使用pymongo在mongodb中存储特殊字符

import pymongo

# 连接MongoDB数据库
client = pymongo.MongoClient("mongodb://localhost:27017/")
db = client["mydatabase"]
collection = db["mycollection"]

# 存储特殊字符
special_char = "特殊字符: @#$%^&*()_+{}[]|\\;:'\"<>,.?/~`"
escaped_char = special_char.replace("\\", "\\\\").replace("$", "\\$")
encoded_char = escaped_char.encode("utf-8")

data = {"special_char": encoded_char}
collection.insert_one(data)

# 查询特殊字符
result = collection.find_one({"special_char": encoded_char})
decoded_char = result["special_char"].decode("utf-8")
print(decoded_char)
