Uploading Files
The Web component supports file uploading on a frontend page. You can use onShowFileSelector() to process file upload requests sent from a frontend page.
In the following example, when a user clicks the Upload button on the frontend page, the application receives a file upload request through onShowFileSelector(), which carries the path of the local file to be uploaded.
- Application code:
// xxx.ets
import web_webview from '@ohos.web.webview';
@Entry
@Component
struct WebComponent {
controller: WebController = new WebController()
build() {
Column() {
// Load the local.html page.
Web({ src: $rawfile('local.html'), controller: this.controller })
.onShowFileSelector((event) => {
// Set the path of the local file to be uploaded.
let fileList: Array<string> = [
'xxx/test.png',
]
if (event) {
event.result.handleFileList(fileList)
}
return true;
})
}
}
}
- Code of the local.html page:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Document</title>
</head>
<body>
<!-- Click the Upload button -->
<input type="file" value="file"></br>
</body>
</html>
