```python
import random
import string
def generate_session_id(length=32):
return ''.join(random.choices(string.ascii_letters + string.digits, k=length))
session_id = generate_session_id()
print(session_id)
```
```python
import uuid
def generate_session_id():
return str(uuid.uuid4())
session_id = generate_session_id()
print(session_id)
```
3. 基于时间戳
```python
import time
import random
def generate_session_id(length=32):
timestamp = int(time.time() 1000)
random_part = random.randint(0, 9999)
return f"{timestamp
