準備
本案例使用的支付接口是PayJs微信支付商戶，沒有商戶號可以自己申請:https://payjs.cn/ref/DNXBJD
演示
1分錢體驗
流程
1、寫出進羣界面
2、對接PayJs的JSAPI支付接口
3、支付成功後跳轉進羣二維碼
代碼
jiaqun-login.php
這個代碼主要是授權登錄，獲取用戶的openid

<?php
header("Content-type:text/html;charset=utf8");
//發送請求
$url = 'https://payjs.cn/api/openid?callback_url=你的域名/你的支付目錄/jiaqun-getopenid.php';
function post($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_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
$rst = curl_exec($ch);
curl_close($ch);
return $rst;
}
//發送
$result = post($url);
//返回接口的數據
echo "<p style=\"display:none;\">".$result."</p>";
?>jiaqun-getopenid.php
這個主要是把獲取到的openid傳到支付訂單頁面
<?php
header("Content-type:text/html;charset=utf8");
$openid = $_GET["openid"];
//瀏覽器跳轉
echo "<script>location.href=\"你的域名/你的支付目錄/jiaqun-pay.php?openid=$openid\";</script>";
?>
<title>請稍候</title>jiaqun-pay.php
這個主要是構建訂單發起請求參數，創建支付訂單
<?php
//引入配置文件
require_once("config.php");
//獲得OPENID
$openid = $_GET["openid"];
//定義金額
$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);
}
// 構造訂單參數
$data = [
'mchid' => $mchid,
'body' => '付費進羣',
'total_fee' => $total_fee,
'openid' => $openid,
'out_trade_no' => 'likeyunkeji.' . time(),
];
// 添加數據簽名
$data['sign'] = sign($data, $key);
//發送請求
$url = 'https://payjs.cn/api/jsapi?' . http_build_query($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;
}
//發送
$result = post($data, $url);
//返回接口的數據
$results = json_decode($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 = $results->jsapi->paySign;
// 獲取簽名
function sign($data, $key)
{
array_filter($data);
ksort($data);
return strtoupper(md5(urldecode(http_build_query($data) . '&key=' . $key)));

}我這裏是沒有做訂單查詢的，真正的項目是要做異步訂單查詢纔可以。
以上代碼直接可以用了，修改商戶號就行了。
商戶號需要你開通PayJs纔可以獲取到。開通鏈接：https://payjs.cn/ref/DNXBJD
