kandi X-RAY | headless Summary

headless is a Ruby library typically used in Testing, Functional Testing, Selenium applications. headless has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Headless is the Ruby interface for Xvfb. It allows you to create a headless display straight from Ruby code, hiding the low-level action. It can also capture images and video from the virtual framebuffer. For example, you can record screenshots and screencasts of your failing integration specs. I created it so I can run Selenium tests in Cucumber without any shell scripting. Even more, you can go headless only when you run tests against Selenium. Other possible uses include pdf generation with wkhtmltopdf, or screenshotting. Documentation is available at rubydoc.info.

            Puppeteer , bringing back blank array
            Asked 2022-Apr-02 at 00:08

            I'm trying to grab products from ebay and open them on amazon.

            So far, I have them being searched on amazon but I'm struggling with getting the products selected from the search results.

            Currently its outputting a blank array and im not sure why. Have tested in a separate script without the grabTitles and the for loop. So im guessing there is something in that causing an issue.

            Is there something i am missing here thats preventing the data coming back for prodResults?

            Google OAuth 2.0 failing with Error 400: invalid_request for some client_id, but works well for others in the same project
            Asked 2022-Mar-30 at 14:21

            We have some apps (or maybe we should call them a handful of scripts) that use Google APIs to facilitate some administrative tasks. Recently, after making another client_id in the same project, I started getting an error message similar to the one described in localhost redirect_uri does not work for Google Oauth2 (results in 400: invalid_request error). I.e.,

            Error 400: invalid_request

            You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy for keeping apps secure.

            You can let the app developer know that this app doesn't comply with one or more Google validation rules.

            Request details:

            The content in this section has been provided by the app developer. This content has not been reviewed or verified by Google.

            If you’re the app developer, make sure that these request details comply with Google policies.

            redirect_uri: urn:ietf:wg:oauth:2.0:oob

            How do I get through this error? It is important to note that:

            • The OAuth consent screen for this project is marked as "Internal". Therefore any mentions of Google review of the project, or publishing status are irrelevant
            • I do have "Trust internal, domain-owned apps" enabled for the domain
            • Another client id in the same project works and there are no obvious differences between the client IDs - they are both "Desktop" type which only gives me a Client ID and Client secret that are different
            • This is a command line script, so I use the "copy/paste" verification method as documented here hence the urn:ietf:wg:oauth:2.0:oob redirect URI (copy/paste is the only friendly way to run this on a headless machine which has no browser).
            • I was able to reproduce the same problem in a dev domain. I have three client ids. The oldest one is from January 2021, another one from December 2021, and one I created today - March 2022. Of those, only the December 2021 works and lets me choose which account to authenticate with before it either accepts it or rejects it with "Error 403: org_internal" (this is expected). The other two give me an "Error 400: invalid_request" and do not even let me choose the "internal" account. Here are the URLs generated by my app (I use the ruby google client APIs) and the only difference between them is the client_id - January 2021, December 2021, March 2022.

            Here is the part of the code around the authorization flow, and the URLs for the different client IDs are what was produced on the $stderr.puts url line. It is pretty much the same thing as documented in the official example here (version as of this writing).

            You are running the project via Java 1.8 and add the --add-opens option to the runner. However Java 1.8 does not support it.

            So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.

            Another solution is to find a place where --add-opens is added and remove it. Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine (Maven) and jvmArgs (Gradle)

            WebGL

            WebGL is a cross-platform, open web standard for a low-level 3D graphics API based on OpenGL ES, exposed to ECMAScript via the HTML5 Canvas element. WebGL at it's core is a Shader-based API using GLSL, with constructs that are semantically similar to those of the underlying OpenGL ES API. It follows the OpenGL ES specification, with some exceptions for the out of memory-managed languages such as JavaScript. WebGL 1.0 exposes the OpenGL ES 2.0 feature set; WebGL 2.0 exposes the OpenGL ES 3.0 API.

            Now, with the availability of Selenium Stealth building of Undetectable Scraper using Selenium driven ChromeDriver initiated google-chrome Browsing Context have become much more easier.

            selenium-stealth

            selenium-stealth is a python package selenium-stealth to prevent detection. This programme tries to make python selenium more stealthy. However, as of now selenium-stealth only support Selenium Chrome.

            Components not included in Strapi api response
            Asked 2022-Mar-19 at 16:49

            I decided today that I'm going to use Strapi as my headless CMS for my portfolio, I've bumped into some issues though, which I just seem to not be able to find a solution to online. Maybe I'm just too clueless to actually find the real issue.

            I have set up a schema for my projects that will be stored in Strapi (everything done in the web), but I've had some issues with my custom components, and that is, they are not part of the API responses when I run it through Postman. (Not just empty keys but not included in the response at all). All other fields, that are not components, are filled out as expected.

            At first I thought it might have to do with the permissions, but everything is enabled so it can't be that, I also tried looking into the API in the code, but that logging the answer there didn't include the components either.

            Here is an image of some of the fields in the schema, but more importantly the components that are not included in the response.

            So my question is, do I need to create some sort of a parser or anything in the project to be able to include these fields, or why are they not included?

            Have you tried passing the --headless option to cypress run command? I don't see it in the question, but it does seem as a solution based on some other questions asked here on SO, e.g. this one. You can find this option in documentation here.

            Another solution could be to use an official Cypress Docker image or installing the Xvfb package before running Cypress.

On macOS, the directory will be created when you run XQuartz.app. But since /tmp is cleared on reboot, you will need to open XQuartz.app after a reboot before running Xvfb.
