解析nginx配置文件 nginx-java-parser

Nginx configuration Java parser

解析nginx配置文件,并将nginx配置文件格式化成对象,方便java程序管理nginx配置。解析配置文件并非使用正则匹配,而是使用语法分析树处理解决的。
This library helps in analyzing Nginx web server configuration files, looking up for specified parameters, blocks, regular expressions or comments. Then AST can be modified and converted back to plain file.

Features

  • Convert config file to AST tree using ANTLR4 parsing capabilities
  • The same is available for JavaCC too (deprecated)
  • Rebuild config files and dump them back to *.conf
  • Nested blocks support
  • If statements support
  • Unquoted regexp within location/rewrite/if statements support
  • Comments support

Installation

Add the following dependency to your POM:

<dependency>      <groupId>com.github.odiszapc</groupId>      <artifactId>nginxparser</artifactId>      <version>0.9.3</version>  </dependency>

Examples

Parser

How to perform basic parsing of the following Nginx config:

NgxConfig conf = NgxConfig.read("/etc/nginx/nginx.conf");  NgxParam workers = conf.findParam("worker_processes");       // Ex.1  workers.getValue(); // "1"  NgxParam listen = conf.findParam("http", "server", "listen"); // Ex.2  listen.getValue(); // "8889"  List<NgxEntry> rtmpServers = conf.findAll(NgxConfig.BLOCK, "rtmp", "server"); // Ex.3  for (NgxEntry entry : rtmpServers) {      ((NgxBlock)entry).getName(); // "server"      ((NgxBlock)entry).findParam("application", "live"); // "on" for the first iter, "off" for the second one  }

/etc/nginx/nginx.conf:

worker_processes  1;            # <- Ex.1    http {      server {          listen       8889;      # <- Ex.2          server_name  localhost;      }  }    rtmp {      server {                    # <- Ex.3 (first)          listen 1935;          application myapp {              live on;          }      }        server {                    # <- Ex.3 (second)          listen 1936;          application myapp2 {              live off;          }      }  }
Dumper
NgxConfig conf = NgxConfig.read("/etc/nginx/nginx.conf");  // ...  NgxDumper dumper = new NgxDumper(conf);  return dumper.dump(System.out);
