ConnectionResetError: [WinError 10054] 远程主机强迫关闭了一个现有的连接。

分析：出现这种原因代表远程过于频繁，所以远程怀疑是恶意攻击，我是出现在远程图片下载时的错误，我在网上找到的方法如下：

【Python爬虫错误】ConnectionResetError: [WinError 10054] 远程主机强迫关闭了一个现有的连接

我个人的解决是使用函数回调解决的

意思就是当程序因为远程主机强制关闭而报错时，使用try- except在报错时从新调用该方法使其重新抓取，直至抓取成功，一般一两次就会成功，效率还算可以

源代码：

import os

import random

import urllib.request

def imgdon(url):

    img_url = url

    file_path = 'D:/book/tvimg/'

    file_name = "tvimg" + str(int(random.uniform(20, 10) * 10 ** 14))

    # 是否有这个路径

    if not os.path.exists(file_path):

        # 创建路径

        os.makedirs(file_path)

        # 获得图片后缀

    file_suffix = os.path.splitext(img_url)[1]

    # print(file_suffix)

    # 拼接图片名（包含路径）

    # filename = '{}{}{}{}'.format(file_path, os.sep, file_name, file_suffix)

    filename = file_path + file_name + file_suffix

    print(filename)

    # 下载图片，并保存到文件夹中

    urllib.request.urlretrieve(img_url, filename=filename)

    return "http://www.klkj1999.top:8081/tvimg/"+file_name + file_suffix

print(imgdon("http://tupian.tupianzy.com/pic/upload/vod/2018-11-12/201811121542011934.jpg"))

解决后的结果：
