快速入门

安装

你可以使用我们的 AI 辅助设置来安装插件。使用以下命令将 Capgo skills 添加到你的 AI 工具中：

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

然后使用以下 prompt：

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

如果你更想手动设置，请运行以下命令安装插件，并按照下方各平台的说明操作：

npm install @capgo/capacitor-inappbrowser
npx cap sync

导入

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

快速入门：在托管 WebView 中实现托管结账

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.openWebView({
  url: 'https://billing.example.com/checkout',
  toolbarType: 'navigation',
  title: 'Checkout',
});

InAppBrowser.addListener('urlChangeEvent', (event) => {
  if (event.url.includes('/success')) {
    InAppBrowser.close();
  }
});

使用 open() 或者当你想要使用 Safari View Controller 或 Chrome Custom Tabs，而不想嵌入完整的原生 WebView 栈时。

选择浏览器模式

使用 open() 当你想要使用平台浏览器界面时：例如 Android 上的 Chrome Custom Tabs 以及 SFSafariViewController iOS 上的界面。使用 openWebView() 当你的应用需要控制原生 WebView 时：例如自定义尺寸、工具栏、应用消息传递、JavaScript 注入、下载、代理、弹窗、隐藏实例或 UI 层叠。

常见用例

在实时浏览器页面上显示 Ionic UI

使用 Capacitor 在托管的 WebView 后方打开受管 WebView， toBack。这样你的 Ionic UI 就可以在网页内容保持加载的同时，在页面上方进行渲染。通过使用 dispatchInputEvent() 将手势转发给浏览器，以便覆盖层能与页面进行交互。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

const { id } = await InAppBrowser.openWebView({
  url: 'https://example.com/checkout',
  toBack: true,
  transparentBackground: true,
});

await InAppBrowser.dispatchInputEvent({
  id,
  type: 'click',
  x: 160,
  y: 420,
});

await InAppBrowser.bringToFront({ id });

在需要显示浏览器的位置，将相关的应用背景设置为透明。当浏览器位于应用后方时，除非你显式转发，否则原生手势仍由 Capacitor WebView 掌控。

构建部分屏幕浏览器或底部弹窗

设置 height, width, x，以及 y 以便在原生浏览器周围保持 Capacitor 应用的部分可见。在 Android 和 iOS 上，浏览器框架外的触摸操作会透传到底层的 Capacitor WebView。

const bottomGap = 200;

const { id } = await InAppBrowser.openWebView({
  url: 'https://example.com/offers',
  height: window.innerHeight - bottomGap,
  y: 0,
});

await InAppBrowser.updateDimensions({
  id,
  height: window.innerHeight,
  y: 0,
});

适用于微型浏览器、优惠面板、支持组件、基于浏览器的底部弹窗，或任何需要在 Web 内容之外保持原生应用控件可点击的流程。

让 Checkout、Auth 或 Support 会话保持私密

设置 persistWebViewData: false 用于受管理的 WebView，在平台支持的情况下，应避免持久化网站数据。在执行以下操作后调用 clearAllBrowsingData() 注销、切换账号、测试会话，或必须清除默认存储及已打开受管理 WebView 的流程。

const { id } = await InAppBrowser.openWebView({
  url: 'https://example.com/login',
  persistWebViewData: false,
});

await InAppBrowser.clearAllBrowsingData();
await InAppBrowser.close({ id });

在 Android 上，Cookie 使用系统 WebView 的 Cookie 存储，因此 clearAllBrowsingData() 是清理 Cookie 及其他共享浏览器数据的步骤。

随时准备好多个浏览器实例

使用 hidden, hide()，以及 show() 用于预加载或保留多个受管理的 WebView，而无需将每个 WebView 都显示在屏幕上。隐藏的 WebView 仍可接收 executeScript(), postMessage(), setUrl()，以及关闭调用。

const first = await InAppBrowser.openWebView({ url: 'https://example.com/a', hidden: true });
const second = await InAppBrowser.openWebView({ url: 'https://example.com/b', hidden: true });

await InAppBrowser.show({ id: first.id });
await InAppBrowser.hide({ id: first.id });
await InAppBrowser.show({ id: second.id });

嵌入高级 Web App 流程

组合代理规则， handleDownloads, openBlankTargetInWebView, hiddenPopupWindow, enableGooglePaySupport, postMessage()，以及 executeScript() 适用于文档门户、上传流程、支付页面、客服台以及其他需要在不离开应用的情况下进行原生控制的嵌入式 Web 应用。

const { id } = await InAppBrowser.openWebView({
  url: 'https://example.com/portal',
  handleDownloads: true,
  openBlankTargetInWebView: true,
  hiddenPopupWindow: true,
  outboundProxyRules: [
    {
      urlRegex: '^https://example\\.com/api/',
      action: 'delegateToJs',
    },
  ],
});

await InAppBrowser.postMessage({
  id,
  detail: { source: 'app', action: 'refresh' },
});

