商家券開發(fā)指引

1. 接口規(guī)則

為了在保證支付安全的前提下，帶給商戶簡單、一致且易用的開發(fā)體驗，我們推出了全新的微信支付APIv3接口。該版本API的具體規(guī)則請參考“APIv3接口規(guī)則”

2. 開發(fā)準備

2.1. 搭建和配置開發(fā)環(huán)境

為了幫助開發(fā)者調(diào)用開放接口，我們提供了JAVA、PHP、GO三種語言版本的開發(fā)庫，封裝了簽名生成、簽名驗證、敏感信息加/解密、媒體文件上傳等基礎(chǔ)功能（更多語言版本的開發(fā)庫將在近期陸續(xù)提供）

測試步驟：

1、根據(jù)自身開發(fā)語言，選擇對應(yīng)的開發(fā)庫并構(gòu)建項目，具體配置請參考下面鏈接的詳細說明：

? wechatpay-java（推薦）wechatpay-apache-httpclient，適用于Java開發(fā)者。

? wechatpay-php（推薦）、wechatpay-guzzle-middleware，適用于PHP開發(fā)者

注：當前開發(fā)指引接口PHP示例代碼采用wechatpay-guzzle-middleware版本

? wechatpay-go，適用于Go開發(fā)者

更多資源可前往微信支付開發(fā)者社區(qū)搜索查看

2、創(chuàng)建加載商戶私鑰、加載平臺證書、初始化httpClient的通用方法

JAVA
PHP


@Before
public void setup() throws IOException {
    // 加載商戶私鑰（privateKey：私鑰字符串）
    PrivateKey merchantPrivateKey = PemUtil
            .loadPrivateKey(new ByteArrayInputStream(privateKey.getBytes("utf-8")));
 
    // 加載平臺證書（mchId：商戶號,mchSerialNo：商戶證書序列號,apiV3Key：V3密鑰）
    AutoUpdateCertificatesVerifier verifier = new AutoUpdateCertificatesVerifier(
            new WechatPay2Credentials(mchId, new PrivateKeySigner(mchSerialNo, merchantPrivateKey)),apiV3Key.getBytes("utf-8"));
 
    // 初始化httpClient
    httpClient = WechatPayHttpClientBuilder.create()
            .withMerchant(mchId, mchSerialNo, merchantPrivateKey)
            .withValidator(new WechatPay2Validator(verifier)).build();
}
 
@After
public void after() throws IOException {
    httpClient.close();
}


use GuzzleHttp\Exception\RequestException;
use WechatPay\GuzzleMiddleware\WechatPayMiddleware;
use WechatPay\GuzzleMiddleware\Util\PemUtil;
use GuzzleHttp\HandlerStack;
 
// 商戶相關(guān)配置，
$merchantId = '1000100'; // 商戶號
$merchantSerialNumber = 'XXXXXXXXXX'; // 商戶API證書序列號
$merchantPrivateKey = PemUtil::loadPrivateKey('./path/to/mch/private/key.pem'); // 商戶私鑰文件路徑
 
// 微信支付平臺配置
$wechatpayCertificate = PemUtil::loadCertificate('./path/to/wechatpay/cert.pem'); // 微信支付平臺證書文件路徑
 
// 構(gòu)造一個WechatPayMiddleware
$wechatpayMiddleware = WechatPayMiddleware::builder()
    ->withMerchant($merchantId, $merchantSerialNumber, $merchantPrivateKey) // 傳入商戶相關(guān)配置
    ->withWechatPay([ $wechatpayCertificate ]) // 可傳入多個微信支付平臺證書，參數(shù)類型為array
    ->build();
 
// 將WechatPayMiddleware添加到Guzzle的HandlerStack中
$stack = GuzzleHttp\HandlerStack::create();
$stack->push($wechatpayMiddleware, 'wechatpay');
 
// 創(chuàng)建Guzzle HTTP Client時，將HandlerStack傳入，接下來，正常使用Guzzle發(fā)起API請求，WechatPayMiddleware會自動地處理簽名和驗簽
$client = new GuzzleHttp\Client(['handler' => $stack]);


/*
    Package core 微信支付api v3 go http-client 基礎(chǔ)庫，你可以使用它來創(chuàng)建一個client，并向微信支付發(fā)送http請求
    只需要你在初始化客戶端的時候，傳遞credential以及validator
    credential用來生成http header中的authorization信息
    validator則用來校驗回包是否被篡改
    如果http請求返回的err為nil，一般response.Body 都不為空，你可以嘗試對其進行序列化
    請注意及時關(guān)閉response.Body
    注意：使用微信支付apiv3 go庫需要引入相關(guān)的包，該示例代碼必須引入的包名有以下信息

