我正在尝试从PGA.com网站上获取数据,以获得美国所有高尔夫球场的表格。在我的CSV表格中,我想要包括高尔夫球场的名称,地址,所有权,网站,电话号码。有了这些数据,我想对其进行地理编码并放入地图并在我的计算机上安装本地副本
我利用Python和Beautiful Soup4来提取我的数据。我已经达到了提取数据并将其导入CSV的目的,但我现在遇到了从PGA网站上的多个页面中抓取数据的问题。我想提取所有高尔夫课程,但我的剧本仅限于一页我想要将其循环播放,它将从PGA网站的所有页面中捕获高尔夫球场的所有数据。大约有18000个黄金课程和900个页面来捕获数据
下面是我的剧本。我需要有关创建代码的帮助,这些代码将从PGA网站捕获所有数据,而不仅仅是一个站点而是多个站点。通过这种方式,它将为我提供美国所有黄金课程的数据。
以下是我的脚本:
import csv
import requests
from bs4 import BeautifulSoup
url = "http://www.pga.com/golf-courses/search?searchbox=Course+Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0"
r = requests.get(url)
soup = BeautifulSoup(r.content)
g_data1=soup.find_all("div",{"class":"views-field-nothing-1"})
g_data2=soup.find_all("div",{"class":"views-field-nothing"})
courses_list=[]
for item in g_data2:
try:
name=item.contents[1].find_all("div",{"class":"views-field-title"})[0].text
except:
name=''
try:
address1=item.contents[1].find_all("div",{"class":"views-field-address"})[0].text
except:
address1=''
try:
address2=item.contents[1].find_all("div",{"class":"views-field-city-state-zip"})[0].text
except:
address2=''
try:
website=item.contents[1].find_all("div",{"class":"views-field-website"})[0].text
except:
website=''
try:
Phonenumber=item.contents[1].find_all("div",{"class":"views-field-work-phone"})[0].text
except:
Phonenumber=''
course=[name,address1,address2,website,Phonenumber]
courses_list.append(course)
with open ('filename5.csv','wb') as file:
writer=csv.writer(file)
for row in courses_list:
writer.writerow(row)
#for item in g_data1:
#try:
#print item.contents[1].find_all("div",{"class":"views-field-counter"})[0].text
#except:
#pass
#try:
#print item.contents[1].find_all("div",{"class":"views-field-course-type"})[0].text
#except:
#pass
#for item in g_data2:
#try:
#print item.contents[1].find_all("div",{"class":"views-field-title"})[0].text
#except:
#pass
#try:
#print item.contents[1].find_all("div",{"class":"views-field-address"})[0].text
#except:
#pass
#try:
#print item.contents[1].find_all("div",{"class":"views-field-city-state-zip"})[0].text
#except:
#pass
这个脚本一次只捕获20个,我希望在一个脚本中捕获所有1800个高尔夫球场和900个页面的脚本。

PGA网站的搜索有多个页面,网址遵循以下模式:
http://www.pga.com/golf-courses/search?page=1 # Additional info after page parameter here
这意味着您可以阅读页面内容,然后将页面值更改为1,并阅读下一页....依此类推。
import csv
import requests
from bs4 import BeautifulSoup
for i in range(907): # Number of pages plus one
url = "http://www.pga.com/golf-courses/search?page={}&searchbox=Course+Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0".format(i)
r = requests.get(url)
soup = BeautifulSoup(r.content)
# Your code for each individual page here
答案 1 :(得分:3)
如果您仍然阅读此帖子,也可以尝试使用此代码....
from urllib.request import urlopen
from bs4 import BeautifulSoup
file = "Details.csv"
f = open(file, "w")
Headers = "Name,Address,City,Phone,Website\n"
f.write(Headers)
for page in range(1,5):
url = "http://www.pga.com/golf-courses/search?page={}&searchbox=Course%20Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0".format(page)
html = urlopen(url)
soup = BeautifulSoup(html,"html.parser")
Title = soup.find_all("div", {"class":"views-field-nothing"})
for i in Title:
try:
name = i.find("div", {"class":"views-field-title"}).get_text()
address = i.find("div", {"class":"views-field-address"}).get_text()
city = i.find("div", {"class":"views-field-city-state-zip"}).get_text()
phone = i.find("div", {"class":"views-field-work-phone"}).get_text()
website = i.find("div", {"class":"views-field-website"}).get_text()
print(name, address, city, phone, website)
f.write("{}".format(name).replace(",","|")+ ",{}".format(address)+ ",{}".format(city).replace(",", " ")+ ",{}".format(phone) + ",{}".format(website) + "\n")
except: AttributeError
f.close()
写入范围(1,5)只需将其更改为0,到最后一页,您将获得CSV中的所有详细信息,我非常努力地以正确的格式获取您的数据,但这很难:)。
答案 2 :(得分:2)
您正在为单个页面添加链接,它不会自行迭代每个页面。
第1页:
url = "http://www.pga.com/golf-courses/search?searchbox=Course+Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0"
第2页:
http://www.pga.com/golf-courses/search?page=1&searchbox=Course%20Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0
第907页:
http://www.pga.com/golf-courses/search?page=906&searchbox=Course%20Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0
由于您正在为第1页运行,因此您只能获得20分。您需要创建一个贯穿每个页面的循环。
您可以通过创建一个执行一个页面的函数然后迭代该函数来开始。
在网址search?
之后,从第2页开始,page=1
开始增加,直到第907页page=906
。

