iOS开发-微信支付宝H5支付跳转原生APP的问题

看我的大白眼
参考
上面的3个博客可以完美解决问题,我只是稍作了修改
支付宝处理
webView拦截 alipay://alipayclient 请求,追加或修改参数 fromAppUrlScheme为你自己的URLScheme值,生成新的NSURL,然后用 [[UIApplication sharedApplication] openURL:] 打开即可。
处。
if ([[URL absoluteString] hasPrefix:@"alipays://"] || [[URL absoluteString] hasPrefix:@"alipay://"]) {
NSString *urlStr = [NSString stringWithFormat:@"%@",URL];
NSMutableString *newUrlStr = [[NSMutableString alloc]initWithString:urlStr];
if ([urlStr containsString:@"fromAppUrlScheme"] && [urlStr containsString:@"alipays"]) {
NSRange range = [newUrlStr rangeOfString:@"alipays"];
[newUrlStr replaceCharactersInRange:range withString:@"你的URLScheme"];
}
NSURL *newUrl = [NSURL URLWithString:newUrlStr];
// NOTE: 跳转支付宝App
BOOL bSucc = [[UIApplication sharedApplication]openURL:newUrl];
// NOTE: 如果跳转失败,则跳转itune下载支付宝App
if (!bSucc) {
}
decisionHandler(WKNavigationActionPolicyCancel);
return ;
}
微信支付处理
主要参考https://www.jianshu.com/p/90db7dfb075c 部分修改了
这里没有让后台处理回调url,iOS自己截取字符串,回调url拼接到了授权域名后面
if ([URL.absoluteString containsString:@"https://wx.tenpay.com/cgi-bin/mmpayweb-bin/checkmweb?"]) {
if ([[UIApplication sharedApplication] canOpenURL:URL]) {
#warning 微信支付链接不要拼接redirect_url,如果拼接了还是会返回到浏览器的
NSArray *array = [URL.absoluteString componentsSeparatedByString:@"&redirect_url="];
//传入的是微信支付链接:https://wx.tenpay.com/cgi-bin/mmpayweb-bin/checkmweb?prepay_id=wx201801291021026cb304f9050743178155&package=3456576571
//这里把webView设置成一个像素点,主要是不影响操作和界面,主要的作用是设置referer和调起微信
WebChatPayH5VIew *h5View = [[WebChatPayH5VIew alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
//url是没有拼接redirect_url微信h5支付链接
[h5View loadingURL:array.firstObject withIsWebChatURL:NO host:array.lastObject];
[self.view addSubview:h5View];
decisionHandler(WKNavigationActionPolicyCancel);
}else{
}
return;
}
这样在微信跳转回来的时候AppDelegate中就可以获取到之前的回调地址
// relaunch with a modified request
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
dispatch_async(dispatch_get_main_queue(), ^{
NSURL *url = [request URL];
NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
//设置授权域名
[request setValue:[NSString stringWithFormat:@"xxx.com://%@",self.host] forHTTPHeaderField: @"Referer"];
[self.myWebView loadRequest:request];
});
});
// NOTE: 9.0以后使用新API接口
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
NSString *urlStr = [NSString stringWithFormat:@"%@",url];
if ([urlStr rangeOfString:@"xxx.com"].location != NSNotFound) {
NSString *newUrlStr = url.host;
[[NSNotificationCenter defaultCenter] postNotificationName:@"WXPayNotification" object:nil userInfo:@{@"url":newUrlStr}];
}
return YES;
}
这样H5控制器接到通知之后,重新加载URL就可以了
