学习pythone爬虫爬取免费简历为什么下载到文件夹的文件不是rar格式

Question

本来现在pythone爬虫，学习的一个案例中爬取某网站免费简历模版，自己写的代码如下

```python
import requests
from lxml import etree
import os

url = 'https://sc.chinaz.com/jianli/free.html'
headers = {'user-agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36'}

page_text = requests.get(url=url,headers=headers).text
tree = etree.HTML(page_text)
# with open('./jianli.html','w',encoding='utf-8') as fp:
#  fp.write(page_text)
a_list = tree.xpath('//div[@id="container"]/div/a')
if not os.path.exists('./resume'):
    os.mkdir('resume')

resume_list = []
for a in a_list:
    resume_src = 'http:'+a.xpath('./@href')[0]
    resume_name = a.xpath('./img/@alt')[0]
    resume_name = resume_name.encode('iso-8859-1').decode('utf-8')
    download_resume_src = resume_src+'#down'
    #print(resume_name,resume_src)
    resume_list.append(download_resume_src)
    #print(download_resume_src)
    download_text = requests.get(url=download_resume_src,headers=headers).text
    tree = etree.HTML(download_text)
    download_list = tree.xpath('.//div[@id="down"]/div[2]/ul/li/a/@href')[0]
    print(download_list)
    download_data = requests.get(url=download_list,headers=headers).content
    resume_path = 'resume/'+ resume_name
    with open(resume_path,'wb') as fp:
     fp.write(download_data)
    print(resume_name,'下载成功！')

运行结果显示：

原网站简历下载格式为.rar，但我执行后文件夹下保存的下载文件不是rar格式。
请教大家给予指点！感谢！

    resume_path = 'resume/'+ resume_name+".rar"#后缀加上
