nginx是什么?它有什么作用?
NGINX是一个集静态资源、负载均衡于一身的修改Web服务器，主要支持HTTP/1、源码HTTP/2、修改MAIL邮件、源码TCP协议、修改跑腿小弟源码UDP协议等。源码
在Web场景中，修改NGINX提供HTTP协议的源码支持，同时也能够通过其强大的修改文件读取能力，提供、源码JavaScript、修改CSS、源码HTML等资源的修改下载能力。NGINX通过零拷贝技术、源码Linux的原生异步IO和直接IO以及Nagle、Cork等算法，优化了文件发送和小报文的发送，使得性能显著提升，300行源码相较于其他Web服务器如Tomcat、Netty、Apache等有明显优势。主流CDN服务都采用NGINX来实现。
NGINX的负载均衡功能强大，能够高效处理应用层协议，适用于分布式系统中的应用扩展。其支持多路复用、事件驱动技术，可轻松支持CM级别的并发，与操作系统紧密结合的架构使其能够充分利用CPU、内存等硬件资源，提供高效率的负载均衡服务。NGINX的架构灵活，允许第三方以C模块形式与官方模块协作，支持多种应用层协议，用户可自行开发C模块定制NGINX功能。NGINX使用开放的androidble助手源码2-clause BSD-like license源码许可协议，用户在修改源码后，可以作为商业用途发布，如TEngine、Openresty和Kong等。
总之，NGINX具备提供Web服务、处理静态资源和实现负载均衡的能力，尤其在处理文件发送和小报文发送方面表现出色，并支持多种协议和应用层处理，提供灵活的架构和开放的许可协议，使其在Web服务器领域具有显著优势。
通俗易懂的api网关 kong 教程入门
API-Gateway的引入是为了简化客户端的管理，提供接口重构的灵活性，并实现统一权限控制和日志统计，同时扮演着保护内部服务的安全屏障。Mashape开源的Kong以其基于Nginx的高性能和高可用性脱颖而出。Kong的核心在于其插件机制，通过Lua编写扩展功能，商城源码抽奖如HTTP认证、CORS、流量控制、日志记录等，已支持大量基础操作。Kong的架构由Server（基于Nginx），数据存储（Cassandra或PostgreSQL）以及dashboard管理工具组成，支持横向扩展和负载均衡。
Kong的特性包括可扩展性，通过添加服务器轻松应对高流量，模块化设计使其能通过插件扩展功能，适用于各种环境部署。插件系统使得Kong能够提供身份认证、安全控制、流量管理、分析监控等功能。一个典型的请求流程是：Kong接收并代理API请求，同时执行预先配置的app源码陷阱插件，然后将请求转发到目标API。
学习Kong，可以从配置服务、添加路由，到启用认证插件和消费者管理，以及利用其RESTful管理API进行精细操控。Kong还提供了丰富的插件选项，如Key-Auth、CORS、限流和日志处理。通过监控和配置API，Kong成为高效、安全的API管理平台。要深入学习，可以参考相关视频教程，如分布式API网关Kong的原理与实践、Nginx源码实现等内容。
word中如何使用代码高亮插件
使用代码高亮插件的步骤如下：
步骤一：下载插件和源代码：SyntaxHighlighter4Word.zip
步骤二：下载文件后，解压，然后双击bin\word\Kong.SyntaxHighlighter.Word.vsto或bin\word\Kong.SyntaxHighlighter.Word.vsto，即可完成安装，当然前提是你装了.net framework 4.0。安装成功后的提示如下：
步骤三：安装插件后，会在word中多一个功能区(支持word和word)：
步骤四：点击"设置"按钮，弹出设置界面：
步骤五：这里简化了配置，去掉了前一个版本中的一些设置。
步骤六：点击"插入代码"按钮，弹出如下界面：
步骤七：可以选择C#、Java、Xml、Javascript等多种语言。
步骤八：在word效果如下：
步骤九：发布到博客后的效果如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Kong.SyntaxHighlighter.Winform;
using Microsoft.Office.Tools.Ribbon;
namespace Kong.SyntaxHighlighter.Word
{
public partial class Ribbon1
{
private void Ribbon1_Load(object sender, RibbonUIEventArgs e)
{
}
}
}
步骤十：我在Word中生成这段代码的时候，用了ol和li，并且设置了ol以及li的style，这样在word中就可以显示边框以及交替行的颜色，同时给ol设了一个class=codeBlock，妄想在发布到博客后可以通过这个样式名codeBlock来自定义自己喜欢的样式。我在word中生成的代码大概是这个样子：
步骤十一：所以我们在博客中，不得设置所有ol的style，幸好博客园的文章都是在一个id为cnblogs_post_body的div下的，所以我在我博客中加了下面的style：
#cnblogs_post_body ol
{
border: 1px dotted #;
line-height: %;
word-break: break-word;
font-family: Consolas, Verdana !important;
border-radius: 5px;
width: %;
background-color: #E3E3FF;
list-style-position: outside;
margin-left: 0px;
}
#cnblogs_post_body ol font
{
font-size: px !important;
}
#cnblogs_post_body ol li
{
background-color: #fff;
padding-left: 5px;
border-left: 1px solid #8A8AFF;
margin-left: 5px !important;
}
#cnblogs_post_body ol li:nth-child(even)
{
background-color: #9ac4e5;
}
步骤十二：补充一下，这段文本是加在这里的：

kong 网关插件快速开发指南
通过使用kong网关插件，开发流程变得简单明了且高效。kong插件项目主要包含三个文件：handler.lua负责处理插件逻辑，schema.lua定义配置文件，而rockspec文件用于插件安装。逻辑处理代码根据openresty的不同处理阶段分为不同函数，根据插件功能只需在相应函数内添加自定义业务逻辑。
以开发一个简单的灰度发布流量分发插件为例，其功能仅是根据http request头中的Authorization值，将流量分发至不同后端服务器。该插件配置包含两个选项：pattern和upstream。如果Authorization值匹配pattern，请求将代理至相应upstream。
首先，为插件命名为“huidu”，修改模版项目目录为“huidu”。接着，修改schema.lua添加配置代码，然后在handler.lua中添加处理逻辑。由于huidu插件逻辑只需在access阶段执行，可以移除多余注释和代码。至此，代码开发阶段完成。
进行插件安装调试。假设已搭建本地开发环境，手动指定目录安装插件。修改kong.conf文件配置插件，保存后启动kong。在启动日志中确认加载了插件。通过konga界面配置插件，创建服务并安装插件。配置后，数据将保存在kong后端数据库的plugins表中。进行测试以验证插件效果。
在测试阶段，若请求匹配插件配置，响应应符合预期；若不匹配或代码有误，则流量将走服务本身配置的upstream。配置后的数据保存在数据库中。
在正式环境部署时，通过luarocks安装插件。编辑rockspec文件修改配置，注意查看本地和linux安装路径差异。安装完成后，运行kong restart生效。开发完成后，建议参考官方插件开发文档和kong自带插件库源代码，优化插件功能。
基于此流程，简单功能的插件开发效率较高，可实现一天一个。开发时，应避免功能逻辑过于复杂，保持简单实用。示例插件代码和官方开发文档可参考指定链接。
