连接mongoDB根据ObjectID写入json数据（初步）

from pymongo import MongoClientfrom bson.objectid import ObjectIdimport json

def read(data, find):    # 设置以utf-8解码模式读取文件，encoding参数必须设置，否则默认以gbk模式读取文件，当文件中包含中文时，会报错    f = open(data, encoding=‘utf-8‘)    setting = json.load(f)

# 注意多重结构的读取语法    # family = setting[‘BaseSettings‘][‘font‘]    style = setting[find]

# print(family)    return style

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