = api(‘Config/lists‘); F(‘DB_CONFIG_DATA‘,$config); } C($config); //添加配置 $this->appId = C(‘WEIXIN_CONFIG.appId‘); $this->appSecret = C(‘WEIXIN_CONFIG.appSecret‘); $this->WechatAuth = new WechatAuth($this->appId,$this->appSecret); $this->jssdk = new Jssdk($appId,$appSecret); //调用微信Jssdk // $this->signPackage = $this->jssdk->GetSignPackage(); }
?>
下面是我微信sdk包的部署目录结构供参考
这些部署好后 在任意模块中引入的方法是
$Weixin = new \Weixin\Controller\BaseController();
下面我用实例来讲述如何使用
1,获取用户信息(不管微信用户是否关注了公众号 下面代码大部分为注释内容 其实很少)
public function mytest () { $Weixin = new \Weixin\Controller\BaseController();
$domain = C(‘WEB_DOMAIN‘); $request_url = $_SERVER[‘REQUEST_URI‘]; $redirect_url = $domain.$request_url; if(!isset($_GET[‘code‘])){ header(‘Location: https://open.weixin.qq.com/connect/oauth2/authorize?appid=‘.$Weixin->appId.‘&redirect_uri=‘.$redirect_url.‘&response_type=code&scope=snsapi_base&state=1/‘); exit; } $code = $_GET[‘code‘]; $access_token_arr = $Weixin->WechatAuth ->getAccessToken(‘code‘,$code); //oauth2.0网页授权的access_token //$access_token_arr数据结构如下 /* Array ( [access_token] => OezXcEiiBSKSxW0eoylIeLrIQT6NoDaXZIUcW_1wOj_TwSQ_Jqp2CBj0RLBbgvBCkzyZ74E6066btMwNPj6JYaR_TPn9PH02FgR4APr7iOhihlYgosPEyDZIVJXduuvUj3ay5cVYpv_TDA3TBNvLiA [expires_in] => 7200 [refresh_token] => OezXcEiiBSKSxW0eoylIeLrIQT6NoDaXZIUcW_1wOj_TwSQ_Jqp2CBj0RLBbgvBCzJ6lw18Bb-cy9yUp2Tojmp48u_95jVHl1WTODEM0Z3yAPY8sORIlF0Gw8_99eEXsCagdc29djCjEWv2TovkPig [openid] => o0r2njtFSolnsaBoVP5MxjhNjUlg [scope] => snsapi_base )*/ $globals_access_token = $Weixin->WechatAuth->getAccessToken(); //全局access_token $userInfo = $Weixin->WechatAuth->userInfo($access_token_arr[‘openid‘]); //通过全局access_token获取用户基本信息 未关注是array(‘subscribe‘=>0,‘openid‘) if(!$userInfo[‘subscribe‘]){ //用户未关注 只能通过网页授权api获取用户信息 $data = array(); $data[‘access_token‘] = $access_token_arr[‘access_token‘]; $data[‘openid‘] = $access_token_arr[‘openid‘]; $userinfo = $Weixin->WechatAuth->getUserInfo($data); p($userinfo);//打印信息 /* Array( [openid] => o0r2njtFSolnsaBoVP5MxjhNjUlg [nickname] => 呼啦啦 [sex] => 1 [language] => zh_CN [city] => [province] => [country] => 赞比亚 [headimgurl] => http://wx.qlogo.cn/mmopen/rBgkzASpGRQLPXPDlEGmPoHl35qjwaA8s4WfOncETZm7kDGEVicEJZORzO73m7ib9Av7AK7icLrfl1nmhxGsglmzJRcnryNPy6T/0 [privilege] => Array ( ) ) */ }else{ //关注了公众号 直接返回用户信息 p($userInfo); //打印信息 /* Array( [subscribe] => 1 [openid] => o0r2njtFSolnsaBoVP5MxjhNjUlg [nickname] => 呼啦啦 [sex] => 1 [language] => zh_CN [city] => [province] => [country] => 赞比亚 [headimgurl] => http://wx.qlogo.cn/mmopen/rBgkzASpGRQLPXPDlEGmPoHl35qjwaA8s4WfOncETZm7kDGEVicEJZORzO73m7ib9Av7AK7icLrfl1nmhxGsglmzJRcnryNPy6T/0 [subscribe_time] => 1427793013 [remark] => ) */ } }
由于微信开发自身机制的原因,在这里要说明的是,thinkphp官方给的wechatAuth包 中并没有对access_token进行缓存,还需要进行适当修改 下面仅以wechatAuth.class.php文件修改为例说明 (网页授权的token, jssdk中的ticket 也要做类似如下的缓存,在此就不一一说明了)
