WebView Crash

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.

如果您更喜欢手动设置，请运行以下命令安装插件，并按照以下平台特定的说明进行操作：

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

设置重启选项在 capacitor.config.ts 这样决定就留在native code即使JavaScript运行时已经崩溃或尚未加载:

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 始终开启的应用程序，用户可能会在几天内保持相同的WebView打开： restartCron 壁钟重启，例如 0 3 * * * 在设备本地时区的每日03:00重启。预定重启写入一个待处理标记， reason: 'periodicRestart'然后Android重新创建宿主活动，iOS重建Capacitor桥视图，所以一个新的 WKWebView 是从native code创建的。

选择一个间隔或cron计划你的产品可以容忍。 restartCron 支持 *，列表、范围和步骤。请勿同时配置两个调度：本机初始化会在配置错误时抛出致命错误。 restartCron 当 restartIntervalMs 大于 0。重启会创建一个新的 JavaScript 运行时，因此请在使用激进调度时保存排队事件、未保存的表单状态和当前导航状态。

手动本机重启

调用 restartWebView() 当当前 JavaScript 运行时决定本机 WebView 应该被替换时，例如在内存密集型工作流之后或进入长时间未attended 会话之前：

await WebViewCrash.restartWebView();

写入一个等待标记 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 Copy to clipboard

API概述

getPendingCrashInfo

返回存储的本机崩溃或重启标记，或 null 当没有待处理的崩溃时。

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

clearPendingCrashInfo

模拟崩溃恢复

await WebViewCrash.clearPendingCrashInfo();

simulateCrashRecovery

Section titled “__CAPGO_KEEP_0__ overview”

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

restartWebView

存储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 存储崩溃元数据从 onRenderProcessGone包括 didCrash 和 rendererPriorityAtExit context:Capgo 营销网站。角色：短 UI 标签或导航项。见于：page trust.astro。消息键 `and` (And)。
• 当平台提供它们时。 webViewWebContentProcessDidTerminate iOS 存储崩溃元数据从
• 手动和预定重启会创建一个新的 WebView。Android 会重新创建宿主活动；iOS 会重建 Capacitor 桥视图。
• 预定重启使用 reason: 'periodicRestart'手动重启使用 reason: 'manualRestart'.
• Web无法检测到真实的渲染器崩溃。Web实现仅使用本地存储模拟行为。
