java -苹果支付凭证校验

流程:支付由IOS端发起支付,java后台只做支付凭证校验

 

	//苹果官网支付结果验证地址
	private String url = "https://buy.itunes.apple.com/verifyReceipt";
	//苹果官网支付结果验证地址(测试地址)
	private String testUrl = "https://sandbox.itunes.apple.com/verifyReceipt";

IOS支付完后会把支付凭证传到后台来,后台通过支付凭证进行支付结果校验 

	/**
	 * 获取支付结果
	 * mapJsonStr 支付凭证
	 */
	@SuppressWarnings("unchecked")
	public Map getPayResult(String mapJsonStr){
		if(mapJsonStr == null){
			return null; //支付凭证为空
		}
		Map resultDataMap = null;
		try{
			//根据支付凭证到官网查询支付结果
			String payResultStr = processPayment(url, mapJsonStr);

			if (payResultStr == null) {
				//数据异常，请稍后重试
				return null;
			}

			//解析苹果支付返回的参数信息
			Map payResultMap = JSON.parseObject(payResultStr, Map.class);
			log.info("解析苹果支付返回的参数信息 : " + payResultMap);
			Integer status = (Integer)payResultMap.get("status");//只有status ==0才是支付成功
			log.info("苹果支付返回状态 : " + status);
			if(null != status && status == 21007){
				//沙盒测试,调用沙盒测试地址去解析
				payResultStr = processPayment(testUrl, mapJsonStr);
				
				if (payResultStr == null) {
					//数据异常，请稍后重试
					return null;
				}
				//解析苹果支付返回的参数信息
				payResultMap = JSON.parseObject(payResultStr, Map.class);
				status = (Integer)payResultMap.get("status");//只有status ==0才是支付成功

				//获取返回的信息
				String receipt = payResultMap.get("receipt") + "";
				if(payResultStr != null){
