微信登陆代码
网页访问 https://open.weixin.qq.com/connect/oauth2/authorize?appid=xxx&redirect_uri=http://dopan.net/ceshiweixin.php&response_type=code&scope=snsapi_userinfo&state=123&connect_redirect=1#wechat_redirect 保存以下内容至文件，回调至这个网页 <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> </head> <body> <?php $code = $_GET['code']; $state = $_GET['state']; //换成自己的接口信息 $appid = 'xxx'; $appsecret = 'xxx'; if (empty($code)) $this->error('授权失败'); $token_url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$appid.'&secret='.$appsecret.'&code='.$code.'&grant_type=authorization_code'; $token = json_decode(file_get_contents($token_url)); if (isset($token->errcode)) { echo '<h1>错误：</h1>'.$token->errcode; echo '<br/><h2>错误信息：</h2>'.$token->errmsg; exit; } $access_token_url = 'https://api.weixin.qq.com/sns/oauth2/refresh_token?appid='.$appid.'&grant_type=refresh_token&refresh_token='.$token->refresh_token; //转成对象 $access_token = json_decode(file_get_contents($access_token_url)); if (isset($access_token->errcode)) { echo '<h1>错误：</h1>'.$access_token->errcode; echo '<br/><h2>错误信息：</h2>'.$access_token->errmsg; exit; } $user_info_url = 'https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token->access_token.'&openid='.$access_token->openid.'&lang=zh_CN'; //转成对象 $user_info = json_decode(file_get_contents($user_info_url)); if (isset($user_info->errcode)) { echo '<h1>错误：</h1>'.$user_info->errcode; echo '<br/><h2>错误信息：</h2>'.$user_info->errmsg; exit; } //打印用户信息 echo '<pre>'; print_r($user_info); echo '</pre>'; ?> </body> </html>
如果微信开发的时候碰到了redirect_uri 参数错误的问题，尝试一下方法
