通过 Selenium Chromedriver 自动授予对 Chrome 48 中视频和音频的访问权限

问题描述

我想通过 Chromedriver 功能自动授予对 Chrome 中视频和音频的访问权限.

I would like to automatically grant access to video and audio in Chrome via Chromedriver capabilities.

基于 this(相当老的)答案，我尝试了以下方法:

Based on this (pretty old) answer I tried the following:

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
ChromeOptions options = new ChromeOptions();
Map<String, Object> prefs = new HashMap<>();

// with this chrome still asks for permission
prefs.put("profile.managed_default_content_settings.media_stream", 1);
prefs.put("profile.managed_default_content_settings.media_stream_camera", 1);
prefs.put("profile.managed_default_content_settings.media_stream_mic", 1);

// and this prevents chrome from starting
prefs.put("profile.content_settings.exceptions.media_stream_mic.https://*,*.setting", 1);
prefs.put("profile.content_settings.exceptions.media_stream_mic.https://*,*.last_used", 1);
prefs.put("profile.content_settings.exceptions.media_stream_camera.https://*,*.setting", 1);
prefs.put("profile.content_settings.exceptions.media_stream_camera.https://*,*.last_used", 1);

// and this prevents chrome from starting as well
prefs.put("profile.content_settings.pattern_pairs.https://*,*.media_stream.video", "Allow");
prefs.put("profile.content_settings.pattern_pairs.https://*,*.media_stream.audio", "Allow");

options.setExperimentalOption("prefs", prefs);
capabilities.setCapability(ChromeOptions.CAPABILITY, options);

关于如何正确授予权限的任何想法?

Any ideas on how to grant permissions correctly?

推荐答案

遇到了类似的问题，用这个解决了:

Faced similar issue, solved with this:

ChromeOptions options = new ChromeOptions();
options.addArguments("--use-fake-ui-for-media-stream=1");
driver = new ChromeDriver(options);

您也可以使用此方法更改默认相机:

You can also change default camera using this method:

Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("media.default_video_capture_Device", "\\?\root#media#0002#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global");
options.setExperimentalOption("prefs", prefs);

相机代码可以从设置窗口(使用开发工具检查)或Chrome目录中的首选项文件中获取.

Camera code could be obtained from settings window (inspect with dev tools) or from preferences file in Chrome directory.
