我的代码当前从 XML 文件(从网站获得)中为每个用户打印数据,随着更多用户全天与之交互,XML 会更新。我目前有我的代码循环以每 5 分钟下载一次此数据。
每次运行代码时,它都会生成一个用户列表及其统计信息,前 5 分钟它会打印用户:a,b,c
第二个 5 分钟打印用户:a,b,c,d,e
第三个 5 分钟打印用户:a,b,c,d,e,f,g
我需要代码来打印前 5 分钟:a、b、c 第二 5 分钟:d、e 第三 5 分钟:f、g
一些如何识别一些用户已经被使用。每个用户都有一个唯一的用户 ID,我猜它可以匹配吗?
我附上了我的代码示例,以防万一。
import mechanize
import urllib
import json
import re
import random
import datetime
from sched import scheduler
from time import time, sleep
######Code to loop the script and set up scheduling time
s = scheduler(time, sleep)
random.seed()
def run_periodically(start, end, interval, func):
event_time = start
while event_time < end:
s.enterabs(event_time, 0, func, ())
event_time += interval + random.randrange(-5, 45)
s.run()
###### Code to get the data required from the URL desired
def getData():
post_url = "URL OF INTEREST"
browser = mechanize.Browser()
browser.set_handle_robots(False)
browser.addheaders = [('User-agent', 'Firefox')]
######These are the parameters you've got from checking with the aforementioned tools
parameters = {'page' : '1',
'rp' : '250',
'sortname' : 'roi',
'sortorder' : 'desc'
}
#####Encode the parameters
data = urllib.urlencode(parameters)
trans_array = browser.open(post_url,data).read().decode('UTF-8')
xmlload1 = json.loads(trans_array)
pattern1 = re.compile('> (.*)<')
pattern2 = re.compile('/control/profile/view/(.*)\' title=')
pattern3 = re.compile('<span style=\'font-size:12px;\'>(.*)<\/span>')

##### Making the code identify each row, removing the need to numerically quantify the number of rows in the xmlfile,
##### thus making number of rows dynamic (change as the list grows, required for looping function to work un interupted)
for row in xmlload1['rows']:
cell = row["cell"]
##### defining the Keys (key is the area from which data is pulled in the XML) for use in the pattern finding/regex
user_delimiter = cell['username']
selection_delimiter = cell['race_horse']
if strikeratecalc2 < 12 : continue;
##### REMAINDER OF THE REGEX DELMITATIONS
username_delimiter_results = re.findall(pattern1, user_delimiter)[0]
userid_delimiter_results = (re.findall(pattern2, user_delimiter)[0])
user_selection = re.findall(pattern3, selection_delimiter)[0]
##### Printing the results of the code at hand
print "user id = ",userid_delimiter_results
print "username = ",username_delimiter_results
print "user selection = ",user_selection
print ""
getData()
run_periodically(time()+5, time()+1000000, 3000, getData)
请善待评论,我已经累计编码了 11 天,所以也请原谅我正在使用的代码中的任何重大错误,尽管到目前为止它正在工作。
亲切的问候
