在flutter中使用dio来获得源和目的地之间的距离

dependencies:
  dio: ^3.0.10

import 'package:dio/dio.dart';

Dio dio = Dio();

String origin = "源地址";
String destination = "目的地地址";
String apiKey = "你的高德地图API密钥";

try {
  Response response = await dio.get(
    "https://restapi.amap.com/v3/distance",
    queryParameters: {
      "key": apiKey,
      "origins": origin,
      "destination": destination,
    },
  );

  if (response.statusCode == 200) {
    // 解析响应数据
    var data = response.data;
    // 处理数据并获取距离信息
    var distance = data["results"][0]["distance"];
    print("源和目的地之间的距离为：$distance 米");
  } else {
    print("请求失败");
  }
} catch (e) {
  print("发生异常：$e");
}
