* fix(http): decode response header values as ISO-8859-1

Response header values were decoded with String::from_utf8 before being
sent over IPC. Raw UTF-8 bytes produced JS strings with code points
above 255, which new Headers() rejects as invalid ByteStrings
("Type error" on WebKit), and bytes that were not valid UTF-8 failed
the fetch outright. Decode as ISO-8859-1 instead so every byte maps to a
char 0-255, matching what browsers expose for the same response.

Fixes #2898

* fix(http): add tests for ISO-8859-1 response header decoding

Cover the #2898 Content-Disposition case and non-UTF-8 header bytes on
the same conversion fetch_send uses, so a revert to UTF-8 fails the suite.

* request headers, e2e test

plugin-http

Access the HTTP client written in Rust.

Platform Supported
Linux ✓

macOS ✓
Android ✓

Install

This plugin requires a Rust version of at least 1.90

There are three general methods of installation that we can recommend.

  1. Use crates.io and npm (easiest, and requires you to trust that our publishing pipeline worked)
  2. Pull sources directly from Github using git tags / revision hashes (most secure)
  3. Git submodule install this repo in your tauri project and then use file protocol to ingest the source (most secure, but inconvenient to use)

Install the Core plugin by adding the following to your Cargo.toml file:

src-tauri/Cargo.toml

[dependencies]
tauri-plugin-http = "2.0.0"
# alternatively with Git:
tauri-plugin-http = { git = "https://github.com/tauri-apps/plugins-workspace", branch = "v2" }

You can install the JavaScript Guest bindings using your preferred JavaScript package manager:

pnpm add @tauri-apps/plugin-http
# or
npm add @tauri-apps/plugin-http
# or
yarn add @tauri-apps/plugin-http

Usage

First you need to register the core plugin with Tauri:

src-tauri/src/lib.rs

fn main() {
    tauri::Builder::default()
        .plugin(tauri_plugin_http::init())
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

Afterwards all the plugin's APIs are available through the JavaScript guest bindings:

import { fetch } from '@tauri-apps/plugin-http'
const response = await fetch('http://localhost:3003/users/2', {
  method: 'GET',
  connectTimeout: 30
})
