The payment and refund process of the WeChat mini program

When I was working on the WeChat mini program recently, it involved the payment and refund process of the mini program, so I also roughly summarized this aspect. I’ve read everything over and over, and I’ll summarize it in this blog.

First of all, let me explain that the main logic of WeChat applet payment is concentrated on the backend. The frontend only needs to carry the data required for payment to request the backend interface and then handle the corresponding success or failure based on the returned results. I use PHP on the backend. Of course, in this blog I am not going to post a bunch of code to explain the specific implementation of payment, but will mainly focus on the entire payment process and some details. Therefore, friends who use other back-end languages ????can take a look if necessary. Many times, development needs and corresponding problem solutions really need to go beyond the language syntax level and be considered from the perspective of systems and processes. Okay, no more nonsense. Into the title.

1. Payment

Payment is mainly divided into several steps:

The front end carries the data required for payment (commodity id, purchase quantity, etc.) to initiate a payment request

After receiving the payment request, the backend processes the payment data, and then carries the processed data requestWeChat serverPayment unified order interface

The backend receives the return data from the previous request to the WeChat server, processes it again, and then returns to the frontend so that the frontend can start payment.

Front-end performs payment action

After the front-end payment is completed, the WeChat server will send a payment notification to the back-end (that is, WeChat wants to tell you that the customer has paid), and the back-end will act according to this notification Make sure the payment is completed, and then take the corresponding actions after the payment is completed, such as modifying the order status, adding transaction logs, etc.

從這幾個(gè)步驟可以看出，后端主要的作用就是將支付需要的數(shù)據(jù)傳給微信服務(wù)器，再根據(jù)微信服務(wù)器的響應(yīng)確定支付是否完成。

這個(gè)流程還是蠻容易理解的。形象的說(shuō)，前端就是個(gè)顧客，后端就是店家，微信服務(wù)器的統(tǒng)一下單接口就像收銀員。顧客跟店家說(shuō)，
我是誰(shuí)誰(shuí)誰(shuí)，現(xiàn)在我要付多少多少錢(qián)給你買(mǎi)什么什么。店家就跟收銀員說(shuō)，那個(gè)誰(shuí)誰(shuí)誰(shuí)要付多少錢(qián)，你準(zhǔn)備收錢(qián)吧。收銀員收到錢(qián)
后，就去告訴店家，我已經(jīng)收到錢(qián)了，你給他東西吧。

The following is a detailed explanation of the specific implementation of each step.

1. Front-end request for payment

前端請(qǐng)求支付，就是簡(jiǎn)單的攜帶支付需要的數(shù)據(jù)，例如用戶(hù)標(biāo)識(shí)，支付金額，支付訂單?ID?等等跟?**你的業(yè)務(wù)邏輯有關(guān)**?或者跟
?**下一步請(qǐng)求微信服務(wù)器支付統(tǒng)一下單接口需要的數(shù)據(jù)有關(guān)**?的相關(guān)數(shù)據(jù)，使用微信小程序的?wx.request(?)?去請(qǐng)求后端的支
?付接口。

2. Front-end request for payment

后端接收到前端發(fā)送的支付請(qǐng)求后，可以進(jìn)行一下相關(guān)驗(yàn)證，例如判斷一下用戶(hù)有沒(méi)有問(wèn)題，支付金額對(duì)不對(duì)等等。
在驗(yàn)證沒(méi)什么問(wèn)題，可以向微信服務(wù)器申請(qǐng)支付之后，后端需要使用?微信規(guī)定的數(shù)據(jù)格式?去請(qǐng)求微信的支付統(tǒng)一下單接口。

Request data specified by WeChat:
This requires more code accomplish. Because the amount of data required is large, it also needs to be encrypted and sent in XML format.
First of all, the following data are parameters that must be provided to the WeChat server when using mini program payment.

Mini program appid. There is probably no one who writes small programs who doesn’t know this. . .

User ID openid. That is the user's mini program ID. I explained how to obtain it in my last blog.

Merchant number mch_id. After successfully applying for WeChat payment merchant certification, the email sent to you by WeChat will contain

merchant order number out_trade_no. The order number

generated by the merchant for this payment is the total amount total_fee. The total amount of the order, a very important point is that the unit is cents, so pay special attention to it.

WeChat server callback notification interface address notify_url. After WeChat confirms that the money has arrived, it will send multiple messages to this address to tell you that the customer has paid.

You need to return a message to WeChat to indicate that you have received the notification. . This address cannot have a port number, and must be able to directly accept POST method requests.

