node+vue实现微信支付(沙箱)完整版,亲测可用

2022-11-04 23:05:15

网上很多资料文档都是残次不全的,没几个真正有用的，我这记录下可用的实现方式

微信的沙箱的区别就是在正常的所有api前面加一个sandboxnew。

1，事前准备

这里的商户必须要跟商户绑定过才行,不然会报错,

1.1获取沙箱秘钥

function getKey(){
    //首先拿到前端传过来的参数
    let orderCode = 'xy16143316973304295';
    let money     = 1.01;

    //首先生成签名sign
    let mch_id = mchid;
    let nonce_str = wxpay.createNonceStr();
    let timestamp = wxpay.createTimeStamp();
    let body = '微信支付';
    let out_trade_no = orderCode;
    let total_fee = wxpay.getmoney(money);
    let spbill_create_ip = '49.235.115.11';//终端ip
    let notify_url = wxurl;
    let trade_type = 'NATIVE';
    let sign = wxpay.paysignjsapi(appid,body,mch_id,nonce_str,notify_url,out_trade_no,spbill_create_ip,total_fee,trade_type,mchkey);mchkey// 秘钥要是正式的秘钥才可以获取
    //组装xml数据
    var formData  = "<xml>";
    formData  += "<appid>"+appid+"</appid>";  //appid
    formData  += "<body><![CDATA["+"微信支付"+"]]></body>";
    formData  += "<mch_id>"+mch_id+"</mch_id>";  //商户号
    formData  += "<nonce_str>"+nonce_str+"</nonce_str>"; //随机字符串，不长于32位。
    formData  += "<notify_url>"+notify_url+"</notify_url>";
    formData  += "<out_trade_no>"+out_trade_no+"</out_trade_no>";
    formData  += "<spbill_create_ip>"+spbill_create_ip+"</spbill_create_ip>";
    formData  += "<total_fee>"+total_fee+"</total_fee>";
    formData  += "<trade_type>"+trade_type+"</trade_type>";
    formData  += "<sign>"+sign+"</sign>";
    formData  += "</xml>";
    let promise = new Promise(function(resolve, reject) {
        let urls = "https://api.mch.weixin.qq.com/sandboxnew/pay/getsignkey"
        request({url:urls,method:'POST',body: formData},function(err,response,body){
            if(!err && response.statusCode == 200){
                xmlreader.read(body.toString("utf-8"), function (errors, response) {
                    var sandbox_signkey = response.xml.sandbox_signkey.text()
                    resolve(sandbox_signkey)
                });
            }
        })
    });
    return promise
}

2,封装方法

function wxpPys(sorder,smoney) {
    //首先拿到前端传过来的参数
    let orderCode = sorder;
    let money = smoney;

    //首先生成签名sign
    let mch_id = wechatConfig.mchid;
    let appid = wechatConfig.appid;
    let mchkey = wechatConfig.mchkey;
    let nonce_str = wxpay.createNonceStr();
    let timestamp = wxpay.createTimeStamp();
    let body = '微信支付';
    let out_trade_no = orderCode;
    let total_fee = wxpay.getmoney(money);
    let spbill_create_ip = '49.235.115.11';//终端ip
    let notify_url = wechatConfig.wxurl;
    let trade_type = 'NATIVE';
    let sign = wxpay.paysignjsapi(appid,body,mch_id,nonce_str,notify_url,out_trade_no,spbill_create_ip,total_fee,trade_type,mchkey);
    //组装xml数据
    let formData  = "<xml>";
    formData  += "<appid>"+appid+"</appid>";  //appid
    formData  += "<body><![CDATA["+"微信支付"+"]]></body>";
    formData  += "<mch_id>"+mch_id+"</mch_id>";  //商户号
    formData  += "<nonce_str>"+nonce_str+"</nonce_str>"; //随机字符串，不长于32位。
    formData  += "<notify_url>"+notify_url+"</notify_url>";
    formData  += "<out_trade_no>"+out_trade_no+"</out_trade_no>";
    formData  += "<spbill_create_ip>"+spbill_create_ip+"</spbill_create_ip>";
    formData  += "<total_fee>"+total_fee+"</total_fee>";
    formData  += "<trade_type>"+trade_type+"</trade_type>";
    formData  += "<sign>"+sign+"</sign>";
    formData  += "</xml>";
    var url = 'https://api.mch.weixin.qq.com/sandboxnew/pay/unifiedorder';
    let promise = new Promise(function(resolve, reject) {
        request({url:url,method:'POST',body: formData},function(err,response,body){
            if(!err && response.statusCode == 200){
                console.log(body);
                xmlreader.read(body.toString("utf-8"), function (errors, response) {
                    console.log(response.xml)
                    var code_url = response.xml.code_url.text();
                    resolve(code_url)
                });
            }
        })
    });
    return promise
}

3,接口定义

/**
 * 添加购物车支付微信 */
router.post('/api/member/payOrder', (req, res) => {

    let orderId=req.body.orderId
    let reuct =  new wxpPys(orderId,1.01)
    reuct.then(response=>{
        res.send(
            {
                "success": true,
                "message": "success",
                "code": 200,
                "timestamp": (new Date()).getTime(),
                "result": response
            }
        )
    })

})

查询订单:

/**
 * 添加购物车提交订单微信支付后查询订单状态是否成功 */
router.post('/api/member/queryOrderWechat', (req, res) => {
    let orderId=req.body.orderId
    let reuct =  new queryOrder(orderId,1.01)
    reuct.then(response=>{

        console.log(response)

        res.send(
            {
                "success": true,
                "message": "success",
                "code": 200,
                "timestamp": (new Date()).getTime(),
                "result": response
            }
        )
    })
})

这里要强调沙箱版是不需要扫码的,等于弹出微信自动扫码支付了,直接看结果就行!

正式的时候就把所有链接中的sandboxnew去掉就行
