WKWebView和NSURLProtocol无法正常工作 [英] WKWebView and NSURLProtocol not working

问题描述

使用旧的UIWebView时，您可以通过实现自定义NSURLProtocol来捕获请求。我这是为了处理需要身份验证的请求。

When using the old UIWebView you could catch the requests by implementing a custom NSURLProtocol. I us this to handle requests that requires authentication.

我尝试了相同的代码，它不适用于新的WKWebView但我的协议类根本没有被调用。是否有人遇到同样的问题，或者有更好的方法使用WKWebView进行身份验证？

I tried the same code and it doesn't work with the new WKWebView but my protocol class isn't called at all. Is someone experiencing the same problem or is there a better way of doing authentication with the WKWebView?

在没有任何修改的情况下，我在decisionPolicyForNavigationResponse委托函数中得到401响应。我还尝试使用NSURLConnection连接到服务器并使用NSURLConnectionDataDelegate处理身份验证。这有效，但WKWebView没有获取存储的凭据。

Without any modifications I get a 401 response in the decidePolicyForNavigationResponse delegate function. I've also tried connection to the server with a NSURLConnection and handling the authentication with a NSURLConnectionDataDelegate. That works but the stored credentials isn't picked up by the WKWebView.

推荐答案

iOS 11和macOS 10.13的更新答案

从iOS 11开始，可以创建 WKURLSchemeHandler 的子类，并在 WKWebView中注册它配置： - [WKWebViewConfiguration setURLSchemeHandler：forURLScheme：] 。

Updated answer for iOS 11 and macOS 10.13

Since iOS 11 it is possible to create a subclass of WKURLSchemeHandler and register it in the WKWebView configuration: -[WKWebViewConfiguration setURLSchemeHandler:forURLScheme:].

WKWebView 发出请求并将内容呈现在进程外，这意味着您的应用无法听到他们发出的请求。如果您缺少某项功能，现在是时候向Apple打开错误报告和/或增强请求了。

WKWebView makes requests and renders content out-of-process, meaning your app does not hear the requests they make. If you are missing a functionality, now is the time to open a bug report and/or an enhancement request with Apple.

从iOS 10.3 SDK开始， WKWebView 仍然无法使用公共API使用自定义 NSURLProtocol 。

As of iOS 10.3 SDK, WKWebView is still unable to make use of custom NSURLProtocols using public APIs.

有进取心的开发人员找到了一个有趣的方法：
+ [WKBrowsingContextController registerSchemeForCustomProtocol：]
它应该添加提供了一个自定义协议处理方案列表的方案，然后应该使用 NSURLProtocol 。

Enterprising developers have found an interesting method: +[WKBrowsingContextController registerSchemeForCustomProtocol:] It supposedly adds the provided scheme to a list of custom protocol handled schemes and should then work with NSURLProtocol.
