rust实战：用rust写一个cli小工具（续）3、参数验证参数验证我们需要实现两个点，第一个是url的合法性验证，第二个就是post的请求的body部分验证。对于第一部分的url验证，十分简单，先上代码#[derive(Parser, Debug)]structGet {//clap允许为每个解析出来的值添加自定义的解析函数/// http请求的url#[clap(par...
rustuse hyper::{Client, Uri};use tokio::io::{self, AsyncWriteExt as _};async fn fetch_url(url:&str)-> io::Result<String>{ let client = Client::new(); let uri = url.parse::<Uri>().unwrap(); let response = client.get(uri).await?; let mut body = String::new(...
从提供的 URL 字符串中提取主机和scheme等信息: use url::{Url, Host, ParseError}; fn main() -> Result<(), ParseError> { let string ="https://jdon.com"; let url = Url::parse(string)?; let scheme = url.scheme(); let host = url.host(); println!("Scheme: {}", scheme); prin...
rustuse reqwest::Error;use scraper::{Html, Selector};#[tokio::main]async fn main()-> Result<(), Error>{ let url =";; let body = reqwest::get(url).await?.text().await?; let document = Html::parse_document(&body); let selector = Selector::parse("div#content h1"...
Rust是一种系统级编程语言,具有内存安全、并发性和高性能的特点。它适用于各种应用场景,包括云计算领域。在Rust中,删除URL中特定的GET参数可以通过以下步骤实现: 解析URL:使用Rust的url库,可以方便地解析URL。通过将URL字符串传递给url::Url::parse函数,可以将URL解析为url::Url类型的对象。
rustuse reqwest::header::{USER_AGENT, HeaderMap};use reqwest::Client;use scraper::{Html, Selector};use std::fs::File;use std::io::{BufWriter, Write};fn main()-> std::io::Result<()>{ let url =";; let html = get_html(url)?; let data = parse_html(&html); sa...
("{}", page); let response = client.get(&url).send()?; let html = response.text()?; let document = Html::parse_document(&html); let title_selector = Selector::parse("h2.title").unwrap(); let content_selector = Selector::parse("div.content").unwrap(); for...
解析出key value后,用&str指向URL中的位置,然后用Cow封装它。 当解析出来的内容不能直接使用,需要加decode时,可以用Cow封装。(不能直接使用是指被转义过后的?) 解析url: use std::borrow::Cow; use url::Url; fn main() { let url = Url::parse("https://tyr.com/rust?page=1024&sort=desc&extra=...
ParseError + } + } // main.rs mod error; use chrono::NaiveDate; use error::MyCustomError; use std::collections::HashMap; fn main() { // skipped, will get back later } fn get_current_date() -> Result<String, MyCustomError> { let url = "https://postman-...
baseUrl: Uri.parse("http://localhost:5800"), ); try { final data1 = await api.helloGet(name: "Olly"); setState(() { _text = data1.body!; // << Is string, or can be complex object. }); } catch (e) { print(e); ...
