This folder contains a variety of code examples for working with
chromedp. The godoc page contains a number of simple examples which
are generally self-contained, while this repository holds more complex examples
which tend to require internet access or external components. 网络接入
Please note that when the chromedp package is being rewritten重写, these examples
may break. Additionally, since these examples are written for specific websites某些网站,
there is a good chance that the current selectors, etc break after the website
they are written against changes.网页修改了
While every effort is made to ensure保证 that these examples are kept up-to-date更新, it is expected that the examples made available here may occassionally break.
To file issues, use the chromedp's issue tracker.
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:

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).
