RIGHT get_redditor() 慢？

Question

有没有人注意到大虾的get_redditor()方法有点慢？我昨天开始使用它，当我开始注意到速度下降时我决定做一些测试。我使用以下代码：

import praw
import time

time1 = 0
time2 = 0

print('Initial reddit setup')
time1 = int(round(time.time() * 1000))
user_agent = ('Reddit Checker 0.1 by /u/NinjaXI')
r = praw.Reddit(user_agent)
time2 = int(round(time.time() * 1000))
print(time1)
print(time2)
print(time2 - time1)
print('===================================================================')

print('Get Subreddit Python')
time1 = int(round(time.time() * 1000))
pythonSub = r.get_subreddit('Python')
time2 = int(round(time.time() * 1000))
print(time1)
print(time2)
print(time2 - time1)
print('===================================================================')

print('Get hot 10')
time1 = int(round(time.time() * 1000))
pythonSub.get_hot(limit=10)
time2 = int(round(time.time() * 1000))
print(time1)
print(time2)
print(time2 - time1)
print('===================================================================')

print('Get Redditor NinjaXI')
time1 = int(round(time.time() * 1000))
me = r.get_redditor('NinjaXI')
time2 = int(round(time.time() * 1000))
print(time1)
print(time2)
print(time2 - time1)
print('===================================================================')

print('Get submitted 10')
time1 = int(round(time.time() * 1000))
me.get_submitted(limit=10)
time2 = int(round(time.time() * 1000))
print(time1)
print(time2)
print(time2 - time1)
print('===================================================================')

这输出：

如您所见，使用 get_redditor() 比 get_subreddit() 花费（在此运行）2.6 秒。每次平均时间在 2 到 2.6 秒之间，但 get_subreddit() 仅高达 1 毫秒。我在做什么吗？这是 praw/reddit api 的已知问题吗？我可以做些什么来加快速度吗？

Answer 1

PRAW 的 getter 通常 return lazy objects，这意味着它们仅在您实际尝试使用该对象时才从 Reddit 的服务器请求数据。这与您非常快速的函数调用是一致的——一切都在本地发生。您的 get_redditor() 调用可能正在立即请求数据（虽然我不能说为什么；根据文档，它也应该是惰性的）。
