index.php 是准备授权的页面 ,我在这打印了下获取到的用户数据
require_once("./function.php"); $url = ‘http://‘.$_SERVER[‘HTTP_HOST‘].$_SERVER[‘REQUEST_URI‘].‘?pid=x‘; $getuserinfo = getuserinfo($url); print_r($getuserinfo);
function.php代码如下
function getuserinfo($url){ require_once("./oauth.php"); $wechat = new Wechat(); if(isset($_GET[‘param‘]) && isset($_GET[‘code‘])){ $get = $_GET[‘param‘]; $code = $_GET[‘code‘]; if($get==‘access_token‘ && !empty($code)){ $json = $wechat->get_access_token($code); return $json; } }else{ $wechat->get_authorize_url($url.‘¶m=access_token‘,‘STATE‘); } }
auth.php代码如下
<?php class Wechat { //高级功能-》开发者模式-》获取 private $app_id = ‘xxxxx‘;//appid private $app_secret = ‘xxxxx‘;//app密匙 /** * 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); $url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid={$this->app_id}&redirect_uri={$redirect_uri}&response_type=code&scope=snsapi_base&state={$state}#wechat_redirect"; echo "<script language=‘javascript‘ type=‘text/javascript‘>"; echo "window.location.href=‘$url‘"; echo "</script>"; } /** * 获取授权token * * @param string $code 通过get_authorize_url获取到的code */ public function get_access_token($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; } public function http($url, $method=‘post‘, $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); } } ?>
