Crate spectreq 

Spectre - HTTP client with browser impersonation

This library provides an HTTP client that mimics real browser fingerprints for anti-bot detection evasion.

Features

• Browser Profiles: Pre-configured profiles for Chrome, Firefox, Safari, and Edge
• TLS Fingerprinting: JA4 TLS fingerprint support with customizable cipher suites
• HTTP/2 Settings: Browser-specific HTTP/2 parameters
• TCP Configuration: Socket options for fingerprint accuracy
• Client Hints: Sec-CH-UA-* header generation
• Fetch Headers: Sec-Fetch-* header generation
• HTTP Caching: In-memory cache with ETag and Last-Modified validation
• Cookie Management: Automatic cookie storage and inclusion in requests
• Proxy Support: HTTP CONNECT and SOCKS5 proxy support
• Certificate Pinning: SPKI hash-based certificate verification
• Session Persistence: Save/load sessions with cookies and TLS tickets

Quick Start

use spectreq::{Client, Profile};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create client with Chrome 143 profile
    let client = Client::new(Profile::chrome_143_windows()).await?;

    // Make a GET request
    let response = client.get("https://httpbin.org/get").await?;
    println!("Status: {}", response.status);
    println!("Body: {}", response.text()?);

    Ok(())
}
