问题 I am required to use XPaths to select all links on a page, for then my Puppeteer app to click into and perform some actions. I am finding that the method (code below) is getting stuck sometimes and my crawler will be paused. Is there a better/different way of getting all links from an XPath? Or is there something in my code that is incorrect and could be pausing my app's progress? try { links = await this.getLinksFromXPathSelector(state); } catch (e) { console.log("error getting links");

问题 I am working on getting the VS Code debugger to attach to Chrome as part of my regular workflow. I keep Chrome running all the time, and the highly-regarded VS Code Live Server extension opens my project in a new tab, which I like. I would like to be able to attach the VS Code debugger to this instance, but it looks like I have to start Chrome from the command line with sudo /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222 Several questions: Is there

问题 Recently i was working on a web design project, and noticed something odd, after the last Google Chrome update.

问题 I would like to know if opening browser developer tools really affect the application performance in any way. It's not about just considering opening the developer tools in the same window, it can be in a new window or the same window. Also is there any difference in application rendering/performance if developer tool is not opened vs opened state? 回答1: Yes, opening the developer tools of a browser has influence on the page's performance. This is because they observe different aspects of the

问题 I know that Fetch Domain is used for this purpose but I do not know how exactly I can implement it. In Selenium python, I used the following code to enable issuing of requestPaused events. driver.execute_cdp_cmd("Fetch.enable",{}) driver.get('https://www.example.com') But I do not know how can I handle requestPaused event (I need to call one fulfillRequest or continueRequest / continueWithAuth ). As a result, my program stops working. I really appreciate it if anyone could provide me an

问题 I have the following simple component: import React from 'react' import '../css.scss' export default (props) => { let activeClass = props.out ? 'is-active' : '' return ( <div className='hamburgerWrapper'> <button className={'hamburger hamburger--htla ' + activeClass}> <span /> </button> </div> ) } When I look for it in the react dev tools, I see: Is this because I need to extend React component? Do I need to create this as a variable and do so? 回答1: This happens when you export an anonymous

问题 Normally both calls are shown, the pre-flight and the actual request. This is sometimes annoying. Is there a way to hide the pre-flights requests ? Or is there a plugin to filter certain requests based on headers ? 回答1: The quickest way to do this is to filter on -method:OPTIONS . Explanation: all pre-flight requests are via the HTTP OPTIONS method (opposed to POST or GET). This filter says "not method OPTIONS". Note the leading hyphen because if you forget it, you'll only show pre-flight
