开发指引

1. 接口规则

为了在保证支付安全的前提下，带给商户简单、一致且易用的开发体验，我们推出了全新的微信支付APIv3接口。该版本API的具体规则请参考“APIv3接口规则”

2. 开发环境搭建

为了帮助开发者调用开放接口，我们提供了Java、PHP、GO语言版本的开发库，封装了签名生成、签名验证、敏感信息加/解密、媒体文件上传等基础功能

JAVA Golang PHP

2.1.1. 使用条件

• WechatPay merchant account

• Java 1.8 or later

• Maven or Gradle;

• 0.4.6 or later version of the Java httpClient SDK

2.1.2. 安装

Gradle：在你的 build.gradle 文件中加入如下的依赖

implementation 'com.github.wechatpay-apiv3:wechatpay-apache-httpclient:0.4.7'

Maven：在 pom.xml 文件中加入以下依赖

<dependency>
<groupId>com.github.wechatpay-apiv3</groupId>
<artifactId>wechatpay-apache-httpclient</artifactId>
<version>0.4.7</version>
</dependency>

2.1.3. 初始化

用WechatPayHttpClientBuilder初始化创建一个httpClient，httpClient将被用于发送请求调用微信支付接口。用CertificatesManager初始化一个verifier实例，用于验证签名。


    private CloseableHttpClient httpClient;
    private CertificatesManager certificatesManager;
    private Verifier verifier;

    @Before
    //initialize verifier and build httpClient
    public void setup() throws GeneralSecurityException, IOException, HttpCodeException, NotFoundException {

        PrivateKey merchantPrivateKey = PemUtil.loadPrivateKey(privateKey);
        certificatesManager = CertificatesManager.getInstance();
        certificatesManager.putMerchant(merchantId, new WechatPay2Credentials(merchantId,
                        new PrivateKeySigner(merchantSerialNumber, merchantPrivateKey)),
                apiV3Key.getBytes(StandardCharsets.UTF_8));
        verifier = certificatesManager.getVerifier(merchantId);
        WechatPayHttpClientBuilder builder = WechatPayHttpClientBuilder.create()
                .withMerchant(merchantId, merchantSerialNumber, merchantPrivateKey)
                .withValidator(new WechatPay2Validator(verifier));
        httpClient = builder.build();
    }

2.1.4. 通用功能

    @Test
    public void encryptedTest() throws IllegalBlockSizeException {
        String text = "helloWorld";
        String transformation = "RSA/ECB/PKCS1Padding";
        String encryptedText = RsaCryptoUtil.encrypt(text, verifier.getValidCertificate(), transformation);
        System.out.println(encryptedText);
    }


    @Test
    public void decryptedTest() throws BadPaddingException {
        String encryptedText = OBTgun4jiN13n3nmSg8v0MNDMy3mbs380yq4GrgO8vwCqXnvrWxwo3jUCNY2UY7MIOtv/SD8ke64MxcSB0hn5EzKv1LOLprI3NvvmNLS4C3SBulxpZG62RYp1+8FgwAI4M//icXvjtZWVH4KVDg==";
        String transformation = "RSA/ECB/PKCS1Padding";
        String decryptedText = RsaCryptoUtil.decrypt(encryptedText, PemUtil.loadPrivateKey(privateKey), transformation);
        assert("helloWorld".equals(decryptedText));
    }

2.2.1. 使用条件

• WechatPay merchant account

• GO SDK 0.2.13 or later version

2.2.2. 安装

1. 使用 Go Modules 管理你的项目

如果你的项目还不是使用 Go Modules 做依赖管理，在项目根目录下执行：

go mod init

2. 无需 clone 仓库中的代码，直接在项目目录中执行：

go get -u github.com/wechatpay-apiv3/wechatpay-go

来添加依赖，完成 go.mod 修改与 SDK 下载

2.2.3. 初始化

初始化Client并向Client中加载商户号，私钥，API V3 key，商户证书和序列号，用于之后发送接口请求。

require_once('vendor/autoload.php');

use WeChatPay\Builder;
use WeChatPay\Crypto\Rsa;
use WeChatPay\Util\PemUtil;

$merchantId = '190000****';
$merchantPrivateKeyFilePath = 'file:///path/to/merchant/apiclient_key.pem';
$merchantPrivateKeyInstance = Rsa::from($merchantPrivateKeyFilePath, Rsa::KEY_TYPE_PRIVATE);
$merchantCertificateSerial = '3775B6A45ACD588826D15E583A95F5DD********';
$platformCertificateFilePath = 'file:///path/to/wechatpay/cert.pem';
$platformPublicKeyInstance = Rsa::from($platformCertificateFilePath, Rsa::KEY_TYPE_PUBLIC);
$platformCertificateSerial = PemUtil::parseCertificateSerialNo($platformCertificateFilePath);

// init a API V3 instance
$instance = Builder::factory([
    'mchid'      => $merchantId,
    'serial'     => $merchantCertificateSerial,
    'privateKey' => $merchantPrivateKeyInstance,

	$encryptedMsg =  $encryptor('HelloWorld');


    $decryptor = static function(string $msg) use ($merchantPrivateKeyInstance): string {
        return Rsa::decrypt($msg, $merchantPrivateKeyInstance, OPENSSL_PKCS1_PADDING);
    };
	$decryptedMsg =  $decryptor('ciphertext');

