问题描述
我正在使用 Selenium &Google Chrome 驱动程序以编程方式打开页面.在每个页面上都有一个动态生成的图像,我想下载它.目前,我正在等待页面完成加载,然后我获取图像 URL 并使用 System.Net.WebClient 下载它.
I'm using Selenium & Google Chrome Driver to open pages programatically. On each page there is a dynamically generated image which I'd like to download. At the moment, I'm waiting for the page to finish loading, then I grab the image URL and download it using System.Net.WebClient.
这很好,除了我下载了两次图像 - 一次在浏览器中,一次在 WebClient 中.问题是每张图片大约 15MB,下载两次加起来很快.
That works fine except I'm downloading the images twice - once in the browser, once with WebClient. The problem is that each image is roughly 15MB and downloading twice adds up quickly.
那么 - 是否可以直接从谷歌浏览器获取图像?
So - is it possible to grab the image straight from Google Chrome?
推荐答案
您可以使用 this 技术.它运行一个名为Block Image"的 Google Chrome 扩展程序.这样就不会使用 chrome 下载图像,只需使用其 URL & 正常下载图像即可.System.Net.WebClient.
You can block images from being downloaded in Google Chrome using this technique. It runs a Google Chrome extension called "Block Image". This way the image won't be downloaded using chrome, and it's just a matter of downloading the image as normal using its URL & System.Net.WebClient.