Transaction type trade_type. The WeChat applet payment value is unified as JSAPI

Product Information Body. Similar to the format of "Tencent-Game"

Terminal IP address spbill_create_ip. Terminal address IP, which is the IP address requesting payment.

Random string nonce_str. A string randomly generated by the backend is required to ensure data security. WeChat requires no longer than 32 bits.

signature sign. Use all the above parameters to process the encryption and generate the signature accordingly. (The specific processing method can be seen in the code below, which can be reused directly.)

After processing all the above data, organize the data in XML format and send it to WeChat Payment Unification using the POST method Order interface https://api.mch.weixin.qq.com/pay/unifiedorder.

3. The backend accepts the data returned by the WeChat server

After the WeChat server receives the payment data, if there is no problem with the data, it will return the corresponding data for payment. The most important thing is The data field named prepay_id needs to return this data to the front end so that the front end can continue to pay.

Therefore, after the back-end receives the return data from the WeChat server, it needs to perform corresponding processing, and finally return the following data to the front-end:

1. appid No Need to say more

2. timeStamp current timestamp

3. nonceStr random string

4. package That’s it Mentioned prepay_id, but remember the format is like "prepay_id= prepay_id_item". Otherwise an error will result.

5. signType Encryption method, generally should be MD5

6. paySign Process and encrypt the above data accordingly.

到這里，后端的支付接口已經(jīng)完成了接收前端支付請(qǐng)求，并返回了前端支付所需數(shù)據(jù)的功能。

4. 前端發(fā)起支付

前端在接收到返回?cái)?shù)據(jù)后，使用 wx.requestPayment() 來(lái)請(qǐng)求發(fā)起支付。此 API 需要的對(duì)象參數(shù)各項(xiàng)值就是我們上一步返回的各個(gè)數(shù)據(jù)。

5.后端接受微信服務(wù)器回調(diào)

前端完成支付后，微信服務(wù)器確認(rèn)支付已經(jīng)完成。就會(huì)向第一步中設(shè)置的回調(diào)地址發(fā)送通知。后端的接收回調(diào)接口在接收到通知后，就可以判斷支付是否完成，從而決定后續(xù)動(dòng)作。

需要注意的是，在接收到微信服務(wù)器的回調(diào)通知后，根據(jù)通知的result_code字段判斷支付是否成功。在接受到成功的通知后，后端需要返回success數(shù)據(jù)向微信服務(wù)器告知已得到回調(diào)通知。否則微信服務(wù)器會(huì)不停的向后端發(fā)送消息。另外微信的通知是以XML格式發(fā)送的，在接受處理時(shí)需要注意。

微信的大概支付流程就是這樣。以下是PHP語(yǔ)法的微信支付類(lèi)，可以比照上面的步驟介紹，加深理解。在需要支付時(shí)，直接傳入?yún)?shù)實(shí)例化此類(lèi)再調(diào)用類(lèi)的 pay 方法即可。

以上就是微信支付的相關(guān)流程。在理清思路后，流程還是比較清晰和簡(jiǎn)單的。重點(diǎn)在于需要注意一些細(xì)節(jié)問(wèn)題，例如數(shù)據(jù)格式，加密方法等。

下面說(shuō)一下微信小程序退款的具體實(shí)現(xiàn)

二.退款

小程序退款的流程和付款相似，但有一些細(xì)節(jié)上的不同。

首先退款的步驟通常如下:

1. 用戶(hù)前端點(diǎn)擊退款按鈕后，后端接收到用戶(hù)的退款請(qǐng)求通過(guò)商城后臺(tái)呈現(xiàn)給商戶(hù)，商戶(hù)確定允許退款后，后端再發(fā)起向微信退款接口的請(qǐng)求來(lái)請(qǐng)求退款。
2. 后端向微信退款接口發(fā)送請(qǐng)求后，得到響應(yīng)信息，確定退款是否完成，根據(jù)退款是否完成再去進(jìn)行改變訂單狀態(tài)等業(yè)務(wù)邏輯。

