SpaceX的代碼開源了，來看看火箭技術的代碼.Spacex Rest API設計很有參考價值

SpaceX

世界上可以擁有載人航天技術是美俄中馬。其中只有馬斯克的SpaceX屬於民營商用企業。

SpaceX API Docs

https://docs.spacexdata.com/?version=latest

這裏有完整的postman請求測試用例。api的說明文檔。

各種編程語言的客戶端

支持Python，Go，Rust,Ruby 等主流的客戶端。但並沒有給出Java …難不成Java 已經脫離了主流…
https://github.com/r-spacex/SpaceX-API/blob/master/docs/clients.md

Apps / UI clients

支持主流的web,ios,Android

總結

文檔非常的詳細，可以作爲我們設計Rest APi 的參考。包括文檔，接口的設計情況。對我們的開發還是有很大的幫助。
見證過優秀的代碼，可以讓自己變得更加優秀。

像SpaceX一樣，一飛沖天。
