python中URL地址用.format转换后出错，提示JSONDecodeError("Expecting value", s, err.value) from None。
不转换的话没什么问题，url地址放在了address变量中（我用的是python3）
import urllib.request

from cons import cons
ssl._create_default_https_context = ssl._create_unverified_context
station_list = {}
for i in cons.split('@'):
if i:
temp_list = i.split('|')
station_list[temp_list[1]] = temp_list[2]
train_date = '2017-8-17'
from_station = station_list['北京']
to_station = station_list['上海']
print(train_date, from_station, to_station)
def get_list():
address = 'https://kyfw.12306.cn/otn/leftTicket/query?leftTicketDTO.train_date={0}' \
'&leftTicketDTO.from_station={1}' \
'&leftTicketDTO.to_station={2}&purpose_codes=ADULT'.format(train_date, from_station, to_station)
print(address)
url = urllib.request.Request(address)
url.add_header('User-Agent', 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko)'
' Chrome/45.0.2454.101 Safari/537.36')
html = urllib.request.urlopen(url).read()
dit = json.loads(html)
print(type(html))
print(type(dit))
return dit['data']['result']
# 车次3
# 出发时间8
# 到达时间9
# 历时 = 10
# 硬卧 =28
# 出发日期 13
for i in get_list():
temp_buy = i.split('|')
if temp_buy == '无' or temp_buy == ' ':
continue
else:
print(temp_buy) # buy
break
cost.py中的代码如下
