1、通过get方式请求获取参数的方式有两种
通过上下文获取
通过request获取
获得的格式有两种:query与querystring
注意:querystring为小写,驼峰格式会导致无法获取
2、示例
const Koa = require('koa'); const app = new Koa(); app.use(async(ctx) => { let url = ctx.url; let request = ctx.request; let req_query = request.query; let req_queryString = request.querystring; let ctx_query = ctx.query; let ctx_queryString = ctx.querystring; ctx.body = { url, req_query, req_queryString, ctx_query, ctx_queryString } }) app.listen(3000) console.log("demo is starting at port 3000")
