微信授权登陆获取用户信息
根据微信api和自己实际项目开发；
1 public function getuserinfo() 2 { 3 if (isset($_GET['code'])) { 4 //获取access_token openid refresh_token 5 $url1 = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid=' . $this->appid . '&secret=' . $this->secret . '&code=' . $_GET['code'] . '&grant_type=authorization_code'; 6 $result_access_token = $this->http_curl($url1); //主要返回取access_token 和 openid 7 $arr = json_decode($result_access_token, true); //数组 8 //验证access_token是否有效 9 $url_fresh_verification = 'https://api.weixin.qq.com/sns/auth?access_token=' . $arr['access_token'] . '&openid=' . $arr['openid'] . ''; 10 $refresh_token_istrue = $this->http_curl($url_fresh_verification); 11 $refresh_token_istrue = json_decode($refresh_token_istrue, true); 12 if ($refresh_token_istrue['errcode'] != 0) { 13 //3.0 重新刷新access_token 14 $url_get_new_access_token = 'https://api.weixin.qq.com/sns/oauth2/refresh_token?appid=wxeb8d4ef8686310eb&grant_type=refresh_token&refresh_token=' . $arr['refresh_token'] . ''; 15 $new_access_token = $this->http_curl($url_get_new_access_token); 16 $obj = json_decode($new_access_token); 17 //重新取得access_token 18 $arr['access_token'] = $obj->access_token; 19 } 20 // 获取用户信息 21 if (count($arr) > 2) { 22 $url_userinfo = 'https://api.weixin.qq.com/sns/userinfo?access_token=' . $arr['access_token'] . '&openid=' . $arr['openid'] . '&lang=zh_CN'; 23 $result_userinfo = $this->http_curl($url_userinfo); 24 //dump(json_decode($result_userinfo,true)); 25 } else { 26 echo json_encode($arr); 27 } 28 } else { 29 echo "授权失败"; 30 } 31 }
curl会话机制执行url
1 public function http_curl($url){ 2 $ch=curl_init();//开启会话机制 3 curl_setopt($ch,CURLOPT_URL,$url); 4 curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); //获取数据返回 5 curl_setopt($ch,CURLOPT_BINARYTRANSFER,true); //启用 6 $result=curl_exec($ch); //执行 7 curl_close($ch); //关闭会话机制 8 return json_decode($result,true); //true 返回数组，默认返回对象 9 }
