快速開始

於Line Develop Console 取得 Channel Secret 及 Access Token

https://developers.line.biz/zh-hant/

• 申請一個Provider
• 申請一個Channel (一個Provider可以有多個Channel)
• 於Channel取得 Channel Secret 及 Access Token
• Use webhook 啟用
• Auto-reply messages 關閉
• 設定 Webhook URL (需為https)

Startup.cs 新增 AddLineBotSDK

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllers();
    services.AddLineBotSDK(Configuration);
}

新增一個 Web Api Controller

[Route("api/[controller]")]
[ApiController]
public class LineController : ControllerBase
{
    private readonly ILineMessageUtility lineMessageUtility;
    public LineController(ILineMessageUtility _lineMessageUtility)
    {
        lineMessageUtility = _lineMessageUtility;
    }

    [HttpPost]
    [LineVerifySignature]
    public async Task<IActionResult> Post(WebhookEvent request)
    {
        var app = new LineBotSampleApp(lineMessageUtility);
        await app.RunAsync(request.events);
        return Ok();
    }
}

繼承 LineBotApp，可針對不同事件 override 處理

public class LineBotSampleApp : LineBotApp
{
    private readonly ILineMessageUtility lineMessageUtility;
    public LineBotSampleApp(ILineMessageUtility _lineMessageUtility) : base(_lineMessageUtility)
    {
        lineMessageUtility = _lineMessageUtility;
    }

    protected override async Task OnMessageAsync(LineEvent ev)
    {
        await lineMessageUtility.ReplyMessageAsync(ev.replyToken, $"You Said:{ev.message.Text}");
    }
}

完成第一個 Echo Bot

)

appsettings.json 增加token

"LineSetting": {
    "ChannelSecret": "<Your Line Channel Secret>",
    "ChannelAccessToken": "<Your Line Channel Access Token>"
}
