基于PHP方法，微信公众号小程序获取code,access_token,openid,用户信息

//发起获得code值链接 public function doPageGetcode() { $appid = 'yourappid';//修改你的appid if (!$appid) { return $this->result(10008, '参数错误', ''); } //这里的$redirect_uri地址需要http://,跳转对于登录doPageOpenid方法,在微信公众号上面也有添加这个域名http://wx.owen.com/ $redirect_uri = urlencode("http://wx.owen.com/doPageOpenid"); $url = "

public function httpRequest($url, $data = null)
  {
     $curl = curl_init();
     curl\_setopt($curl, CURLOPT\_URL, $url);
     curl\_setopt($curl, CURLOPT\_SSL_VERIFYPEER, FALSE);
     curl\_setopt($curl, CURLOPT\_SSL_VERIFYHOST, FALSE);
     if (!empty($data)) {
        curl\_setopt($curl, CURLOPT\_POST, 1);
        curl\_setopt($curl, CURLOPT\_POSTFIELDS, $data);
     }
     curl\_setopt($curl, CURLOPT\_RETURNTRANSFER, 1);
     $output = curl_exec($curl);
     curl_close($curl);
     return $output;
  }

  //获取用户信息和注册
  public function doPageOpenid()
  {
     $appid = "yourappid";//修改你的appid
     $secret = "yourappsecret";//修改你的appsecret
     $code = $_GPC\["code"\];

     //小程序

// $url = "

https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $appid . "&secret=" . $secret; //公众号// 获得当前用户的Openid和access_token $url = '

$res = $this->httpRequest($url); $jsoninfo = json_decode($res, true); $access\_token = $jsoninfo\["access\_token"\]; $openid = $jsoninfo\["openid"\]; // // 获得所有关注用户的Openid // $url = "

https://api.weixin.qq.com/cgi-bin/user/get?access_token=" . $access_token; // $result = $this->httpRequest($url); // $jsoninfo = json_decode($result, true); // $openid = $jsoninfo["data"]["openid"][0];

if ($access_token && $openid) {
        $url = "https://api.weixin.qq.com/sns/userinfo?access\_token=" . $access\_token . "&openid=" . $openid . "&lang=zh_CN";
        $output = $this->httpRequest($url);

//用户信息数组jsonUserinfo $jsonUserinfo = json_decode($output, true); return $this->result(0, '登录成功', $jsonUserinfo); } } }

Buy me a cup of coffee :)
