This folder contains a variety of code examples for working with
chromedp. Please note that when the chromedp package is being
rewritten, these examples may break. Additionally, since these examples are
written for specific websites, there is a good chance that the current
selectors, etc break after the website they are written against changes.
While every effort is made to ensure that these examples are kept up-to-date,
it is expected that the examples made available here
and working, As this is not a core part of the chromedp project,
You can build and run these examples in the usual Go way:
# retrieve examples
$ go get -u -d github.com/chromedp/examples
# run example <prog>
$ go run $GOPATH/src/github.com/chromedp/examples/<prog>/main.go
# build example <prog>
$ go build -o <prog> github.com/chromedp/examples/<prog> && ./<prog>The following examples are currently available:
| Example | Description |
|---|---|
| click | use a selector to click on an element |
| cookie | set a HTTP cookie on requests |
| eval | evaluate javascript and retrieve the result |
| headers | set a HTTP header on requests |
| keys | send key events to an element |
| logic | more complex logic beyond simple actions |
| pool | use chromedp pool |
| screenshot | take a screenshot of a specific element |
| simple | do a simple google search |
| standalone | use chromedp with a standalone (ie, a "pre-existing" / manually started) chrome instance |
| submit | fill out and submit a form |
| text | extract text from a specific element |
| upload | upload a file on a form |
| visible | wait until an element is visible |
Pull Requests and contributions to this project are encouraged and greatly
welcomed! The chromedp project always needs new examples, and needs talented
developers (such as yourself!) to submit fixes for the existing examples when
they break (for example, when a website's layout/HTML changes).
