Pymongo bson.errors.InvalidDocument:从文件读取时无法编码对象

Question

我有一个csv文件，其中包含标题行和 100k 个条目。

我在 IDE 中使用pythonpycharm并将conda用作 python 解释器。condapymongo-3.4.0mongo-driver.

我解析我的csv文件并将其另存为磁盘上的jsonn个文件，然后循环访问json文件以将json对象插入mongo数据库中。

JSON 如下所示：

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

蟒蛇代码：

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])

通过以下错误：

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

File "C:Anaconda3libsite-packagespymongonetwork.py", line 94, in command
None, codec_options, check_keys)
bson.errors.InvalidDocument: Cannot encode object: 702104534

但是，如果 json 字符串是一个变量，则同样有效

蟒蛇代码：

import pymongo
conn = pymongo.MonogClient('localhost','27017')
db = conn['db']
coll = db['coll']
person = {'name': 702104534, 'type'='Single' }
coll.insert_one(person)

感谢您的帮助。

当动态生成或从基于磁盘的文件读取json时，当使用insert或insert_one或insert_many任一插入方法将json字符串插入到mongodb时，pymongo似乎存在一些运行时类型转换兼容性问题。

我能够通过关联标准 python 类型转换将json对象插入到mongodb。
