flutter - 如何将 Stackdriver 与 Flutter 结合使用

Question

我正在开发一个 flutter 应用程序。有什么方法可以直接从 Flutter/Dart 写入数据到 StackDriver。

Answer 1

您可以使用:

https://pub.dev/packages/googleapis

例子:

import 'package:googleapis/logging/v2.dart';
import 'package:googleapis_auth/auth.dart';
import 'package:googleapis_auth/auth_io.dart';

final _credentials = new ServiceAccountCredentials.fromJson(r'''
{
... YOUR CREDENTIALS ....
}
''');

const _SCOPES = const ['https://www.googleapis.com/auth/logging.write'];

clientViaServiceAccount(_credentials, _SCOPES).then((httpClient) {
  var errorReporting = new LoggingApi(httpClient);

  // Resource
  var resource = new MonitoredResource();
  resource.type = 'global';
  resource.labels = {
    'project_id': 'PROJECT_ID',
  };

  // Prepare new log entry.
  LogEntry logEntry = new LogEntry();
  logEntry.logName = "projects/PROJECT_ID/logs/LOG_ID";
  logEntry.jsonPayload = {'message': 'YOUR MESSAGE'};
  logEntry.resource = resource;

  var request = new WriteLogEntriesRequest();
  request.entries = [logEntry];

  errorReporting.entries.write(request).then((_) {
    print('log entry sent');
  });
});

但是，请注意，您需要将您的凭据放在您的 Flutter 应用程序上，“黑客”可以窃取它。因此，最好将日志发送到后端，然后再将其发送到 StackDriver。
