Question

我有一个csv文件，其中包含标题行和100k条目。

我在python IDE和pycharm中使用conda作为python解释器。 conda将pymongo-3.4.0视为mongo-driver。

我解析我的csv文件并将其保存为磁盘上的json n文件，然后遍历json文件以在{{{{}}中插入json个对象1}}数据库。

JSON看起来像这样：

mongo

Python代码：

{
  a1 : {'name': 702104534, type='Single' }
  a2 : {'name': 702104535, type='Single' }
  a3 : {'name': 702104536, type='Married' }
}

通过以下错误：

import pymongo
import pickle

with open('my_json_file.json', 'rb') as in_file:
    person_json = pickle.load(in_file)

conn = pymongo.MonogClient('localhost','27017')
db = conn['db']
coll = db['coll']

persons = person_json.keys()
for person in persons:
    coll.insert_one(person_json[person])

但是，如果json字符串是变量

，同样有效

Python代码：

Traceback (most recent call last):
File "C:/PyCharmWorkSpace/LCR/json2mongo.py", line 109, in <module>
    data2mongo()
File "C:/PyCharmWorkSpace/LCR/json2mongo.py", line 89, in data2mongo

感谢您的帮助。

当pymongo字符串为json在动态生成或从基于磁盘的文件中读取json时，mongodb会出现一些运行时类型转换兼容性问题>使用插入方法插入到insert，例如insert_one或insert_many或json。

通过关联标准python类型转换，我能够将mongodb对象插入<div *ngFor="let post of objectKeys(_postArrayMatch.team1)"> <div> Team1: {{ _postArrayMatch.team1[post]}}</div> </div>。
