本案例使用的支付接口是 PayJs 微信支付商户,没有商户号可以自己申请:https://payjs.cn/ref/DNXBJD
演示
1 分钱体验
流程
1、写出进群界面
2、对接 PayJs 的 JSAPI 支付接口
3、支付成功后跳转进群二维码
代码
jiaqun-login.php
这个代码主要是授权登录,获取用户的 openid

}
// 发送
$result = post($url);
// 返回接口的数据

?>
jiaqun-getopenid.php
这个主要是把获取到的 openid 传到支付订单页面
<?php
header("Content-type:text/html;charset=utf8");
$openid = $_GET["openid"];
// 浏览器跳转
echo "<script>location.href=\" 你的域名 / 你的支付目录 /jiaqun-pay.php?openid=$openid\";</script>";
?>
<title> 请稍候 </title>
jiaqun-pay.php
这个主要是构建订单发起请求参数,创建支付订单
<?php
// 引入配置文件
require_once("config.php");
// 获得 OPENID
$openid = $_GET["openid"];
// 定义金额
$total_fee = 1;
$length = strlen($total_fee);
if ($length == 1) {$money = "0.0".$total_fee;}else if ($length == 2) {$money = "0.".substr($total_fee, 0,1).substr($total_fee, 1,1);
}else if ($length == 3) {$money = substr($total_fee, 0,1).".".substr($total_fee, 1,1).substr($total_fee, 2,3);
}else if ($length == 4) {$money = substr($total_fee, 0,1).substr($total_fee, 1,1).".".substr($total_fee, 2,3).substr($total_fee, 4,4);
}else if ($length == 5) {$money = substr($total_fee, 0,1).substr($total_fee, 1,1).substr($total_fee, 2,1).".".substr($total_fee, 3,2);
}
// 构造订单参数
$data = [
'mchid' => $mchid,
'body' => '付费进群',
'total_fee' => $total_fee,
'openid' => $openid,
'out_trade_no' => 'likeyunkeji.' . time(),];
// 添加数据签名
$data['sign'] = sign($data, $key);
// 发送请求
$url = 'https://payjs.cn/api/jsapi?' . http_build_query($data);
function post($data, $url) {$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
$rst = curl_exec($ch);
curl_close($ch);
return $rst;
}
// 发送
$result = post($data, $url);
// 返回接口的数据
$results = json_decode($result);
// 返回字符串
$appId = $results->jsapi->appId;
$timeStamp = $results->jsapi->timeStamp;
$nonceStr = $results->jsapi->nonceStr;
$package = $results->jsapi->package;
$signType = $results->jsapi->signType;
$paySign = $results->jsapi->paySign;
// 获取签名

我这里是没有做订单查询的,真正的项目是要做异步订单查询才可以。
以上代码直接可以用了,修改商户号就行了。
商户号需要你开通 PayJs 才可以获取到。开通链接:https://payjs.cn/ref/DNXBJD
