import "github.com/J-Siu/go-dtquery/dq"

See root.go for code sample.

DT_Url

As Chrome/Chromium name(key) of the devtool url in http//localhost:9222/json/version may change overtime, starting dq v1.2.0, AFTER calling dq.Get(host, port), the devtool url can be access directly with dq.DT_Url:

devtools := dq.Get(host, port, true)
devtool_url := dq.DT_Url()
# # or
# devtool_url := devtools.DT_Url

Current support devtools url json name:

• WsUrl (Chrome < 140)
• WebSocketDebuggerUrl (Chrome >= 140)

Command Line Demo

1. Close running Chrome. Start Chrome with following option:

   chrome --remote-debugging-port=9222
   

   Or Chromium with the same option.

2. Run

   go run main.go [-r <hostname/ip>] [-p <port>]
