Question

我在Windows 8 64位上使用Python.org版本2.7 64位。我有一些代码遍历一系列日期变量来创建网站的XHR提交。这些尝试为在迭代的日子里进行的比赛提取足球数据。如果没有播放任何匹配，那么今天会打印一条消息。

我的代码工作正常，除了它没有返回任何数据，除了最近一个季节。我试图抓的页面在这里：

http://www.whoscored.com/Regions/252/Tournaments/26

日历允许您在日期之间切换，XHR请求会在页面上填充此数据。我用来做这个的代码是：

from datetime import date, timedelta as td
from ast import literal_eval
from datetime import datetime
import requests
import time
import re

list1 = [2000,2001,2002,2003,2004,2005,2006,2007,2008,2009,2010,2011,2012,2013]
list2 = [2001,2002,2003,2004,2005,2006,2007,2008,2009,2010,2011,2012,2013,2014]


for x, y in zip(list1, list2):
    print "list1 - " + str(x)
    print "list2 - " + str(y)


    d1 = date(x,11,01)
    d2 = date(y,5,31)

    delta = d2 - d1



    for i in range(delta.days + 1):

        time1 =  str(d1 + td(days=i))
        time2 = time1.split("-", 1)[0]
        time3 = time1.split("-", -1)[1]
        time4 = time1.rsplit("-", 1)[-1]

        time2 = int(time2)
        time3 = int(time3)
        time4 = int(time4)

        date1 = datetime(year=time2, month=time3, day=time4)

        url = 'http://www.whoscored.com/tournamentsfeed/8273/Fixtures/'

        params = {'d': date1.strftime('%Y%m%d'), 'isAggregate': 'false'}
        headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.125 Safari/537.36'}

        response = requests.get(url, params=params, headers=headers)


        try:
            fixtures = literal_eval(response.content)


            if fixtures is not None and len(fixtures) > 0: # If there are fixtures
                print ",\n".join([", ".join(str(x) for x in fixture) for fixture in fixtures]) # `fixtures` is a nested list
                time.sleep(0.5)    


            else:

               print "No Fixtures Today: " + date1.isoformat()
               time.sleep(0.5) 

        except SyntaxError:

            print "Error!!!"
            time.sleep(0.5)

据我所知，所有可用季节的所有数据都应该通过相同的方法和相同的地方访问。谁能明白为什么这不起作用？

问题是每个赛季都有不同的锦标赛ID，这意味着网址不同。我将代码更改为适用于所有年份及其锦标赛ID

import json
import requests
import time

from datetime import date, timedelta

year_tournament_map = {
    2013: 8273,
    2012: 6978,
    2011: 5861,
    2010: 4940,
    2009: 3419,
    2008: 2689,
    2007: 2175,
    2006: 1645,
    2005: 1291,
    2004: 903,
    2003: 579,
    2002: 421,
    2001: 243,
    2000: 114,
    1999: 26,
}

years = sorted(year_tournament_map.keys())
url = 'http://www.whoscored.com/tournamentsfeed/%s/Fixtures/'
headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.125 Safari/537.36'}

for year in years:
    start_date = date(year, 11, 1)
    end_date = date(year + 1, 5, 31)
    delta = end_date - start_date

    for days  in range(delta.days + 1):
        time.sleep(0.5) 

        test_date = start_date + timedelta(days=days)

        params = {'d': str(test_date).replace('-', ''), 'isAggregate': 'false'}
        response = requests.get(url % year_tournament_map[year], params=params, headers=headers)

        try:
            json_data = response.content.replace("'", '"').replace(',,', ',null,')
            fixtures = json.loads(json_data)

        except ValueError:
            print "Error!!!"

        else:

            if fixtures:  # If there are fixtures
                print ",\n".join([", ".join(str(x) for x in fixture) for fixture in fixtures])  # `fixtures` is a nested list

            else:
               print "No Fixtures Today: %s" %  test_date

XHR请求不返回网站的所有数据
