Electron支持的命令行开关.

您可以在app 模块的ready事件生效之前，使用app.commandLine.appendSwitch将它们附加到您的应用程序的主要脚本中：

const { app } = require('electron')
app.commandLine.appendSwitch('remote-debugging-port', '8315')
app.commandLine.appendSwitch('host-rules', 'MAP * 127.0.0.1')
app.on('ready', () => {
  // 你的代码
})

Supported Chrome Command Line Switches

Command line switches supported by Electron.

You can use app.commandLine.appendSwitch to append them in your app's main script before the ready event of the app module is emitted:

const { app } = require('electron')
app.commandLine.appendSwitch('remote-debugging-port', '8315')
app.commandLine.appendSwitch('host-rules', 'MAP * 127.0.0.1')
app.on('ready', () => {
  // Your code here
})

--ignore-connections-limit=domains

忽略由,分割的domains列表的连接限制.

--ignore-connections-limit=domains

Ignore the connections limit for domains list separated by ,.

--disable-http-cache

禁用HTTP请求的磁盘缓存.

--disable-http-cache

Disables the disk cache for HTTP requests.

--disable-http2

禁用HTTP/2和SPDY/3.1协议.

--disable-http2

Disable HTTP/2 and SPDY/3.1 protocols.

--lang

设置系统语言环境

--lang

Set a custom locale.

--inspect=port and --inspect-brk=port

调试相关的标识, 更多详细信息请查看 Debugging the Main Process指南.

--inspect=port and --inspect-brk=port

Debug-related flags, see the Debugging the Main Process guide for details.

--remote-debugging-port=port

在指定端口开启HTTP远程调试.

--remote-debugging-port=port

Enables remote debugging over HTTP on the specified port.

--disk-cache-size=size

强制磁盘缓存使用的最大磁盘空间（以字节为单位）。

--disk-cache-size=size

Forces the maximum disk space to be used by the disk cache, in bytes.

--js-flags=flags

指定传递给Node JS引擎的标志. 如果你想在主进程中启用flags, 则必须在启动Electron时传递.

$ electron --js-flags="--harmony_proxies --harmony_collections" your-app

访问Node documentation文档或者在终端中运行node --help命令查看可用的标志列表. 此外，还可以运行node --v8-options来查看与Node的V8 JavaScript引擎特定相关的flags列表。

--js-flags=flags

Specifies the flags passed to the Node JS engine. It has to be passed when starting Electron if you want to enable the flags in the main process.

$ electron --js-flags="--harmony_proxies --harmony_collections" your-app

See the Node documentation or run node --help in your terminal for a list of available flags. Additionally, run node --v8-options to see a list of flags that specifically refer to Node's V8 JavaScript engine.

--proxy-server=address:port

使用指定的覆盖系统设置的代理服务器. 这个开关只影响HTTP协议请求, 包括HTTPS和WebSocket请求. 值得注意的是并不是所有的代理服务器都支持HTTPS和WebSocket请求. 代理 URL 不支持用户名和密码认证方式 Chromium 的问题。

--proxy-server=address:port

Use a specified proxy server, which overrides the system setting. This switch only affects requests with HTTP protocol, including HTTPS and WebSocket requests. It is also noteworthy that not all proxy servers support HTTPS and WebSocket requests. The proxy URL does not support username and password authentication per Chromium issue.

--proxy-bypass-list=hosts

指示 Electron绕过给定的分号分隔的代理服务器主机列表. 这个标志只有在与--proxy-server配合使用时才会生效。

例如：

const { app } = require('electron')
app.commandLine.appendSwitch('proxy-bypass-list', '<local>;*.google.com;*foo.com;1.2.3.4:5678')

上面的代码, 除了本地地址(localhost,127.0.0.1等等.), google.com子域名, 包含foo.com后缀的主机地址, 以及任何在1.2.3.4:5678上的地址以外的所有主机都将使用代理服务器.

--proxy-bypass-list=hosts

Instructs Electron to bypass the proxy server for the given semi-colon-separated list of hosts. This flag has an effect only if used in tandem with --proxy-server.

For example:

const { app } = require('electron')
app.commandLine.appendSwitch('proxy-bypass-list', '<local>;*.google.com;*foo.com;1.2.3.4:5678')

Will use the proxy server for all hosts except for local addresses (localhost, 127.0.0.1 etc.), google.com subdomains, hosts that contain the suffix foo.com and anything at 1.2.3.4:5678.

--proxy-pac-url=url

在指定url中使用PAC脚本.

--proxy-pac-url=url

Uses the PAC script at the specified url.

--no-proxy-server

不要使用代理服务器，并始终直接连接. 覆盖传递的任何其他代理服务器标志。

--no-proxy-server

Don't use a proxy server and always make direct connections. Overrides any other proxy server flags that are passed.

