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++

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 info bar -->

      <message name="IDS_MISSING_GOOGLE_API_KEYS" desc="Message shown when Google API keys are missing. This message is followed by a 'Learn more' link.">

        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();}
#endifif (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
