怎么防止网站被注册机,昆明网站建设多少钱,湛江网站制作建设,广州建设信息网以前NSURLProtocol可以直接拦截UIWebView#xff0c;后面升级成WKWebView发现拦截不到了
有细心爱研究的老铁发现了 [WKBrowsingContextController registerSchemeForCustomProtocol:] 这个函数的存在
所以还是可以拦截的

有细心爱研究的老铁发现了 [WKBrowsingContextController registerSchemeForCustomProtocol:] 这个函数的存在
所以还是可以拦截的
直接上步骤
1.在控制器或者你喜欢的地方注册NSURLProtocol(调用以下代码)
Class cls NSClassFromString(WKBrowsingContextController);SEL sel NSSelectorFromString(registerSchemeForCustomProtocol:);if ([(id)cls respondsToSelector:sel]) {[(id)cls performSelector:sel withObject:http];[(id)cls performSelector:sel withObject:https];}[NSURLProtocol registerClass:[CustomProtocol class]];
2.在你自定义的NSURLProtocol类中实现拦截 (BOOL)canInitWithRequest:(NSURLRequest *)request{NSString *abstring request.URL.absoluteString;if ([abstring containsString:你喜欢的标记]) {return YES;}return NO;
} (NSURLRequest *)canonicalRequestForRequest:(NSURLRequest *)request
{return request;
}
3.在你自定义的NSURLProtocol类中拦截后替换请求的内容以下以图片为例
- (void)startLoading{NSString *urlPathString super.request.URL.absoluteString;if ([urlPathString containsString:你喜欢的标记]) {urlPathString [urlPathString stringByReplacingOccurrencesOfString:你喜欢的标记 withString:你喜欢的标记2];}NSData *imageData [NSData dataWithContentsOfURL:[NSURL URLWithString:urlPathString]];NSMutableDictionary *header [NSMutableDictionary dictionary];header[Content-Length] [NSString stringWithFormat:%ld,imageData.length];NSHTTPURLResponse *response [[NSHTTPURLResponse alloc] initWithURL:self.request.URLstatusCode:200 HTTPVersion:1.1 headerFields:header];//回调[self.client URLProtocol:self didReceiveResponse:response cacheStoragePolicy:NSURLCacheStorageAllowed];[self.client URLProtocol:self didLoadData:imageData];[self.client URLProtocolDidFinishLoading:self];}- (void)stopLoading{NSLog(stop);
}
