如何使用 Flutter [1]： https://i.stack.imgur.com/V6hVH.png格式從 API 獲取數據

Answer 1

基本上，您的 API 端點正在請求正文。
在 flutter 中，可以使用 package 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 端點需要身份驗證令牌。 例如 Bearer token 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',
});

請在下面找到示例請求。

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)
