python 讀取單所有json數據寫入mongodb(單個)

<--------------主函數------------------->

from pymongo import MongoClient
from bson.objectid import ObjectId
from read_json  import read



def mongoclient():
    client = MongoClient('127.0.0.1', 27017)
    db = client.test
    collection = db.test
    # collection.insert({})
    # for i in collection.find({"name":"樂清市東岸北段"}):
    #      print(i)
    data = ('coastlines.real.json')
    find_Da = ('track')
    find_Id = ('coastlineid')
    find_Node = ('nodes_index')

    want_Data = read(data, find_Da)  #傳入json文件，根據關鍵字查詢
    want_Id = read(data, find_Id)
    want_No = read(data, find_Node)
    id = {'_id': ObjectId(want_Id)}
    id_print = collection.find_one(id)
    print(id_print)

    collection.update((id), {'$set': {'track': want_Data}})   #根據ObjectID修改track
    collection.update((id), {'$push': {'nodeindex': want_No}})  #根據ObjectID添加nodeindex
    collection.update((id), {'$set': {'nodeindex': want_No}})   #根據ObjectID修改nodeindex ,去除多余的[]


    id_change = collection.find_one(id)   #調出修改后的數據
    print("修改后:")
    print(id_change)




if __name__ =='__main__':
    mongoclient()

<---------------讀取文件代碼----------------------->

import json

def read(data, find):
    # 設置以utf-8解碼模式讀取文件，encoding參數必須設置，否則默認以gbk模式讀取文件，當文件中包含中文時，會報錯
    f = open(data, encoding='utf-8')
    setting = json.load(f)

    # 注意多重結構的讀取語法
    # family = setting['BaseSettings']['font']
    style = setting[find]


    # print(family)
    return style
