公众号和小程序获取用户信息及获取手机号

公众号的获取用户信息
前端传code，后端根据code获取用户信息
代码：

$code = $this->request->param('code');//通过下面url获取access_t和 openid$url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid=' . getConfig('app_id') . '&secret=' . getConfig('app_secret') . '&code=' . $code . '&grant_type=authorization_code';//静默授权和非静默授权需要注意区分$data = json_decode($this->curl($url));if (empty($data)) {    apiResponse('0', 'code失效');}$access_token = $data->access_token;$openid = $data->openid;$get_user_info_url = "https://api.weixin.qq.com/sns/userinfo?access_token=$access_token&openid=$openid&lang=zh_CN";$userinfo = $this->getJson($get_user_info_url);//userinfo 里面就是用户信息了//引用的方法function curl($url) {    $curl = curl_init();    curl_setopt($curl, CURLOPT_URL, $url);    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);    $data = curl_exec($curl);    curl_close($curl);    return $data;}public function getJson($url) {    $ch = curl_init();    curl_setopt($ch, CURLOPT_URL, $url);    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);    $output = curl_exec($ch);    curl_close($ch);    return json_decode($output, true);}

小程序获取用户信息
前端传iv，encryptedData，code，然后后端根据code获取session_key，再利用session_key，encryptedData及iv来获取用户信息
注意：前端wx.login获取code和获取用户信息的顺序
代码：（用的easyWeChat）

use EasyWeChat\Factory;$this->wx_config = [           'app_id' => getConfig('app_id'),           'secret' => getConfig('app_secret'),           'response_type' => 'array',     ];$iv = $this->request->post('iv');    $encryptedData = $this->request->post('encryptedData');    $code = $this->request->post('code');    if (empty($iv) || empty($encryptedData) || empty($code)) {        apiResponse('0', "参数缺失");    }    $app = Factory::miniProgram($this->wx_config);    $session_keys = $app->auth->session($code);    if (empty($session_keys['session_key'])) {        apiResponse('0', $session_keys['errmsg']);    }    $session_key = $session_keys['session_key'];    $openid = $session_keys['openid'];    $data = $app->encryptor->decryptData($session_key, $iv, $encryptedData);    //data就是获取到的用户信息了

小程序获取用户手机号
前端传code，后端根据code获取用户手机号
代码：

   $access_token = $this->get_access_token();   $url = "https://api.weixin.qq.com/wxa/business/getuserphonenumber?access_token=" . $access_token;   $data = '{"code":"' . $params['code'] . '"}';   $result = curl_post($url, $data);   $result_arr = json_decode($result, true);   if ($result_arr['errcode'] == 0) {       apiResponse('0', '手机号获取失败');   }   //保存手机号   $result = Db::name('user')->where("uid", $user_id)->update(['mobile' => $result_arr['phone_info']['purePhoneNumber']]);//$result_arr['phone_info']['purePhoneNumber']是我想要的手机号  #获取access_token  public function get_access_token() {      $app_id = getConfig('app_id');      $secret = getConfig('app_secret');      $url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=' . $app_id . '&secret=' . $secret;      $result = file_get_contents($url);      $result = json_decode($result, true); //转为数组      return $result['access_token'];  }   function curlPost($url, $data){        $header = array(            'Content-Type: application/json; charset=utf-8',        );        $ch = curl_init();        curl_setopt($ch, CURLOPT_POST, 1);        curl_setopt($ch, CURLOPT_URL, $url);        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($ch, CURLOPT_HTTPHEADER, $header);        $response = curl_exec($ch);        curl_close($ch);        return $response;    }
