Chromium 屏蔽“缺少 Google API 密钥，因此 Chromium 的部分功能将无法使用。”提示 c++

news2024/10/1 6:13:14

新编译的Chromium工程默认gn参数如下:

可以利用gn args --list out/debug >1.txt 导出默认参数

google_api_key
Current value (from the default) = ""
From //google_apis/BUILD.gn:43

Set these to bake the specified API keys and OAuth client
IDs/secrets into your build.

If you create a build without values baked in, you can instead
set environment variables to provide the keys at runtime (see
src/google_apis/google_api_keys.h for details). Features that
require server-side APIs may fail to work if no keys are
provided.

Note that if `use_official_google_api_keys` has been set to true
(explicitly or implicitly), these values will be ignored and the official
keys will be used instead.

google_default_client_id
Current value (from the default) = ""
From //google_apis/BUILD.gn:46

See google_api_key.

google_default_client_secret
Current value (from the default) = ""
From //google_apis/BUILD.gn:49

See google_api_key.

============================================================

第一次运行编译出来的谷歌浏览器效果会提示：

屏蔽缺少 Google API 密钥，因此 Chromium 的部分功能将无法使用。

那么如何屏蔽此功能呢？

一、先根据提示"屏蔽缺少 Google API 密钥，因此 Chromium 的部分功能将无法使用。"找到对应ID，那么如何查找呢？看下面介绍：

1、先去chrome\app\resources\chromium_strings_zh-CN.xtb文件里面搜索该字符串，

<translation id="328888136576916638">缺少 Google API 密钥，因此 Chromium 的部分功能将无法使用。</translation>

2、根据 id="328888136576916638" 去chrome\app\resources\chromium_strings_en-GB.xtb 搜索该ID对应的英文

<translation id="328888136576916638">Google API keys are missing. Some functionality of Chromium will be disabled.</translation>

3、根据标红的英文去搜索chrome\app\google_chrome_strings.grd文件，

Google API keys are missing. Some functionality of Google Chrome will be disabled.

</message>

这样就可以搜到该文字对应的ID = IDS_MISSING_GOOGLE_API_KEYS

【注意字符查找对应关系，其他的内容也是如此查找】

二、内容对应IDS_MISSING_GOOGLE_API_KEYS已经找到，再根据此ID找到c++代码。

chrome\browser\ui\startup\google_api_keys_infobar_delegate.cc

// static
void GoogleApiKeysInfoBarDelegate::Create(
    infobars::ContentInfoBarManager* infobar_manager) {
  infobar_manager->AddInfoBar(
      CreateConfirmInfoBar(std::unique_ptr<ConfirmInfoBarDelegate>(
          new GoogleApiKeysInfoBarDelegate())));
}

GoogleApiKeysInfoBarDelegate::GoogleApiKeysInfoBarDelegate()
    : ConfirmInfoBarDelegate() {
}

infobars::InfoBarDelegate::InfoBarIdentifier
GoogleApiKeysInfoBarDelegate::GetIdentifier() const {
  return GOOGLE_API_KEYS_INFOBAR_DELEGATE;
}

std::u16string GoogleApiKeysInfoBarDelegate::GetLinkText() const {
  return l10n_util::GetStringUTF16(IDS_LEARN_MORE);
}

GURL GoogleApiKeysInfoBarDelegate::GetLinkURL() const {
  return GURL(google_apis::kAPIKeysDevelopersHowToURL);
}

std::u16string GoogleApiKeysInfoBarDelegate::GetMessageText() const {
  return l10n_util::GetStringUTF16(IDS_MISSING_GOOGLE_API_KEYS);
}

int GoogleApiKeysInfoBarDelegate::GetButtons() const {
  return BUTTON_NONE;
}

三、已经找到了GoogleApiKeysInfoBarDelegate类是弹出提示的类。

四、调用的类在chrome\browser\ui\startup\infobar_utils.cc

if (!google_apis::HasAPIKeyConfigured())
GoogleApiKeysInfoBarDelegate::Create(infobar_manager); 处，直接看代码：

void AddInfoBarsIfNecessary(Browser* browser,
                            Profile* profile,
                            const base::CommandLine& startup_command_line,
                            chrome::startup::IsFirstRun is_first_run,
                            bool is_web_app) {
  if (!browser || !profile || browser->tab_strip_model()->count() == 0)
    return;

