【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> JVM总结慢慢来吧，先插播一篇水文，来介绍下最近业余一直在写的一个小项目——easy-httpserver（ github ）。适合新手学习，大神们路过即可^_^。 一、这是个什么玩意？ easy-httpserver本来的目的是实现一个简易的java web服务器 ，基于jdk自带的httpserver实现，可以处理http请求，使用方式类似于jetty，以jar包方式嵌入项目 。但是准确的说他又不单算一个web服务器， easy-httpserver集成了MVC中部分View和Controller的功能，使web项目只用按照规则实现页面、controller以及对应的业务处理，就能直接部署运行。 所以说，这是个什么玩意我也说不清，但是我的目的就是打造一款能够快速开发部署小型web项目的框架（虽然现在离这个目的还有一些差距）。 二、为什么要写这么个东西？ 理由有如下几点： 摘要里提到的原因。 之前一直想弄明白web服务器的运行原理，虽然看了一些资料，但是还是一知半解，正好自己写个简单的来体会体会。 年后想搭建一个个人博客，希望能够自己定制一些功能，但是搜了下发现java的开源博客要么不好用，要么不好改，还不如自己写一个（域名、空间都买了，真有点裤子都脱了，结果.....的感觉）。所以就打算自己慢慢搞个小框架

node httpServer EADDRINUSE and next port

由 感情迁移 提交于 2019-12-24 07:05:41
问题 I try to increment a port number based on 8000 if the port is busy with EADDRINUSE , and I thought it's as easy as the below: var tryToOpenServer = function(port) { console.log('trying to Open: ' + port); HTTPserver .listen(port, function() { console.log('HTTP listening:' + port); }) .on('error', function(err) { if (err.code === 'EADDRINUSE') { // port is currently in use console.log('server Open error:' + port); tryToOpenServer(port + 1); } }); }; tryToOpenServer(8000); If the port:8000 is

HttpURLConnection - Lots of requests

问题 I have written a service which is used to register some data. That service can be called thousands of times. The parameters are passed via the URL itself. The client part of it looks something like this: private String getNodeInfoFromGPSForSpecificSubscriber( int subscriberId ) throws Exception { String requestURLToNode = "http://" + GPSConstants.GPS_IP + ":" + GPSConstants.PORT_NUMBER + APIs.FetchASpeecificNodeAPI.FETCH_A_SPECIFIC_NODE + "?" + APIs.FetchASpeecificNodeAPI.SUBSCRIBER_ID + "="

How to serve any file type with Python's BaseHTTPRequestHandler

由 喜夏-厌秋 提交于 2019-12-21 03:52:26
问题 Consider the following example: import string,cgi,time from os import curdir, sep from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer class MyHandler(BaseHTTPRequestHandler): def do_GET(self): try: if self.path.endswith(".html"): f = open(curdir + sep + self.path) #self.path has /test.html #note that this potentially makes every file on your computer readable by the internet self.send_response(200) self.send_header('Content-type', 'text/html') self.end_headers() self.wfile.write(f

How do I map incoming “path” requests when using HTTPServer?

由 眉间皱痕 提交于 2019-12-20 20:23:46
问题 I'm fairly new to coding in python. I created a local web server that says "Hello World" and displays the current time. Is there a way to create a path, without creating a file, on the server program so that when I type in "/time" after 127.0.0.1 in the browser bar, it will display the current time? Likewise if I type "/date" it will give me the current date. This is what I have so far: from BaseHTTPServer import BaseHTTPRequestHandler,HTTPServer import datetime port = 80 class myHandler

Are there languages/software that implements http status code 418?

由 纵然是瞬间 提交于 2019-12-20 16:24:20
问题 I know that status code 418 was defined as a April Fools' joke, and "is not expected to be implemented by actual HTTP servers" as is stated on Wikipedia. But I would be interested if any of you knew of a language/webserver/IDE that supports it. I was trying on Apache (via php), and obviously it got me an internal error (500). I just like the humor behind it (am not trying to troll here) and would like to know if more than just Emacs implements this. More precisely: It could be emulated in php

How to limit the connections count of an HTTP Server implemented in Go?

问题 I am trying to implement an HTTP Server in Golang. My problem is, I have to limit the maximum active connections count at any particular time to 20. 回答1: You can use the netutil.LimitListener function to wrap around net.Listener if you don't want to implement your own wrapper:- connectionCount := 20 l, err := net.Listen("tcp", ":8000") if err != nil { log.Fatalf("Listen: %v", err) } defer l.Close() l = netutil.LimitListener(l, connectionCount) log.Fatal(http.Serve(l, nil)) 回答2: The trick with

How can I receive an uploaded file using a Golang net/http server?

问题 I'm playing around with Mux and net/http . Lately, I'm trying to get a simple server with one endpoint to accept a file upload. Here's the code I've got so far: server.go package main import ( "fmt" "github.com/gorilla/mux" "log" "net/http" ) func main() { router := mux.NewRouter() router. Path("/upload"). Methods("POST"). HandlerFunc(UploadCsv) fmt.Println("Starting") log.Fatal(http.ListenAndServe(":8080", router)) } endpoint.go package main import ( "fmt" "net/http" ) func UploadFile(w http

How to display HTTP 401 basic authentication dialog

问题 I am new to web development. I have Android application that hosts some web pages using HTTPServer. I am using Netty to decode/encode request/responses. Now, I want to display basic authentication dialog when someone navigates to the my webpage. Something like this: Can I get some pointers ? Is it something HTTP built in functionality, any RFC ? Do I need to write some java script ? Any help would be great. 回答1: You just need to send the appropriate headers when a client requests a resource
