Flutter网络请求调试插件dio_request_inspector的使用

Dio Requests Inspector 是一个用于 Dio 的 HTTP 请求和响应拦截与日志记录工具。它可以帮助开发者更好地调试网络请求，提高开发效率。

特性

• ✅ 拦截并记录 HTTP 请求和响应
• ✅ 使用密码保护 HTTP 请求的安全性
• ✅ 根据请求时间、方法和状态过滤日志
• ✅ 通过路径搜索日志
• ✅ 轻松分享请求和响应数据
• ✅ 美化 JSON 数据
• ✅ 界面美观

如何使用

1. 添加依赖

在 pubspec.yaml 文件中添加 dio_request_inspector 包：

flutter pub add dio_request_inspector

2. 配置 MaterialApp

在 MaterialApp 中添加 navigatorObservers：

import 'package:dio_request_inspector/dio_request_inspector.dart';

void main() {
  runApp(DioRequestInspectorMain(
    isDebugMode: true,
    child: MyApp(),
  ));
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Dio Request Inspector',
      navigatorObservers: [
        DioRequestInspector.navigatorObserver,
      ],
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(),
    );
  }
}

3. 设置 Dio 实例

在你的 Dio 实例中添加拦截器：

import 'package:dio/dio.dart';
import 'package:dio_request_inspector/dio_request_inspector.dart';

final DioRequestInspector inspector = DioRequestInspector(
  isDebugMode: true,
  duration: const Duration(milliseconds: 500),
  showFloating: true,
  password: '123456', // 可选，设置密码保护
);

final Dio _dio = Dio();
_dio.interceptors.add(inspector.getDioRequestInterceptor());

4. 示例 Demo

以下是一个完整的示例代码，展示了如何使用 dio_request_inspector 插件进行网络请求调试：

import 'package:dio/dio.dart';
import 'package:dio_request_inspector/dio_request_inspector.dart';
import 'package:flutter/material.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(DioRequestInspectorMain(
    isDebugMode: true,
    child: const MyApp(),
  ));
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Dio Request Inspector',
      navigatorObservers: [
        DioRequestInspector.navigatorObserver,
      ],
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  late Dio _dio;
  final DioRequestInspector inspector = DioRequestInspector(
    isDebugMode: true,
    duration: const Duration(milliseconds: 500),
    showFloating: true,
    password: '123456',
  );

  [@override](/user/override)
  void initState() {
    _dio = Dio();
    _dio.interceptors.add(inspector.getDioRequestInterceptor());
    super.initState();
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Dio Request Inspector Example'),
        backgroundColor: Colors.purple.withOpacity(0.6),
      ),
      body: Container(
