Swift调用微信支付宝SDK(Swift4.0)

　1.第一步在程序入口注册微信 (支付宝不需要)

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    //向微信终端程序注册第三方应用

     WXApi.registerApp(WX_APPID)

}

　 2.微信支付管理类客户端只负责调用(支付信息什么的都是服务器完成的)

import UIKit

//微信appid

let WX_APPID=""

//AppSecret

let SECRET=""

//微信

class WXApiManager:NSObject,WXApiDelegate {

    static let shared = WXApiManager()

    // 用于弹出警报视图，显示成功或失败的信息()

    private weak var sender:BaseViewController! //(UIViewController)

    // 支付成功的闭包

    private var paySuccessClosure: (() -> Void)?

    // 支付失败的闭包

    private var payFailClosure: (() -> Void)?

    //登录成功

    private var loginSuccessClosure:((_ code:String) -> Void)?

    //登录失败

    private var loginFailClosure:(() -> Void)?

    // 外部用这个方法调起微信支付

    func payAlertController(_ sender:BaseViewController,

                            request:PayReq,

                            paySuccess: @escaping () -> Void,

                            payFail:@escaping () -> Void) {

        // sender 是调用这个方法的控制器，

        // 用于提示用户微信支付结果，可以根据自己需求是否要此参数。

        self.sender = sender

        self.paySuccessClosure = paySuccess

        self.payFailClosure = payFail

        if checkWXInstallAndSupport(){//检查用户是否安装微信

            WXApi.send(request)

        }

    }

    //外部用这个方法调起微信登录

    func login(_ sender:BaseViewController,loginSuccess: @escaping ( _ code:String) -> Void,

               loginFail:@escaping () -> Void){

        // sender 是调用这个方法的控制器，

        // 用于提示用户微信支付结果，可以根据自己需求是否要此参数。

        self.sender = sender

        self.loginSuccessClosure = loginSuccess

        self.loginFailClosure = loginFail

        if checkWXInstallAndSupport(){

            let req=SendAuthReq()

            req.scope="snsapi_userinfo"

            req.state="app"

            WXApi.send(req)

        }

    }

}

extension WXApiManager {

    func onResp(_ resp: BaseResp!) {

        if resp is PayResp {//支付

            if resp.errCode == 0 {

                self.paySuccessClosure?()

            }else{

                self.payFailClosure?()

            }

        }else if resp is SendAuthResp{//登录结果

            let authResp = resp as! SendAuthResp

            var strMsg: String

            if authResp.errCode == 0{

                strMsg="微信授权成功"

            }else{

                switch authResp.errCode{

                case -4:

                    strMsg="您拒绝使用微信登录"

                    break

                case -2:

                    strMsg="您取消了微信登录"

                    break

                default:

                    strMsg="微信登录失败"

                    break

                }

            }

            UIAlertController.showAlertYes(sender, title: "授权结果", message: strMsg, okButtonTitle:"确定", okHandler: { (alert) in

                if authResp.errCode == 0 {

                    self.loginSuccessClosure?(authResp.code)

                }else{

                    self.loginFailClosure?()

                }

            })

        }

    }

}

extension WXApiManager {

    // 检查用户是否已经安装微信并且有支付功能

    private func checkWXInstallAndSupport() -> Bool {

        if !WXApi.isWXAppInstalled() {

            ///这里的弹窗是我写的扩展方法

            UIAlertController.showAlertYes(sender,title:"", message: "微信未安装", okButtonTitle:"确定")

            return false

        }

        if !WXApi.isWXAppSupport() {

            ///这里的弹窗是我写的扩展方法

            UIAlertController.showAlertYes(sender,title:"", message: "当前微信版本不支持支付", okButtonTitle:"确定")

            return false

        }

        return true

    }

}

3. 支付宝管理类客户端只负责调用(支付信息什么的都是服务器完成的)

//支付宝

class AliPayManager:NSObject{

    static let shared = AliPayManager()

    // 用于弹出警报视图，显示成功或失败的信息

    fileprivate weak var sender: UIViewController!

    // 支付成功的闭包

    fileprivate var paySuccessClosure: (() -> Void)?

    // 支付失败的闭包

    fileprivate var payFailClosure: (() -> Void)?

    ///登录成功的闭包

    fileprivate var loginSuccessClosure:((_ auth_code:String) -> Void)?

    ///登录失败的闭包

    fileprivate var loginFailClosure:(() -> Void)?

