一,前期准备,设置URL Types
- 注册微信支付宝这些就不说了
微信设置
identifier:weixin
(可以固定),后面的URL Schemes
为注册微信的appkey
支付宝设置identifier:alipay
(可以固定),后面的URL Schemes
只要唯一就好了
注意:我这里都是固定的,方便后续去info.plist文件里获取数据方便
- 这里的
weixin
和alipay
固定后续会用的 作为Key来获取URLScheme
Swift版
1.创建管理器
import UIKit
private let URLSchemeWechat = "weixin"
private let URLSchemeAlipay = "alipay"
private var successBlock:(()->())?
private var failBlock:((String)->())?
private var appscheme:[String:String] = [:]
enum HWPayType :Int {
case wx = 0
case zfb = 1
}
class wxPayModel : BaseModel { // 注意:这里的模型需要对应后台返回的 不一定是这些 可以对应修改
/// 预支付订单
var prepayid: String?
/// 商家向财付通申请的商家id
var partnerid: String?
/// 商家根据财付通文档填写的数据和签名
var package: String?
/// 随机串,防重发
var noncestr: String?
/// 商家根据微信开放平台文档对数据做的签名
var sign: String?
/// 时间戳,防重发
var timestamp: Int = 0
/// 由用户微信号和AppID组成的唯一标识,发送请求时第三方程序必须填写,用于校验微信用户是否换号登录
var appid: String?
}

/// 获取单例
public static func shared() -> PaymentManage{
PaymentManage.aliSdkManager = PaymentManage.init()
return PaymentManage.aliSdkManager
}
/// 注册支付系统
func registApp(){
let path = Bundle.main.path(forResource: "Info", ofType: "plist")
let dict = NSDictionary(contentsOfFile: path!)
guard let urlTypes:Array> = dict!["CFBundleURLTypes"] as? Array> else {return}
for item in urlTypes {
let urlName = item["CFBundleURLName"] as? String
if let urlSchemes : Array = item["CFBundleURLSchemes"] as? Array{
let urlScheme = urlSchemes.last ?? ""
if urlName! == URLSchemeWechat {
appscheme[URLSchemeWechat] = urlScheme
// 注册微信
WXApi.registerApp(urlScheme)
}else if urlName == URLSchemeAlipay{
// 保存支付宝的
appscheme[URLSchemeAlipay] = urlScheme
}
}
}
}
// 外部用这个方法调起支付支付
func pay(_ type: HWPayType,
request:Any,
paySuccess: @escaping () -> Void,
payFail:@escaping (String) -> Void) {
successBlock = paySuccess
failBlock = payFail
if type == .zfb {
let newrequest = request as! String
AlipaySDK.defaultService().payOrder(newrequest, fromScheme: appscheme[URLSchemeAlipay]) { (result) in }
} else {

return
}
let model = request as! wxPayModel
let req = PayReq() // 生成支付模型
req.openID = model.appid
req.partnerId = model.partnerid
req.prepayId = model.prepayid
req.package = model.package
req.timeStamp = UInt32(model.timestamp)
req.nonceStr = model.noncestr
req.sign = model.sign
WXApi.send(req) //调起微信
}
}
func noticeopen(_ url: URL) {
if url.host == "safepay" { // 支付宝
AlipaySDK.defaultService().processOrder(withPaymentResult: url as URL?, standbyCallback: { [weak self]
(resultDic) -> Void in
//调起支付结果处理
self?.showResult(result: resultDic! as NSDictionary);
})
} else if url.host!.contains("pay"){ // 微信
WXApi.handleOpen(url, delegate: self)
}
}
/// 授权回调(这里用的是下一种)
func showAuth_V2Result(result:NSDictionary){
// 9000 请求处理成功
// 4000 系统异常
// 6001 用户中途取消
// 6002 网络连接出错
let returnCode:String = result["resultStatus"] as! String
var returnMsg:String = ""
switch returnCode{
case "6001":
returnMsg = "用户中途取消"
break
case "6002":
returnMsg = "网络连接出错"
break
case "4000":
returnMsg = "系统异常"
break
case "9000":
returnMsg = "授权成功"
break
default:
returnMsg = "系统异常"
break
}
HWPrint(returnMsg)

/// 传入回调参数

// 6001 用户中途取消
// 6002 网络连接出错
let returnCode:String = result["resultStatus"] as! String
var returnMsg:String = ""
switch returnCode{
case "6001":
returnMsg = "用户中途取消"
if failBlock == nil {return}
failBlock!(returnMsg)
break
case "6002":
returnMsg = "网络连接出错"
if failBlock == nil {return}
failBlock!(returnMsg)
break
case "8000":
returnMsg = "正在处理中"
if failBlock == nil {return}
failBlock!(returnMsg)
break
case "4000":
returnMsg = "订单支付失败"
if failBlock == nil {return}
failBlock!(returnMsg)
break
case "9000":
if successBlock == nil {return}
successBlock!()
returnMsg = "支付成功"
break
default:
returnMsg = "订单支付失败"
if failBlock == nil {return}
failBlock!(returnMsg)
break
}
HWPrint(returnMsg)
}
}
extension PaymentManage : WXApiDelegate {
func onResp(_ resp: BaseResp!) {
if let payressp:PayResp = resp as? PayResp{
switch payressp.errCode{
case 0:
HWPrint("支付成功")
if successBlock == nil {return}
successBlock!()
break
case -1:
HWPrint(resp.errStr)
if failBlock == nil {return}
failBlock!(resp.errStr ?? "")
break
case -2:
HWPrint("用户中途取消")
if failBlock == nil {return}
failBlock!("用户中途取消")
break;
default:
HWPrint("未知错误")
if failBlock == nil {return}
failBlock!("未知错误")
break;
}
}
}
}
2.使用
- 首先需要在
AppDelegate
里didFinishLaunchingWithOptions
方法里进行注册
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
PaymentManage.shared().registApp() // 注册支付管理者
return true
}
- 其次收到回调信息后通知管理者进行回调
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
let result = UMSocialManager.default().handleOpen(url, sourceApplication: sourceApplication, annotation: annotation)
if (!result) {
// 其他如支付等SDK的回调
PaymentManage.shared().noticeopen(url)
}
return result;
}
- 最后就是使用了
例如:当前是微信支付
if type == .wx {
// 网络请求对应的支付信息 转成模型 <注意模型要转成wxPayModel类型,因为内部用这个类型处理事件的>
PaymentManage.shared().pay(.wx, request: model , paySuccess: {
/// 支付成功要做的事
}, payFail: { (error) in
///error 支付失败的信息
})
} else {
支付宝就直接把json数据传入进去就好了
}

}
}
- (NSMutableDictionary *)appSchemeDict{
if (_appSchemeDict == nil) {
_appSchemeDict = [NSMutableDictionary dictionary];
}
return _appSchemeDict;
}
@end
2.使用
- 在
AppDelegate
的didFinishLaunchingWithOptions
方法中注册
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[HWPayManage shareManager] hw_registerApp];
return YES;
}
- 收到回调后通知管理者
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options {
BOOL result = [[UMSocialManager defaultManager] handleOpenURL:url];
if (!result) {
// 其他如支付等SDK的回调
return [[HWPayManage shareManager] hw_handleUrl:url];
}
return result;
}
- 使用 (注意这里没有提供类型选择, 是根据后台返回的json字段中是否有
info
来判断的)
[[HWPayManage shareManager] hw_payWithOrderMessage:item.data success:^{
/// 支付成功处理逻辑
} fail:^(NSString * _Nonnull error) {
/// 支付失败处理逻辑
}];
总结:如果有分享需要注意,收到回调方法可能会被覆盖这样就收不到支付信息的回调了,需要注意
