如何在 Flutter [1] 中使用这种格式从 API 获取数据：https ://i.stack.imgur.com/V6hVH.png

Answer 1

基本上，您的 API 端点正在请求正文。
在颤振中，你可以使用包http: ^0.12.1

import 'package:http/http.dart' as http;

final api = 'https://data.geoiq.io/dataapis/v1.0/covid/locationcheck';
final response = http.post(api, body: { "key": string, "latlngs": array });

如果 API 端点需要身份验证令牌。例如 Bearer 令牌然后你可以使用

final token = 'YOUR TOKEN';

final response = http.post(api, body: { "key": string, "latlngs": array }, headers: {
  'Authorization': 'Bearer $token',
});

请在下面找到示例请求。

import json as js
import requests
body =    {"latlngs": [
            [
                12.967444,
                77.498775

            ],
            [
                14.656773,
                77.627936
            ],
            [
                19.200027,
                72.970519
            ],
            [
                12.962882,
                77.543543
            ]],
        "key": "Auth Key"} 
headers = {'Content-Type': 'application/json'}
r = requests.post(url = "https://data.geoiq.io/dataapis/v1.0/covid/locationcheck", data = js.dumps(body), headers = headers)
