从网站(JSON)获取JSON [英] Get JSON from website (instagram)

问题描述

我最近想到了从instagram帐户及其帖子中抓取信息的想法，例如评论数或喜欢数.到目前为止，我发现在chrome中调试时发现了例如链接 https:/网络"标签下的/www.instagram.com/instagram/?__a 返回带有所需信息的JSON，但实际加载的内容仍然是正常的网站html代码.

I recently got the idea to scrape information from instagram accounts and their posts, like the amount of comments or amount of likes. I got so far that I figured out while debugging in chrome that for example the link https://www.instagram.com/instagram/?__a under the network tab returns a JSON with the wanted information, but what is actually loaded is still the normal website html code.

到目前为止，我在python中使用以下代码进行了尝试:

so far I tried in python with this code:

import urllib.request
r = urllib.request.urlopen(url)
print(r.read())

或在javascript中:

or in javascript :

window.onload = function () {
    res = fetch("https://www.instagram.com/instagram/?__a", {
        method: 'get'
    }).then(function (data) {
        return data.json();
    }).catch(function (error) {
        console.log("ERROR".concat(error.toString()));
    });
    console.log(res.user);
};

所以我的问题是，当使用这些功能时，我仅获取网站代码( html )，有没有办法仅获取后台加载的JSON?我知道人们会推荐我使用instagram api，但是我没有网站或公司要注册.

So the problem I have, is that when using these functions I only get the website code (html), is there a way to only get the JSON which is loaded in the background? I know people will recommend me using the instagram api, but I have no website nor a company to register.

推荐答案

我遇到了一个问题，试图使API达到我想要的目的，实际上只需要JSON数据，包括用于特定帐户的图像的URL和标题.

I ran into a problem trying to get the API to do what I wanted, and really just needed JSON data including urls and captions for images for a specific account.

使用以下GET请求:

https://www.instagram.com/account_name/?__a=1

其中account_name是我要抓取的配置文件.

where account_name is the profile I'm scraping.

它返回我执行任务所需的所有JSON.

It returns all JSON I needed for my task.
