微信auth授权验证类，在别人的基础上修改的，有用的上的参考下
<?php /** * 微信授权相关接口 * * */ class wechatauth { //高级功能-》开发者模式-》获取 private $app_id = 'wxa0c4*************'; private $app_secret = 'e095b6dc**********************'; /** * 获取微信授权链接 * * @param string $redirect_uri 跳转地址 * @param mixed $state 参数 */ public function get_authorize_url($redirect_uri = '', $state = '') { $redirect_uri = urlencode($redirect_uri); return "https://open.weixin.qq.com/connect/oauth2/authorize?appid={$this->app_id}&redirect_uri={$redirect_uri}&response_type=code&scope=snsapi_userinfo&state={$state}#wechat_redirect"; } /** * 获取授权token * * @param string $code 通过get_authorize_url获取到的code */ public function get_access_token($app_id = '', $app_secret = '', $code = '') { $token_url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid={$this->app_id}&secret={$this->app_secret}&code={$code}&grant_type=authorization_code"; $token_data = $this->http($token_url); if($token_data[0] == 200) { return json_decode($token_data[1], TRUE); } return FALSE; } /** * 获取授权后的微信用户信息 * * @param string $access_token * @param string $open_id */ public function get_user_info($access_token = '', $open_id = '') { if($access_token && $open_id) { $info_url = "https://api.weixin.qq.com/sns/userinfo?access_token={$access_token}&openid={$open_id}&lang=zh_CN"; $info_data = $this->http($info_url); if($info_data[0] == 200) { return json_decode($info_data[1], TRUE); } } return FALSE; } /** * 验证授权 * * @param string $access_token * @param string $open_id */ public function check_access_token($access_token = '', $open_id = '') { if($access_token && $open_id) { $info_url = "https://api.weixin.qq.com/sns/auth?access_token={$access_token}&openid={$open_id}&lang=zh_CN"; $info_data = $this->http($info_url); if($info_data[0] == 200) { return json_decode($info_data[1], TRUE); } } return FALSE; } //curl public function http($url, $method, $postfields = null, $headers = array(), $debug = false) { $ci = curl_init(); /* Curl settings */ curl_setopt($ci, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); curl_setopt($ci, CURLOPT_CONNECTTIMEOUT, 30); curl_setopt($ci, CURLOPT_TIMEOUT, 30); curl_setopt($ci, CURLOPT_RETURNTRANSFER, true); switch ($method) { case 'POST': curl_setopt($ci, CURLOPT_POST, true); if (!empty($postfields)) { curl_setopt($ci, CURLOPT_POSTFIELDS, $postfields); $this->postdata = $postfields; } break; } curl_setopt($ci, CURLOPT_URL, $url); curl_setopt($ci, CURLOPT_HTTPHEADER, $headers); curl_setopt($ci, CURLINFO_HEADER_OUT, true); $response = curl_exec($ci); $http_code = curl_getinfo($ci, CURLINFO_HTTP_CODE); if ($debug) { echo "=====post data======\r\n"; var_dump($postfields); echo '=====info=====' . "\r\n"; print_r(curl_getinfo($ci)); echo '=====$response=====' . "\r\n"; print_r($response); } curl_close($ci); return array($http_code, $response); } }放出输出的demo，有用的上的可以参考//微信认证链接 public function wxurl(){ import('MyClass.Wechatauth',APP_PATH); $Wechat = new wechatauth(); $token = session('token'); //查看是否已经授权 if (!empty($token)) { print_r($token); $state = $Wechat->check_access_token($token['access_token'],$token['openid']); //检验token是否可用(成功的信息："errcode":0,"errmsg":"ok") print_r($state); } $url = $Wechat->get_authorize_url('http://twx.vjiankang.org/wsite/test/wxrurl','1'); //此处链接授权后，会跳转到下方处理 echo '<a>授权</a>'; } //微信返回字符串 public function wxrurl(){ import('MyClass.Wechatauth',APP_PATH); $Wechat = new wechatauth(); print_r($_GET); //授权成功后跳转到此页面获取的信息 $token = $Wechat->get_access_token('','',$_GET['code']); //确认授权后会，根据返回的code获取token print_r($token); session('token',$token); //保存授权信息 $user_info = $Wechat->get_user_info($token['access_token'],$token['openid']); //获取用户信息 print_r($user_info); }需要注意的是，我们用于返回的url，需要在微信公众平台-》开发者-》auth认证里修改为同一域名下
