和QQ⽹页授权登录
⼀：授权
//⽤户授权
public function is_weixin(){
$url = "open.weixin.qq/connect/oauth2/authorize?appid=xxxxxxxxxxxxxxx&redirect_uri=/index.php/privilege/getWeixinUser&response_type=code&scope=snsapi_userinfo&state=1#wechat_redirect" redirect($url);
}
上⾯的$url 中有5个get参数，前⾯2个get参数的值由我们指定，即appid 和 redirect_uri
appid="APP_ID"
redirect_uri="回调地址"
以上例⼦中 is_weixin ⽅法执⾏后浏览器会访问 redirect_uri所填写的地址，也就是会执⾏privilege中的g
etWeixinUser⽅法
public function getWeixinUser(){
$appid = "xxxxxxxxxxxxxxxxxxxxxxx";
$secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$code = $_GET["code"];
$get_token_url = 'api.weixin.qq/sns/oauth2/access_token?appid='.$appid.'&secret='.$secret.'&code='.$code.'&grant_type=authorization_code';
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$get_token_url);
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
$res = curl_exec($ch);
curl_close($ch);
$json_obj = json_decode($res,true);
//根据openid和access_token查询⽤户信息
$access_token = $json_obj['access_token'];
$openid = $json_obj['openid'];
$get_user_info_url = 'api.weixin.qq/sns/userinfo?access_token='.$access_token.'&openid='.$openid.'&lang=zh_CN';
$ch = curl_init();杜鹃花养殖
curl_setopt($ch,CURLOPT_URL,$get_user_info_url);
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
$res = curl_exec($ch);
curl_close($ch);
//解析json
$user_obj = json_decode($res,true);
// array(
// [openid] => o3ushwi5OiaBfCNA2F187BKPdnfU
/
/ [nickname] => xxx
// [sex] => 1
// [language] => zh_CN
// [city] => 深圳
// [province] => ⼴东
// [country] => 中国
// [headimgurl] => wx.qlogo/mmopen/qibdIUkiaxRnic3D9icdBOonZxI3HibH1sP1xKchqhlDOnQibVuxhfNxHVvRJCrfz9jOkR5uZxsWiaToMIQQ0spkRNfG325j8NaGO67/0
// );
}
getWeixinUser⽅法中最终得到的$user_obj就是⼀个包含了⽤户基本信息的数组。
⼆：QQ授权
第⼀步，跳转到QQ授权页⾯，获取(Authorization) Code值
/*QQ登陆*/
public function qqlogin(){
$appid = 'xxxxxxxxxxx';
$appkey = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$scope = "get_user_info";
//成功授权后的回调地址，需要进⾏urlencode
$my_url = "www.nightlostk/index.php/privilege/callback";
set_sess('state',md5(uniqid(rand(), TRUE)));
$login_url = "graph.qq/oauth2.0/authorize?response_type=code&client_id=".$appid."&redirect_uri=" .urlencode($my_url)."&state=".get_sess('state')."&scope=".$scope;
redirect($login_url);
}
代码运⾏后会跳转到类似如下页⾯:
⽤户点击QQ头像即表⽰授权并登录。页⾯将会跳转到上⾯代码中的回调地址
//成功授权后的回调地址，需要进⾏urlencode
$my_url = "www.nightlostk/index.php/privilege/callback";
实际上回调地址会附带⼀些上get参数。实际的地址为: www.nightlostk/index.php/privilege/callback?code=xxxxxxxxxxxx&state=xxxxxxxxxxxxxx
可以理解为第⼀步就是为了获取到返回的get参数 code的值
第⼆步, 通过Authorization Code获取Access Token->openid->⽤户基本信息
在第⼀步中，页⾯最后跳转到
www.nightlostk/index.php/privilege/callback?code=xxxxxxxxxxxx&state=xxxxxxxxxxxxxx
在PHP中会执⾏ privilege中的 callback⽅法
/*QQ登陆回调地址*/
public function callback(){
$appid = '101261269';
$appkey = 'adcaacfadd912ecc5991aa6936aafe0d';
笼组词语$my_url = "m.etripbon/index.php/privilege/callback";
//Step2：通过Authorization Code获取Access Token
if($_REQUEST['state'] == get_sess('state')) {
$code = $_REQUEST["code"];
//拼接URL
$token_url = "graph.qq/oauth2.0/token?grant_type=authorization_code&"."client_id=".$appid."&redirect_uri=".urlencode($my_url)."&client_secret=".$appkey."&code=".$code;健康美容小常识
$response = $this->https_request($token_url);
//Step3：使⽤Access Token来获取⽤户的OpenID
$params = array();
parse_str($response, $params);
$graph_url = "graph.qq/oauth2.0/me?access_token=".$params['access_token'];
$access_token = $params["access_token"];
$str = $this->https_request($graph_url);
$user = json_decode($str);$openid = $user->openid;
$url = "graph.qq/user/get_user_info?access_token=".$access_token."&oauth_consumer_key=".$appid."&openid=".$openid;
$output = $this->https_request($url);
$jsoninfo = json_decode($output, true);
}else{
echo("The state does not match. You may be a victim of CSRF.");
}
}
public function https_request($url,$data = null){
if(function_exists('curl_init')){
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);
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;
}else{
return false;

在callback⽅法中，通过第⼀步获取的code值来组装好url
graph.qq/oauth2.0/token?grant_type=authorization_code&"."client_id=".$appid."&redirect_uri=".urlencode($my_url)."&client_secret=".$appkey."&code=".$code
请求这个url 获取到 Access Token
Access Token 有了以后组装出如下url
$graph_url = "graph.qq/oauth2.0/me?access_token=".$params['access_token']
请求这个url 获取到⽤户的 openid
网上购物去哪里openid 有了以后组装出如下url
$url = "graph.qq/user/get_user_info?access_token=".$access_token."&oauth_consumer_key=".$appid."&openid=".$openid；请求这个url 获取到⽤户的基本信息，到此为⽌，⽤户的QQ基本信息就获取到了。后续则是根据⾃⼰项⽬的业务需求来处理这些信息即可。返回的QQ⽤户基本信息如下图所⽰
