ios - WKWebview 无法正确加载某些网站
<p><p>我需要将各种各样的网站 URL(来自网络服务)加载到 WKWebview 中。</p>
<p>一些网站表现良好，只需将 URL 中的“http”替换为“https”即可正常加载:</p>
<pre><code>http://www.yahoo.com/news -> loads blank
**https://www.yahoo.com/news -> loads OK!!**
URLs without the https:// prefix will NOT load at all.
http://www.google.com -> blank
**https://www.google.com -> Loads OK!!!**
http://www.bbc.co.uk/news (no .plist Exception) -> blank
https://www.bbc.co.uk/news (no .plist Exception) -> blank
http://www.bbc.co.uk/news (WITH .plist Exception) -> blank
https://www.bbc.co.uk/news (WITH .plist Exception) -> blank
</code></pre>
<p>(我在 MAC OS 浏览器上粘贴了 <a href="https://www.bbc.co.uk/news" rel="noreferrer noopener nofollow">https://www.bbc.co.uk/news</a>，并被重定向到 <a href="https://www.bbc.co.uk/news" rel="noreferrer noopener nofollow">https://www.bbc.co.uk/news</a>，所以我也尝试了:)</p>
<pre><code>https://www.bbc.com/news (WITH .plist Exception) -> Images and text are loaded in a messy, unformatted, basic way.
http://www.bbc.com/news (WITH .plist Exception) -> Images and text are loaded in a messy, unformatted, basic way.
https://www.bbc.com/news (WITHOUT .plist Exception) -> blank
http://www.bbc.com/news (WITHOUT .plist Exception) -> blank
</code></pre>
<p>其他网址的行为与 BBC 或上面的 Yahoo 示例类似。</p>
<p>这是我在 .plist 文件中使用的那种异常。</p>
<p>这是我的代码:</p>
<pre><code>- (void)viewDidLoad{
;
CGRect wkFrame = _wios10container.frame;
NSLog(@"WPVC - viewDidLoad, wkFrame: %@",NSStringFromCGRect(wkFrame));
WKWebViewConfiguration *wkConfiguration = [ init];
_webviewIOS10 = [ initWithFrame:_wios10container.frame configuration:wkConfiguration];
_webviewIOS10.navigationDelegate = self;
;
}
</code></pre>
<p><strong>我的问题是:</strong> </p>
<ol>
<li>如何正确加载 BBC 等网站？</li>
<li>如何让我的应用在不需要大量列表的情况下加载任何 URL
异常(exception)情况？</li>
<li>如果我将 NSAppTransportSecurity.NSAllowsArbitraryLoads 设置为 YES，该应用程序可以正常工作，但我根本不喜欢这样。
为了安全和 App Store 的批准，我有什么替代方案？</li>
</ol></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>执行此操作的更可靠的方法是使用 WKNavigationDelegate 并在您的情况下评估 URL。为了处理一个巨大的列表(没有更多关于该列表的知识)，我会根据它进行正则表达式评估。您还可以根据需要创建重定向策略。</p>
<p>例如:</p>
<pre><code>class WebNavigationHandler: NSObject, WKNavigationDelegate {
func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Swift.Void) {
//Based on the navigation action decide what to do.
if canINavigate {
decisionHandler(.allow)
} else {
decisionHandler(.cancel)
}
}
func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Swift.Void) {
// Base on the navigationResponse
if canINavigate {
decisionHandler(.allow)
} else {
decisionHandler(.cancel)
}
}
}
let webview = WKWebView()
webview.navigationDelegate = WebNavigationHandler()
</code></pre>
<p>希望它能回答你的问题。</p></p>
