chromedriver中的浏览器选项
chromedriver中的浏览器选项
There are lots of command lines which can be used with the Google Chrome browser. Some change behavior of features, others are for debugging or experimenting. This page lists the available switches including their conditions and descriptions. Last automated update occurred on 2016-10-20.
| Condition | Explanation |
|---|---|
| --/prefetch:1[1] ⊗ | /prefetch:# arguments to use when launching various process types. It has been observed that when file reads are consistent for 3 process launches with the same /prefetch:# argument, the Windows prefetcher starts issuing reads in batch at process launch. Because reads depend on the process type, the prefetcher wouldn't be able to observe consistent reads if no /prefetch:# arguments were used. Note that the browser process has no /prefetch:# argument; as such all other processes must have one in order to avoid polluting its profile. Note: # must always be in [1, 8]; otherwise it is ignored by the Windows prefetcher. ↪ |
| --/prefetch:2[1] ⊗ | No description ↪ |
| --/prefetch:3[1] ⊗ | No description ↪ |
| --/prefetch:4[1] ⊗ | No description ↪ |
| --/prefetch:5[1] ⊗ | /prefetch:# arguments for the browser process launched in background mode and for the watcher process. Use profiles 5, 6 and 7 as documented on kPrefetchArgument* in content_switches.cc. ↪ |
| --/prefetch:6[1] ⊗ | No description ↪ |
| --/prefetch:8[1] ⊗ | /prefetch:# argument shared by all process types that don't have their own. It is likely that the prefetcher won't work for these process types as it won't be able to observe consistent file reads across launches. However, having a valid prefetch argument for these process types is required to prevent them from interfering with the prefetch profile of the browser process. ↪ |
| --0 ⊗ | Value of the --profiler-timing flag that will disable timing information for chrome://profiler. ↪ |
| --? ⊗ | No description ↪ |
| --accept-resource-provider ⊗ | Flag indicating that a resource provider must be set up to provide cast receiver with resources. Apps cannot start until provided resources. This flag implies --alsa-check-close-timeout=0. ↪ |
| --adaboost ⊗ | No description ↪ |
| --aec-refined-adaptive-filter ⊗ | Enables a new tuning of the WebRTC Acoustic Echo Canceler (AEC). The new tuning aims at resolving two issues with the AEC: https://bugs.chromium.org/p/webrtc/issues/detail?id=5777 https://bugs.chromium.org/p/webrtc/issues/detail?id=5778 TODO(hlundin): Remove this switch when experimentation is over; crbug.com/603821. ↪ |
| --agc-startup-min-volume ⊗ | Override the default minimum starting volume of the Automatic Gain Control algorithm in WebRTC used with audio tracks from getUserMedia. The valid range is 12-255. Values outside that range will be clamped to the lowest or highest valid value inside WebRTC. TODO(tommi): Remove this switch when crbug.com/555577 is fixed. ↪ |
| --aggressive ⊗ | No description ↪ |
| --aggressive-cache-discard ⊗ | No description ↪ |
| --aggressive-tab-discard ⊗ | No description ↪ |
| --allow-cross-origin-auth-prompt ⊗ | Allows third-party content included on a page to prompt for a HTTP basic auth username/password pair. ↪ |
| --allow-data-roaming-by-default ⊗ | If this flag is set, enable data roaming in the cellular network by default upon system start if it's an unmanaged device. This flag is used by Rialto device to obtain device policy during OOBE since the Rialto device has no display and and only connects over cell. ↪ |
| --allow-external-pages ⊗ | Allow access to external pages during layout tests. ↪ |
| --allow-failed-policy-fetch-for-test ⊗ | If this flag is passed, failed policy fetches will not cause profile initialization to fail. This is useful for tests because it means that tests don't have to mock out the policy infrastructure. ↪ |
| --allow-file-access ⊗ | On ChromeOS, file:// access is disabled except for certain whitelisted directories. This switch re-enables file:// for testing. ↪ |
| --allow-file-access-from-files ⊗ | By default, file:// URIs cannot read other file:// URIs. This is an override for developers who need the old behavior for testing. ↪ |
| --allow-hidden-media-playback ⊗ | Allows media playback for hidden WebContents ↪ |
| --allow-http-background-page ⊗ | Allows non-https URL for background_page for hosted apps. ↪ |
| --allow-http-screen-capture ⊗ | Allow non-secure origins to use the screen capture API and the desktopCapture extension API. ↪ |

