注意本例用的是tp3.2框架

数据表

1.access_token表

2.wechat_user表

配置

//微信公众号配置    'WX_TOKEN'                 =>'weixin',//Token(令牌)    'WX_APPID'                 =>'w**************6',//AppID(应用ID)    'WX_APPSECRET'             =>'6*************************0',//AppSecret(应用密钥)

公用函数

/** * 模拟请求 */function _curl($URL = '', $post_data = array(),$timeout=0){    $cu = curl_init();    if($post_data){        curl_setopt($cu, CURLOPT_POST, 1);//post提交方式        curl_setopt($cu, CURLOPT_POSTFIELDS, $post_data);//post提交的数据    }    curl_setopt($cu, CURLOPT_SSL_VERIFYPEER, FALSE);    curl_setopt($cu, CURLOPT_URL, $URL);    curl_setopt($cu, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上    curl_setopt($cu, CURLOPT_CONNECTTIMEOUT, $timeout);//在发起连接前等待的时间，如果设置为0，则无限等待。    $response = curl_exec($cu);    curl_close($cu);    return $response;}
