kandi X-RAY | headlessChrome Summary

headlessChrome is a Go library typically used in Devops, Continuous Deployment, Docker applications. headlessChrome has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Support only for Ubuntu on Docker for now. Mac appears to not be working. . A go package for working with headless Chrome. Run interactive JavaScript commands on pages with go and Chrome without a GUI. Includes a few helpful functions out of the box to query and click selector paths by their classes, divs, or html content. You could use this package to click buttons and scrape content on/from a website as if you were a browser, or to render pages that wouldn't be supported by other things like phantomjs or casperjs. Especially useful for sites that use EmberJS, where the content is rendered by javascript after the HTML payload is delivered. An example project that does some simple things with a Makefile and Dockerfile is in the examples directory. To run Chrome headless with docker, check out examples/docker/main.go as well as examples/docker/Makefile. When in that directory, you can do make test to build and run the container with the example app inside. You will see the source of httpbin.org displayed at the end of the build and run. By default, we startup with the bare minimum flags necessary to start headless chrome and open a javascript console. If you want more flags, like a resolution size, or a custom User-Agent, you can specify it by replacing the Args variable. Just be sure to append to it so you don't kill the default flags... Change the path to Chrome by simply setting the headlessChrome.ChromePath variable. Find the full list in the docs. Please send pull requests! It would be good to have support for more operating systems or more handy helpers to run more commonly used javascript code easily. Adding support for other operating systems should be as simple as checking the platform type and changing the ChromePath variable's default value.

QUESTION

Selenium 4.x execute "Page.addScriptToEvaluateOnNewDocument" properly

Asked 2022-Jan-21 at 14:48

I'm having a strange issue where I really cannot find a solution. My production website needs some testing and of course bot checking is enabled (not naming it).

Under my tests after using "Page.addScriptToEvaluateOnNewDocument", the result is not what I would expect.

If I visit the website directly in the current tab of Chromium, it won't pass the bot checks.
If I manually open a new tab and visit the website, it passes the bot checks.

At first I thought the scripts are not being executed in the current tab, however checking things that I overwrite shows that they are.

Using this little script I've taken from puppeteer is a PASS in both tabs:

Make sure you are using express.urlencoded({ extended: true }) middleware, as shown in the documentation otherwise req.body will be undefined.

The output of console.log(req.body.device) you posted is probably the result of outdated code running, because that is what you would normally get from running console.log(req). I've tried running your code and the console output works correctly https://www.anyfiddle.com/p/robalb/sih511dv

Also this is not relevant to the question, but you can get rid of the javascript code in your template by changing the type of the form button from type="text" to type="submit" like this

ANSWER

Answered 2021-Mar-16 at 15:03

When it says it can't find the Chrome binary, it's not talking about chromedriver. It's talking about the actual chrome browser. Those are two different things.

In addition to having the location of chromedriver on your PATH, you also need to have the location of chrome on your PATH. I don't know what's in the base docker image, but it might be that it doesn't have chrome installed.

Puppeteer QuerySelector - TypeError: Cannot read property 'textContent' of null

Asked 2021-Jan-25 at 06:52

Trying to scrape some data about vulnerabilities using Nodejs and Puppeteer, ran into an issue where some properties are showing as null or empty, but running the SelectorQuery in the browser works ( Version 87.0.4280.88 (x86_64) ). below is a snippet that produces the issues.

For the date that the vulnerability is patched where the selector path is 'div.patched' is where it gives a null pointer error but for the rest of the values, it works perfect so I am not sure what is the issue because I am following the same logic

...

ANSWER

Answered 2021-Jan-25 at 06:52

Sections with not-patched issues have no elements with 'div.patched' selector, they have 'div.not-patched' instead. You can chek if node.querySelector('.patched') is null and then return any value for timePatched or use node.querySelector('.not-patched').textContent.

For example, replace:
