From fe51cd504fac4b49904942a75839a7a5aa73f146 Mon Sep 17 00:00:00 2001 From: ex-takashima Date: Wed, 8 Apr 2026 00:38:55 +0900 Subject: [PATCH 001/114] refactor(line): use official LINE Bot SDK v8 Replace hand-rolled HTTP/HMAC/JSON code (~270 lines) with the official line-bot-sdk-go v8, reducing maintenance burden and eliminating potential bugs in signature verification, request construction, and response parsing. This continues the work started in #500 by @xiaket, addressing all review feedback and rebasing onto current main. Changes: - Replace bytes/crypto/json/io imports with line-bot-sdk-go/v8 - Use webhook.ParseRequest for body reading + signature verification - Use messaging_api.MessagingApiAPI for ReplyMessage/PushMessage/ShowLoadingAnimation/GetBotInfo - Type-switch on webhook.MessageEvent message types (TextMessageContent, ImageMessageContent, etc.) instead of JSON unmarshalling - Type-switch on webhook.SourceInterface (UserSource/GroupSource/RoomSource) - Type-switch on webhook.Mentionee (UserMentionee/AllMentionee) Review feedback addressed (from #500): - Use WithContext(ctx) on all SDK calls to preserve cancellation/timeout - Fix variable shadowing of isMentioned (declared at function scope) - Remove reflect-based message ID extraction (use type switch + msg.Id) - Use mentionee.IsSelf for cleaner bot mention detection - Preserve body size security check via http.MaxBytesReader before webhook.ParseRequest (compatible with #1413) All existing tests pass without modification. --- go.mod | 1 + go.sum | 2 + pkg/channels/line/line.go | 466 ++++++++++++++------------------------ 3 files changed, 174 insertions(+), 295 deletions(-) diff --git a/go.mod b/go.mod index a9f4bb7cb..2cd09df0f 100644 --- a/go.mod +++ b/go.mod @@ -24,6 +24,7 @@ require ( github.com/gorilla/websocket v1.5.3 github.com/h2non/filetype v1.1.3 github.com/larksuite/oapi-sdk-go/v3 v3.5.3 + github.com/line/line-bot-sdk-go/v8 v8.19.0 github.com/mdp/qrterminal/v3 v3.2.1 github.com/minio/selfupdate v0.6.0 github.com/modelcontextprotocol/go-sdk v1.4.1 diff --git a/go.sum b/go.sum index 765a3211a..fe33d992b 100644 --- a/go.sum +++ b/go.sum @@ -175,6 +175,8 @@ github.com/kr/text v0.2.0 h1:5Nx0Ya0ZqY2ygV366QzturHI13Jq95ApcVaJBhpS+AY= github.com/kr/text v0.2.0/go.mod h1:eLer722TekiGuMkidMxC/pM04lWEeraHUUmBw8l2grE= github.com/larksuite/oapi-sdk-go/v3 v3.5.3 h1:xvf8Dv29kBXC5/DNDCLhHkAFW8l/0LlQJimO5Zn+JUk= github.com/larksuite/oapi-sdk-go/v3 v3.5.3/go.mod h1:ZEplY+kwuIrj/nqw5uSCINNATcH3KdxSN7y+UxYY5fI= +github.com/line/line-bot-sdk-go/v8 v8.19.0 h1:5FD/1SprRZ8Y0FiUI6syYiBewOs0ak2tuUBMYN0wzE4= +github.com/line/line-bot-sdk-go/v8 v8.19.0/go.mod h1:AeSRUuu7WGgveGDJb6DyKyFUOst2UB2aF6LO2cQeuXs= github.com/lucasb-eyer/go-colorful v1.3.0 h1:2/yBRLdWBZKrf7gB40FoiKfAWYQ0lqNcbuQwVHXptag= github.com/lucasb-eyer/go-colorful v1.3.0/go.mod h1:R4dSotOR9KMtayYi1e77YzuveK+i7ruzyGqttikkLy0= github.com/mattn/go-colorable v0.1.14 h1:9A9LHSqF/7dyVVX6g0U9cwm9pG3kP9gSzcuIPHPsaIE= diff --git a/pkg/channels/line/line.go b/pkg/channels/line/line.go index 230983935..3de2397be 100644 --- a/pkg/channels/line/line.go +++ b/pkg/channels/line/line.go @@ -1,19 +1,17 @@ package line import ( -
