看了30 天精通 RxJS 系列 想提問
hi JerryHong,
看了你鐵人賽中寫的關於RxJS系列文章，受益頗多。
正在練習寫一個爬蟲，碰到些問題可以向你請教嗎？
目前的結構是這樣的
Observable.from(<array of urls>)
.mergeMap(url => <promise of requests>, <concurrency>)
.map(res => <data object needed>)
.concatAll()
.withLatestFrom(<db>, (x, y) => <query promise>)
.concatAll()
.catch(e => <retry error>) // 不知道這裡怎麼寫
.subscribe()
在運行中偶爾會出現錯誤 但是 catch retry retryWhen 似乎都是要重新從頭運行
能不能只 retry 出錯的那個 request 呢
iT邦幫忙註冊了還是不能發簡訊
就通過搜索來了這裡
