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

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];
 
 
 
}
