如何在Flutter中将cURL转换为http post

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

void main() async {
  // 目标URL
  String url = 'https://example.com/api/submit';

  // 请求体数据
  Map<String, String> data = {
    'key1': 'value1',
    'key2': 'value2',
  };

  // 发送HTTP POST请求
  var response = await http.post(Uri.parse(url), body: data);

  // 检查响应状态码
  if (response.statusCode == 200) {
    print('请求成功');
    print('响应内容: ${response.body}');
  } else {
    print('请求失败: ${response.statusCode}');
  }
}

var response = await http.post(Uri.parse(url), body: data, timeout: Duration(seconds: 10));

import 'dart:convert';

var jsonResponse = jsonDecode(response.body);
print(jsonResponse['key']);

try {
  var response = await http.post(Uri.parse(url), body: data);
  if (response.statusCode == 200) {
    print('请求成功');
  } else {
    print('请求失败: ${response.statusCode}');
  }
} catch (e) {
  print('请求异常: $e');
}
