Requirements

This library requires stable/beta Rust.

Installation

[dependencies]
line-bot-sdk-rust = "1.0.0"

If you use rocket support.

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

If you use actix_web support.

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

Configuration

extern crate line_bot_sdk_rust as line;
use line::messaging_api::apis::configuration::Configuration;
use std::env;

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

    let mut conf = Configuration::default();
    conf.bearer_access_token = Some(access_token.to_string());
}

How to use

The LINE Messaging API uses the JSON data format.

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
        }
    }
}
