PHP如何获取微信用户的 openid 和基本信息

基本配置

public functiongetcode(){

    //基本配置    $appid='';    $redirect_uri=urlencode("http://授权回调页面域名/plugs/task/getuserinfo");    $url="https://open.weixin.qq.com/connect/oauth2/authorize?appid=".$appid."&redirect_uri=".$redirect_uri."&response_type=code&scope=snsapi_userinfo&state=1#wechat_redirect";    header("location:".$url);}

获取信息

public function getuserinfo(){

    $appid  = "";    $secret = "";    //这里获取到了code    $code   = $_GET['code'];    //第一步:取得openid    $oauth2Url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=".$appid."&secret=".$secret."&code=".$code."&grant_type=authorization_code";    $oauth2 = $this->http_curl($oauth2Url);    //accestoken    $access_token = $oauth2["access_token"];    //openid    $openid = $oauth2['openid'];    //第二步:根据全局access_token和openid查询用户信息    $get_user_info_url = "https://api.weixin.qq.com/sns/userinfo?access_token=".$access_token."&openid=".$openid."&lang=zh_CN";    $userinfo = $this->http_curl($get_user_info_url);    dump($userinfo);
    //打印用户信息}
curl请求
function http_curl($url){    //用curl传参    $ch = curl_init();    curl_setopt($ch, CURLOPT_URL, $url);    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);    //关闭ssl验证    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);    curl_setopt($ch,CURLOPT_HEADER, 0);    $output = curl_exec($ch);    curl_close($ch);    return json_decode($output, true);}