3. 业务时序图

3.1. 业务时序图

机构提交子商户进件申请后，微信支付将对该子商户的资料进行系统审核，并返回进件是否成功或需要进一步人工审核的状态，所以机构需要关注接口返回结果：

进件成功进件失败进件需进一步人工审核


{
	"sub_mchid": "20000100",
	"verification_status": "Approved"
}


{
  "code": "INVALID_REQUEST",
  "message": "Parameter format verification error",
  "detail": {
    "field": "#/properties/payer",
    "value": "1346177081915535577",
    "issue": "Does not match the ALLOF schema",
    "location": "body"
  }
}


{
  "sub_mchid": "20000100",
  "verification_status": "Under Review",
  "description": "This merchant takes effect only after being approved. Please check the verification status on WeChat Pay Merchant Platform."
}

注意：此时该子商户没有支付权限，无法发起交易。需等待该子商户审核通过后，方可发起交易。机构可通过子商户查询接口，查询子商户的状态。

查询子商户状态

机构提交子商户进件申请后，可通过查询接口，查询子商户的状态：

OPERATING：正常；子商户已通过审核，入驻流程结束。其支付权限正常，可发起交易；

DEACTIVATED：已停用；该子商户在入驻审核通过后被机构自主停用，无支付权限，不能发起交易；

CLOSED：已关闭；该子商户在入驻审核通过后，被微信支付关闭支付权限，不能发起交易；

INCOMPLETE_APPLICATION：未完成入驻；子商户入驻申请未完成，无支付权限，不能发起交易。请于application_status字段查看入驻申请状态；

PENDING：待处理；该子商户在入驻审核通过后，其商户资料未通过日常复核，需要机构登录微信支付商户平台查看和处理。子商户权限正常，可发起交易。

子商户未完成入驻审核的处理

若查询到子商户状态为INCOMPLETE_APPLICATION，需进一步于application_status字段查看入驻申请状态：

UNDER_REVIEW：审核中；微信支付的审核人员正在审核该子商户的入驻申请，请耐心等待，可在一天后再次查询。如果申请完成后7个工作日后，状态仍为UNDER_REVIEW，可联系微信支付工作人员咨询；

REJECTED：已驳回；该子商户的入驻申请被微信支付驳回，需机构登录微信支付商户平台修改资料后重新提交（请于application_rejected_detail字段查看驳回原因）

3.2. API接入示例

文档展示了如何使用微信支付服务端 SDK 快速接入扫码支付产品，完成与微信支付对接的部分。

注意

• 文档中的代码示例是用来阐述 API 基本使用方法，代码中的示例参数需替换成商户自己账号及请求参数才能跑通。

• 以下接入步骤仅提供参考，请商户结合自身业务需求进行评估、修改。

3.2.1 进件子商户

步骤说明：机构提交子商户资料，微信支付系统会为每个子商户创建子商户号。

敏感信息字段：对于包含了敏感信息的参数，如联系方式等，我们增加了“字段加密”的安全机制，保护敏感信息只能被数据的接收方看到。

加密方法

• 获取微信支付平台证书和对应的平台证书序列号，获取微信支付平台证书。本接口请求http头的“Wechatpay-Serial”需要传平台证书序列号。

• 使用微信支付平台证书的公钥，对于需要加密的参数值进行RSA加密。Java语言的加密方法的填充方案使用 RSA/ECB/PKCS1Padding ;PHP填充方式为OPENSSL_PKCS1_PADDING。

• 加密后的密文，使用base64编码后，作为请求中相应参数的值。

3.2.3 修改子商户

步骤说明：用于机构子商户创建成功后，接口提供子商户信息修改

敏感信息字段：对于包含了敏感信息的参数，如联系方式等，我们增加了“字段加密”的安全机制，保护敏感信息只能被数据的接收方看到。

加密方法

• 获取微信支付平台证书和对应的平台证书序列号，获取微信支付平台证书。本接口请求http头的“Wechatpay-Serial”需要传平台证书序列号。

• 加密后的密文，使用base64编码后，作为请求中相应参数的值。

代码示例

JAVA Go PHP json

4. 通过子商户进件接口为子商户申请H5支付权限

对于H5支付的产品介绍，请阅读H5支付权限申请 / 产品介绍。

为方便机构在申请子商户时为子商户申请H5支付权限，我们在子商户进件/修改/查询API接口内融合了H5权限申请能力。

4.1. H5支付权限状态定义及状态转移

子商户进件/修改/查询API接口的回包中，使用 h5_authorization_state 表示子商户的H5支付权限状态；该状态会决定您应当对子商户进行何种操作：

● UNAUTHORIZED 未授权：子商户未在微信支付系统开通支付权限，请通过修改子商户接口填写H5申请资料为子商户申请H5支付权限；或者您也可以直接通过进件子商户接口填写H5申请资料，直接获得H5支付权限状态为UNDER_REVIEW的子商户；

● UNDER_REVIEW 审核中：您的H5支付权限申请单已受理，微信支付的审核人员将在3～5个工作日左右完成申请单审核；请通过查询子商户接口查询审核结果；

● REJECETED 已驳回：您的H5支付权限申请单被驳回，请通过查询子商户接口查询具体驳回原因后，通过修改子商户接口更新H5申请资料；

● APPROVED 已通过：您的H5支付权限申请已通过，H5支付权限已开通。如果您需要修改H5支付域名，请通过修改子商户接口更新域名（注意：域名会根据您的输入全量更新）；

● UNDER_PUNISHMENT 处罚中：子商户违反微信支付条例，处于被处罚阶段，请联系BD处理；

● APPLICATION_FAILED 申请失败：您的H5支付申请失败，请通过查询子商户接口查询失败原因后，通过修改子商户接口重新申请H5支付权限。
