Question

我在尝试执行代码时遇到很多错误：

import requests
#import bs4 --not sure if it's necessary
from bs4 import BeautifulSoup
core = 'http://wwww.lolnexus.com'
name = input('\nName: ')
region =  input('\nRegion NA | EUW | EUNE | BR | TR | RU | LAN | LAS | OCE : ')
full = core + '/' + region + '/' + 'search?name=' + name + '&region=' + region
print (full)
r = requests.get(full)
source = r.text
soup = BeautifulSoup(source)
print (source)
input()

我不知道出了什么问题。它是应用程序的开始，我尝试编写并且错误阻止我抓取网页的其余部分。

我得到的错误：

Name: Fred

Region NA | EUW | EUNE | BR | TR | RU | LAN | LAS | OCE : TR
http://wwww.lolnexus.com/TR/search?name=Fred&region=TR

有什么不对，使用Requests＆amp; amp;是一个好主意。用于网页抓取的BeautifulSoup库？

Answer 1

您正尝试使用域名中的四个 http://wwww.lolnexus.com/TR/search?name=Fred&region=TR字符连接w。那个名字不存在。

更正主机名：

core = 'http://www.lolnexus.com'

发出请求@python
