這兩個的解決思路都是要在下面這個方法中先攔截相應的url，再單獨處理

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler;

支付寶攔截到的url樣式如下：

支付寶：alipay://alipayclient/?{"dataString":"h5_route_token="bf7ace48916875f26c94fba6f62226ef"&is_h5_route="true"","requestType":"SafePay","fromAppUrlScheme":"alipays"}

微信：weixin://wap/pay...

具體代碼如下：

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler{

NSURL *URL = navigationAction.request.URL;

NSString * urlStr = [[URL absoluteString] stringByRemovingPercentEncoding];

if ([urlStr containsString:@"weixin://wap/pay"] || [urlStr containsString:@"alipay://alipayclient"]) {

[[UIApplication sharedApplication] openURL:navigationAction.request.URL];

decisionHandler(WKNavigationActionPolicyCancel);

}

else{

// 在發送請求之前，決定是否跳轉

decisionHandler(WKNavigationActionPolicyAllow);

}

}
