今天发现,使用redis-py从redis中获取的数据竟然是加密的。
conn = redis.Redis(host=‘redis_serverip‘, port=6379, password=‘redis_password‘, db=0) conn.set(‘string-key1‘, ‘value1‘) result = conn.get(‘string-key1‘) print(‘result:‘, result) print(‘result type:‘, type(result)) print() result_decoded = result.decode(‘utf-8‘) print(‘result_decoded:‘, result_decoded) print(‘result_decoded type:‘, type(result_decoded)) print() result_str = str(result) print(‘result_str:‘, result_str) print(‘result_str type:‘, type(result_str)) print() print(‘test int in redis...\n‘) conn.set(‘string-key2‘, 100) result = conn.get(‘string-key2‘) print(‘result:‘, result) print(‘result type:‘, type(result)) print() result_decoded = int(result) print(‘result_decoded:‘, result_decoded) print(‘result_decoded type:‘, type(result_decoded))
输出:
result: b‘value1‘
result type: <class ‘bytes‘>
result_decoded: value1
result_decoded type: <class ‘str‘>
result_str: b‘value1‘
result_str type: <class ‘str‘>
test int in redis...
result: b‘100‘
result type: <class ‘bytes‘>
result_decoded: 100
result_decoded type: <class ‘int‘>
可以看出:
如果传入str,传出的是bytes,需要通过decode(‘utf-8‘)进行恢复。
如果传入int,传出的是bytes,需要通过int()进行恢复。
另一种解决办法是在创建redis client时,进行decode设置。
conn = redis.Redis(host=‘redis_serverip‘, port=6379, password=‘redis_password‘, db=0, decode_responses=True) conn.set(‘string-key3‘, ‘value3‘) result = conn.get(‘string-key3‘) print(‘result:‘, result) print(‘result type:‘, type(result)) print() print(‘test int in redis...\n‘) conn.set(‘string-key4‘, 100) result = conn.get(‘string-key4‘) print(‘result:‘, result) print(‘result type:‘, type(result)) print() result_decoded = int(result) print(‘result_decoded:‘, result_decoded) print(‘result_decoded type:‘, type(result_decoded))
输出:
result: value3
result type: <class ‘str‘>
test int in redis...
result: 100
result type: <class ‘str‘>
result_decoded: 100
result_decoded type: <class ‘int‘>
这种情况下,str是正常的,int需要注意一下。
