如何使用Python寫一個Docker遠程管理工具_API數據的json格式化輸出

一、前言

最近想自己手動寫一個基於DockerAPI的遠程管理工具，本系列文章將一直記錄編寫過程中遇到的問題及解決方法

二、面臨的問題

2.1、API數據混亂

一開始我寫的代碼是這樣的

import json
import requests
url = 'http://1.1.1.11:2375/containers/json?all=1'
r = requests.get(url)
decoded = json.dumps(r.text)
print(decoded)

執行結果是這樣的

而我希望得到的數據是這樣的

root@ubuntu20:~# curl http://1.1.1.11:2375/containers/json  | python3 -m json.tool
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  1194  100  1194    0     0  1166k      0 --:--:-- --:--:-- --:--:-- 1166k

                    "DriverOpts": null
                }
            }
        },
        "Mounts": []
    }
]

三、解決方法

其實只需要把text改成json即可

import json
import requests
url = 'http://1.1.1.11:2375/containers/json?all=1'
r = requests.get(url)
decoded = json.dumps(r.json(), indent=4)
print(decoded)

然後得到的結果是這樣的
