微信支付有提供的pod库提供使用，但是只提供了唤起微信app进行支付。但是想要在唤起的时候获取支付结果，无法获取。当然你在分享的时候想获取分享结果也是一个未知数。so，今天来解决一下.
notice:两平台处理方式基本一样
1：支付平台的流程图
微信支付流程图
2：支付闭环图
支付闭环图
3：对于微信支付的封装
3.1注册微信appid和遵循支付宝支付的网页支付结果的代理
- (void)setPaySDKAppIDWithweChat:(NSString *)weChatID delegate:(id<GZIMPayWebAliPayDelegate>) delegate {
[[GZPayConfigURL defaultMannage] configURL];
if (weChatID) {
[WXApi registerApp:weChatID];
self.weCahtPayAppKey = weChatID;
}
self.AliPayHelper = [[MSAlipayHelper alloc] init];
self.WebaliPayDelegate = delegate;
}
注意:这里的GZIMPayWebAliPayDelegate是针对支付宝网页支付的回调结果。
3.2唤起微信支付
/**
唤起微信支付
@param payRequest 唤起微信支付要传入的参数对象，
**自行校验是否为空数据
*/
- (void)WakeupWeChatPay:(GZIMPayPayRequest *)payRequest handler:(GZIMPayInfo *)userInfo weChatResult:(void(^)(GZIMPayErrorCode code,NSString * msg,GZIMPayInfo * userInfo))weChatResult {
self.userInfo = userInfo;
PayReq *request = [[PayReq alloc] init];
request.openID = payRequest.openID;
request.partnerId = payRequest.partnerId;
request.prepayId= payRequest.prepayId;
request.package = payRequest.package;
request.nonceStr= payRequest.nonceStr;
request.timeStamp = [payRequest.timeStamp intValue];
request.sign= payRequest.sign;
// 调用微信
[WXApi sendReq:request];
self.weChatResult = weChatResult;
}
3.3 获取微信支付结果回调
/**
微信支付回调
@param url url
@param weChatResult 处理结果回调
@return bool
*/
- (BOOL)weChatHandleOpenUrl:(NSURL *)url weChatResult:(void(^)(GZIMPayErrorCode code,NSString * msg,GZIMPayInfo * userInfo))weChatResult {
// *****注意这里的block*****
self.weChatDelegateResult = weChatResult;
if ([url.scheme isEqualToString:self.weCahtPayAppKey] && [url.host isEqualToString:@"pay"]) {
return [WXApi handleOpenURL:url delegate:(id<WXApiDelegate>)self];
}
return NO;
}
3.4 唤起支付宝支付
/**
-唤起支付宝支付
@param payOrderString 唤起支付宝要传入的参数，
*/
- (void)WakeupAliPay:(NSString *)payOrderString handlerInfo:(GZIMPayInfo *)userInfo {
if (payOrderString) {
self.userInfo = userInfo;
[self.AliPayHelper WakeupAliPayPay:payOrderString fromScheme:GZPAY_ALIPAY_SCHEME handler:^(NSDictionary *result) {
GZIMPayErrorCode payCode = GZIMPaySuccess;
NSString * msg = @"用户支付成功";
if([@"9000" isEqualToString:[result objectForKey:@"resultStatus"]]) {
payCode = GZIMPaySuccess;
msg = @"用户支付成功";
} else if([@"6001" isEqualToString:[result objectForKey:@"resultStatus"]]) {
payCode = GZIMPayCancle;
msg = @"用户中途取消";
} else {
payCode = GZIMPayFaile;
msg = @"用户支付失败";
}
if (self.WebaliPayDelegate && [self.WebaliPayDelegate respondsToSelector:@selector(GZIMPaySDK:payCode:payMsg:forUserInfo:)]) {
[self.WebaliPayDelegate GZIMPaySDK:self payCode:payCode payMsg:msg forUserInfo:self.userInfo];
}
}];
}
}
3.5 唤起支付宝支付回调结果
/**
支付结果回调
@param resultUrl handelrURL
@param completionBlock 支付结果回调Block
*/
- (void)aliPayHandlerResultURL:(NSURL *)resultUrl standbyCallback:(CompletionSDKBlock)completionBlock {
if ([resultUrl.host isEqualToString:@"safepay"]) {
[self.AliPayHelper aliPayHandlerResultURL:resultUrl standbyCallback:completionBlock];
}
}
3.6 支付结果统一回调
/**
支付结果统一回调
@param url url
@param handler 回调
*/
- (void)GZIMPayHandlerOpenUrl:(NSURL *)url handler:(void(^)(GZIMPayErrorCode code, NSString * msg,GZIMPayInfo* payInfo))handler {
// 支付宝
[self aliPayHandlerResultURL:url standbyCallback:^(NSDictionary *resultDic) {
// 订单支付成功
if([@"9000" isEqualToString:[resultDic objectForKey:@"resultStatus"]]) {
if (handler) {
handler(GZIMPaySuccess,@"用户支付成功",self.userInfo);
}
} else if([@"6001" isEqualToString:[resultDic objectForKey:@"resultStatus"]]) {
// 用户中途取消
if (handler) {
handler(GZIMPayCancle,@"用户中途取消",self.userInfo);
}
} else {
if (handler) {
handler(GZIMPayCancle,@"用户支付失败",self.userInfo);
}
}
}];
// 微信
[self weChatHandleOpenUrl:url weChatResult:^(GZIMPayErrorCode code,NSString * msg, GZIMPayInfo *userInfo) {
if (handler) {
handler(code,msg,userInfo);
}
}];
}
3.7 支付回调代理函数
- (void)onResp:(BaseResp *)resp
{
if([resp isKindOfClass:[PayResp class]]){
NSString *strMsg;
switch (resp.errCode) {
case WXSuccess:
strMsg = @"支付结果：成功！";
NSLog(@"支付成功－PaySuccess，retcode = %d", resp.errCode);
if (self.weChatResult) {
self.weChatResult(GZIMPaySuccess,@"用户支付成功",self.userInfo);
self.weChatResult = nil;
}
if (self.weChatDelegateResult) {
self.weChatDelegateResult(GZIMPaySuccess,@"用户支付成功",self.userInfo);
self.weChatDelegateResult = nil;
}
break;
case WXErrCodeUserCancel:
strMsg = @"支付结果：取消！";
NSLog(@"支付取消－PayCancle，retcode = %d", resp.errCode);
if (self.weChatResult) {
self.weChatResult(GZIMPayCancle,@"用户中途取消",self.userInfo);
self.weChatResult = nil;
}
if (self.weChatDelegateResult) {
self.weChatDelegateResult(GZIMPayCancle,@"用户中途取消",self.userInfo);
self.weChatDelegateResult = nil;
}
break;
default:
strMsg = [NSString stringWithFormat:@"支付结果：失败！retcode = %d, retstr = %@", resp.errCode,resp.errStr];
NSLog(@"错误，retcode = %d, retstr = %@", resp.errCode,resp.errStr);
if (self.weChatResult) {
self.weChatResult(GZIMPayFaile,@"用户支付失败",nil);
self.weChatResult = nil;
}
if (self.weChatDelegateResult) {
self.weChatDelegateResult(GZIMPayFaile,@"用户支付失败",nil);
self.weChatDelegateResult = nil;
}
break;
}
}
}
注意这里的有两个block针对微信支付回调结果返回时.注意3.3步骤里的block。大概原因：由于两个block加载时机不同会被替换，由此引起的不会执行对应的block。
有些地方说的不到位，还请各位看官指正。。。
