titans

Selenium automation framework - Selenium自动化框架

前端

采用Element-UI进行前端布局设计，前后分离的模式

更新新版 vue 2.6.11 版本，之前旧版要使用 build 目录，导致旧版有问题

生成生产环境

npm run build

nginx 配置

server {
        listen       80;
        server_name  www.titans.com ;
        root   "F:/Python/titans/admin/frontend/dist";
        location /$ {
            index  index.html index.htm;
            try_files $uri $uri/;
        }
}

配置好后，就能够使用前端页面了

注意这里面要将frontend->config->index.js->build下的assetsPublicPath: '/' 改为assetsPublicPath: './' 才能找到静态文件 的路径

后端

flask 框架进行编写，数据表结构如下

CREATE TABLE `configs` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `type` varchar(32) NOT NULL COMMENT '任务类型',
  `name` varchar(32) DEFAULT NULL COMMENT '任务名称',
  `json_text` json DEFAULT NULL COMMENT '任务命令集',
  PRIMARY KEY (`id`),
  UNIQUE KEY `type` (`type`,`name`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;


CREATE TABLE `tasks` (
  `id` int(11) NOT NULL,
  `uuid` varchar(36) NOT NULL COMMENT '分布式唯一id',
  `result` json DEFAULT NULL COMMENT '结果集',
  `type` varchar(32) DEFAULT NULL COMMENT '任务类型',
  `name` varchar(32) DEFAULT NULL COMMENT '任务名',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

nginx 反向代理配置

server {
        listen       80;
        server_name  www.titans.com ;
        root   "F:/Python/titans/admin/frontend/dist";
        location /$ {
			index  index.html index.htm;
            try_files $uri $uri/;
        }
		location /api/configs/ {
			proxy_set_header Host $host;
			proxy_set_header X-Forwarded-For $remote_addr; 
            proxy_pass   http://127.0.0.1:5000/configs/;
        }
}

执行命令

进入到 titans -> admin 目录下，执行以下命令启动 web 服务

python app.py

服务端

Selenium 自动化框架，采用 json 配置化的形式进行数据采集或自动化测试等

架构

配置使用

配置中使用{}作为一个组件的调用，[]作为一个作用域来使用。 {}有三个基本参数：

  1. args配置参数

  2. type组件使用具体方法

  3. component所使用的组件名称

[]主要是作用域，用于if, for, while循环这些有自己作用域的组件，然后在里面调用{}就可以 实现流程控制了

boss直聘数据拉取栗子：

优势

采用json配置化的方式进行浏览器自动化，现在已有10+组件强力驱动，可以应对绝大多数的自动化操作。这个 框架最大特点就是编写json就可以实现像写代码一样进行流程控制，为采集网站结构变动提供无需重启服务的 便利
