要从Google API获取附件的Ids,你需要使用Flutter框架结合Google提供的API客户端库。以下是实现这一功能的基础概念、步骤和相关代码示例:
google_sign_in
和googleapis
插件来处理认证和API调用。以下是一个简单的示例,展示如何使用Flutter和Google Drive API获取附件的Ids:
import 'package:flutter/material.dart';
import 'package:google_sign_in/google_sign_in.dart';
import 'package:googleapis/drive/v3.dart' as drive;
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(title: Text('Google Drive Attachment IDs')),
body: DriveAttachmentIds(),
),
);
}
}
class DriveAttachmentIds extends StatefulWidget {
@override
_DriveAttachmentIdsState createState() => _DriveAttachmentIdsState();
}
class _DriveAttachmentIdsState extends State<DriveAttachmentIds> {
final GoogleSignIn _googleSignIn = GoogleSignIn(
scopes: [
drive.DriveApi.driveScope,
],
);
List<String> _attachmentIds = [];
@override
void initState() {
super.initState();
_signInAndFetchAttachments();
}
Future<void> _signInAndFetchAttachments() async {
try {
await _googleSignIn.signIn();
final driveApi = drive.DriveApi(_googleSignIn.currentUser.authHeaders);
var files = await driveApi.files.list(q: "mimeType='application/octet-stream'");
setState(() {
_attachmentIds = files.files.map((file) => file.id).toList();
});
} catch (e) {
print("Error: $e");
}
}
@override
Widget build(BuildContext context) {
return ListView.builder(
itemCount: _attachmentIds.length,
itemBuilder: (context, index) {
return ListTile(
title: Text('Attachment ID: ${_attachmentIds[index]}'),
);
},
);
}
}
通过以上步骤和代码示例,你应该能够在Flutter应用中成功获取Google Drive上附件的Ids。