    "context"
    "crypto/x509"
    "fmt"
    "io/ioutil"
    "log"
    "github.com/wechatpay-apiv3/wechatpay-go/core"
    "github.com/wechatpay-apiv3/wechatpay-go/core/option"
    "github.com/wechatpay-apiv3/wechatpay-go/utils"

    */
func SetUp() (opt []option.ClientOption, err error) {
    //商戶號
    mchID := ""
    //商戶證書序列號
    mchCertSerialNumber := ""
    //商戶私鑰文件路徑
    privateKeyPath := ""
    //平臺證書文件路徑
    wechatCertificatePath := ""

    // 加載商戶私鑰
    privateKey, err := utils.LoadPrivateKeyWithPath(privateKeyPath)
    if err != nil {
        log.Printf("load private err:%s", err.Error())
        return nil, err
    }
    // 加載微信支付平臺證書
    wechatPayCertificate, err := utils.LoadCertificateWithPath(wechatCertificatePath)
    if err != nil {
        log.Printf("load certificate err:%s",err)
        return nil, err
    }
    //設(shè)置header頭中authorization信息
    opts := []option.ClientOption{
        option.WithMerchant(mchID, mchCertSerialNumber, privateKey), // 設(shè)置商戶相關(guān)配置
        option.WithWechatPay([]*x509.Certificate{wechatPayCertificate}), // 設(shè)置微信支付平臺證書，用于校驗回包信息用
    }
    return opts, nil
}

3、基于接口的示例代碼，替換請求參數(shù)后可發(fā)起測試

說明：

? 上面的開發(fā)庫為微信支付官方開發(fā)庫，其它沒有審核或者控制下的第三方工具和庫，微信支付不保證它們的安全性和可靠性

通過包管理工具引入SDK后，可根據(jù)下面每個接口的示例代碼替換相關(guān)參數(shù)后進行快速測試

? 開發(fā)者如果想詳細了解簽名生成、簽名驗證、敏感信息加/解密、媒體文件上傳等常用方法的具體代碼實現(xiàn)，可閱讀下面的詳細說明：

1.簽名生成

2.簽名驗證

3.敏感信息加解密

4.merchantPrivateKey（私鑰）

5.wechatpayCertificates（平臺證書）

6.APIV3Key（V3 key）

? 如想更詳細的了解我們的接口規(guī)則，可查看我們的接口規(guī)則指引文檔

2.2. 業(yè)務(wù)開發(fā)配置

2.2.1. 開通營銷事件推送能力

? 開通營銷事件推送能力說明：

a. 用于設(shè)置接收商家券相關(guān)事件通知的URL，可接收商家券相關(guān)的事件通知、包括發(fā)放通知等。需要設(shè)置接收通知的URL，并在服務(wù)商平臺開通營銷事件推送的能力，即可接收到相關(guān)通知。

b. 營銷事件推送：點擊開通產(chǎn)品權(quán)限。由商家券批次創(chuàng)建方登錄Pay平臺，操作開通

3. 快速接入

3.1. 業(yè)務(wù)流程圖

業(yè)務(wù)流程時序圖：

重點步驟說明：

步驟1 商戶發(fā)起創(chuàng)建商家券請求，可通過《創(chuàng)建商家券》接口創(chuàng)建商家券，微信支付生成商家券批次后并返回商家券批次號給到商戶。
請求參數(shù)商戶logo（merchant_url）的內(nèi)容要求使用圖片上傳（營銷專用）接口上傳后獲取

步驟4.2 商戶獲取到商家券批次號，需要調(diào)用《小程序發(fā)券插件》來發(fā)放商戶券，并獲取微信支付返回商家券發(fā)放結(jié)果。

步驟7.2 商戶發(fā)券成功后，商戶可通過《查詢商家券詳情》、《根據(jù)過濾條件查詢用戶券》、《查詢用戶券詳情》等商家券管理接口進行券管理，商戶需核銷用戶券時，可通過調(diào)用《核銷用戶券》來核銷用戶微信卡包中具體某一張商家券。

3.2. API接入（含示例代碼）

文檔展示了如何使用微信支付服務(wù)端 SDK 快速接入商家券產(chǎn)品，完成與微信支付對接的部分。

注意：

文檔中的代碼示例是用來闡述 API 基本使用方法，代碼中的示例參數(shù)需替換成商戶自己賬號及請求參數(shù)才能跑通。
以下接入步驟僅提供參考，請商戶結(jié)合自身業(yè)務(wù)需求進行評估、修改。