退款的步驟相對(duì)微信支付來(lái)說(shuō)比較簡(jiǎn)單。

值得注意的有以下兩點(diǎn)：
1.向微信退款接口請(qǐng)求退款后，根據(jù)得到的響應(yīng)是可以直接確定退款是否完成的。不再需要設(shè)置專(zhuān)門(mén)的回調(diào)接口等待微信通知。當(dāng)然如果需要也是可以在微信商戶(hù)平臺(tái)設(shè)置回調(diào)接口接受從而接受微信回調(diào)的，但并不是必須的。
2.退款請(qǐng)求需要在請(qǐng)求服務(wù)器安裝微信提供的安全證書(shū)，也就是說(shuō),發(fā)起退款請(qǐng)求相比較支付請(qǐng)求在請(qǐng)求時(shí)請(qǐng)求方法不能復(fù)用,因?yàn)槲⑿磐丝钚枰獢y帶證書(shū)的請(qǐng)求,此證書(shū)可在申請(qǐng)微信商戶(hù)號(hào)成功后從微信商戶(hù)平臺(tái)自行下載，Linux下的PHP開(kāi)發(fā)環(huán)境的證書(shū)只需要放在網(wǎng)站根目錄的cert文件夾中即可。其他開(kāi)發(fā)環(huán)境可能需要導(dǎo)入操作。

下面講解一下退款的具體步驟

一. 用戶(hù)發(fā)起退款請(qǐng)求

用戶(hù)在前端發(fā)起退款請(qǐng)求,后端接收到退款請(qǐng)求,將相應(yīng)訂單標(biāo)記為申請(qǐng)退款,展示在后臺(tái).商戶(hù)查看后,如果同意退款再進(jìn)行相應(yīng)操作.
此后才進(jìn)入真正的退款流程.

二. 商戶(hù)發(fā)起退款請(qǐng)求

    商戶(hù)同意退款后,后端即向微信提供的退款 API 發(fā)起請(qǐng)求.
    同請(qǐng)求微信支付API一樣.退款請(qǐng)求也需要將需要的參數(shù)進(jìn)行簽名后以XML發(fā)送到微信的退款A(yù)PI 
    [https://api.mch.weixin.qq.com/pay/refund](https://api.mch.weixin.qq.com/pay/refund)

退款請(qǐng)求需要的參數(shù)如下(多個(gè)參數(shù)在支付API請(qǐng)求時(shí)也有使用):

1. 小程序 appid。
2. 商戶(hù)號(hào) mch_id 。申請(qǐng)開(kāi)通微信支付商戶(hù)認(rèn)證成功后微信發(fā)給你的郵件里有
3. 商戶(hù)訂單號(hào) out_trade_no 。退款訂單在支付時(shí)生成的訂單號(hào)
4. 退款訂單號(hào) out_refund_no 。由后端生成的退款單號(hào)，需要保證唯一，因?yàn)槎鄠€(gè)同樣的退款單號(hào)只會(huì)退款一次。
5. 總金額 total_fee 。訂單總金額，單位為分。
6. 退款金額 refund_fee 需要退款的金額,單位同樣為分
7. 操作員 op_user_id .與商戶(hù)號(hào)相同即可
8. 隨機(jī)字符串 nonce_str 。同支付請(qǐng)求
9. 簽名 sign 。使用上面的所有參數(shù)進(jìn)行相應(yīng)處理加密生成簽名。（具體處理方式與支付相同，可直接復(fù)用。）

三. 退款完成

在發(fā)起退款請(qǐng)求后，就可以直接根據(jù)請(qǐng)求的響應(yīng)XML中的	result_code字段來(lái)判斷退款是否成功，
從而對(duì)訂單狀態(tài)進(jìn)行處理和后續(xù)操作。不需要像支付那樣等待另一個(gè)接口的通知來(lái)確定請(qǐng)求狀態(tài)。當(dāng)然如上文所說(shuō)，
如果需要微信服務(wù)器發(fā)送通知到后端的話(huà)，可以到微信商戶(hù)平臺(tái)進(jìn)行設(shè)置。

退款因?yàn)榱鞒膛c支付大同小異，因此退款的PHP類(lèi)我選擇了直接繼承支付類(lèi)，
代碼如下，注意區(qū)分退款請(qǐng)求方法postXmlSSLCurl和支付請(qǐng)求方法postXmlCurl的區(qū)別，這也就是上文提到的退款需要的雙向證書(shū)的使用。

   
     class WinXinRefund extends WeiXinPay{
        protected \$SSLCERT_PATH = 'cert/apiclient_cert.pem';//證書(shū)路徑
        protected \$SSLKEY_PATH =  'cert/apiclient_key.pem';//證書(shū)路徑
        protected \$opUserId = '1234567899';//商戶(hù)號(hào)
        
    function __construct($openid,$outTradeNo,$totalFee,$outRefundNo,$refundFee){
