Small library to fetch info about a web page: title, description, language, HTTP info, RSS feeds, Opengraph, Schema.org, and more
extern crate webpage;
use webpage::{Webpage, WebpageOptions};
// ...
info = Webpage::from_url("http://www.rust-lang.org/en-US/", WebpageOptions::default())
.expect("Could not read from URL");
// the HTTP transfer info
let http = info.http;
assert_eq!(http.ip, "54.192.129.71".to_string());
assert!(http.headers[0].starts_with("HTTP"));
assert!(http.body.starts_with("<!DOCTYPE html>"));
assert_eq!(http.url, "https://www.rust-lang.org/en-US/".to_string()); // followed redirects (HTTPS)
assert_eq!(http.content_type, "text/html".to_string());
// the parsed HTML info
let html = info.html;
assert_eq!(html.title, Some("The Rust Programming Language".to_string()));
assert_eq!(html.description, Some("A systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.".to_string()));
assert_eq!(html.opengraph.og_type, "website".to_string());You can also get HTML info about local data:
use webpage::HTML;
let html = HTML::from_file("index.html", None);
// or let html = HTML::from_string(input, None);pub struct Webpage {
pub http: HTTP, // info about the HTTP transfer
pub html: HTML, // info from the parsed HTML doc
}
pub struct HTTP {
pub ip: String,
pub transfer_time: Duration,
pub redirect_count: u32,
pub content_type: String,
pub response_code: u32,
pub headers: Vec<String>, // raw headers from final request
pub url: String, // effective url
pub body: String,
}
pub struct HTML {
pub title: Option<String>,
pub description: Option<String>,
pub url: Option<String>, // canonical url
pub feed: Option<String>, // RSS feed typically
pub language: Option<String>, // as specified, not detected
pub text_content: String, // all tags stripped from body
pub meta: HashMap<String, String>, // flattened down list of meta properties
pub opengraph: Opengraph,
pub schema_org: Vec<SchemaOrg>,
}
pub struct Opengraph {
pub og_type: String,
pub properties: HashMap<String, String>,
pub images: Vec<Object>,
pub videos: Vec<Object>,
pub audios: Vec<Object>,
}
// Facebook's Opengraph structured data
pub struct OpengraphObject {
pub url: String,
pub properties: HashMap<String, String>,
}
// Google's schema.org structured data
pub struct SchemaOrg {
pub schema_type: String,
pub value: serde_json::Value,
}The following configurations are available:
pub struct WebpageOptions {
allow_insecure: false,
follow_location: true,
max_redirections: 5,
timeout: Duration::from_secs(10),
useragent: "Webpage - Rust crate - https://crates.io/crates/webpage".to_string(),
}
// usage
let options = WebpageOptions { allow_insecure: true, ..Default::default() };
let info = Webpage::from_url(&url, options).expect("Halp, could not fetch");
