微信登录网页授权与APP授权
微信JSAPI支付
微信APP支付
微信APP和JSAPI退款
支付宝手机网站支付
支付宝APP支付
支付宝退款
以上我都放到个人公众号,搜一搜:JAVA大贼船,文末有公众号二维码!觉得个人以后开发会用到的可以关注一下哦!少走点弯路…
支付宝手机网站支付没有微信支付那么琐碎(这里真的是想吐槽一下wxpay,配置太多了,文档阅读性也不友好!!),支付宝官方文档已经写得挺详细了,所以本文不对参数做详细的解释
https://opendocs.alipay.com/open/203/107084
https://opendocs.alipay.com/apis/api_1/alipay.trade.wap.pay
开发者使用支付宝账号登录开放平台(需实名认证的支付宝账号),根据实际需求创建应用(如“支付应用”)。
备注:创建应用时的应用状态为“开发中”,无法在线上正式调用接口。

到这里支付宝支付就成功了,是不是相当微信支付简单多了_,接下来支付宝支付成功就会回调页面和服务端啦
官方文档:https://opendocs.alipay.com/open/203/105286
@ApiOperation("支付宝回调")
@PostMapping("callback")
public String callback(HttpServletRequest request) throws Exception {
Object object = new Object();
Map<String, String> params = convertRequestParamsToMap(request);
log.info("支付宝回调:已回调,参数为====" + params);
try {
checkCallbackAlipay(params);
/*处理一些业务*/
} catch (Exception e) {
e.printStackTrace();
}
return ZfbUtils.RETURN_SUCCESS;
}
}
/**

}
//校验签名
if (!ZfbPay.rsaCheckV1(params, ymlParament.getAlipayPublickey())) {
throw new Exception("支付宝回调签名认证失败");
}
//校验一些业务逻辑
//订单是否支付重复
//判断total_amount是否确实为该订单的实际金额(即商户订单创建时的金额)
//.....
// 校验通知中的seller_id(或者seller_email)是否为out_trade_no这笔单据的对应的操作方(有的时候,一个商户可能有多个seller_id/seller_email),
// 验证app_id是否为该商户本身。
if (!params.get("app_id").equals(ymlParament.getAppId())) {
throw new Exception("APPID不对!");
}
}
/**

*/
private static Map<String, String> convertRequestParamsToMap(HttpServletRequest request) {
Map<String, String> retMap = new HashMap<String, String>();
Set<Map.Entry<String, String[]>> entrySet = request.getParameterMap().entrySet();
for (Map.Entry<String, String[]> entry : entrySet) {
String name = entry.getKey();
String[] values = entry.getValue();
int valLen = values.length;
if (valLen == 1) {

}

若不想在支付回调时候去做签名校验,那我们可以主动去查询这笔订单是否支付成功
/*查询订单是否支付成功*/
AlipayTradeQueryResponse response = orderQuery(ac, params.get("out_trade_no"));
if (!"TRADE_SUCCESS".equals(response.getTradeStatus())){
throw new Exception("<==支付宝支付失败==>订单号为【"+ params.get("out_trade_no")+ "】的订单");
}

* @param outTradeNo 订单号
* @return
* @throws AlipayApiException
*/
public static AlipayTradeQueryResponse orderQuery(AlipayClient ac , String outTradeNo) throws Exception {
AlipayTradeQueryModel model = new AlipayTradeQueryModel();
model.setOutTradeNo(outTradeNo);
AlipayTradeQueryResponse response = tradeQuery(ac,model);
if(!response.isSuccess()){
throw new Exception("调用支付宝查询接口失败");
}
return response;
}
/*交易查询接口*/
public static AlipayTradeQueryResponse tradeQuery(AlipayClient ac,AlipayTradeQueryModel model) throws AlipayApiException{
AlipayTradeQueryRequest request = new AlipayTradeQueryRequest();
request.setBizModel(model);
return ac.execute(request);
}
