我试图用python requests抓取**google-lens**，但找不到上传图像的请求或如何解码。
请求（其答案是图像分析）如下：

import requests

cookies = {
    'CONSENT': 'PENDING+XXX',
    'SOCS': 'XXXXXXXXXXXXXXXXXXXXXXXXXXX',
    'HSID': 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',

    '__Secure-1PSIDCC': 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',

}

    cookies=cookies,

)

url中的p参数在我看来像是数据，但是：

也许太短的图像？
我无法将字符串Base64解码为图像。有什么想法吗？

p在我的例子中是：

在网络选项卡上传图像时，我找不到任何其他数据请求。
另外，我如何使用python将图像编码为这样的字符串？

正如你所猜测的，数据似乎太短的图像（在基地64格式或其他编码）.我们不能肯定地告诉发生了什么事在谷歌图像搜索内部程序，但以下情况浮现在脑海中（通常这样的搜索系统的工作原理是这样的）：
用户首先将图像上传到Google透镜，然后Google在其内部数据库中为上传的图像分配一个ID。您将在搜索URL和代码中看到该ID作为p参数。然后图像搜索使用该ID引用其内部数据库中上传的图像。
只是为了确保像p这样的小字符串不能容纳整个图像，运行base64.b64encode(open('path/to/image.png', 'rb').read())，结果是一个很长的字符串。
如果您更精确地拦截Google Chrome中的网络选项卡，您会注意到用户首先被重定向到类似https://lens.google.com/upload&re=df&st=some_number_hereplm=intenal_database_identifier的地址，然后用户将被重定向到地址栏中带有p参数的主搜索页面。
因此，为了使用谷歌图像搜索最好的解决方案是使用官方的API和库，如this。但如果你坚持使用非官方的方式，像selenium这样的东西可以像浏览器一样运行，并获得你正在寻找的参数。

作为替代方案，还有SerpApi的Google Lens API。这是一个付费API，有一个免费的计划，可以在其后端处理和解析块。
为了上传图像，您需要指定其url：

params = {
  "url": "https://i.imgur.com/HBrB8p0.png", # URL of an image to perform the Google Lens search
  # other parameters
}

检查在线IDE中的简单代码。

from serpapi import GoogleSearch
import json

params = {
  "engine": "google_lens",                  # search engine. Google, Bing, Yahoo, Naver, Baidu...
  "url": "https://i.imgur.com/HBrB8p0.png", # URL of an image to perform the Google Lens search
  "api_key": "..."                          # serpapi key, https://serpapi.com/manage-api-key
}

search = GoogleSearch(params)               # where data extraction happens on the backend
results = search.get_dict()                 # JSON -> Python dict
visual_matches = results["visual_matches"]

print(json.dumps(visual_matches, indent=2, ensure_ascii=False))

输出示例：

{
    "position": 1,
    "title": "File:Danny DeVito by Gage Skidmore.jpg - Wikipedia",
    "link": "https://en.wikipedia.org/wiki/File:Danny_DeVito_by_Gage_Skidmore.jpg",
    "source": "wikipedia.org",

  },

    "title": "Danny DeVito - Wikipèdia",
    "link": "https://oc.wikipedia.org/wiki/Danny_DeVito",
    "source": "wikipedia.org",

  },

您可以转到Google Lens playground尝试不同的图像上传选项。
