Question

我想将 google cloud Vision 连接到我的 flutter 应用程序

这是我的代码

import 'package:dio/dio.dart';

const _apiPREFIX = "https://vision.googleapis.com";


class Server {
  Future<void> postReq() async {
    Response response;
    Dio dio = Dio();
    Map<String, dynamic> data = {
      "requests": [
        {
          "image": {
            "source": {
              "imageUri":
                  "https://image.msscdn.net/images/goods_img/20200729/1530505/1530505_2_500.jpg?t=20210902101946"
            }
          },
          "features": [
            {"type": "LABEL_DETECTION", "maxResults": 1}
          ]
        }
      ]
    };
    try {
      response = await dio.post(
        "$_apiPREFIX/v1/images:asyncBatchAnnotate?key=(my api key)",data: data
      );
      print(response.data.toString());
    } catch (e) {
      print(e);
    }

  }
}

Server server = Server();

也许您应该使用这个 package 来检索身份验证令牌并将其传递到请求中。
