如何在dart中使用request.send()获取响应体

dependencies:
  http: ^0.13.3

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

void main() async {
  try {
    final response = await http.get(Uri.parse('https://api.example.com/data'));
    if (response.statusCode == 200) {
      print('Response body: ${response.body}');
    } else {
      print('Failed to load data');
    }
  } catch (e) {
    print('Error: $e');
  }
}

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

void main() async {
  try {
    final response = await http.post(
      Uri.parse('https://api.example.com/data'),
      body: jsonEncode({'key': 'value'}),
      headers: {'Content-Type': 'application/json'},
    );
    if (response.statusCode == 200) {
      print('Response body: ${response.body}');
    } else {
      print('Failed to post data');
    }
  } catch (e) {
    print('Error: $e');
  }
}
