braintree支付开发

braintree介绍

流程介绍

braintree流程图

前端从服务端请求一个客户端令牌，并初始化客户端SDK。
服务端SDK生成客户端令牌并将其发送回客户端
客户提交付款信息，客户端SDK将该信息传递给Braintree，并返回付款方式随机数
前端付款方式随机数发送给服务端
服务端收到付款方式随机数后，使用SDK向Braintree发起交易请求。

环境配置

注册Braintree帐号

前往braintree开发者文档注册沙盒帐号

登录后点击齿轮⚙==>API==>Keys==>APIKeys==>PrivateKey==>View 备用

直接支付

公司的流程和代码不符合，看看流程就好

参考官方Set Up Your Client

该例子创建了信用卡支付、paypal支付

后端代码

//简单的gatway配置，来自braintree帐号
public class GatewayFactory {public static BraintreeGateway getlisiGateway() {BraintreeGateway gateway = new BraintreeGateway(Environment.SANDBOX,"f6tw2cm2c24yfbs7", "ds8szsps6fc9tjky", "bf4a3e7971a8e4be2dada2f7ca19573a");return gateway;}
}

@RestController
@RequestMapping("/braintree")
public class BraintreeController {private static BraintreeGateway gateway = GatewayFactory.getlisiGateway();@PostMapping("/getToken")public String getToken(){//官方写new ClientTokenRequest().customerId("customerId")可以不要。ClientTokenRequest clientTokenRequest = new ClientTokenRequest();String clientToken = gateway.clientToken().generate(clientTokenRequest);return clientToken;}//从前端获取的交易信息不只有nonce，还有金额，设备等，orderId也可以传@PostMapping("/pay")public Msg pay(String nonce) {TransactionRequest request = new TransactionRequest().amount(new BigDecimal("10.00")).paymentMethodNonce(nonce).deviceData("h5").options().submitForSettlement(true).done();Result<Transaction> result = gateway.transaction().sale(request);if(result.isSuccess()){return Msg.ok(result.getTarget().getStatus().toString());}else{return Msg.fail(result.getMessage());}}
}

坑点

官方写new ClientTokenRequest().customerId(“customerId”)可以不要。
Transaction状态会自动转，算是官方的审核时间，自动的。
- 信用卡 submit_for_settlted 后续过30分钟自动转为 settlted
- paypal settlting 后续过30分钟自动转为 settlted
