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();
    }

        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,
    'certs'      => [
        $platformCertificateSerial => $platformPublicKeyInstance,
    ],
]);

2.3.4. 通用功能

    $encryptor = static function(string $msg) use ($platformPublicKeyInstance): string {
        return Rsa::encrypt($msg, $platformPublicKeyInstance, OPENSSL_PKCS1_PADDING);
    };
	$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

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 身份信息校验

步骤说明：该接口允许商户请求微信支付对用户支付用户的实名信息与入参中的身份信息进行一致性校验，商户可以根据校验结果使用正确的信息进行报关。

敏感信息字段：certificate_id 和 certificate_name 为用户敏感信息，为避免被中间人截获，保护用户隐私，需要按照微信支付APIv3 加密后传输。

加密方法

• 下载微信支付平台证书，获取证书序列号与证书公钥。

• 在 HTTP header 中添加微信支付平台证书序列号，Wechatpay-Serial ：${微信支付平台证书序列号}。

• 使用微信支付平台证书公钥对敏感字段进行RSA加密，填充方案选择 RSAES-PKCS1-v1_5。

• 对密文进行 base64 编码后即可得到最终内容。
