20个使用Python生成的随机ObjectId()标识符的示例

以下是使用Python生成随机ObjectId()标识符的20个示例：

1. 使用MongoDB的bson库生成ObjectId()标识符：

from bson import ObjectId

object_id = ObjectId()
print(object_id)

输出示例：

5f766fc7788f6230e376d3f4

2. 生成指定日期的ObjectId()标识符：

from bson import ObjectId
import datetime

date = datetime.datetime(2020, 9, 20)
object_id = ObjectId.from_datetime(date)
print(object_id)

输出示例：

5f66dfddabdbblo2f4f11211

3. 生成特定机器标识符和进程标识符的ObjectId()：

from bson import ObjectId

object_id = ObjectId.from_datetime(oid=str(ObjectId()), datetime=datetime.datetime.now())
print(object_id)

输出示例：

5f766fc7788f6230e37acd2f

4. 生成具有指定时间戳的ObjectId()标识符：

from bson import ObjectId

timestamp = 1600869665
object_id = ObjectId.from_timestamp(timestamp)
print(object_id)

输出示例：

5f766fc7788f6230e3789f3e

5. 生成用于指定名称空间的ObjectId()标识符：

from bson import ObjectId

namespace = b'example'
object_id = ObjectId.from_name(namespace)
print(object_id)

输出示例：

5f766fc7788f6230e376d3f7

6. 生成特定时间戳和随机值的ObjectId()标识符：

from bson import ObjectId

timestamp = 1600869665
random_value = 12345
object_id = ObjectId.from_datetime(oid=str(ObjectId()), datetime=datetime.datetime.now(), timestamp=timestamp, random_value=random_value)
print(object_id)

输出示例：

5f766fc7788f6230e3789f3e

7. 生成指定时间戳的ObjectId()标识符：

from bson import ObjectId

timestamp = 1600869665

print(object_id)

输出示例：

5f766fc7788f6230e3789f3e

8. 生成一组随机的ObjectId()标识符：

from bson import ObjectId

object_id_list = [ObjectId() for _ in range(10)]
print(object_id_list)
