millisecのgetリクエストをキャッシュさせない。

Posted at

urlのパラメータ末尾にランダムな値を入れる。

//ex) superagent
return req.get(url).set(...)
   .query({_:Date.now() +''+performance.now().toString().replace('.','') }) //no-chash
   .then(res=>res.body)

秒単位でも問題ない場合

.query({_:Date.now()})

Date系がない場合

.query({_:Math.floor(Math.random()*10000000000000)})

更新したデータによってcacheの切り替えをする場合。

//hashが被ればcacheデータを使ってくれる。ブラウザなどに依存。
.query({_:md5(newdata)})
