如何使用筆記本服務器 rest api 或 python 代碼創建新的 jupyter 筆記本單元並更新單元？

Question

我是 python 編碼的新手。我能夠使用 jupyter 筆記本服務器 rest api 創建 new.ipynb 文件。

我正在使用以下 curl 命令使用 rest api 創建一個 new.ipynb 文件，

curl -X PUT "http://localhost:8890/api/contents/two.ipynb" -H "accept: application/json" -H "Authorization: Token xxxxxxxx" -d "{\"name\": \"one.ipynb\"}"

現在，我正在嘗試使用 jupyter notebook 服務器 rest api 或使用 python 代碼創建一個新的 jupyter notebook 單元，並使用基本打印語句更新單元。 但拿不到。 有誰知道如何解決這個問題？

提前致謝！

Answer 1

我使用以下代碼完成了任務：創建新筆記本：

import requests
import nbformat as nbf
import sys
from nbconvert.preprocessors import ExecutePreprocessor
import json
import os

def create_nb():
api_url =  'http://192.168.1.xxx:8890/api/contents/root/ppl'
headers = {'token': 'token_passwd'}
headers1 = {'Authorization': 'Token token_passwd'}
body={"type": "notebook"}

result = requests.post(api_url,headers=headers1,json=body)
output=result.json()

return('/'+output["path"])

在指定路徑中創建一個新單元格：

def create_cell(path,session_id):

head,file_name = os.path.split(path)
file_path=path[1:]

api_url =  'http://192.168.1.126:8890/api/sessions/'+session_id
headers1 = {'Authorization': 'Token token_passwd','Content-Type': 'application/json'}
body={"name":file_name, "type": "notebook","path": file_path,"kernel": {"name": "python3"}}
#result = requests.post(api_url,headers=headers1,json=body)

present_id=requests.get(api_url,headers=headers1)
#print("present_id ---->>> "+present_id.json()["id"])
nb1 = nbf.read(path, as_version=4)
code=""""""
nb1['cells']= nb1['cells']+[nbf.v4.new_code_cell(code)]
with open(path, "w") as f:
    nbf.write(nb1, f)

return("cell created")
