java18學習筆記-Simple Web Server

408:Simple Web Server

Python、Ruby、PHP、Erlang 和許多其他平臺提供從命令行運行的開箱即用服務器。這種現有的替代方案表明了對此類工具的公認需求。

提供一個命令行工具來啟動僅提供靜態文件的最小web服務器。沒有CGI或類似servlet的功能可用。該工具將用于原型設計、即席編碼和測試目的，特別是在教育背景下。

Simple Web Server是一個用于服務單個目錄層次結構的最小HTTP服務器。它基于自2006年以來JDK中包含的com.sun.net.httpserver包中的web服務器實現。該包得到了官方支持，我們用API對其進行了擴展，以簡化服務器創建并增強請求處理。Simple Web Server可以通過專用命令行工具jwebserver使用，也可以通過其API以編程方式使用。

以下命令啟動簡單Web服務器

通過jwebserver運行

jwebserver

然后在提示serving的目錄下放一張圖片asd.jpg，然后請求結果如下

注意僅支持 HTTP/1.1。不支持 HTTPS。（但是測試了幾次HTTP/2.0是可以訪問到的）

命令的幾個參數也很簡單

Options:-h or -? or --helpPrints the help message and exits.-b addr or --bind-address addrSpecifies the address to bind to.  Default: 127.0.0.1 or ::1 (loopback).  Forall interfaces use -b 0.0.0.0 or -b ::.-d dir or --directory dirSpecifies the directory to serve.  Default: current directory.-o level or --output levelSpecifies the output format.  none | info | verbose.  Default: info.-p port or --port portSpecifies the port to listen on.  Default: 8000.-version or --versionPrints the version information and exits.To stop the server, press Ctrl + C.

通過JSHELL運行

在Jshell中導入會報錯?sun.net.httpserver.simpleserver.FileServerHandler

import sun.net.httpserver.simpleserver.FileServerHandler;
| ?錯誤:
| ?程序包 sun.net.httpserver.simpleserver 不可見
| ? ?(程序包 sun.net.httpserver.simpleserver 已在模塊 jdk.httpserver 中聲明, 但該模塊未導出它)
| ?import sun.net.httpserver.simpleserver.FileServerHandler;
| ? ? ? ? ^-----------------------------^

所以可以自己復制一個一模一樣的FileServerHandler?

同樣的sun.net.httpserver.simpleserver.ResourceBundleHelper也復制一個

ResourceBundleHelper

import java.text.MessageFormat;
import java.util.Locale;
import java.util.MissingResourceException;
import java.util.ResourceBundle;class ResourceBundleHelper {static final ResourceBundle bundle;static {try {bundle = ResourceBundle.getBundle("sun.net.httpserver.simpleserver.resources.simpleserver");} catch (MissingResourceException e) {throw new InternalError("Cannot find simpleserver resource bundle for locale " + Locale.getDefault());}}static String getMessage(String key, Object... args) {try {return MessageFormat.format(bundle.getString(key), args);} catch (MissingResourceException e) {throw new InternalError("Missing message: " + key);}}
}

復制到Jshell執行

復制到Jshell執行

創建簡單的服務

import com.sun.net.httpserver.HttpServer;
import java.io.IOException;
import java.net.InetSocketAddress;
import java.nio.file.Path;
import java.util.function.UnaryOperator;UnaryOperator<String> identity = UnaryOperator.identity();var server = HttpServer.create(new InetSocketAddress(9000), 10, "/img/",FileServerHandler.create(Path.of("D:\\Program Files"), identity));server.start();

由于在idea中執行放在jshell中執行之后報端口被占用異常，關了idea中的就好了

另外jshell中運行的需要手動自己去找服務停止。

參數解釋

9000? 端口號

10 最大并發數量? <1的話默認會設置成50

/img/? 訪問鏈接前綴

D:\\Program Files 代理到的目標文件，此文件夾下的文件都可以通過http://127.0.0.1:+端口9000+訪問前綴/img/?+文件夾下的文件名（帶后綴）如下

http://127.0.0.1:9000/img/asd.jpg
