Make your WKWebView happy with NSURLProtocol

nsurlprotocol-webkitsupport's Introduction

NSURLProtocol+WebKitSupport

Note：If you target iOS 11, you can now use WKURLSchemeHandler to avoid this trick! 😆

让 WKWebView 支持 NSURLProtocol

This example project shows a way to use NSURLProtocol with WKWebView, which was not possible before.

Screenshot

Usage

Drag NSURLProtocol+WebKitSupport.h and NSURLProtocol+WebKitSupport.m into your project, then register the scheme for NSURLProtocol to handle:

[NSURLProtocol wk_registerScheme:@"https"];

// You can now use your own NSURLProtocol subclasses as before.
[NSURLProtocol registerClass:[MyAwesomeURLProtocol class]];

To remove the scheme from registery:

[NSURLProtocol wk_unregisterScheme:@"https"];

nsurlprotocol-webkitsupport's Issues

ios10.3 unsupported?

logging: 2017-08-09 15:56:09.732903+0800 WebviewDemo[1022:227643] Could not signal service com.apple.WebKit.Networking: 113: Could not find specified service

请问可以写一个swift 版本吗？现在在使用swift写Hybrid ，想打包成cocopods库

大佬这个可以和WKURLSchemeHandler共同使用吗

我们项目中也使用wk_registerScheme注册 scheme，且注册有多个，有谁遇到过吗？

拦截WKWebView后，WKWebView与原生交互的方法“evaluateJavaScript”就不起作用了

如题，求解

部分网页会无限加载

http://www.meijushe.cc/play/447-1-1.html 可以把这个网址放进去，页面一直在跳动
有没有办法解决这个问题？

请问这个工具可以解决wkwebview的缓存问题吗？

最近初学swift做一个Mac应用，用到了wkwebview，但是遇到一个问题，当打开几个页面后再返回到之前的页面，会重新发送网络请求重载页面，网上查了一下，貌似wkwebview不支持缓存，wkwebview的macOS SDK更加不多，所以想知道这个工具能不能解决这个问题。谢谢！

实际使用时遇到的问题想讨论下.

我想利用WKWebview支持NSURLProtocol后实现类似页面广告屏蔽的功能.
但是实际运用时发现,一旦调用wk_registerScheme:方法注册监听scheme后,一些POST的表单提交就会出现问题.即使在canInitWithRequest:方法中设置对于POST请求的request不处理也不能解决问题.

用代理跟踪请求时发现,未使用NSURLProtocol进行拦截的POST请求中,HTTPBody里包含了表单post的数据.但是使用了NSURLProtocol后,这些请求发送出去的时候没有携带参数.导致请求结果与预想的出现偏差.

如果您有解决方案或者思路,可否一起讨论一下.谢谢~

某些链接会加载失败

这个链接https://h5app-dev.multilotto.com/en/casino/play/chinesenewyearmobile/ （VPN才可以打开）如果使用这种方式会报错 Could not signal service com.apple.WebKit.Networking: 113: Could not find specified service

只能拦截自定义的scheme？可是自定义scheme https不支持的啊

请问有什么办法不影响post 的情况下拦截

ViewController释放后WKWebView还在加载导致奔溃

您好，我使用你的方式注册NSURLProtocol。使用的时候发现有个问题。如果ViewController关闭页面，WKWebView还在加载中，并且在ViewController dealloc中已经把WKWebView UIDelegate和navigationDelegate设为nil并stopLoading 但还是会因为已经释放，地址找不到报以下错误。

错误发生在这里[WKCustomProtocolLoader connectionDidFinishLoading:]
如果我不使用NSURLProtocol 则不会有问题。我想应该是WKCustomProtocolLoader还不完善所以才没有公布NSURLProtocol
