详细接口或参数说明,以支付宝官方文档为准, 支付宝API网址(https://opendocs.alipay.com/apis)
一.手机网站支付(H5版)
1.导入支付宝提供的jar,此为Maven版
<dependency> <groupId>com.alipay.sdk</groupId> <artifactId>alipay-sdk-java</artifactId> <version>4.9.124.ALL</version> </dependency>
2.关键支付代码
//网关地址,APPID,商户应用私钥,数据格式,编码格式,支付宝公钥,签名算法类型 AlipayClient alipayClient = new DefaultAlipayClient(aliPayGateway,appID,rsa_private_key,format,charset,alipayPublicKey,signType);
//不同支付类型需使用不同的请求对象 AlipayTradeWapPayRequest request = new AlipayTradeWapPayRequest(); //请求参数集合对象,除了公共参数之外,所有参数都可通过此对象传递(不同支付类型需使用不同的请求参数对象) AlipayTradeWapPayModel model = new AlipayTradeWapPayModel(); //订单描述 model.setBody("订单描述"); //订单标题 model.setSubject("显示效果见于下图的标题"); //商户订单号 model.setOutTradeNo(orderNo); //订单的过期时长(取值为5m - 15d,即五分钟到十五天) model.setTimeoutExpress("30m"); //订单总金额 model.setTotalAmount(String.valueOf(cashNum)); //产品码 QUICK_WAP_WAY:无线快捷支付产品 model.setProductCode("QUICK_MSECURITY_PAY"); //用户付款中途退出返回商户网站的地址 model.setQuitUrl("https://wwww.baidu.com"); request.setBizModel(model); //支付成功后的跳转地址 request.setReturnUrl("支付成功之后的跳转地址"); //支付成功后的回调地址(此地址必须为公网地址,用于支付宝收到用户付款之后,通知我们的服务端,我们可以在此接口中更改订单状态为已付款或后续操作) request.setNotifyUrl(aliPayNotifyUrl); String orderStr = ""; AlipayTradeWapPayResponse responseH5 = null; try { responseH5 = alipayClient.pageExecute(request); } catch (AlipayApiException e) { return ReturnUtils.returnVal(CommonConstants.appCode.UNKNOWNERROR.get(),null); } orderStr = responseH5.getBody(); Map<String, String> result = new HashMap<String, String>(); result.put("orderStr", orderStr); result.put("outTradeNo", orderNo); return ReturnUtils.returnVal(CommonConstants.appCode.SUCCESS.get(), result);
3.响应返回参数(为支付的form表单,前端解析此表单即可)
{ "code": 49000, "msg": "操作成功", "result": { "orderStr": "<form name=\"punchout_form\" method=\"post\" action=\"https://openapi.alipay.com/gateway.do?charset=utf-8&method=alipay.trade.wap.pay&sign=

二.APP支付
1.跟手机网站支付一样,需要如下参数
2.支付宝APP支付关键代码
//支付宝网关地址:https://openapi.alipay.com/gateway.do
//支付宝申请的APPID
//商户应用私钥(与支付宝数据交互时,保证数据安全,防止数据被篡改)
//支付宝公钥(与支付宝数据交互时,保证数据安全,防止数据被篡改)
//签名算法类型(RSA2或者RSA,支付宝推荐使用RSA2)
//编码格式(utf-8,gb2312,gbk)
//网关地址,APPID,商户应用私钥,数据格式,编码格式,支付宝公钥,签名算法类型
AlipayClient alipayClient = new DefaultAlipayClient(aliPayGateway,appID,rsa_private_key,format,charset,alipayPublicKey,signType);
//不同支付方式需使用不同的请求对象 AlipayTradeAppPayRequest request = new AlipayTradeAppPayRequest();
//请求参数集合对象,除了公共参数之外,所有参数都可通过此对象传递(不同支付类型需使用不同的请求参数对象) AlipayTradeAppPayModel model = new AlipayTradeAppPayModel(); model.setBody("订单描述"); model.setSubject("订单标题");
//订单编号,此订单号不可重复 model.setOutTradeNo(getTradeNo()); //设置过期时间 model.setTimeoutExpress("30m"); model.setProductCode("QUICK_WAP_WAY"); model.setTotalAmount(String.valueOf(cashNum)); request.setBizModel(model); //设置回调地址 request.setNotifyUrl("支付成功后,支付宝来回调的地址,此地址必须为公网地址,否则出现调不通"); String orderStr = ""; AlipayTradeAppPayResponse response1 = null; try { response1 = alipayClient.sdkExecute(request); } catch (AlipayApiException e) { return ReturnUtils.returnVal(CommonConstants.appCode.UNKNOWNERROR.get(), null); } orderStr = response1.getBody(); Map<String, String> result = new HashMap<String, String>(); result.put("orderStr", orderStr); result.put("outTradeNo", getTradeNo()); return ReturnUtils.returnVal(CommonConstants.appCode.SUCCESS.get(), result);
3.APP支付响应参数
//此响应信息为自己包装过的数据,result数据返回至APP即可
{ "code": 49000, "msg": "操作成功", "result": { "orderStr": "alipay_sdk=alipay-sdk-java-dynamicVersionNo&app_id=2021001181677544&biz_content=%7B%22body%22%3A%2223212%22%2C%22out_trade_no%22%3A%22d89006ef-630b-41e5-a78e-3fee47e72506%22%2C%22product
