我已经构建了一个刮板来使用它们的api从songkick检索音乐会数据。但是，从这些艺术家中检索所有数据需要很长时间。大约15小时后，脚本仍在运行，但JSON文件不再改变。我中断了脚本，并检查了是否可以使用TinyDB访问我的数据。不幸的是我得到以下错误。有人知道为什么会发生这种情况吗？当从Songkick检索数据时出现内存错误
错误：
('cannot fetch url', 'http://api.songkick.com/api/3.0/artists/8689004/gigography.json?apikey=###########&min_date=2015-04-25&max_date=2017-03-01')

下面你可以找到我的剧本
import urllib2
import requests
import json
import csv
import codecs
from tinydb import TinyDB, Query
db = TinyDB('events.json')

MIN_DATE = "2015-04-25"

API_KEY= "###############"
with open('artistid.txt', 'r') as f:
for a in f:
artist = a.strip()
print(artist)
url_base = 'http://api.songkick.com/api/3.0/artists/{}/gigography.json?apikey={}&min_date={}&max_date={}'
url = url_base.format(artist, API_KEY, MIN_DATE, MAX_DATE)
# url = u'http://api.songkick.com/api/3.0/search/artists.json?query='+artist+'&apikey=WBmvXDarTCEfqq7h'
try:
r = requests.get(url)
resp = r.json()
if(resp['resultsPage']['totalEntries']):
results = resp['resultsPage']['results']['event']
for x in results:
print(x)
db.insert(x)
except:
print('cannot fetch url',url);
load_events()
db.close()
print ("End of script")
，但它是在你的错误的第一行可见。 – alxwrd