  // Show the Automation info bar unless it has been disabled by policy.
  bool show_bad_flags_security_warnings = ShouldShowBadFlagsSecurityWarnings();

  content::WebContents* web_contents =
      browser->tab_strip_model()->GetActiveWebContents();
  DCHECK(web_contents);

  if (show_bad_flags_security_warnings) {
#if BUILDFLAG(CHROME_FOR_TESTING)
    if (!IsGpuTest()) {
      ChromeForTestingInfoBarDelegate::Create();
    }
#endif

    if (IsAutomationEnabled())
      AutomationInfoBarDelegate::Create();

    if (base::CommandLine::ForCurrentProcess()->HasSwitch(
            switches::kProtectedAudiencesConsentedDebugToken)) {
      BiddingAndAuctionConsentedDebuggingDelegate::Create(web_contents);
    }

    if (base::CommandLine::ForCurrentProcess()->HasSwitch(
            network::switches::kTestThirdPartyCookiePhaseout)) {
      TestThirdPartyCookiePhaseoutInfoBarDelegate::Create(web_contents);
    }
  }

  // Do not show any other info bars in Kiosk mode, because it's unlikely that
  // the viewer can act upon or dismiss them.
  if (IsKioskModeEnabled())
    return;

  // Web apps should not display the session restore bubble (crbug.com/1264121)
  if (!is_web_app && HasPendingUncleanExit(browser->profile()))
    SessionCrashedBubble::ShowIfNotOffTheRecordProfile(
        browser, /*skip_tab_checking=*/false);

  // These info bars are not shown when the browser is being controlled by
  // automated tests, so that they don't interfere with tests that assume no
  // info bars.
  if (!startup_command_line.HasSwitch(switches::kTestType) &&
      !IsAutomationEnabled()) {
    // The below info bars are only added to the first profile which is
    // launched. Other profiles might be restoring the browsing sessions
    // asynchronously, so we cannot add the info bars to the focused tabs here.
    //
    // We cannot use `chrome::startup::IsProcessStartup` to determine whether
    // this is the first profile that launched: The browser may be started
    // without a startup window (`kNoStartupWindow`), or open the profile
    // picker, which means that `chrome::startup::IsProcessStartup` will already
    // be `kNo` when the first browser window is opened.
    static bool infobars_shown = false;
    if (infobars_shown)
      return;
    infobars_shown = true;

    if (show_bad_flags_security_warnings)
      chrome::ShowBadFlagsPrompt(web_contents);

    infobars::ContentInfoBarManager* infobar_manager =
        infobars::ContentInfoBarManager::FromWebContents(web_contents);

    if (!google_apis::HasAPIKeyConfigured())
      GoogleApiKeysInfoBarDelegate::Create(infobar_manager);

    if (ObsoleteSystem::IsObsoleteNowOrSoon()) {
      PrefService* local_state = g_browser_process->local_state();
      if (!local_state ||
          !local_state->GetBoolean(prefs::kSuppressUnsupportedOSWarning))
        ObsoleteSystemInfoBarDelegate::Create(infobar_manager);
    }

#if !BUILDFLAG(IS_CHROMEOS_ASH)
    if (!is_web_app &&
        !startup_command_line.HasSwitch(switches::kNoDefaultBrowserCheck)) {
      // The default browser prompt should only be shown after the first run.
      if (is_first_run == chrome::startup::IsFirstRun::kNo)
        ShowDefaultBrowserPrompt(profile);
    }
#endif
  }
}

总结：

那么直接把 if (!google_apis::HasAPIKeyConfigured())
GoogleApiKeysInfoBarDelegate::Create(infobar_manager);这段代码屏蔽掉即可。

重新编译运行OK 效果：

GoogleApi主要是谷歌的地图云等服务，可以直接屏蔽。

Cloud Search API
Geolocation API (requires enabling billing but is free to use; you can skip this one, in which case geolocation features of Chrome will not work)
Google Drive API (enable this for Files.app on Chrome OS and SyncFileSystem API)
Safe Browsing API
Time Zone API
Optional
- Admin SDK
- Cloud Translation API
- Geocoding API
- Google Assistant API
- Google Calendar API
- Nearby Messages API
