开始入门
复制一个带有安装步骤和完整 Markdown 指南的设置提示。
Set up this Capacitor plugin in the project.
Use the package manager already used by the project.
Install these package(s): `@capgo/capacitor-webview-crash`
Run the required Capacitor sync/update step after installation.
Read this markdown guide for the full setup steps: https://raw.githubusercontent.com/Cap-go/website/refs/heads/main/apps/docs/src/content/docs/docs/plugins/webview-crash/getting-started.mdx
Use that guide for platform-specific steps, native file edits, permissions, config changes, imports, and usage setup.
If that guide references other docs pages, read them too.
您可以使用我们的 AI 助手设置来安装插件。使用以下命令将 Capgo 技能添加到您的 AI 工具中:
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,请通过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-crashnpx cap sync导入
标题:导入import { WebViewCrash } from '@capgo/capacitor-webview-crash';推荐恢复流程
标题: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
原生自动重启设置重启选项在 capacitor.config.ts 这样,决定就留在原生code中,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 对于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 kiosk屏幕、控制室仪表板、仓库扫描器、POS终端、车队平板电脑和数字标牌。使用 0 3 * * * 墙时钟重启,如 reason: 'periodicRestart', then Android recreates the host activity and iOS rebuilds the Capacitor bridge view so a new WKWebView 然后Android重新创建宿主活动,而iOS重新构建code桥视图,因此从原生code创建一个新的
选择一个时间间隔或计划任务,产品可以容忍。 restartCron 支持 *, 列表、范围和步长。不要同时配置两个计划:本机初始化会在 restartCron 设置且 restartIntervalMs 大于 0时抛出致命配置错误。重启会创建一个新的 JavaScript 运行时,因此在使用激进计划前,请保存排队事件、未保存的表单状态和当前导航状态。
手动本机重启
手动本机重启当当前 JavaScript 运行时决定本机 WebView 应该被替换时调用:例如在内存密集型工作流或进入长时间无人看管会话之前: restartWebView() 复制到剪贴板
await WebViewCrash.restartWebView();Copy to clipboard reason: 'manualRestart', 解决当前调用,然后要求本地 code 创建一个新的 WebView。 Android 重建了宿主活动。 iOS 重建了 Capacitor 桥视图,因此创建了一个新的 WKWebView is 创建了一个新的页面,而不是重新加载当前页面。
API 概述
标题:“API 概述”getPendingCrashInfo
标题:“getPendingCrashInfo”返回存储的本地崩溃或重启标记,或者 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
标题:“clearPendingCrashInfo”清除存储的标记后,完成恢复处理。
await WebViewCrash.clearPendingCrashInfo();simulateCrashRecovery
标题:“simulateCrashRecovery”创建一个虚拟崩溃标记符,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
标题:重新启动 WebView存储手动重启标记并要求本地 code 创建一个新的 WebView。
await WebViewCrash.restartWebView();平台说明
标题:平台说明- Android 存储崩溃元数据从
onRenderProcessGone,包括didCrash和rendererPriorityAtExit当平台提供它们时 - Android 存储崩溃元数据从
webViewWebContentProcessDidTerminate并添加当前应用程序状态(可用时)。 - 手动和计划重启创建一个新的 WebView。Android 重建宿主活动; iOS 重建Capacitor 桥视图。
- 计划重启使用
reason: 'periodicRestart'; 手动重启使用reason: 'manualRestart'. - Web 不检测真实渲染器崩溃。Web 实现仅模拟本地存储的行为。
