Python下载带有变化变量的图像

Question

我想从其中包含import urllib.request import random random_number=random.randint(500,600) url_image="'https://csgostash.com/img/skins/s"+str(random_number)+"fn.png'" image=urllib.request.urlretrieve(url_image, 'skin.png') 的网址链接下载图片，因此我生成了相同的代码，但我收到了错误 -

代码：

Answer 1

首先，url_image有一种奇怪的语法。

refresh fast

如果你解决了这个问题，你会发现403-Vax！防范僵尸：使用用户代理。

    url_image="https://csgostash.com/img/skins/s"+str(random_number)+"fn.png"

编辑：当然你可以保存到文件：

import urllib.request
import random

random_number=random.randint(500,600)
url_image="https://csgostash.com/img/skins/s"+str(random_number)+"fn.png"

user_agent = 'Mozilla/5.0 (Windows NT 6.1; Win64; x64)'
headers = {'User-Agent': user_agent}
req = urllib.request.Request(url_image, None, headers)


print(url_image)
#image, h = urllib.request.urlretrieve(url_image)
with urllib.request.urlopen(req) as response:
    the_page = response.read()

print (the_page)

Answer 2

使用请求检出this project。
