### FileSDK
|
||||
|
||||
文件上传、下载、打开的统一入口，位于 `com.xuqm.sdk.file`。
|
||||
|
||||
#### 上传
|
||||
|
||||
```kotlin
|
||||
// 从 Uri（文件选择器返回值）上传，自动解析文件名和 MIME 类型
|
||||
val result: FileUploadResult = FileSDK.upload(
|
||||
context = context,
|
||||
uri = uri,
|
||||
onProgress = { progress -> /* 0–100 */ },
|
||||
)
|
||||
|
||||
// 直接上传字节数组（如相机拍照后的 ByteArray）
|
||||
val result = FileSDK.uploadBytes(
|
||||
fileName = "photo.jpg",
|
||||
mimeType = "image/jpeg",
|
||||
bytes = byteArray,
|
||||
onProgress = { progress -> },
|
||||
)
|
||||
|
||||
// 上传 File 对象
|
||||
val result = FileSDK.upload(file = file)
|
||||
```
|
||||
|
||||
`FileUploadResult` 字段：`url`、`thumbnailUrl`、`hash`、`size`、`originalName`、`mimeType`、`ext`
|
||||
|
||||
#### 下载
|
||||
|
||||
```kotlin
|
||||
// 下载存储目标
|
||||
sealed class FileDownloadDestination {
|
||||
data object Sandbox : FileDownloadDestination() // 应用私有目录（无需权限）
|
||||
data object PublicDownloads : FileDownloadDestination() // 系统 Downloads 文件夹
|
||||
}
|
||||
|
||||
// 下载到指定目标，支持通知栏进度
|
||||
val file: File = FileSDK.download(
|
||||
context = context,
|
||||
downloadUrl = "https://example.com/report.pdf",
|
||||
fileName = "report.pdf", // 可选，默认从 URL 推断
|
||||
destination = FileDownloadDestination.PublicDownloads,
|
||||
notificationTitle = "正在下载", // 非 null 时显示通知栏进度条
|
||||
onProgress = { progress -> /* 0–100，同步进度到 H5 或 UI */ },
|
||||
)
|
||||
```
|
||||
|
||||
> **通知栏进度**：设置 `notificationTitle` 后，下载过程中通知栏会显示带进度条的持续通知，完成后自动切换为完成图标。需在 `AndroidManifest.xml` 中声明 `POST_NOTIFICATIONS` 权限（Android 13+）。
|
||||
|
||||
#### 打开文件
|
||||
|
||||
```kotlin
|
||||
// 用系统应用打开本地文件（通过 FileProvider + ACTION_VIEW）
|
||||
FileSDK.openFile(context, file)
|
||||
```
|
||||
|
||||
需在 `AndroidManifest.xml` 中配置 `FileProvider`：
|
||||
|
||||
```xml
|
||||
<provider
|
||||
android:name="androidx.core.content.FileProvider"
|
||||
android:authorities="${applicationId}.fileprovider"

## sdk-webview
|
||||
|
||||
`XWebViewView` 是基于 `android.webkit.WebView` 封装的 Jetpack Compose 组件，内置文件选择、拍照、下载拦截和 JS 通信能力。
|
||||
|
||||
### XWebViewConfig 完整参数
|
||||
|
||||
| 参数 | 类型 | 默认值 | 说明 |
|
||||
|------|------|--------|------|
|
||||
| `url` | String | `""` | 初始加载地址 |
|
||||
| `title` | String | `""` | 页面标题（独立页面模式使用） |
|
||||
| `hideToolbar` | Boolean | `false` | 隐藏独立页面顶栏 |
|
||||
| `hideStatusBar` | Boolean | `false` | 隐藏状态栏 |
|
||||
| `userAgent` | String? | `null` | 自定义 User-Agent |
|
||||
| `injectedJavaScript` | String? | `null` | 页面加载后注入的额外 JS |
|
||||
| `jsBridgeName` | String | `"XWebViewBridge"` | JS 桥接对象名 |
|
||||
| `debugEnabled` | Boolean | `false` | 开启 WebView 远程调试 |
|
||||
| `downloadDestination` | FileDownloadDestination | `Sandbox` | 下载文件存储目标 |
|
||||
| `downloadNotificationTitle` | String? | `null` | 非 null 时通知栏显示下载进度 |
|
||||
| `onMessage` | `(String) -> Unit`? | `null` | H5 发送消息的回调 |
|
||||
|
||||
### 文件选择与拍照
|
||||
|
||||
WebView 内 `<input type="file">` 和 `<input type="file" capture>` 均已内置处理：
|
||||
|
||||
- `accept="image/*"` + `capture` → 调起系统相机，自动申请 `CAMERA` 权限
|
||||
- `accept=".docx,.xlsx"` 等扩展名格式 → 自动映射为正确的 MIME 类型后调起文件选择器
|
||||
- `getUserMedia()` WebRTC 摄像头 → 自动请求 `CAMERA` 权限后授权
|
||||
|
||||
### 下载拦截
|
||||
|
||||
注入的 JS 自动拦截以下两种场景，下载完成后调用 `FileSDK.openFile()` 打开文件：
|
||||
|
||||
- 带 `download` 属性的 `<a>` 标签，或链接以可下载扩展名（`.pdf`、`.zip`、`.docx` 等）结尾
|
||||
- Blob URL（自动转 base64 后传给 native 处理）
|
||||
|
||||
```kotlin
|
||||
XWebViewView(
|
||||
config = XWebViewConfig(
|
||||
url = "https://example.com",
|
||||
downloadDestination = FileDownloadDestination.PublicDownloads, // 存入系统 Downloads
|
||||
downloadNotificationTitle = "正在下载", // 通知栏进度
|
||||
)
|
||||
)
|
||||
```
|
||||
|
||||
### H5 监听下载进度
|
||||
|
||||
H5 页面可通过 `window.addEventListener` 接收下载进度和完成事件：
|
||||
|
||||
```javascript
|
||||
// 下载进度（0–100）
|
||||
window.addEventListener('__xwvDownloadProgress', (e) => {
|
||||
console.log(e.detail.url, e.detail.progress)
|
||||
})
|
||||
|
||||
// 下载完成
|
||||
window.addEventListener('__xwvDownloadDone', (e) => {
|
||||
if (e.detail.success) {
|
||||
console.log('下载成功', e.detail.url)
|
||||
} else {
|
||||
console.error('下载失败', e.detail.error)
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### H5 ↔ Native 消息通信
|
||||
|
||||
```javascript
|
||||
// H5 发消息给 Native（触发 onMessage 回调）
|
||||
window.XWebViewBridge.postMessage(JSON.stringify({ type: 'login', token: '...' }))
|
||||
```
|
||||
|
||||
```kotlin
|
||||
XWebViewConfig(
|
||||
onMessage = { raw ->
|
||||
val json = JSONObject(raw)
|
||||
when (json.optString("type")) {
|
||||
"login" -> { /* 处理登录 */ }
|
||||
}
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
```kotlin
|
||||
// Native 发消息给 H5
|
||||
val controller = getXWebViewController()
|
||||
controller?.postMessageToWeb("window.dispatchEvent(new CustomEvent('nativeMsg', { detail: { key: 'value' } }))")
|
||||
```
