Dart使用http_server做简易数据测试服务 ​

初始化目录 ​

1. 增加main.dart,服务配置,接口处理
2. 增加data.dart,返回前端的数据
3. 增加pubspec.yaml,项目配置
   dart

   name: dart_server
   description: Dart数据测试服务
   dependencies:
       http_server: ^0.9.6

   name: dart_server
   description: Dart数据测试服务
   dependencies:
       http_server: ^0.9.6

4. 如使用VSCode,注意program内容需指向main.dart
   json

       // 悬停以查看现有属性的描述。
       // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387
       "version": "0.2.0",
       "configurations": [
           {
               "name": "Dart",
               "program": "main.dart",
               "request": "launch",
               "type": "dart"
           }
       ]
   }

   {
       // 使用 IntelliSense 了解相关属性。 
       // 悬停以查看现有属性的描述。
       // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387
       "version": "0.2.0",
       "configurations": [
           {
               "name": "Dart",
               "program": "main.dart",
               "request": "launch",
               "type": "dart"
           }
       ]
   }

5. 安装依赖pub get

配置 ​

1. data.dart中通过定义不通数据返回的变量即可

2. main.dart

   dart

   import 'dart:convert';
   import 'dart:io';
   import 'data.dart';
   
   main() async {
       //配置IP和端口
       var requestServer = await HttpServer.bind('192.168.199.163', 9090);
       print('服务启动成功');
       //处理请求
       await for(HttpRequest request in requestServer){
           handleMessage(request);
       }
   }
   
   //处理请求
   void handleMessage(HttpRequest request){
       try{
           if(request.method == "GET"){
           handleGET(request);
           }else if(request.method == "POST"){
           handlePOST(request);
           }
       }catch(e){
           print('服务器发生异常: $e');
       }
   }
   
   //处理GET请求
   void handleGET(HttpRequest request){
       //获取请求参数
       var action = request.uri.queryParameters['action'];
       //判断action区分接口
       if(action == 'getProducts'){
           //接收Get参数
           var page = request.uri.queryParameters['page'];
           print('获取产品数据...$page');
           request.response
           ..statusCode=HttpStatus.ok
           ..write(json.encode(products)) //返回数据到前端
           ..close();
       }
   }
   
   //处理POST请求
   void handlePOST(HttpRequest request){
       //TODO
   }

   import 'dart:convert';
   import 'dart:io';
   import 'data.dart';
   
   main() async {
       //配置IP和端口
       var requestServer = await HttpServer.bind('192.168.199.163', 9090);
       print('服务启动成功');
       //处理请求
       await for(HttpRequest request in requestServer){
           handleMessage(request);
       }
   }
   
   //处理请求
   void handleMessage(HttpRequest request){
       try{
           if(request.method == "GET"){
           handleGET(request);
           }else if(request.method == "POST"){
           handlePOST(request);
           }
       }catch(e){
           print('服务器发生异常: $e');
       }
   }
   
   //处理GET请求
   void handleGET(HttpRequest request){
       //获取请求参数
       var action = request.uri.queryParameters['action'];
       //判断action区分接口
       if(action == 'getProducts'){
           //接收Get参数
           var page = request.uri.queryParameters['page'];
           print('获取产品数据...$page');
           request.response
           ..statusCode=HttpStatus.ok
           ..write(json.encode(products)) //返回数据到前端
           ..close();
       }
   }
   
   //处理POST请求
   void handlePOST(HttpRequest request){
       //TODO
   }