    // 外部用这个方法调起支付支付

    func payAlertController(_ sender: UIViewController,

                            request:String,

                            paySuccess: @escaping () -> Void,

                            payFail:@escaping () -> Void) {

        // sender 是调用这个方法的控制器，

        self.sender = sender

        //用于提示用户支付宝支付结果，可以根据自己需求是否要此参数。

        self.paySuccessClosure = paySuccess

        self.payFailClosure = payFail

        AlipaySDK.defaultService().payOrder(request, fromScheme:"这里是URL Types配置的URLShcemes",callback:nil)

    }

    //外部用这个方法调起支付宝登录

    func login(_ sender:BaseViewController,withInfo:String,loginSuccess: @escaping (_ str:String) -> Void,loginFail:@escaping () -> Void){

        // sender 是调用这个方法的控制器，

        // 用于提示用户微信支付结果，可以根据自己需求是否要此参数。

        self.sender = sender

        self.loginSuccessClosure = loginSuccess

        self.loginFailClosure = loginFail

        AlipaySDK.defaultService().auth_V2(withInfo:withInfo, fromScheme:"这里是URL Types配置的URLSchemes", callback:nil)

    }

    ///授权回调

    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

        }

        UIAlertController.showAlertYes(sender, title: "授权结果", message: returnMsg, okButtonTitle:"确定", okHandler: { (alert) in

            if returnCode == "9000" {

                let r=result["result"] as! String

                self.loginSuccessClosure?(r)

            }else{

                self.loginFailClosure?()

            }

        })

    }

    //传入回调参数

    func showResult(result:NSDictionary){

        //        9000    订单支付成功

        //        8000    正在处理中

        //        4000    订单支付失败

        //        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 "8000":

//            returnMsg = "正在处理中"

//            break

//        case "4000":

//            returnMsg = "订单支付失败"

//            break

//        case "9000":

//            returnMsg = "支付成功"

//            break

//        default:

//            returnMsg = "订单支付失败"

//            break

//        }

//        UIAlertController.showAlertYes(sender, title: "支付结果", message: returnMsg, okButtonTitle:"确定", okHandler: { (alert) in

//            if returnCode == "9000" {

//                self.paySuccessClosure?()

//

//            }else{

//                self.payFailClosure?()

//            }

//        })

        if returnCode == "9000" {

            self.paySuccessClosure?()

        }else{

            self.payFailClosure?()

        }

    }

}

4.在AppDelegate中回调

// MARK: - 支付回调

extension AppDelegate{

    // iOS 8 及以下请用这个

    func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {

        if url.host == "safepay"{//支付宝

            //支付回调

            AlipaySDK.defaultService().processOrder(withPaymentResult: url, standbyCallback:{ (resultDic) in

                if resultDic != nil{

                    AliPayManager.shared.showResult(result:resultDic! as NSDictionary)

                }

            })

            //授权回调

            AlipaySDK.defaultService().processAuth_V2Result(url, standbyCallback: { (resultDic) in

                if resultDic != nil{

                    AliPayManager.shared.showAuth_V2Result(result:resultDic! as NSDictionary)

                }

            })

            return true

        }else{//微信

            return WXApi.handleOpen(url, delegate:WXApiManager.shared)

        }

    }

    // iOS 9 以上请用这个

    func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool {

        if url.host == "safepay"{//支付宝

            //支付回调

            AlipaySDK.defaultService().processOrder(withPaymentResult: url, standbyCallback:{ (resultDic) in

                if resultDic != nil{

                    AliPayManager.shared.showResult(result:resultDic! as NSDictionary)

                }

            })

            //授权回调

            AlipaySDK.defaultService().processAuth_V2Result(url, standbyCallback: { (resultDic) in

                if resultDic != nil{

                    AliPayManager.shared.showAuth_V2Result(result:resultDic! as NSDictionary)

                }

            })

            return true

        }else{//微信

            return WXApi.handleOpen(url,delegate:WXApiManager.shared)

        }

    }

}

5.支付调用这里拿数据是用SwiftyJSON

1.微信支付

///从服务器拿到生成好的请求参数

let charge=json["charge"]

let req=PayReq()

req.timeStamp=charge["timestamp"].uInt32Value

req.partnerId=charge["partnerid"].stringValue

req.package=charge["package"].stringValue

req.nonceStr=charge["noncestr"].stringValue

req.sign=charge["sign"].stringValue

req.prepayId=charge["prepayid"].stringValue

WXApiManager.shared.payAlertController(self, request: req, paySuccess: {

                           print("支付成功")

                        }, payFail: {

                            print("支付失败")

                        })

2.支付宝支付

///从服务器拿到生成好的请求参数

let orderString=json["charge"]["orderString"].stringValue

                        AliPayManager.shared.payAlertController(self, request:orderString, paySuccess: {

                            print("支付成功")

                        }, payFail: {

                            print("支付失败")

                        })
