找到 网页授权获取用户基本信息 然后修改-->填写你的域名.如下:

index.php如下:

//scope=snsapi_base 实例 $appid='你的AppId'; $redirect_uri = urlencode ( 'http://你的域名/getUserInfo.php' ); $url ="https://open.weixin.qq.com/connect/oauth2/authorize?appid=$appid&redirect_uri=$redirect_uri&response_type=code&scope=snsapi_base&state=1#wechat_redirect"; header("Location:".$url);

getUserInfo.php如下:

$appid = "你的AppId"; $secret = "你的AppSecret"; $code = $_GET["code"]; //第一步:取全局access_token $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$secret"; $token = getJson($url); //第二步:取得openid $oauth2Url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$appid&secret=$secret&code=$code&grant_type=authorization_code"; $oauth2 = getJson($oauth2Url);   //第三步:根据全局access_token和openid查询用户信息 $access_token = $token["access_token"]; $openid = $oauth2['openid']; $get_user_info_url = "https://api.weixin.qq.com/cgi-bin/user/info?access_token=$access_token&openid=$openid&lang=zh_CN"; $userinfo = getJson($get_user_info_url); //打印用户信息 print_r($userinfo); function getJson($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); }

index.php如下:

//scope=snsapi_userinfo实例 $appid='你的AppId'; $redirect_uri = urlencode ( 'http://你的域名/getUserInfo.php' ); $url ="https://open.weixin.qq.com/connect/oauth2/authorize?appid=$appid&redirect_uri=$redirect_uri&response_type=code&scope=snsapi_userinfo&state=1#wechat_redirect"; header("Location:".$url);

getUserInfo.php如下:

$appid = "你的AppId"; $secret = "你的AppSecret"; $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"; $oauth2 = getJson($oauth2Url); //第二步:根据全局access_token和openid查询用户信息 $access_token = $oauth2["access_token"]; $openid = $oauth2['openid']; $get_user_info_url = "https://api.weixin.qq.com/cgi-bin/user/info?access_token=$access_token&openid=$openid&lang=zh_CN"; $userinfo = getJson($get_user_info_url); //打印用户信息 print_r($userinfo); function getJson($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); }

3)然后用微信扫一扫,刚刚你生成的二维码.
