平台H5对接支付宝支付接口(含分布式源码)

简介
本文详细介绍通过支付宝开放平台开发助手生成密钥对、支付宝证书申请 CSR 文件步骤。
说明：生成密钥、CSR 文件后，开发者需根据生成并配置密钥指引，完成控制台及接口调用配置。
前提条件
• 已完成开发者入驻以及实名认证。详情可查看支付宝个人账号注册及实名认证、支付宝企业账号注册及实名认证。
• 已下载并安装下载密钥生成工具（支付宝开放平台开发助手）。
获取工具
• WINDOWS（Windows 版本工具请不要安装在含有空格的目录路径下，否则会导致公私钥乱码的问题）。
• MAC_OSX
原理介绍
支付宝开放平台开发助手提供了一键生成密钥功能，便于开发者生成一对 RSA 密钥（应用公钥、应用私钥）以及公钥证书申请 CSR 文件（在线申请应用公钥证书需要）。
注意事项
• 应用公钥（public key）需提供给支付宝账号管理者上传到支付宝开放平台。
• 应用私钥（private key）由开发者自己保存，需填写到代码中供签名时使用。
• 生成的私钥需妥善保管，避免遗失，不要泄露。
• 密钥和应用（APPID）一一对应，即开发者需要为名下的每个应用分别设置密钥，且不同应用的密钥不能混用。
公钥方式
本步骤指引以 MAC_OSX 界面为例。

根据开发语言选择密钥格式和密钥长度。
说明：
• 新建应用请务必使用 RSA2 密钥长度即 2048 位。详情可查看开放平台证书升级指南。
• 目前已使用 RSA 密钥长度即 1024 位密钥长度的应用仍然可以正常调用接口。

点击生成密钥，工具会自动生成商家应用公钥（public_key）和应用私钥（private_key）。随后点击打开密钥文件路径。

在弹出的 RSA密钥文件夹下即可找到生成的公私钥文件。
根据生成并配置密钥指引完成密钥配置。

公钥证书方式
本步骤指引以 MAC_OSX 界面为例。
2. 在开发助手工具的生成密钥工具，密钥长度选择 RSA2，密钥格式选择 PKCS8（Java适用），点击获取CSR文件后的点击获取，生成应用公钥证书 CSR 申请文件。

在弹出的获取 CSR 对话框中根据提示填写相关信息，支付宝会根据提供的信息创建证书的标识名称，用来识别证书，点击生成 CSR 文件。
说明：
• 组织/公司：名称一定要和开发者中心门户账号信息的公司名称保持一致，否则会导致后续步骤中上传 CSR 证书文件校验失败。
• 沙箱环境下配置 CSR 公钥证书时，若沙箱账号为：
• 2020 年 07 月 24 日前获取的沙箱账号，组织/公司需固定填写沙箱环境。
• 2020 年 07 月 24 日后获取的沙箱账号，组织/公司需填写沙箱商家账号，例如：沙箱商家账号为 xxx@sandbox.com，组织/公司就需要配置成 xxx@sandbox.com。
• 域名建议填写商家/服务商公司域名地址。

在生成 CSR 文件后，点击打开文件位置，在对应的文件夹里可以看到三个文件：应用公钥 key 串、应用私钥 key 串，以及 .csr 格式的应用公钥证书申请文件。

根据生成并配置密钥指引完成密钥配置

请求示例

AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do","app_id","your private_key","json","GBK","alipay_public_key","RSA2");
AlipayTradeCloseRequest request = new AlipayTradeCloseRequest();
JSONObject bizContent = new JSONObject();
bizContent.put("trade_no", "2013112611001004680073956707");
request.setBizContent(bizContent.toString());
AlipayTradeCloseResponse response = alipayClient.execute(request);
if(response.isSuccess()){ 
   
System.out.println("调用成功");
} else { 
   
System.out.println("调用失败");
}
