流程：
微信用户从微信公众号进入查询页面（网页授权获取openid）,进行提交申请单。
后台管理员进行审核（支付，驳回），主要记录支付操作。
事先准备：
1、商户号
2、公众号（开通支付功能）
3、商户号绑定到公众号
4、证书（由商户号进行生成导出，用于api验证）
主要操作：主要两个动作（获取openid，付款）
一、 获取用户openid，并记录。（时间，申请金额什么的乱七八糟的参数略略略略）
可由公众号会话生成（未用）
网页授权生成（因为有页面用此方法）
由中转页获取code并请求获取用户openid。
jump.php
<?php
$url = "http:**************/jump.php";
baseAuth($url);
/**
* 获取用户的openid
* @param string $openid [description]
* @return [type] [description]
*/
function baseAuth($redirect_url)
{
//1.准备scope为snsapi_base网页授权页面
$baseurl = urlencode($redirect_url);
$snsapi_base_url = 'https://open.weixin.qq.com/connect/oauth2/authorize?appid=w***ad&redirect_uri=' . $baseurl . '&response_type=code&scope=snsapi_base&state=YQJ#wechat_redirect';
//2.静默授权,获取code
//页面跳转至redirect_uri/?code=CODE&state=STATE
$code = $_GET['code'];
if (!isset($code)) {
header('Location:' . $snsapi_base_url);
}
//3.通过code换取网页授权access_token和openid
$curl = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid=w*****&secret=0*****18&code=' . $code . '&grant_type=authorization_code';
$content = curl($curl);
$result = json_decode($content, true);
header("Location:http*******alance.php?open_id={$result['openid']}");//最终页面
}
//设置网络请求配置
function curl($curl, $https = true, $method = 'GET', $data = null)
{
// 创建一个新cURL资源
$ch = curl_init();
// 设置URL和相应的选项
curl_setopt($ch, CURLOPT_URL, $curl); //要访问的网站
curl_setopt($ch, CURLOPT_HEADER, false); //启用时会将头文件的信息作为数据流输出。
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //将curl_exec()获取的信息以字符串返回，而不是直接输出。
if ($https) {
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); //FALSE 禁止 cURL 验证对等证书（peer's certificate）。
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, true); //验证主机
}
if ($method == 'POST') {
curl_setopt($ch, CURLOPT_POST, true); //发送 POST 请求
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //全部数据使用HTTP协议中的 "POST" 操作来发送。
}
// 抓取URL并把它传递给浏览器
$content = curl_exec($ch);
if ($content === false) {
return "网络请求出错: " . curl_error($ch);
exit();
}
//关闭cURL资源，并且释放系统资源
curl_close($ch);
return $content;
}二、 付款（用到之前准备项）
1、请求参数（简化过了，针对不同进行需求修改）

....

$arr = array(

'openid' => $open_id,//接收人openid
'amount' => $money * 100,//单位分
'desc' => '微信提现',//描述
