确认登录后

页面会访问这个url

http://starks.ngrok.wdevelop.cn/act.php?code=0615P8s314BY1P1CVSq31r98s315P8sI&state=STATE

通过code换取网页授权access_token

代码实现

require_once('Curl.php');$code = $_GET['code'];$appid = "****************************";$secret = "****************************";$url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid={$appid}&secret={$secret}&code={$code}&grant_type=authorization_code";echo "
";$data = Curl::CurlGet($url);$data = (array)json_decode($data);var_dump($data);

返回数据

string(339) "{"access_token":"4_rBAOjGbsn_mnhXIP-5vu6dFk98tNG76faFqgvUSjwivpY8eSnvRlfXBSKilHA3vFNSXHA8kB9k0CWfHSYDid3g","expires_in":7200,"refresh_token":"4_PdBbZZl13PuA1w2sKIDAz4WhZcbozeYNcJfFDHBxfpsofo8b_1UfgS6H_cVqe1wQwfEEhmqTnQ_tzFScjTd3xg","openid":"oPs5ouLW3qg7P6CLj-jS7M1XVtSw","scope":"snsapi_userinfo","unionid":"o28P7ww-ZMphcik-5ZSbkCr_QTQw"}"

拉取用户信息(需scope为 snsapi_userinfo)

代码实现

$access_token = $data['access_token'];$openid = $data['openid'];$userurl = "https://api.weixin.qq.com/sns/userinfo?access_token={$access_token}&openid={$openid}&lang=zh_CN";$userdata = Curl::CurlGet($userurl);$userdata = (array)json_decode($userdata);var_dump($userdata);

返回数据

string(343) "{"openid":"oPs5ouLW3qg7P6CLj-jS7M1XVtSw","nickname":"stark.wang","sex":1,"language":"zh_CN","city":"","province":"北京","country":"中国","headimgurl":"http:\/\/wx.qlogo.cn\/mmopen\/vi_32\/Q0j4TwGTfTJFHGcYsxe4TjLibiaDEicB8l2vv869kNLvfQ4P8WbO6adBmdTAH1s4h0JaH1oEZhU5icBApC6pXclF4Q\/0","privilege":[],"unionid":"o28P7ww-ZMphcik-5ZSbkCr_QTQw"}"

转换成数组格式

array(10) {  ["openid"]=>  string(28) "****************************"  ["nickname"]=>  string(10) "stark.wang"  ["sex"]=>  int(1)  ["language"]=>  string(5) "zh_CN"  ["city"]=>  string(0) ""  ["province"]=>  string(6) "北京"  ["country"]=>  string(6) "中国"  ["headimgurl"]=>  string(124) "http://wx.qlogo.cn/mmopen/vi_32/Q0j4TwGTfTJFHGcYsxe4TjLibiaDEicB8l2vv869kNLvfQ4P8WbO6adBmdTAH1s4h0JaH1oEZhU5icBApC6pXclF4Q/0"  ["privilege"]=>  array(0) {  }  ["unionid"]=>  string(28) "o28P7ww-ZMphcik-5ZSbkCr_QTQw"}
