1：首先是h5不能唤醒微信的事件处理
代理事件如下 逻辑处理如下
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler
- WKNavigationActionPolicy actionPolicy = WKNavigationActionPolicyAllow;
- NSString*urlString = navigationAction.request.URL.absoluteString;
-
- urlString = [urlString stringByRemovingPercentEncoding];
- if ([urlString containsString:@"weixin://wap/pay?"])
- actionPolicy =WKNavigationActionPolicyCancel;
- //解决wkwebview weixin://无法打开微信客户端的处理
- NSURL*url = [NSURL URLWithString:urlString];
- if ([[UIApplication sharedApplication]respondsToSelector:@selector(openURL:options:completionHandler:)])
- [[UIApplication sharedApplication] openURL:url options:@UIApplicationOpenURLOptionUniversalLinksOnly: @NO completionHandler:^(BOOL success)
- ];
- else
- [[UIApplication sharedApplication]openURL:webView.URL];
-
-
- //允许跳转
- decisionHandler(WKNavigationActionPolicyAllow);
2：wkwebview打开微信返回app回调处理
+ NSString *url = navigationAction.request.URL.absoluteString;
+ if ([url containsString:@"https://wx.tenpay.com/cgi-bin/mmpayweb-bin/checkmweb?"])
+ //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:url withIsWebChatURL:NO];
+ [self.view addSubview:h5View];
decisionHandler(WKNavigationActionPolicyCancel);
+ else
+ decisionHandler(WKNavigationActionPolicyAllow);
其中WebChatPayH5VIew为uiwebview 里面主要逻辑为如下
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:@"www.payment.xy189.cn://" forHTTPHeaderField: @"Referer"];
[self.myWebView loadRequest:request];
);
);
