一、微信支付
1.注册账号并申请app支付功能
公司需要到微信开放品台进行申请app支付功能 , 获得appid和微信支付商户号(mch_id)和API秘钥(key) 、 Appsecret(secret),开发中用到的,很重要
• appid:appid是微信公众账号或开放平台APP的唯一标识,在公众平台申请公众账号或者在开放平台申请APP账号后,微信会自动分配对应的appid,用于标识该应用。可
在微信公众平台-->开发者中心查看,商户的微信支付审核通过邮件中也会包含该字段值。
• 微信支付商户号:商户申请微信支付后,由微信支付分配的商户收款账号。
• API密钥: 交易过程生成签名的密钥,仅保留在商户系统和微信支付后台,不会在网络中传播。商户妥善保管该Key,切勿在网络中传输,不能在其他客户端中存储,保证
key不会被泄漏。商户可根据邮件提示登录微信商户平台进行设置。也可按一下路径设置:微信商户平台(pay.weixin.qq.com)-->账户设置-->API安全-->密钥设置
• App secret : AppSecret是APPID对应的接口密码,用于获取接口调用凭证access_token时使用。
2.搭建工程并配置
a.导入微信支付的SDK
b.设置URL Scheme
项目-->Info-->RUL Types,添加一个URL SChemes,内容为自己商户的APPID,如下图:
b. 设置微信白名单
3.微信支付流程
在集成微信支付之前应先了解微信支付的整个流程,微信支付整体流程图如下:
步骤1:用户在商户APP中选择商品,提交订单,选择微信支付。
步骤2:商户后台收到用户支付单,调用微信支付统一下单接口。
步骤3:统一下单接口返回正常的prepay_id,再按签名规范重新生成签名后,将数据传输给APP。参与签名的字段名为appId,partnerId,prepayId,nonceStr,timeStamp,package。
注意:package的值格式为Sign=WXPay
步骤4:商户APP调起微信支付。
步骤5:商户后台接收支付通知。
步骤6:商户后台查询支付结果。
3.代码实现具体流程
a.请求接口,生成商户订单
请求后台接口,获取调取微信支付所需的关键参数:partnerid、prepayid、package、sign、timestamp、noncestr
b.注册APPID
[WXApi registerApp:self.wxAppID];//与URL Type中设置的保持一致
c.调起微信支付PayReq *request = [[PayReq alloc] init];
request.openID = self.wxAppKey;
request.partnerId = parterId;
request.prepayId = prePayId;
request.package = package;
request.nonceStr = nonceStr;
request.timeStamp = [timestamp intValue];
request.sign = sign;
if (![WXApi sendReq:request]) {
//微信调起支付失败
}
d.支付结果回调
-(void)onResp:(BaseResp*)resp{
if ([respisKindOfClass:[PayRespclass]]){
PayResp*response=(PayResp*)resp;
switch(response.errCode){
caseWXSuccess:
//服务器端查询支付通知或查询API返回的结果再提示成功
NSlog(@"支付成功");
break;
default:
NSlog(@"支付失败,retcode=%d",resp.errCode);
break;
}
}
}
二、支付宝支付
1.支付宝SDK集成
a.将支付宝的SDK及bundle文件拖入工程
b. 导入依赖库
c.设置URL Schemes
这里设置的URL Scheme必须与payOrder方法中的Scheme保持一致
d.设置白名单
在info.plist 文件中如下设置
2.代码实现
a.生成订单信息及签名
这一步可以通过后台生成订单,直接返回订单字符串,或者移动端自己实例化一个订单对象,并生成订单字符串
//将商品信息赋予AlixPayOrder的成员变量
Order *order = [[Order alloc] init];
order.partner = partner;
order.seller = seller;
order.tradeNO = @"123456"; //订单ID(由商家自行制定)
order.productName = @"太空杯"; //商品标题
order.productDescription = @"耐摔的太空杯"; //商品描述
order.amount = [NSString stringWithFormat:@"%.2f",0.01]; //商品价格
order.notifyURL = @"http://www.lanou3g.com"; //回调URL
order.service = @"mobile.securitypay.pay";
order.paymentType = @"1";
order.inputCharset = @"utf-8";
order.itBPay = @"30m";
order.showUrl = @"m.alipay.com";
//应用注册scheme,在AlixPayDemo-Info.plist定义URL types
NSString *appScheme = @"xiaohange";
//将商品信息拼接成字符串
NSString *orderSpec = [order description];
NSLog(@"orderSpec = %@",orderSpec);
//获取私钥并将商户信息签名,外部商户可以根据情况存放私钥和签名,只需要遵循RSA签名规范,并将签名字符串base64编码和UrlEncode
