二、网络请求 在进行图片抓取之前，我们需要先进行网络请求，获取到需要抓取的网页内容。为了实现这个功能，我们可以使用第三方库reqwest。下面是一个示例代码：a6ae9f325bc628e1553e268cf46ea1d0::blocking::Client;use reqwest::header::{HeaderMap, USER_AGENT};fn fetch(url:&str)-> String { let client ...

使用reqwest::Client来创建一个HTTP客户端实例。这个实例可以用来发送多个请求,并且会重用底层的TCP连接,从而提高性能。 rust use reqwest::Client; let client = Client::new(); 构建HTTP请求(指定URL、HTTP方法、请求头等) 使用Client实例的request方法来构建一个HTTP请求。你需要指定HTTP方法(如GET、POST等)、...

常见的http请求头有User-Agent, 用于简单的反爬以及反反爬。 reqwest同时支持两种设定请求头的方式,方法如下: use std::collections::HashMap;use reqwest::Result;use reqwest::header;#[tokio::main]async fnmain()->Result<()>{let url="https://youerning.top";let client=reqwest::Client::new();let...
