easywechat laravel 公众号 微信支付
首先、申请微信商户平台，申请微信支付，公众号关联微信商户平台
公众号可以通过jsapi来实现公众号微信支付
一、业务页面
@extends('m.order')
@section('content')
<style type="text/css">
input, textarea {
border: 0;
-webkit-appearance: none;
}
</style>
<section class="container">
<div class="pay_main">
<div class="ay_ma1"><span>付款金额</span><em><i>￥</i>{{$total_price}}</em></div><!--ay_ma1-->
<div class="ay_ma2">订单编号：{{$order_no}}</div><!--ay_ma2-->
<div class="ay_ma2">付款方式</div><!--ay_ma2-->
<div class="ay_ma3"><span>微信支付</span><label></label></div>
{{--<div class="ay_ma3"><span>微信支付</span><label><input name="" type="radio" value="" checked></label></div>--}}
<div class="ay_ma4">
<ul>
<button type="button" onclick="wxPay()" id="pay_button">确认付款</button>
</ul>
</div><!--ay_ma4-->
</div><!--pay_main-->
<input type="hidden" id="order_no" value="{{$order_no}}">
<input type="hidden" id="code" value="">
</section>
@endsection
@section('js')
<script type="text/javascript" src="/static/new/m/js/jweixin-1.4.0.js"></script>
<script type="text/javascript" src="/static/new/m/js/pay.js"></script>
@endsection
二、前端pay.js逻辑
$(function () {
var layer;
layui.use(['layer'], function () {
layer = layui.layer;
});
$('#pay_button').hide();
wxConfig();
wx.ready(function(){
$('#pay_button').show();
});
});
function wxConfig() {
var order_no = $('#order_no').val();
$.ajax({
type:"GET",
url:"/wechat/pay",
data:{order_no:order_no},
success:function (config) {
// 微信配置
wx.config({
debug: false,
appId: config.appId,
timestamp: config.timeStamp,
nonceStr: config.nonceStr,
signature: config.signature,
jsApiList: ['chooseWXPay']
});
}
});
}
function wxPayAuth(orderPayNo) {
window.location.href = '/mp/oauth?targetUrl=/pay/request?orderPayNo=' + orderPayNo;
}
var jsApiConfig;
function wxPay() {
var order_no = $('#order_no').val();
$.ajax({
type:"GET",
url:"/wechat/pay",
data:{order_no:order_no},
success:function (config) {
jsApiConfig = config;//请求微信成功返回的支付参数
callpay();
}
})
}
//调用微信JS api 支付
function jsApiCall()
{
WeixinJSBridge.invoke(
'getBrandWCPayRequest',jsApiConfig,
function(res){
//WeixinJSBridge.log(res.err_msg);
//alert(res.err_code+res.err_desc+res.err_msg);
if(res.err_msg == "get_brand_wcpay_request:ok" ) {
layer.msg('支付成功', {time: 1000, end: function () {
location.href = '/inquiry/index';
}});
}else{
layer.msg('支付失败,请重试');
}
});
}
function callpay()
{
if (typeof WeixinJSBridge == "undefined"){
if( document.addEventListener ){
document.addEventListener('WeixinJSBridgeReady', jsApiCall, false);
}else if (document.attachEvent){
document.attachEvent('WeixinJSBridgeReady', jsApiCall);
document.attachEvent('onWeixinJSBridgeReady', jsApiCall);
}
}else{
jsApiCall();
}
}
三、服务端处理页面