--host-rules=rules

以逗号分隔的rules列表，用于控制主机名的映射方式

例如：

• MAP * 127.0.0.1 强制将所有主机名映射到127.0.0.1
• MAP *.google.com proxy 强制所有google.com子域名解析到"proxy".
• MAP test.com [::1]:77 强制"test.com"解析为IPv6环回地址. 也将强制生成的套接字地址端口为77.
• MAP * baz, EXCLUDE www.google.com 把所有地址重新映射到“baz”, 除了"www.google.com".

这些映射适用于网络请求中的端点主机. 网络请求包括TCP连接和直连的主机解析器, 以及HTTP代理连接中的CONNECT方式, 以及在SOCKS代理连接中的端点主机.

--host-rules=rules

A comma-separated list of rules that control how hostnames are mapped.

For example:

• MAP * 127.0.0.1 Forces all hostnames to be mapped to 127.0.0.1
• MAP *.google.com proxy Forces all google.com subdomains to be resolved to "proxy".
• MAP test.com [::1]:77 Forces "test.com" to resolve to IPv6 loopback. Will also force the port of the resulting socket address to be 77.
• MAP * baz, EXCLUDE www.google.com Remaps everything to "baz", except for "www.google.com".

These mappings apply to the endpoint host in a net request (the TCP connect and host resolver in a direct connection, and the CONNECT in an HTTP proxy connection, and the endpoint host in a SOCKS proxy connection).

--host-resolver-rules=rules

与--host-rules类似, 但是这些rules仅适用于主机解析器.

--host-resolver-rules=rules

Like --host-rules but these rules only apply to the host resolver.

--auth-server-whitelist=url

启用了集成身份验证的以逗号分隔的服务器列表。

例如：

--auth-server-whitelist='*example.com, *foobar.com, *baz'

则任何以example.com, foobar.com, baz结尾的url, 都需要考虑集成验证. 没有*前缀，则url必须完全匹配.

--auth-server-whitelist=url

A comma-separated list of servers for which integrated authentication is enabled.

For example:

--auth-server-whitelist='*example.com, *foobar.com, *baz'

then any url ending with example.com, foobar.com, baz will be considered for integrated authentication. Without * prefix the url has to match exactly.

--auth-negotiate-delegate-whitelist=url

需要身份验证的服务器的逗号分隔列表. 没有*前缀则url必须完全匹配.

--auth-negotiate-delegate-whitelist=url

A comma-separated list of servers for which delegation of user credentials is required. Without * prefix the url has to match exactly.

--ignore-certificate-errors

忽略证书相关的错误.

--ignore-certificate-errors

Ignores certificate related errors.

--ppapi-flash-path=path

设置pepper flash插件的path属性.

--ppapi-flash-path=path

Sets the path of the pepper flash plugin.

--ppapi-flash-version=version

设置pepper flash插件的version属性.

--ppapi-flash-version=version

Sets the version of the pepper flash plugin.

--log-net-log=path

启用需要保存的网络日志事件并将其写入path路径下.

--log-net-log=path

Enables net log events to be saved and writes them to path.

--disable-renderer-backgrounding

防止Chromium降低不可见的页面渲染进程的优先级.

这个标识是全局的, 影响所有渲染进程. 如果你只想禁用一个窗口的节流保护，你可以采取playing silent audio.

--disable-renderer-backgrounding

Prevents Chromium from lowering the priority of invisible pages' renderer processes.

This flag is global to all renderer processes, if you only want to disable throttling in one window, you can take the hack of playing silent audio.

--enable-logging

在控制台打印Chromium日志.

这个开关不能用于app.commandLine.appendSwitch, 因为它在用户应用程序加载之前就被解析了, 但是你可以设置ELECTRON_ENABLE_LOGGING环境变量来达到同样的效果.

--enable-logging

Prints Chromium's logging into console.

This switch can not be used in app.commandLine.appendSwitch since it is parsed earlier than user's app is loaded, but you can set the ELECTRON_ENABLE_LOGGING environment variable to achieve the same effect.

--v=log_level

给定默认的最大的有效V-logging等级; 0是默认值。 通常V-logging等级为正值.

这个开关只有在--enable-logging也被传递时才起效.

--v=log_level

Gives the default maximal active V-logging level; 0 is the default. Normally positive values are used for V-logging levels.

This switch only works when --enable-logging is also passed.

--vmodule=pattern

给定每个模块最大的V-logging等级, 覆盖--v设定的值. 例如, my_module=2,foo*=3将改变所有my_module.*和foo*.*源文件的代码的日志等级.

任何包含正斜杠或反斜杠的模式都将针对 整个路径名进行测试，而不仅仅是模块。 例如, */foo/bar/*=2会改变foo/bar目录下源文件的所有代码的日志等级.

这个开关只有在--enable-logging也被传递时才起效.

--vmodule=pattern

Gives the per-module maximal V-logging levels to override the value given by --v. E.g. my_module=2,foo*=3 would change the logging level for all code in source files my_module.* and foo*.*.

Any pattern containing a forward or backward slash will be tested against the whole pathname and not only the module. E.g. */foo/bar/*=2 would change the logging level for all code in the source files under a foo/bar directory.

This switch only works when --enable-logging is also passed.
