微信小程序支付签名问题

[xiearthur]

我用的环境

PHP 版本：7.1
overtrue/wechat 版本：4.0
是否使用了框架？框架名称：laravel5.4

问题及现象

小程序提示错误
return_code: "FAIL", return_msg: "签名错误
小程序代码
wxpay(){
wx.request({
url: getApp().api.get_v3_pay,
header: {
'content-type': 'application/json'
},
data: {

  }, success: res => {
    console.log(res)
    wx.requestPayment({
      timeStamp: '',
      nonceStr: '',
      package: '',
      signType: '',
      paySign: '',
    })

** laravel代码**
public function pay(){
$payment = \EasyWeChat::payment(); // 微信支付
$result = $payment->order->unify([
'body' => '测试支付',
'out_trade_no' => '263565',
'trade_type' => 'JSAPI', // 必须为JSAPI
'openid' => 'oRHbw0Fsrlvpr_AEnfI', // 有所修改
'total_fee' => 1, // 总价
]);
// 如果成功生成统一下单的订单，那么进行二次签名
if ($result['return_code'] === 'SUCCESS') {
// 二次签名的参数必须与下面相同
$params = [
'appId' => 'wx001aeca67195585b',//有所修改
'timeStamp' => time(),
'nonceStr' => $result['nonce_str'],
'package' => 'prepay_id=' . $result['prepay_id'],
'signType' => 'MD5',
];

        // config('wechat.payment.default.key')为商户的key
        $params['paySign'] = generate_sign($params, config('wechat.payment.default.key'));

        return  $params;
    } else {

     return $result;
    }
