嗨嗨嗨，又到了写轮子环节了，为什么要写这个东西呢？
这次带来的还是一个库，我们之前测试接口会使用一些工具，postMan，apiFox 等。
这些库需要安装，我想着搞一个命令行交互式的，可以快捷测试接口，类似于curl那种，只不过我的工具更加傻瓜式。
文档地址 www.npmjs.com/package/xmw…
安装
npm i xmwc -g
安装完成之后会有一个命令叫wc
wc -h
可以查看帮助
Usage: wc [options] [command] 请求API Options: -V, --version output the version number -h, --help display help for command Commands: get 快捷发起get请求 post 快捷发起post请求 ws socket套接字测试
使用方法
直接调用wc命令
wc
1.wc
选择是否从缓存读取Y读取N取消 如果没有使用过建议N
2.选择请求方式 GET POST 等.....
3.选择请求头 application/x-www-form-urlencoded application/json 等
4.输入请求资源路径 也就是url
5.输入参数如果是get可以忽略
6.选择返回格式(默认json) text blob buffer
7.是否缓存 Y 缓存 N 取消 缓存起来可以下次直接使用
成功返回success
失败error
采用选项式操作，如果添加到缓存里面可以下次直接发起请求
2.快捷发起请求
如果不想繁琐的去选择也可以使用快捷发送请求
wc get 命令
wc post
wc ws
支持测试webSocket
