我正在创建一个脚本，但是有一些问题与其中的一部分，所以我将只粘贴那部分而不是所有脚本..无论如何，这个唯一的部分也可以单独工作。这是：
import re, random, os.path, urllib.request
from bs4 import BeautifulSoup
def proxyget():
if os.path.isfile("proxy.txt"):
out_file = open("proxy.txt","w")
out_file.write("")
out_file.close()
else:
pass
url = "https://www.inforge.net/xi/forums/liste-proxy.1118/"
soup = BeautifulSoup(urllib.request.urlopen(url), "lxml")
base = "https://www.inforge.net/xi/"
for tag in soup.find_all("a", {"class":"PreviewTooltip"}):
links = tag.get("href")
final = base + links
result = urllib.request.urlopen(final)
for line in result :
ip = re.findall("(?:[\d]{1,3})\.(?:[\d]{1,3})\.(?:[\d]{1,3})\.(?:[\d]{1,3}):(?:[\d]{1,5})", str(line))
if ip:
print("Proxy grabbed=> "+'\n'.join(ip))
for x in ip:
out_file = open("proxy.txt","a")
while True:
out_file.write(x+"\n")
out_file.close()
break
def withproxy():
try:
out_file = str(input("Enter the proxy list: "))
with open(out_file) as x:
proxylist = list(x)
for y in proxylist:
proxylist = y.split('\n')
proxy = random.choice(proxylist).split(':')
except:
print ("Error to read file, try again")
withproxy()
host = proxy[0]
port = int(proxy[1])
proxyget()
withproxy()
我不明白为什么有时候这部分代码会起作用，有时会出现这个错误：
Proxy grabbed=> x.x.x.x:x
Enter the proxy list: proxy.txt
Traceback (most recent call last):
File "proxytry.py", line 44, in <module>
withproxy()
File "proxytry.py", line 41, in withproxy
port = int(proxy[1])
IndexError: list index out of range
这有什么问题？你能帮帮我吗？

在列表末尾创建一个空字符串proxylist = y.split('\n')
，以便''。
因此，当proxylist = [..., '']选择列表中的某个项目时，它会在某个时刻选择random.choice '' split返回包含一个项目的列表':' {1}}。
['']将提升 proxy[1]。
在您使用引用IndexError在列表上进行迭代时，我也不明白为什么名称proxylist正在循环中使用：
proxylist我很遗憾无法为您的代码生成一个可用的版本，因为我不确切地知道您正在阅读的文件的内容。我认为最好不要猜测。
答案 1 :(得分：2)
错误本身是直截了当的;虽然proxy末尾的withproxy支持下标，但它没有索引1.它可能是一个条目的列表，也可能是单个字符的列表。
快速浏览该点上方的正文可以看出proxy中可能根本没有设置withproxy;只有当它设法读取一个文件时才会发生这种情况（为什么它的名称为out_file，当纯粹的输入不清楚时），将其读作行（默认情况下迭代文件就像list一样这个案例），将'\n'上的那些分开（即使它们已经是行），然后在行中选择那些假设行的随机选择（它们不会发生;但除了可能是最后一行之外的每一行，那里'将是一个空字符串来选择），然后在冒号上拆分。
我认为你的意思更多的是：
entries = open(filename).readlines()
proxy = random.choice(entries).strip().split(':')
这将选择一个随机行，而不是在空字符串和每行的每一行之间随机选择。第二个问题是，except块中的递归调用根本没有设置proxy。
答案 2 :(得分：1)
我怀疑这将完全回答这个问题，但是，＆＃34;列出索引超出范围＆＃34;通常意味着你要求一个不存在的元素，记住，列表元素编号从0开始，所以在第41行：＆＃34; port = int（代理[1]）＆＃34;，＆＃34;代理[ 1]＆＃34;可能并不存在，这意味着列表＆＃34; proxy＆＃34;是空的还是包含一个元素。如果您想要第一个元素，请使用＆＃34; proxy [0]＆＃34;。
