How can i monitor requests on WKWebview?

如何在WKWebview上监控请求?

I'v tried using NSURLprotocol (canInitWithRequest) but it won't monitor ajax requests (XHR), only navigation requests(document requests)

我尝试过使用NSURLprotocol(canInitWithRequest)但它不会监视ajax请求(XHR),只监视导航请求(文档请求)

Finally I solved it

最后我解决了

Since I don't have control over the web view content, I injected to the WKWebview a java script that include a jQuery AJAX request listener.

由于我无法控制Web视图内容,因此我向WKWebview注入了一个包含jQuery AJAX请求侦听器的java脚本。

When the listener catches a request it sends the native app the request body in the method:

当侦听器捕获请求时,它会在方法中向本机应用程序发送请求正文:

webkit.messageHandlers.callbackHandler.postMessage(data);

The native app catches the message in a delegate called:

本机应用程序在名为的委托中捕获消息:

(void)userContentController:(WKUserContentController *)userContentController didReceiveScriptMessage:(WKScriptMessage *)message

and perform the corresponding actions

并执行相应的操作

here is the relevant code:

这是相关代码:

ajaxHandler.js -

//Every time an Ajax call is being invoked the listener will recognize it and  will call the native app with the request details

$( document ).ajaxSend(function( event, request, settings )  {
    callNativeApp (settings.data);
});

function callNativeApp (data) {
    try {
        webkit.messageHandlers.callbackHandler.postMessage(data);
    }
    catch(err) {
        console.log('The native context does not exist yet');
    }
}

My ViewController delegate are:

我的ViewController委托是:

@interface BrowserViewController : UIViewController <UIWebViewDelegate, WKUIDelegate, WKNavigationDelegate, WKScriptMessageHandler, UIWebViewDelegate>

And in my viewDidLoad(), I'm creating a WKWebView:

在我的viewDidLoad()中,我正在创建一个WKWebView:

WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc]init];
[self addUserScriptToUserContentController:configuration.userContentController];
appWebView = [[WKWebView alloc]initWithFrame:self.view.frame configuration:configuration];
appWebView.UIDelegate = self;
appWebView.navigationDelegate = self;
[appWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString: @"http://#############"]]];

Here is the addUserScriptToUserContentController:

这是addUserScriptToUserContentController:

- (void) addUserScriptToUserContentController:(WKUserContentController *) userContentController{
    NSString *jsHandler = [NSString stringWithContentsOfURL:[[NSBundle mainBundle]URLForResource:@"ajaxHandler" withExtension:@"js"] encoding:NSUTF8StringEncoding error:NULL];
    WKUserScript *ajaxHandler = [[WKUserScript alloc]initWithSource:jsHandler injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:NO];
    [userContentController addScriptMessageHandler:self name:@"callbackHandler"];
    [userContentController addUserScript:ajaxHandler];
}
