iOS调起微信,qq,支付宝app支付总结

一.调起微信支付

1. 申请应用id见官方文档
2. 需要的资源文件SDK文件包括 libWeChatSDK.a，WXApi.h，WXApiObject.h
3. info中添加申请的微信key,idenfifirer为weixin,urlSchema为申请的key
4. appdelegate中添加如下代码:

    //如果是微信的话 那么- (BOOL)application:(UIApplication *)applicationopenURL:(NSURL *)urlsourceApplication:(NSString *)sourceApplicationannotation:(id)annotation {if([[url absoluteString] hasPrefix:ONEWeiXin]) {[WXApi handleOpenURL:url delegate:self];}//other ...return YES;}//appdelegate 为代理实现下面两个代理方法处理请求和返回
-(void) onReq:(BaseReq*)req {DDLogInfo(@"wx :openid - >%@",req.openID);
}//处理微信回调结果
-(void) onResp:(BaseResp*)resp {if ([resp isKindOfClass:[PayResp class]]) {if (payResponse.errCode == WXSuccess) {//微信SDK支付成功消息NSLog(@"PayResp WXSuccess");//微信SDK支付成功}else {//用户取消微信支付if (payResponse.errCode == WXErrCodeUserCancel) {//微信SDK用户取消微信支付,无需处理NSLog(@"PayResp WXErrCodeUserCancel");}//其他错误else {//微信SDK其他支付错误NSString *eventStr = [NSString stringWithFormat:@"PayResp error other:%d", payResponse.errCode];NSLog(@"%@", eventStr);}}}
}

在微信实际调起代码中加入如下代码:

- (void)launchWxpay {//使用appid注册微信BOOL registerApp = [WXApi registerApp:@"##"];if (!registerApp) {NSLog(@"WXApi registerApp Failed!");}ONEPrePayResponse *prepay = [[ONEPayStore sharedInstance] prePayData];prepay.package = @"Sign=WXPay";PayReq *payRequest      = [[PayReq alloc] init];payRequest.openID       = prepay.appid;payRequest.partnerId    = prepay.partnerid;payRequest.prepayId     = prepay.prepayid;payRequest.nonceStr     = [prepay.noncestr stringValue];payRequest.timeStamp    = [prepay.timestamp intValue];payRequest.package      = prepay.package;payRequest.sign         = [self generateSignWithPay:prepay];BOOL isResult = [WXApi sendReq:payRequest];if (isResult) {//添加事件监听微信支付成功消息[self addNotifications];}else {if (![WXApi isWXAppInstalled]) {NSString *tipMsg = @"您的手机未安装手机微信或微信版本过低，请升级微信后方可使用微信支付";[UIAlertView alertWithCallBackBlock:^(NSInteger buttonIndex) {}title:@""message:tipMsgcancelButtonName:@"我知道了"otherButtonTitles:nil, nil];[self postNotificationWithStatus:ONEPayState_WeiXinPay_NotInstalled];return;}else {//用户手机未安装微信、微信版本太低、微信客户端卡住、WXApi的registerApp的appid参数有误[UIAlertView alertWithCallBackBlock:^(NSInteger buttonIndex) {}title:nilmessage:@"支付繁忙,请稍候再试~"cancelButtonName:@"确定"otherButtonTitles:nil, nil];[self postNotificationWithStatus:ONEPayState_WeiXinPay_Fail];}}
}
//计算签名
- (NSString *)generateSignWithPay:(ONEPrePayResponse *)response
{// 构造参数列表NSMutableDictionary *params = [NSMutableDictionary dictionary];[params setValue:kWebChatKey forKey:@"appid"];[params setValue:response.appkey forKey:@"appkey"];[params setValue:[NSString stringWithFormat:@"%@",response.noncestr] forKey:@"noncestr"];[params setValue:response.package forKey:@"package"];[params setValue:response.partnerid forKey:@"partnerid"];[params setValue:response.prepayid forKey:@"prepayid"];[params setValue:response.timestamp forKey:@"timestamp"];NSArray *keys = [params allKeys];keys = [keys sortedArrayUsingComparator:^NSComparisonResult(NSString *str1, NSString *str2) {return [str1 compare:str2];}];NSMutableString *sig = [NSMutableString string];for (int i = 0; i < [keys count]; ++i) {NSString *key = [keys objectAtIndex:i];NSString *value = [params objectForKey:key];[sig appendString:key];[sig appendString:@"="];[sig appendString:value];[sig appendString:@"&"];}NSString *signStr = [sig substringToIndex:sig.length - 1];return [WeChatPayWay sha1:signStr];
}+ (NSString *)sha1:(NSString *)str
{NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];uint8_t digest[CC_SHA1_DIGEST_LENGTH];CC_SHA1(data.bytes, (unsigned int)data.length, digest);NSMutableString* output = [NSMutableString stringWithCapacity:CC_SHA1_DIGEST_LENGTH * 2];for(int i = 0; i < CC_SHA1_DIGEST_LENGTH; i++){[output appendFormat:@"%02x", digest[i]];}return output;
}

