安装

您可以使用我们的 AI 助手设置来安装插件。将 Capgo 技能添加到您的 AI 工具中，使用以下命令:

npx skills add https://github.com/Cap-go/capgo-skills --skill capacitor-plugins

然后使用以下提示:

Use the `capacitor-plugins` skill from `Cap-go/capgo-skills` to install the `@capgo/capacitor-webview-crash` plugin in my project.

如果您prefer手动设置，安装插件并运行以下命令并遵循以下平台特定说明:

npm install @capgo/capacitor-webview-crash
npx cap sync

导入

import { WebViewCrash } from '@capgo/capacitor-webview-crash';

推荐恢复流程

尽早在应用启动时附加监听器，以便恢复的运行时可以在用户继续浏览之前反应:

import { WebViewCrash } from '@capgo/capacitor-webview-crash';

await WebViewCrash.addListener('webViewRestoredAfterCrash', async (info) => {
  console.log('Recovered after a WebView crash', info);

  // Rehydrate critical state, reopen the correct screen, or prompt the user to retry.
  await WebViewCrash.clearPendingCrashInfo();
});

await WebViewCrash.addListener('webViewRestoredAfterRestart', async (info) => {
  console.log('Recovered after a native WebView restart', info);
  await WebViewCrash.clearPendingCrashInfo();
});

const pending = await WebViewCrash.getPendingCrashInfo();
// Note: the listener callback may have already cleared the pending marker.
if (pending.value) {
  console.log('Pending crash or restart marker', pending.value);
}

原生自动重启

在 capacitor.config.ts 以便决策在JavaScript运行时崩溃或尚未加载时仍然在原生code中:

import type { CapacitorConfig } from '@capacitor/cli';
import type { WebViewCrashPluginConfig } from '@capgo/capacitor-webview-crash';

const webViewCrash: WebViewCrashPluginConfig = {
  // Enabled by default. Keep this on for long-running apps.
  restartOnCrash: true,

  // Use a 5-field cron schedule in the device local timezone.
  // Do not combine restartCron with an active restartIntervalMs.
  restartCron: '0 3 * * *',

  // Optional delay before restarting after a crash.
  restartAfterCrashDelayMs: 0,
};

const config: CapacitorConfig = {
  plugins: {
    WebViewCrash: webViewCrash,
  },
};

export default config;

使用 restartIntervalMs 适用于 restartCron 的应用程序，用户可能会在同一个 0 3 * * * 中保持打开状态几天： reason: 'periodicRestart', then Android recreates the host activity and iOS rebuilds the Capacitor bridge view so a new WKWebView is created from native code.

的应用程序，例如每天凌晨03:00在设备本地时间区重新启动。预定的重新启动会写入一个待处理标记， restartCron 重新创建宿主活动， *重建 restartCron 视图，因此一个新的 restartIntervalMs 从本机 0创建。

手动原生重启

调用 restartWebView() context:在Appflow比较/迁移营销复制中看到的Appflow迁移步骤2（Appflow Migration Step2）

await WebViewCrash.restartWebView();

复制到剪贴板 reason: 'manualRestart', resolves the current call, then asks native code to create a fresh WebView. Android recreates the host activity. iOS rebuilds the Capacitor bridge view so a new WKWebView , 解决当前调用，然后要求原生__CAPGO_KEEP_0__创建一个新的WebView。Android重新创建宿主活动。iOS重建__CAPGO_KEEP_1__桥接视图，因此一个新的

API overview

getPendingCrashInfo

获取待处理崩溃信息 null 当没有任何待处理的异常时。

const pending = await WebViewCrash.getPendingCrashInfo();
if (pending.value) {
  console.log(pending.value.platform, pending.value.reason);
}

clearPendingCrashInfo

在处理恢复后清除存储的标记。

await WebViewCrash.clearPendingCrashInfo();

simulateCrashRecovery

创建一个虚拟的异常标记，以便 QA 和本地调试可以在不崩溃真实 WebView 的情况下演练恢复路径。

const simulated = await WebViewCrash.simulateCrashRecovery();
console.log(simulated.value);

restartWebView

存储一个手动重启标记，并要求本机 code 创建一个新的 WebView。

await WebViewCrash.restartWebView();

平台说明

• Android从 onRenderProcessGone包括 didCrash 和 rendererPriorityAtExit 当平台提供时
• iOS从 webViewWebContentProcessDidTerminate 并在可用时添加当前应用程序状态
• 手动和预定重启创建一个新的WebView。Android重新创建宿主活动；iOS重建Capacitor桥接视图。
• 预定重启使用 reason: 'periodicRestart'手动重启使用 reason: 'manualRestart'.
• Web无法检测真实的渲染器崩溃。Web实现仅模拟本地存储的行为。
