使用http flutter的Post阵列

dependencies:
  http: ^0.13.3

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

void postData() async {
  var url = Uri.parse('https://example.com/api');
  var headers = {'Content-Type': 'application/json'};
  var data = [
    {'name': 'John', 'age': 25},
    {'name': 'Jane', 'age': 30},
    {'name': 'Bob', 'age': 35}
  ];
  var body = jsonEncode(data);

  var response = await http.post(url, headers: headers, body: body);

  if (response.statusCode == 200) {
    // 请求成功
    print('请求成功');
    print(response.body);
  } else {
    // 请求失败
    print('请求失败');
    print(response.statusCode);
  }
}
