準備

本案例使用的支付接口是PayJs微信支付商戶，沒有商戶號能夠本身申請:https://payjs.cn/ref/DNXBJDjavascript

演示

1分錢體驗

流程

一、寫出進羣界面
二、對接PayJs的JSAPI支付接口
三、支付成功後跳轉進羣二維碼php

代碼

jiaqun-login.php
這個代碼主要是受權登陸，獲取用戶的openidcss

<body>

</body>
</html>
<?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html

<?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，建立支付訂單java

<?php
//引入配置文件
require_once("config.php");

//得到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)));
}
?>

我這裏是沒有作訂單查詢的，真正的項目是要作異步訂單查詢才能夠。api

以上代碼直接能夠用了，修改商戶號就好了。瀏覽器

商戶號須要你開通PayJs才能夠獲取到。開通連接：https://payjs.cn/ref/DNXBJD微信
