关于快速路由器部分,我建议在超模式中使用您的 uri 模板(阅读更多)...
然后,您还可以从 express.js 支持的路由器的正则表达式中受益。关于解析参数,您需要一个 RFC 6570 实现,例如https://github.com/geraintluff/uri-templates ...
下面是一些 .js 代码,用于说明使用 RFC 6570 重写超模式
以将其转换为快速 js 路由器:
var hyperschema = {
"$schema": "http://json-schema.org/draft-04/hyper-schema",
"links": [
{
"href": "{/id}{/ooo*}{#q}",
"method": "GET",

"schema": {
"type": "object",
"properties": {
"params": {
"type": "object",
"properties": {
"id": {"$ref": "#/definitions/id"}
},
"additionalProperties": false
}
},
"additionalProperties": true
}
}
],
"definitions": {
"id": {
"type": "string",
"pattern": "[a-z]{0,3}"
}
}
}
