支付宝APP支付（IOS手机端+java后台）版

支付宝APP支付（IOS手机端+java后台）版

0.介绍预览

针对需要在IOS手机上接入原生微信支付场景，调用微信进行支付。如图：


              

 

1.资料准备

1.1 账号注册

打开https://openhome.alipay.com，注册支付宝开放平台开发者账号

1.2 开发者认证

登录，进入开发者中心，进行开发者资质认证，并创建移动应用。

 

1.3 签约应用

创建应用后上传相关资料，上线应用并通过审核。审核通过后点击应用，进行签约，此步骤不能省略，否则或报ISV权限不足。

 

 

1.4 应用配置

打开应用信息，配置一下内容，接口签名可下载支付宝签名验签工具进行生成，生成完成后将公钥复制到平台上。

 

2.Java后台开发

添加依赖

<!-- 支付宝支付依赖 -->

生成统一订单

/**
* account 总金额
* sid 用户id
* desc 节点id
* @param request
* @return
*/
@RequestMapping(value="/pay/alipay/signprams",produces="application/json;charset=utf-8")
@ResponseBody
public String signprams(HttpServletRequest request){
String res = "{code:404}";
try{
String totalAmount = request.getParameter("account");
String sid = request.getParameter("sid");
String nid = request.getParameter("desc");
String subject = "电费充值";
String body = "贵大电费预付费充值";
String prefix = "ALE"+sid+"E";
String out_trade_no = WXRequestUtil.getTradeNo(prefix);

//实例化客户端
AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do

",
AlipayUtil.APPID, AlipayUtil.PRIVATE_KEY, "json", AlipayUtil.CHARSET, AlipayUtil.PUBLIC_KEY, "RSA2");
//实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.trade.app.pay
AlipayTradeAppPayRequest alirequest = new AlipayTradeAppPayRequest();
//SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式(model和biz_content同时存在的情况下取biz_content)。
AlipayTradeAppPayModel model = new AlipayTradeAppPayModel();
model.setPassbackParams(URLEncoder.encode(body.toString()));;  //描述信息  添加附加数据
model.setSubject(subject); //商品标题
model.setOutTradeNo(out_trade_no); //商家订单编号
model.setTimeoutExpress("30m"); //超时关闭该订单时间
model.setTotalAmount(totalAmount);  //订单总金额
model.setProductCode("QUICK_MSECURITY_PAY"); //销售产品码，商家和支付宝签约的产品码，为固定值QUICK_MSECURITY_PAY
alirequest.setBizModel(model);
alirequest.setNotifyUrl("http://pay.gzdxfszx.com/pay/alipay/notify.xs

");  //回调地址
String orderStr = "";
try {
//这里和普通的接口调用不同，使用的是sdkExecute
AlipayTradeAppPayResponse response = alipayClient.sdkExecute(alirequest);
orderStr = response.getBody();
//                System.out.println(orderStr);//就是orderString 可以直接给客户端请求，无需再做处理。
} catch (AlipayApiException e) {
e.printStackTrace();
}

String sign = MD5Encode.encode(out_trade_no);
savePayLog(out_trade_no,totalAmount,sid,body, sign,nid,1);

JSONObject resObj = new JSONObject();
resObj.put("code",ResponseCode.HTTP_SUCCESS);
resObj.put("out_trade_no",out_trade_no);
resObj.put("sign",sign);
resObj.put("orderStr",orderStr);

res = resObj.toJSONString();
}catch (Exception e){
e.printStackTrace();
}
return res;
}

 

异步通知处理

 

@RequestMapping(value="/pay/alipay/notify",produces="application/json;charset=utf-8")
@ResponseBody
public String notify(HttpServletRequest request){
Map requestParams = request.getParameterMap();
System.out.println("支付宝支付结果通知"+requestParams.toString());
//获取支付宝POST过来反馈信息
Map<String,String> params = new HashMap<String,String>();

for (Iterator iter = requestParams.keySet().iterator(); iter.hasNext();) {
String name = (String) iter.next();
String[] values = (String[]) requestParams.get(name);
String valueStr = "";
for (int i = 0; i < values.length; i++) {
valueStr = (i == values.length - 1) ? valueStr + values[i]
: valueStr + values[i] + ",";
}
//乱码解决，这段代码在出现乱码时使用。
//valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");
params.put(name, valueStr);
}
//切记alipaypublickey是支付宝的公钥，请去open.alipay.com

对应应用下查看。
//boolean AlipaySignature.rsaCheckV1(Map<String, String> params, String publicKey, String charset, String sign_type)
try {
//验证签名
boolean flag = AlipaySignature.rsaCheckV1(params, AlipayUtil.PUBLIC_KEY, AlipayUtil.CHARSET, "RSA2");
if(flag){
if("TRADE_SUCCESS".equals(params.get("trade_status"))){
//                    //付款金额
//                    String amount = params.get("buyer_pay_amount");
//                    //支付宝交易号
//                    String trade_no = params.get("trade_no");
//                    //附加数据
//                    String passback_params = URLDecoder.decode(params.get("passback_params"));

//商户订单号
String out_trade_no = params.get("out_trade_no");
updateOrderInfo(out_trade_no,MD5Encode.encode(out_trade_no));
}
}
} catch (AlipayApiException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "success";
}

 

3.IOS客户端开发

导入支付宝开发包

 


添加URL Types

 


在需要调用支付宝的地方实现方法

-(void)aliPay
{
[MBProgressHUD showMessage:@"跳转中，请稍候"];
NSString *appScheme = @"alisdkdemo";

NSString *userUrlStr = [NSString stringWithFormat:@"%@?sid=%@&account=%@&desc=%@", ALI_PREPAY_URL, self.student.sid,self.payJinE,self.student.nid];
NSURL *url = [NSURL URLWithString:userUrlStr];
//     NSLog(@"userUrlStr = %@", userUrlStr);

NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:request];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, NSDictionary *responseObject) {
[MBProgressHUD hideHUD];

//                 NSLog(@"支付宝支付的response = %@", operation.responseString);
NSData *JSONData = [operation.responseString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *userDict = [NSJSONSerialization JSONObjectWithData:JSONData options:NSJSONReadingMutableLeaves error:nil];

NSString *orderString = [userDict objectForKey:@"orderStr"];
self.sign = [userDict objectForKey:@"sign"];
self.ordnum = [userDict objectForKey:@"out_trade_no"];

[[AlipaySDK defaultService] payOrder:orderString fromScheme:appScheme callback:^(NSDictionary *resultDic) {
NSLog(@"reslut = %@",resultDic);
[MBProgressHUD hideHUD];

NSString *resultStatus = [resultDic objectForKey:@"resultStatus"];
if([resultStatus isEqualToString:@"9000"]){
// 支付成功，更新用户信息
[self payDidFinish];
}else{
// 支付失败，
[self setupAlertControllerWithTitle:@"支付宝支付结果" messge:@"本次支付未完成，您可以稍后重试！" confirm:@"好的"];
}

}];
}failure:^(AFHTTPRequestOperation *operation, NSError *error) {
[MBProgressHUD hideHUD];
NSLog(@"发生错误！%@",error);
}];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[queue addOperation:operation];

}