我注意到第一个解决方案重复了第一个实例,这是因为0页和1页是同一页。通过在范围功能中指定起始页面可以解决此问题。下面的示例...
for i in range(1, 907): #Number of pages plus one
url = "http://www.pga.com/golf-courses/search?page={}&searchbox=Course+Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0".format(i)
r = requests.get(url)
soup = BeautifulSoup(r.content, "html5lib") #Can use whichever parser you prefer
# Your code for each individual page here

遇到同样的问题,上述解决方案无效。我通过考虑Cookie解决了我的问题。请求会话会有所帮助。创建一个会话,然后通过向所有编号的页面插入cookie来拉出所需的所有页面。
import csv
import requests
from bs4 import BeautifulSoup
url = "http://www.pga.com/golf-courses/search?searchbox=Course+Name&searchbox_zip=ZIP&distance=50&price_range=0&course_type=both&has_events=0"
s = requests.Session()
r = s.get(url)

PGA网站已更改,已询问此问题。
似乎他们通过以下方式来组织所有课程:州>城市>课程
鉴于这种变化和此问题的普遍性,以下是我今天如何解决此问题的方法。
第1步-导入我们需要的所有内容:
import time
import random
from gazpacho import Soup # https://github.com/maxhumber/gazpacho
from tqdm import tqdm # to keep track of progress
第2步-清除所有状态URL端点:
URL = "https://www.pga.com"
def get_state_urls():
soup = Soup.get(URL + "/play")
a_tags = soup.find("ul", {"data-cy": "states"}, mode="first").find("a")
state_urls = [URL + a.attrs['href'] for a in a_tags]
return state_urls
state_urls = get_state_urls()
第3步-编写用于刮除所有城市链接的函数:
def get_state_cities(state_url):
soup = Soup.get(state_url)
a_tags = soup.find("ul", {"data-cy": "city-list"}).find("a")
state_cities = [URL + a.attrs['href'] for a in a_tags]
return state_cities
state_url = state_urls[0]
city_links = get_state_cities(state_url)
第4步-编写函数以刮擦所有课程:
def get_courses(city_link):
soup = Soup.get(city_link)
courses = soup.find("div", {"class": "MuiGrid-root MuiGrid-item MuiGrid-grid-xs-12 MuiGrid-grid-md-6"}, mode="all")
return courses
city_link = city_links[0]
courses = get_courses(city_link)
第5步-编写函数以解析有关课程的所有有用信息:
def parse_course(course):
return {
"name": course.find("h5", mode="first").text,
"address": course.find("div", {'class': "jss332"}, mode="first").strip(),
"url": course.find("a", mode="first").attrs["href"]
}
course = courses[0]
parse_course(course)
第6步-遍历所有内容并保存:
all_courses = []
for state_url in tqdm(state_urls):
city_links = get_state_cities(state_url)
time.sleep(random.uniform(1, 10) / 10)
for city_link in city_links:
courses = get_courses(city_link)
time.sleep(random.uniform(1, 10) / 10)
for course in courses:
info = parse_course(course)
all_courses.append(info)