注意package固定值,sign为计算出的结果,大小写一定要对应正确

二.调起QQ支付

1. 已有appname和appkey,appname用于url,app之间跳转,identifier为appname,url为urlschema的内容.添加到info的url中.
2. appdelegate中注册,并在url代理方法中添加返回结果的处理代码,如下:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {/*注册qq钱包支付*/[QQWalletSDK registerQQWalletApplication:ONEQQPay // app idurlScheme:kQQpayURLSchemename:kQQpayAppName];//....
}//处理url#pragma mark -  UIApplicationDelegate
- (BOOL)application:(UIApplication *)applicationopenURL:(NSURL *)urlsourceApplication:(NSString *)sourceApplicationannotation:(id)annotation {//处理qq钱包支付流程[QQWalletSDK QQWalletSDKHanldeApplication:application openURL:url  sourceApplication:sourceApplication annotation:annotation];return YES;}//调用代码
/*开始q钱包支付0 --- 成功1 --- 支付过程中用户取消3 --- 参数错误-11000 --- 用户操作中离线(可能同帐号在其他设备登录)-11001 --- 支付过程中用户取消-11003 --- 参数错误28027608 -- 用户绑卡过程中,手机号码与帐号登记的号码不符合,无法继续 28027201 -- 该订单已经支付66210007 -- 帐号未登录,或者登录已超时*/- (void)launchQQPay {if (![QQWalletSDK isSupportQQWallet]) {[UIAlertView alertWithCallBackBlock:^(NSInteger buttonIndex) {}title:nilmessage:@"请先安装手机QQ"cancelButtonName:@"确定"otherButtonTitles:nil, nil];} else {ONEPrePayResponse *resp = [[ONEPayStore sharedInstance] prePayData];if (!resp.appId || !resp.bargainorId || !resp.token_id || !resp.sig || !resp.nonce) {DDLogInfo(@"qqpay resp: %@", resp);[UIAlertView alertWithCallBackBlock:^(NSInteger buttonIndex) {} title:nil message:@"QQ钱包支付失败,请稍后再试!" cancelButtonName:@"确定" otherButtonTitles:nil, nil];} else {[QQWalletSDK startPayWithAppId:resp.appId bargainorId:resp.bargainorId tokenId:resp.token_id signature:resp.sig nonce:resp.nonce completion:^(QWMessage *message, NSError *error) {/**0 --- 成功1 --- 支付过程中用户取消3 --- 参数错误-11000 --- 用户操作中离线(可能同帐号在其他设备登录)-11001 --- 支付过程中用户取消-11003 --- 参数错误28027608 -- 用户绑卡过程中,手机号码与帐号登记的号码不符合,无法继续28027201 -- 该订单已经支付66210007 -- 帐号未登录,或者登录已超时*/ONEOrderPayStatus status = ONEPayState_default;if (error) {DDLogError(@"%@",[error localizedDescription]);status = PayState_QQPay_PayError;} else {switch (message.code) {case 0:status = PayState_QQPay_PaySuccess;break;case 1:case 11001:status = PayState_QQPay_PayCancel;break;case 3:status = PayState_QQPay_PayParamError;break;case 11000:status = PayState_QQPay_PayOffeline;break;case 28027608:status = PayState_QQPay_PayPhoneNumError;break;case 28027201:status = PayState_QQPay_PayHavePaid;break;case 66210007:status = PayState_QQPay_PayLoginError;default:break;}}[self postNotificationWithStatus:status];}];}}
}

注意bundleid一定要对应对.

三.调起支付宝

1.appdelegate中处理url代码里添加跳转处理代码,这里处理回调

if([[url absoluteString] hasPrefix:AliPay]){//支付宝支付的key,是申请的//如果极简 SDK 不可用,会跳转支付宝钱包进行支付,需要将支付宝钱包的支付结果回传给 SDKif ([url.host isEqualToString:@"safepay"]) {[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {NSLog(@"safepay result = %@",resultDic);}];}if ([url.host isEqualToString:@"platformapi"]){//支付宝钱包快登授权返回 authCode[[AlipaySDK defaultService] processAuthResult:url standbyCallback:^(NSDictionary *resultDic) {NSLog(@"platformapi result = %@",resultDic);}];}}

2.实际调起代码如下

 - (void)launchAliPay {@weakify(self)[[AlipaySDK defaultService] payOrder:prepay.prepaystr fromScheme:prepay.appkey callback:^(NSDictionary *resultDic) {@strongify(self)int completeState = ONEPayState_default;int resCode = [[resultDic objectForKey:@"resultStatus"] intValue];NSString * resultStr = [resultDic objectForKey:@"result"];NSString *trueStr = @"";if(resultStr && [resultStr length] > 0){NSString *subStr = @"&success=";NSRange range = [resultStr rangeOfString:subStr];if(resultStr.length > range.length + 5){//起码大于5以上 才能截取5trueStr = [resultStr substringWithRange:NSMakeRange (range.location+ range.length + 1, 4)];}}if (resCode == 9000 && [trueStr isEqualToString:@"true"])//支付成功{completeState = PayState_Alipay_PaySucess;}else if (resCode == 8000){completeState = PayState_Alipay_PayIng;}else if (resCode == 4000){completeState = PayState_Alipay_PayError;}else if (resCode == 6001){completeState = PayState_Alipay_PayCancel;}else if (resCode == 6002){completeState = PayState_Alipay_NetError;}else {completeState = PayState_Alipay_NotKnow_Error;}[self postNotificationWithStatus:completeState];}];}

支付宝的秘钥等放在服务端,有服务端传递回参数
ps.在实际支付集成中尽量把每一个参数都对应好,很多错误是没有错误日志.
