python requests 在linux服务器获取数据返回403，但，本地可以获取

最近学习python爬虫，遇到个不太好解决的问题，
望好心耐心解答，
以下代码

import requests
import time
import re
from bs4 import BeautifulSoup

v = input("URL:")


head = {
    'method': 'GET',
    'upgrade-insecure-requests': '1',
    'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36',
    'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
    'sec-fetch-site': 'none',
    'sec-fetch-mode': 'navigate',
    'sec-fetch-dest': 'document',
    'accept-language': 'zh-CN,zh;q=0.9',
    'connection': 'close'
}

requestCoding = {}


def getPage(url, start):
     try:
         resp = requests.get(url, headers=head, timeout=(5, 10))
         resp.encoding = getEncoding(resp)
         if resp.status_code == 200:
            html = BeautifulSoup(resp.text, 'html.parser')
            page = html.find('head')
            print(abs(round(start - time.time(), 2)), page)
         else:
            print(abs(round(start - time.time(), 2)), resp.status_code)
     except Exception as message:
            print('requests Error:', message, '耗时：', abs(round(start - time.time(), 2)), )


def getEncoding(resp):
    try:
        appCode = resp.apparent_encoding
        htmlCode = requests.utils.get_encodings_from_content(resp.text)[0]
        if appCode:
            requestCoding['appCode'] = appCode
            requestCoding['htmlCode'] = htmlCode
            if appCode != htmlCode:
                iso = re.search('ISO-8859', appCode, re.IGNORECASE)
                win = re.search('Windows', appCode, re.IGNORECASE)
                if iso:
                    return 'GBK'
                if win:
                    return 'utf-8'
                else:
                    return appCode
        else:
            return htmlCode
    except:
        requestCoding['manualSet'] = 'utf-8'
        return requestCoding['manualSet']


if __name__ == '__main__':
    main_start = time.time()
    print(getPage(v, main_start))

可能是requests伪造的头部信息不全。
要在headers中添加抓包时的请求头参数

比如

url = "https://xxxxxxxxxxx"
headers={
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 UBrowser/6.2.4098.3 Safari/537.36',
    'Host' : 'xxxxxxxxxxx',
    'Origin' : 'xxxxxxxxxxxxx',
    'Referer' : 'xxxxxxxxxxxxxx',
    'Cookie': 'xxxxxxxxxxxxxxxx'
}
res = requests.get(url,headers=headers)

其中请求头的参数 'User-Agent','Host','Origin', 'Referer','Cookie'可以在浏览器的f12控制台的Network中看到

几行代码的事为啥写这么多呢

估计被反爬了，请求头加cookie，refer试试

我也遇到过，换header, 代理ip都没有用的那种，楼主解决问题了吗
