百度了问题是无效的url，

运行结果及报错内容 requests.exceptions.MissingSchema: Invalid URL '写在连载前': No scheme supplied. Perhaps you meant http://写在连载前?
我的解答思路和尝试过的方法

百度了无效url，网址协议应该是对的

我想要达到的结果

```python

import requests
from lxml import etree
import os
from multiprocessing import Pool


def Chapterspider(self):

    """章节爬虫，参数传入目录，返回(章节名称， 对应页面链接)的列表"""
    headers = {

    content = requests.get(url, headers=headers).content
    html=etree.HTML(content)
    chapter_names=html.xpath('//dd/a/text()')
    chapter_links=html.xpath('//dd/a/@href')
    return chapter_names, chapter_links
def Chapterdownload(turple):
    """章节下载成对应的txt，这个url参数指每一页的链接，chapter_link"""
    url=turple[0]
    name=turple[1]
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.61 Safari/537.36'
    }
    rsp=requests.get(url,headers=headers)
    content=rsp.content

    content_list=html.xpath('//div[@id="content"]//text()')
    content_list=Remove_r(content_list,"\r")
    content_list=Formatlist(content_list)[:-2]
    dir_name="小说2"
    isExists=os.path.exists(dir_name)
    if not isExists:
        os.makedirs(dir_name)
    with open(dir_name+'/'+name+'.text','w',encoding='utf-8') as f:
        f.writelines(content_list)
    print(content_list)
    print(url)
    print(name,'爬取完毕')

def Remove_r(list,a):
    """去除列表中含字符串a的项"""
    while True:  # 无限循环，利用break退出
        if a not in list:
            break
        else:
            list.remove(a)
    return list


def Formatlist(list):
    """去除只有/r的项后，还要把每项的特殊字符去掉     和\r"""
    for i in range(len(list)):
        if '\r' in list[i]:
            list[i]=list[i].replace('\r','\n')
        if '\xa0\xa0\xa0\xa0' in list[i]:
            list[i]=list[i].repalce('\xa0\xa0\xa0\xa0', '')
    return list


if __name__ == '__main__':
    chapter_links=[]
    url="https://www.xbiquwx.la/10_10582/"
    chapter_names,chapter_links_before=Chapterspider(url)
    for i, j in zip (chapter_names,chapter_links_before):
        j=url+j
        chapter_links.append(j)
    print(chapter_links)
    # # 生成链接和章名一一对应的字典
    link_find_name=dict(zip(chapter_names,chapter_links))
    canshu=[]
    for link, name in link_find_name.items():
        canshu.append((link,name))
    pool = Pool(processes=4)
    pool.map(Chapterdownload, canshu)

写反了
