Dart 自颤振后调用云函数时出错

dart flutter

Dart 自颤振后调用云函数时出错,dart,flutter,google-cloud-functions,Dart,Flutter,Google Cloud Functions,我已经创建了云函数，它们可以正常工作（我用postman测试了它们）。当我试图用颤振呼叫他们时，我有一个错误： I/flutter (14755): throwing firebase functions exception I/flutter (14755): caught firebase functions exception I/flutter (14755): INTERNAL I/flutter (14755): Response is missing data field. I/f

我已经创建了云函数，它们可以正常工作（我用postman测试了它们）。当我试图用颤振呼叫他们时，我有一个错误：

I/flutter (14755): throwing firebase functions exception
I/flutter (14755): caught firebase functions exception
I/flutter (14755): INTERNAL
I/flutter (14755): Response is missing data field.
I/flutter (14755): null
I/flutter (14755): null

我补充说

firebase_core: ^0.3.1+1
cloud_functions: ^0.1.2+1

在我的书里

在我的一个dart文件中：

import 'package:youpa/Services/users.services.dart';

[……]

这里是my users.services.dart：

import 'package:cloud_functions/cloud_functions.dart';
import 'package:youpa/Model/user.model.dart';
import 'dart:async';

class UsersService {
  Future<User> searchInAllUsers(String search) async {
    try {
      final dynamic resp = await CloudFunctions.instance.call(
        functionName: 'getUsersBase',
        parameters: <String, dynamic>{
          'txt': search,
          'max': 20,
        },
      );
      print("G : " + resp);
      return resp;
    } on CloudFunctionsException catch (e) {
      print('caught firebase functions exception');
      print(e.code);
      print(e.message);
      print(e.details);
    } catch (e) {
      print('caught generic exception');
      print(e);
    }
  }
}

当我在文本字段中写入或删除一封信时，我在控制台中看到：

I/flutter (14755): throwing firebase functions exception
I/flutter (14755): caught firebase functions exception
I/flutter (14755): INTERNAL
I/flutter (14755): Response is missing data field.
I/flutter (14755): null
I/flutter (14755): null

谢谢，这是事先准备好的。 Jérémy.

尝试使用：

 flutter clean
 cd ios
 pod install

然后再试一次

更新

验证是否正确发送了参数：

    parameters: {
        "data": {
          'txt': search,
          'max': 20,
          },
      },

更新2

通过以下方式修改函数并获取参数：

const { body } = request;
const txt = request.query.txt || body.txt || (body.data && body.data.txt);
const max = request.query.max || body.max || (body.data && body.data.max);

更新3

我想你需要退回这样的东西：

  response.status(200).json({ data: {"your_data_here" }, message: "any_message_if_you_want" });