3.2.1. 【服務(wù)端】創(chuàng)建商家券

步驟說明：通過此接口可為有需求的商戶創(chuàng)建商家券。當前支持創(chuàng)建的商家券類型包含滿減券、換購券和折扣券三種。

示例代碼：

重要入?yún)⒄f明：

? belong_merchant：批次歸屬商戶號，批次歸屬于哪個商戶。服務(wù)商模式填寫為子商戶號，間連模式填寫為子商戶號

? out_request_no：商戶請求單號，商戶創(chuàng)建批次憑據(jù)號（格式：商戶id+日期+流水號），商戶側(cè)需保持唯一性。

? max_coupons：批次最大發(fā)放個數(shù)，批次最大可發(fā)放個數(shù)限制。特殊規(guī)則：取值范圍 1 ≤ value ≤ 1000000000

? notify_appid：事件通知appid，用于回調(diào)通知時，計算返回操作用戶的openid（諸如領(lǐng)券用戶），支持小程序or公眾號的APPID；如該字段不填寫，則回調(diào)通知中涉及到用戶身份信息的openid與unionid都將為空。

3.2.17.【服務(wù)端】領(lǐng)券事件回調(diào)通知

步驟說明：領(lǐng)券完成后，微信會把相關(guān)領(lǐng)券結(jié)果和用戶信息發(fā)送給商戶，商戶需要接收處理，并按照文檔規(guī)范返回應(yīng)答。出于安全的考慮，我們對支付結(jié)果數(shù)據(jù)進行了加密，商戶需要先對通知數(shù)據(jù)進行解密，才能得到支付結(jié)果數(shù)據(jù)。

注意：

領(lǐng)券事件通知是以POST 方法訪問商戶設(shè)置的通知url，通知的數(shù)據(jù)以JSON 格式通過請求主體（BODY）傳輸。通知的數(shù)據(jù)包括了加密的支付結(jié)果詳情
加密不能保證通知請求來自微信。微信會對發(fā)送給商戶的通知進行簽名，并將簽名值放在通知的HTTP頭Wechatpay-Signature。商戶應(yīng)當驗證簽名，以確認請求來自微信，而不是其他的第三方。簽名驗證的算法請參考《微信支付API v3簽名驗證》。
支付通知http應(yīng)答碼為200或204才會當作正常接收，當回調(diào)處理異常時，應(yīng)答的HTTP狀態(tài)碼應(yīng)為500，或者4xx
商戶成功接收到回調(diào)通知后應(yīng)返回成功的http應(yīng)答碼為200或204
同樣的通知可能會多次發(fā)送給商戶系統(tǒng)。商戶系統(tǒng)必須能夠正確處理重復(fù)的通知。推薦的做法是，當商戶系統(tǒng)收到通知進行處理時，先檢查對應(yīng)業(yè)務(wù)數(shù)據(jù)的狀態(tài)，并判斷該通知是否已經(jīng)處理。如果未處理，則再進行處理；如果已處理，則直接返回結(jié)果成功。在對業(yè)務(wù)數(shù)據(jù)進行狀態(tài)檢查和處理之前，要采用數(shù)據(jù)鎖進行并發(fā)控制，以避免函數(shù)重入造成的數(shù)據(jù)混亂
對后臺通知交互時，如果微信收到應(yīng)答不是成功或超時，微信認為通知失敗，微信會通過一定的策略定期重新發(fā)起通知，盡可能提高通知的成功率，但微信不保證通知最終能成功。（通知頻率為60s/次 - 總計11次）

Q：調(diào)用創(chuàng)建商家券接口返回“非法敏感圖片”

A：請求參數(shù)商戶logo（merchant_url）的內(nèi)容要求使用圖片上傳（營銷專用）接口上傳后獲取，請檢查確認。

Q：創(chuàng)建商家券接口，goods_name字段展示在哪里？

A：展示在商家券詳情里面的優(yōu)惠說明中

Q：調(diào)用修改商家券基本信息API返回：無法將輸入源“/body/stock_id”映射到目標字段“批次號”中，此字段并非多重字段但被輸入源“/uri_template/stock_id”映射過了

A：請注意參數(shù)stock_id傳到請求url里面，body里面就不用傳該參數(shù)

Q：商家券領(lǐng)券回調(diào)，正常設(shè)置地址，為什么接收不到回調(diào)信息？

A：請按以下幾點檢查

1. 請檢查是否有正確設(shè)置apiv3。設(shè)置步驟如下：【微信服務(wù)商平臺—>賬戶設(shè)置—>API安全—>設(shè)置apiv3】

2. 請檢查回調(diào)url是否能正常公網(wǎng)訪問

3. 如果是http地址，建議更換支持https

4. 是否開啟了防火墻，如果開戶了防火墻，請?zhí)砑游⑿胖Ц稜I銷回調(diào)IP：
