类: CommandLine

类: CommandLine​

操作Chromium读取的应用程序的命令行参数

Process: Main
This class is not exported from the 'electron' module. 它只能作为 Electron API 中其他方法的返回值。

下面的例子展示了如何检查—disable-gpu标志是否设置。

const{ app }=require('electron')

app.commandLine.hasSwitch('disable-gpu')

For more information on what kinds of flags and switches you can use, check out the Command Line Switches document.

实例方法​

commandLine.appendSwitch(switch[, value])​

• switch string - A command-line switch, without the leading --.
• value string (optional) - 给开关设置的值.

通过可选的参数 value 给 Chromium 中添加一个命令行开关。

[!NOTE] This will not affect process.argv. The intended usage of this function is to control Chromium's behavior.

const{ app }=require('electron')

app.commandLine.appendSwitch('remote-debugging-port','8315')

commandLine.appendArgument(value)​

• valuestring - 要追加到命令行的参数.

在Chromium的命令行中附加一个参数。 参数会被正确引用。 无论附加顺序如何,切换将在参数之前进行。

如果你正在追加一个参数,如--switch=value, 请考虑使用appendSwitch('switch', 'value')

const{ app }=require('electron')

app.commandLine.appendArgument('--enable-experimental-web-platform-features')

[!NOTE] This will not affect process.argv. The intended usage of this function is to control Chromium's behavior.

commandLine.hasSwitch(switch)​

• switch string - 命令行开关.

返回boolean - 命令行开关是否打开。

const{ app }=require('electron')

app.commandLine.appendSwitch('remote-debugging-port','8315')
const hasPort = app.commandLine.hasSwitch('remote-debugging-port')
console.log(hasPort)// true

commandLine.getSwitchValue(switch)​

• switch string - 命令行开关.

返回 string - 命令行开关值。

This function is meant to obtain Chromium command line switches. It is not meant to be used for application-specific command line arguments. For the latter, please use process.argv.

const{ app }=require('electron')

app.commandLine.appendSwitch('remote-debugging-port','8315')
const portValue = app.commandLine.getSwitchValue('remote-debugging-port')
console.log(portValue)// '8315'

[!NOTE] When the switch is not present or has no value, it returns empty string.

commandLine.removeSwitch(switch)​

• switch string - 命令行开关.

从Chromium命令行中移除指定的选项。

const{ app }=require('electron')

app.commandLine.appendSwitch('remote-debugging-port','8315')
console.log(app.commandLine.hasSwitch('remote-debugging-port'))// true

app.commandLine.removeSwitch('remote-debugging-port')
console.log(app.commandLine.hasSwitch('remote-debugging-port'))// false

[!NOTE] This will not affect process.argv. The intended usage of this function is to control Chromium's behavior.