API 概览

goBack

如果可能，则在 WebView 历史记录中返回上一页

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.goBack();

open

在新窗口中以全屏方式打开 URL；Android 上使用 Chrome Custom Tabs，iOS 上使用 SFSafariViewController

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.open({} as OpenOptions);

clearCookies

清除指定 URL 的 Cookie 当 id 被省略时，将应用于所有已打开的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.clearCookies({} as ClearCookieOptions);

clearAllCookies

清除所有 Cookie 当 id 被省略时，将应用于所有已打开的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.clearAllCookies();

clearCache

清除缓存 当 id 被省略时，将应用于所有已打开的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.clearCache();

clearAllBrowsingData

清除默认存储区和已打开的受管 WebView 中的所有浏览数据，包括 Cookie、缓存、local storage、session storage、IndexedDB、表单数据，以及平台支持时的 HTTP 认证数据。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.clearAllBrowsingData();

getCookies

获取指定 URL 的 Cookie。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.getCookies({} as GetCookieOptions);

close

关闭 webview。 当 id 省略时，关闭当前活动的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.close();

hide

隐藏 webview 而不关闭它。 使用 show() 重新显示。 当 id 若省略，则针对当前活跃的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.hide();

show

显示之前隐藏的 webview。 当 id 若省略，则针对当前活跃的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.show();

sendToBack

将原生浏览器移至 Capacitor 宿主 WebView 后方。当你的 Ionic UI 需要显示在实时浏览器页面之上时，请使用此功能。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.sendToBack({ id: 'webview-id', transparentBackground: true });

bringToFront

将位于宿主 WebView 后方的浏览器移回最前端。当 id 若省略，则针对当前活跃的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.bringToFront({ id: 'webview-id' });

dispatchInputEvent

向托管浏览器发送点击、触摸或滚动事件。坐标相对于浏览器视口，单位为 CSS 像素。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.dispatchInputEvent({
  id: 'webview-id',
  type: 'click',
  x: 160,
  y: 420,
});

openWebView

在带有工具栏的新 webview 中打开 URL，并提供增强功能，例如相机访问、文件访问、监听事件、注入 JavaScript、双向通信等。

JavaScript 接口： 使用此方法打开 webview 时，会自动注入一个提供以下功能的 JavaScript 接口：

• window.mobileApp.close(): 从 JavaScript 关闭 webview
• window.mobileApp.postMessage({detail: {message: "myMessage"}}): 从 webview 向 App 发送消息，detail 对象即为您要发送的数据
• window.mobileApp.takeScreenshot() 何时 allowScreenshotsFromWebPage 为 true 时

不同平台的 Promise 触发时机不同 isPresentAfterPageLoad 已被使用。 Android 会在以下情况解析： { id } 对话框准备好控制后，而 iOS 会在 { id } 创建原生 webview 后立即解析。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.openWebView({} as OpenWebViewOptions);

executeScript

将 JavaScript code 注入到 InAppBrowser 窗口中。 当 id 被省略时，将在所有打开的 webview 中执行。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.executeScript({} as { code: string; id?: string });

postMessage

向 webview (in-app browser) 发送事件。在 webview 的 JavaScript 中，可以使用以下方式监听： window.addEventListener('messageFromNative', listenerFunc). detail 是发送到 webview 的 payload。由于它需要跨越 Capacitor bridge，因此必须是 JSON 可序列化的。 当 id 若省略，则广播到所有已打开的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.postMessage({} as { detail: Record<string, any>; id?: string });

takeScreenshot

将当前 webview 视口捕获为 PNG 截图。 当 id 若省略，则针对当前活跃的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.takeScreenshot();

setUrl

设置 webview 的 URL。 当 id 若省略，则针对当前活跃的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.setUrl({} as { url: string; id?: string });

handleProxyRequest

由以下项使用的内部方法： addProxyHandler() 将代理决策发送回 native 端。 转发原始 phase 回复手动 proxyRequest 监听器时。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.handleProxyRequest({} as {
    requestId: string;
    decision?: ProxyDecision | null;
    response?: ProxyResponse | null;
    webviewId?: string;
    phase?: 'outbound' | 'inbound';
  });

reload

重新加载当前网页。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.reload();

updateDimensions

更新 webview 的尺寸。 允许在运行时更改 webview 的大小和位置。 当 id 若省略，则针对当前活跃的 webview。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.updateDimensions({} as DimensionOptions & { id?: string });

setEnabledSafeTopMargin

在运行时设置 webview 是否启用顶部安全边距。 当 id 若省略，则针对当前的 webview。 在 Web 端，此方法不执行任何操作，且会在不改变布局的情况下直接 resolve。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.setEnabledSafeTopMargin({} as { enabled: boolean; id?: string });

setEnabledSafeBottomMargin

在运行时设置 webview 是否启用安全底部边距。 当 id 若省略，则针对当前的 webview。 在 Web 端，此方法不执行任何操作，且会在不改变布局的情况下直接 resolve。

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.setEnabledSafeBottomMargin({} as { enabled: boolean; id?: string });

openSecureWindow

打开一个用于 OAuth2 身份验证的安全窗口。 对于 Web 端，你需要在重定向页面中包含 code，以便使用 broadcast channel 将重定向 URL 发送给 App。 示例如下：

<html>
<head></head>
<body>
<script>
  const searchParams = new URLSearchParams(location.search)
  if (searchParams.has("code")) {
    new BroadcastChannel("my-channel-name").postMessage(location.href);
    window.close();
  }
</script>
</body>
</html>

对于移动端，你需要一个可以唤起 App 的重定向 URI，示例如下： myapp://oauth_callback/ 并确保已在 App 的 info.plist 中进行注册：

<key>CFBundleURLTypes</key>
<array>
   <dict>
      <key>CFBundleURLSchemes</key>
      <array>
         <string>myapp</string>
      </array>
   </dict>
</array>

以及在 AndroidManifest.xml 文件中：

<activity>
   <intent-filter>
      <action android:name="android.intent.action.VIEW" />
      <category android:name="android.intent.category.DEFAULT" />
      <category android:name="android.intent.category.BROWSABLE" />
      <data android:host="oauth_callback" android:scheme="myapp" />
   </intent-filter>
</activity>

import { InAppBrowser } from '@capgo/capacitor-inappbrowser';

await InAppBrowser.openSecureWindow({} as OpenSecureWindowOptions);
