// 1.注册拦截请求的 NSURLProtocol
[NSURLProtocol registerClass:[MSDKDnsHttpMessageTools class]];

// 2.注册scheme
Class cls = NSClassFromString(@"WKBrowsingContextController");
SEL sel = NSSelectorFromString(@"registerSchemeForCustomProtocol:");
if ([cls respondsToSelector:sel]) {
    // 通过http和https的请求，同理可通过其他的Scheme 但是要满足ULR Loading System
    [cls performSelector:sel withObject:@"http"];
    [cls performSelector:sel withObject:@"https"];
}

// 3.使用WKWebView.loadRequest
[self.wkWebView loadRequest:request];
