whistle.middleware

安装

npm install whistle.middleware --registry=https://registry.npmmirror.com

使用

# 规则
pattern middleware://D:\temporary\test.js

pattern middleware://test.js # 这里需要在插件选项里设置根目录为
pattern middleware://test.js?p1=v1&p2=v2 # 可以通过 ? 传递参数，使用 ctx.utils.params 读取

文件 test.js:

/**
 * 请求拦截
 * 
 * 如果 onRequest 返回 `false` 表示不再把请求透传给源服务，这个时候可以使用 `ctx.writeHead`/`ctx.end` 异步输出想要的响应内容

 *      requestBody: unknown, 
 *      json: (data: unknown) => void, // 调用该函数可以直接返回指定内容，不再执行后续请求
