无法访问Chrome无头调试 [英] Can not access Chrome headless debug

问题描述

我正在Karma和Jasmine的无头服务器上运行角度5单元测试.我正在使用无头的chrome来运行测试.

I am running a angular 5 unit test on a headless server in Karma and Jasmine. I am using chrome headless to run the tests.

与-remote-debugging-port = 9223 一起使用时，我无法访问Chrome的调试模式.我尝试在远程Chrome网址中使用 http://35.1.28.84:9223 .

I am not able to access Chrome's debug mode when using with --remote-debugging-port=9223. I tried with http://35.1.28.84:9223 in my remote chrome url.

我确保所有接口都使用 host:'0.0.0.0'进行监听.我确保端口也已打开.

I made sure the all interfaces are listening with host: '0.0.0.0'. I made sure the port was open also.

为什么我不能远程访问chrome的调试器?

How come I am not able to access chrome's debugger remotely?

推荐答案

您需要向chrome提供另一个参数:

There is another parameter you need to supply to chrome:

-远程调试地址= 0.0.0.0

--remote-debugging-address=0.0.0.0

使用给定地址而不是默认环回来接受远程调试连接.应与--remote-debugging-port一起使用.请注意，远程调试协议不会执行任何身份验证，因此，将其公开得太多可能会带来安全风险.

Use the given address instead of the default loopback for accepting remote debugging connections. Should be used together with --remote-debugging-port. Note that the remote debugging protocol does not perform any authentication, so exposing it too widely can be a security risk.