id<DataSigner> signer = CreateRSADataSigner(privateKey);
NSString *signedString = [signer signString:orderSpec];
//将签名成功字符串格式化为订单字符串,请严格按照该格式
NSString *orderString = nil;
if (signedString != nil) {
orderString = [NSString stringWithFormat:@"%@&sign=\"%@\"&sign_type=\"%@\"",
orderSpec, signedString, @"RSA"];
//[[AlipaySDK defaultService] payOrder:orderString fromScheme:appScheme callback:^(NSDictionary *resultDic) {
// NSLog(@"reslut = %@",resultDic);
//}];
}
b.调起支付宝支付
[[AlipaySDK defaultService] payOrder:orderString fromScheme:@"669SDKAliPay" callback:^(NSDictionary *dict) {
if (dict) {
NSLog(@"%@",dict);
NSInteger statusCode = [dict[@"resultStatus"] integerValue];
NSString *msg = [NSString stringValue:dict[@"memo"]];
if (statusCode == 9000) {
[self performSelector:@selector(paymentSuccess) withObject:self.tradeNo afterDelay:0.25f];
}
else if (statusCode == 6001) {
[self performSelector:@selector(paymentCancel) withObject:self.tradeNo afterDelay:0.25f];
}
else {
[self performSelector:@selector(paymentErrorWithMessage:) withObject:msg afterDelay:0.25f];
}
}
}];

1.在调用后台接口,生成订单成功后调用一下代码:
[[WanPaymentData instance] setDelegate:self];
[WanPaymentData instance].paymentType = paymentType;
[[WanPaymentData instance] requestPaymentURLWithResult:dict];
2.遵守协议并实现代理方法:
#pragma mark --<WanPaymentDataDelegate>
- (void)paymentSuccess{
[self removeFromSuperview];
if (self.paySuccessBlock) {
self.paySuccessBlock();
}
}
- (void)paymentCancel{
[PPUIUtils showStateInWindow:@"您已放弃付款"];
}
- (void)paymentResultWithError:(NSError *)error{
NSString *msg = [error localizedDescription];
[PPUIUtils showStateInWindow:msg];
}
3.在AppDelegate添加以下代码
-(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{
if ([url.host isEqualToString:@"safepay"]) {
return [[WanPaymentData instance] handleOpenURL:[NSURL URLWithString:url.absoluteString]];
}
return [WXApi handleOpenURL:url delegate:[WanPaymentData instance]];
}
-(BOOL)application:(UIApplication *)app openURL:(NSURL *)url sourceApplication:(nullable NSString *)sourceApplication annotation:(nonnull id)annotation{
if ([url.host isEqualToString:@"safepay"]) {
return [[WanPaymentData instance] handleOpenURL:[NSURL URLWithString:url.absoluteString]];
}
return [WXApi handleOpenURL:url delegate:[WanPaymentData instance]];
}
-(BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options{
if ([url.host isEqualToString:@"safepay"]) {
return [[WanPaymentData instance] handleOpenURL:[NSURL URLWithString:url.absoluteString]];
}
return [WXApi handleOpenURL:url delegate:[WanPaymentData instance]];
}