| --allow-legacy-extension-manifests ⊗ | Allows the browser to load extensions that lack a modern manifest when that would otherwise be forbidden. ↪ |
| --allow-loopback-in-peer-connection ⊗ | Allows loopback interface to be added in network list for peer connection. ↪ |

| --allow-nacl-socket-api[2] ⊗ | Specifies comma-separated list of extension ids or hosts to grant access to TCP/UDP socket APIs. ↪ |
| --allow-no-sandbox-job ⊗ | Enables the sandboxed processes to run without a job object assigned to them. This flag is required to allow Chrome to run in RemoteApps or Citrix. This flag can reduce the security of the sandboxed processes and allow them to do certain API calls like shut down Windows or access the clipboard. Also we lose the chance to kill some processes until the outer job that owns them finishes. ↪ |
| --allow-non-localhost ⊗ | No description ↪ |
| --allow-outdated-plugins ⊗ | Don't block outdated plugins. ↪ |
| --allow-ra-in-dev-mode ⊗ | Allows remote attestation (RA) in dev mode for testing purpose. Usually RA is disabled in dev mode because it will always fail. However, there are cases in testing where we do want to go through the permission flow even in dev mode. This can be enabled by this flag. ↪ |
| --allow-running-insecure-content ⊗ | By default, an https page cannot run JavaScript, CSS or plugins from http URLs. This provides an override to get the old insecure behavior. ↪ |
| --allow-sandbox-debugging ⊗ | Allows debugging of sandboxed processes (see zygote_main_linux.cc). ↪ |
| --allow-silent-push ⊗ | Allows Web Push notifications that do not show a notification. ↪ |

| --alsa-output-device[3] ⊗ | The Alsa device to use when opening an audio stream. ↪ |
| --alsa-output-period-size ⊗ | Size of the ALSA output period in frames. The period of an ALSA output device determines how many frames elapse between hardware interrupts. ↪ |

Implies |kAshCopyHostBackgroundAtBoot| and doesn't make much sense if used in conjunction with |kDisableBootAnimation| (since the transition begins at the same time as the white/grayscale login screen animation). ↪ |
| --ash-copy-host-background-at-boot ⊗ | Copies the host window's content to the system background layer at startup. Can make boot slightly slower, but also hides an even-longer awkward period where we display a white background if the login wallpaper takes a long time to load. ↪ |

It is illegal to use |kDataReductionProxy| or |kDataReductionProxyFallback| switch in conjunction with |kDataReductionProxyHttpProxies|. If the URI omits a scheme, then the proxy server scheme defaults to HTTP, and if the port is omitted then the default port for that scheme is used. E.g. "http://foo.net:80", "http://foo.net", "foo.net:80", and "foo.net" are all equivalent. ↪ |

| --use-file-for-fake-audio-capture ⊗ | Play a .wav file as the microphone. Note that for WebRTC calls we'll treat the bits as if they came from the microphone, which means you should disable audio processing (lest your audio file will play back distorted). The input file is converted to suit Chrome's audio buses if necessary, so most sane .wav files should work. You can pass either <path> to play the file looping or <path>%noloop to stop after playing the file to completion. ↪ |

For determinism virtual time does not advance while there are pending network fetches (i.e no timers will fire). Once all network fetches have completed, timers fire and if the system runs out of virtual time is fastforwarded so the next timer fires immediatley, until the specified virtual time budget is exhausted. ↪ |
| --vmodule ⊗ | 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*.*" ("-inl" suffixes are also disregarded for this matching). Any pattern containing a forward or backward slash will be tested against the whole pathname and not just the module. E.g., "*/foo/bar/*=2" would change the logging level for all code in source files under a "foo/bar" directory. ↪ |
