wkwebview调起支付宝支付

admin 1月 30, 2021 0

WebView唤起支付宝APP设置:

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
    // 类似 UIWebView 的 -webView: shouldStartLoadWithRequest: navigationType:
    NSString *url = [navigationAction.request.URL.absoluteString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
//     NSLog(@"拦截的url = %@",url);
    if ([url containsString:@"alipay://"]) {//拦截url，截取参数，
        NSString* dataStr= [[url substringFromIndex:23] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
//        NSLog(@"dataStr=%@",dataStr);
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[ NSString stringWithFormat:@"alipay://alipayclient/?%@",[self URLEncodedString:dataStr]]]];// 对参数进行urlencode，拼接上scheme。
    }
    
     WKNavigationActionPolicy actionPolicy = WKNavigationActionPolicyAllow;
     decisionHandler(actionPolicy);
}

encode 方法

- (NSString *)URLEncodedString:(NSString *)url{
    NSString * result = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,(CFStringRef)url,NULL ,CFSTR("!*'();:@&=+$,/?%#[]") ,kCFStringEncodingUTF8));
    return result;
}
