微信公众号怎样获取用户基本信息（含是否已关注）

没时间多写，直接上代码。

 

第一步：获取code，其中的链接可以通过任何方式生成，也可以用微信公众号菜单

<?php

 $APPID='wx7********6beb9db';  //填写高级调用功能的app id
 $appsecret='ce03f4********09c3b80ae6f1c270d5';  //填写高级调用功能的密钥
 $REDIRECT_URI='http://www.***.***:81/wechat/test/getcode_2.php';

 $scope='snsapi_base';
 //$scope='snsapi_userinfo';//需要授权
 $state=1;

 $url='https://open.weixin.qq.com/connect/oauth2/authorize?appid='.$APPID.'&redirect_uri='.urlencode($REDIRECT_URI).'&response_type=code&scope='.$scope.'&state='.$state.'#wechat_redirect';
 echo "url: ".$url;
 header("Location:".$url);
 ?>

 

 

 

第二步： 按步骤获取：access_token、用户openid、用户基本信息

<?php
 $APPID='wx7********6beb9db';  //填写高级调用功能的app id
 $APPSECRET='ce03f4********09c3b80ae6f1c270d5';  //填写高级调用功能的密钥

    $code = $_GET["code"];
    //$get_token_url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$APPID.'&secret='.$APPSECRET.'&code='.$code.'&grant_type=authorization_code';
    $get_token_url="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$APPID&secret=$APPSECRET";
    $res = post($get_token_url);
    $json_obj = json_decode($res,true);

    //根据openid和access_token查询用户信息
    $access_token = $json_obj['access_token'];

    $get_openid_url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$APPID.'&secret='.$APPSECRET.'&code='.$code.'&grant_type=authorization_code';
    $res = post($get_openid_url);
    $json_obj = json_decode($res,true);
    $openid = $json_obj['openid'];

    $get_user_base_info_url = "https://api.weixin.qq.com/cgi-bin/user/info?access_token=$access_token&openid=$openid&lang=zh_CN";
    $res = post($get_user_base_info_url);

    $param = base64_encode($res);
    $url = "http://218.***.***.10:8151/HiRunAdd.aspx?p=$param";

    header("Location:".$url);
/*
   $get_userinfo_url = "https://api.weixin.qq.com/sns/userinfo?access_token=".$access_token."&openid=".$openid."&lang=zh_CN";
   $res = post($get_userinfo_url);

    //解析json
    $user_obj = json_decode($res,true);
    $_SESSION['user'] = $user_obj;
    print_r($user_obj);
    echo "<br/>";
*/

function post($url){
   echo "url: $url <br/>";
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch,CURLOPT_HEADER,0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
    $res = curl_exec($ch);
    curl_close($ch);
    echo "resp: $res <br/><br/>";
    return $res;
}
?>

 

 等到用户 基本信息格式如下：

{
    "subscribe": 1,   //是否已订阅
    "openid": "oZA7CjhnBRG0SziGtMG216EK8L-g",  //用户openid
    "nickname": "碎石头",       //用户昵称
    "sex": 1,                          //用户性别
    "language": "zh_CN",       //用户所用语言
    "city": "所在城市",  
    "province": "所在省份", 
    "country": "中国", 
    "headimgurl": "http://wx.qlogo.cn/mmopen/qE9MKluetOnjPBkUB95h3vo4HsStkrKEQtYVgD6iad1yib75TW92OHQyZYgIialhMQ2tKe4iaciakAv92o0U1Y9cPug/0",   //用户头像地址
    "subscribe_time": 1434330625,   //用户订阅时间
    "remark": "",     //备注
    "groupid": 0       //用户所在用户组，如果有分组的话
}
