LINE Messaging API SDK for Rust

Introduction

The LINE Messaging API SDK for Rust makes it easy to develop bots using LINE Messaging API, and you can create a sample bot within minutes.

Documentation

See the official API documentation for more information.

Requirements

This library requires stable/beta Rust.

Installation

$ cargo add line-bot-sdk-rust

Web framework support

Extract x-line-signature from the request header.

Use rocket framework

[dependencies.line-bot-sdk-rust]
version = "1.0.0"
features = ["rocket_support"]

use line_bot_sdk_rust::support::rocket::Signature;
use rocket::{http::Status, post};

#[post("/callback", data = "<body>")]
async fn world(signature: Signature, body: String) -> (Status, &'static str) {
    ...
}

Use actix_web framework

[dependencies.line-bot-sdk-rust]
version = "1.0.0"
features = ["actix_support"]

use actix_web::{post, web, Error, HttpResponse};
use line_bot_sdk_rust::support::actix::Signature;

#[post("/callback")]
async fn callback(signature: Signature, bytes: web::Bytes) -> Result<HttpResponse, Error> {
    ...
}

Configuration

use line_bot_sdk_rust::client::LINE;
use std::env;

fn main() {
    let access_token: &str =
        &env::var("LINE_CHANNEL_ACCESS_TOKEN").expect("Failed to get LINE_CHANNEL_ACCESS_TOKEN");

    let line = LINE::new(access_token.to_string());
}

How to use

The LINE Messaging API uses the JSON data format.

Example. Parse body (&str) into Result<CallbackRequest, serde_json::Error>.

let request: Result<CallbackRequest, serde_json::Error> = serde_json::from_str(body);

match request {
    Err(err) => {
        // error handling
    },
    Ok(req) => {
        for e in req.events {
            // Processing for various events
        }
    }
}
