使用 Python 下载 instagram 视频(Reels)

Python 有很多非常棒的开源工具软件包可以抓取互联网上的页面，甚至包括网页中的图片以及视频。

今天来给大家介绍一款名为 instaloader 的 Python 开源工具，使用它能够从 Instagram 中提取并下载视频、图像、个人资料头像、帖子和评论等数据，并允许自定义筛选你感兴趣的媒体和元数据。非常强大！

instaloader 主要功能：

下载个人资料、标签、用户故事、摘要和保存的媒体。
下载每个帖子下方的评论和地理位置标签。
自动检测配置文件名称的变更，并重命名目标目录。
允许对过滤器进行细粒度定制，以及自定义下载资料的存储位置。
遍历抓取及下载个人账户中所有图片和视频，以及个人头像(需登陆对应 instagram 账户)。

安装 instaloader

请在终端执行命令：

pip3 install instaloader

遍历抓取 instagram 账户内所有内容

安装完成后，请创建一个名为 instasave.py 的 Python 文件，然后输入以下代码：

import instaloader
from datetime import datetime
from itertools import dropwhile, takewhile
import csv

class GetInstagramProfile():
    def __init__(self) -> None:
        self.L = instaloader.Instaloader()

    def download_users_profile_picture(self,username):
        self.L.download_profile(username, profile_pic_only=True)

    def download_users_posts_with_periods(self,username):
        posts = instaloader.Profile.from_username(self.L.context, username).get_posts()
        SINCE = datetime(2021, 8, 28)
        UNTIL = datetime(2021, 9, 30)

        for post in takewhile(lambda p: p.date > SINCE, dropwhile(lambda p: p.date > UNTIL, posts)):
            self.L.download_post(post, username)

    def download_hastag_posts(self, hashtag):
        for post in instaloader.Hashtag.from_name(self.L.context, hashtag).get_posts():
            self.L.download_post(post, target='#'+hashtag)

    def get_users_followers(self,user_name):

        profile = instaloader.Profile.from_username(self.L.context, user_name)
        file = open("follower_names.txt","a+")
        for followee in profile.get_followers():
            username = followee.username
            file.write(username + "\n")
            print(username)

        self.L.login(input("input your username: "), input("input your password: ") ) 
        profile = instaloader.Profile.from_username(self.L.context, user_name)
        file = open("following_names.txt","a+")
        for followee in profile.get_followees():
            username = followee.username

                print("comment.id  : "+str(comment.id))
                print("comment.owner.username  : "+comment.owner.username)
                print("comment.text  : "+comment.text)
                print("comment.created_at_utc  : "+str(comment.created_at_utc))
                print("************************************************")

    def get_post_info_csv(self,username):
        with open(username+'.csv', 'w', newline='', encoding='utf-8') as file:
            writer = csv.writer(file)

            for post in posts:

                print("post profile: "+post.profile)
                print("post caption: "+post.caption)
                print("post location: "+str(post.location))
                
                posturl = "https://www.instagram.com/p/"+post.shortcode
                print("post url: "+posturl)
                writer.writerow(["post",post.mediaid, post.profile, post.caption, post.date, post.location, posturl,  post.typename, post.mediacount, post.caption_hashtags, post.caption_mentions, post.tagged_users, post.likes, post.comments,  post.title,  post.url ])
            
                for comment in post.get_comments():
                    writer.writerow(["comment",comment.id, comment.owner.username,comment.text,comment.created_at_utc])
                    print("comment username: "+comment.owner.username)
                    print("comment text: "+comment.text)
                    print("comment date : "+str(comment.created_at_utc))
                print("\n\n")


if __name__=="__main__":
    cls = GetInstagramProfile()
    #cls.download_users_profile_picture("best_gadgets_2030")
    #cls.download_users_posts_with_periods("best_gadgets_2030")
    #cls.download_hastag_posts("gadgets")

    cls.get_post_info_csv("coolest.gadget")

由于以上代码涉及遍历抓取用户所有数据，所以您需要输入对应用户账户用户名和密码才可进行操作（您可以用作自己账户的数据备份）。
