+# Gopeed contributors guide
+
+Firstly, thank you for your interest in contributing to Gopeed. This guide will help you better
+participate in the development of Gopeed.
+
+## Branch description
+
+This project only has one main branch, namely the `main` branch. If you want to participate in the
+development of Gopeed, please fork this project first, and then develop in your fork project. After
+development is completed, submit a PR to this project and merge it into the `main` branch.
+
+## Local development
+
+It is recommended to develop and debug through the web. First, start the backend service, and start
+it by the command line `go run cmd/api/main.go`, the default port of the service is `9999`, and then
+start the front-end flutter project in `debug` mode to run.
+
+## Translation
+
+The internationalization files of Gopeed are located in the `ui/flutter/lib/i18n/langs` directory.
+You only need to add the corresponding language file in this directory.
+
+Please refer to `en_us.dart` for translation.
+words prefixed with `@` are not meant to be translated.
+
+## flutter development
+
+Don't forget to run`dart format ./ui/flutter`before you commit to keep your code in standard dart format
+
+Turn on build_runner watcher if you want to edit api/models:
+
+```
+flutter pub run build_runner watch
+```

+
+まず最初に、Gopeed への貢献に興味を持っていただきありがとうございます。このガイドは、あなたが Gopeed の
+開発に参加するための手助けとなるでしょう。
+
+## ブランチの説明
+
+このプロジェクトのメインブランチは `main` ブランチのみです。Gopeed の開発に参加したい場合は、
+まずこのプロジェクトをフォークし、フォークしたプロジェクトで開発を行ってください。開発が完了したら、
+このプロジェクトに PR を提出し、`main` ブランチにマージしてください。
+
+## ローカル開発
+
+開発およびデバッグはウェブ上で行うことを推奨する。まずバックエンドのサービスを起動し、
+コマンドライン `go run cmd/api/main.go` で起動する。サービスのデフォルトポートは `9999` で、
+次にフロントエンドの flutter プロジェクトを `debug` モードで起動して実行します。
+
+## 翻訳
+
+Gopeed の国際化ファイルは `ui/flutter/lib/i18n/langs` ディレクトリにあります。
+このディレクトリに対応する言語ファイルを追加するだけでよいです。
+
+翻訳については `en_us.dart` を参照してください。
+
+## flutter での開発
+
+コミットする前に `dart format ./ui/flutter` を実行し、コードを標準の dart フォーマットにしておくことを忘れないでください
+
+api/models を編集したい場合は build_runner watcher をオンにします:
+
+```
+flutter pub run build_runner watch
+```

+## 🚀 Giới thiệu
+
+Gopeed (tên đầy đủ Go Speed), một công cụ tải xuống tốc độ cao được phát triển bởi `Golang` + `Flutter`, hỗ trợ giao thức (HTTP, BitTorrent, Magnet, ED2K) và hỗ trợ tất cả các nền tảng. Ngoài các chức năng tải xuống cơ bản, Gopeed còn là một công cụ tải xuống có thể tùy chỉnh cao cho phép triển khai thêm tính năng thông qua việc tích hợp với [APIs](https://gopeed.com/docs/dev-api) hoặc cài đặt và phát triển các [tiện ích mở rộng](https://gopeed.com/docs/dev-extension).

+
+#### Desktop
+
+Trước tiên, bạn cần cấu hình môi trường theo tài liệu chính thức của [Tài liệu trang web máy tính để bàn Flutter](https://docs.flutter.dev/development/platform-integration/desktop), sau đó bạn cần đảm bảo môi trường cgo được thiết lập đúng. Để biết hướng dẫn chi tiết về cách thiết lập môi trường cgo, vui lòng tham khảo các tài liệu tương ứng có sẵn trực tuyến.

+# rpcprovider
+
+`rpcprovider` is the RPC-backed implementation of Gopeed's `webview.Provider` interface.
+
+It is intended for environments where WebView capability is owned by another process, most notably mobile hosts. This package does not implement a WebView itself. Instead, it translates the `pkg/download/engine/webview` page API into single-request `POST + JSON` calls sent to a local host-side RPC service.
+
+## When to use it
+
+Use `rpcprovider` for entrypoints such as `bind/mobile`, where the Go process cannot directly own a native WebView.
+
+Do not use it for desktop or `cmd/web` local WebView integration. Those entrypoints should use `internal/webview/goprovider` instead.
+
+## Configuration
+
+The provider is configured through `pkg/download/engine/webview.RPCConfig`:
+
+```go
+type RPCConfig struct {
+	Network string `json:"network"`
+	Address string `json:"address"`
+	Token   string `json:"token,omitempty"`
+}
+```
+
+Notes:
+
+- `Network` currently supports `tcp` and `unix`.
+- `Address` examples:
+  - `127.0.0.1:38765`
+  - `/path/to/webview.sock`
+- `Token` is optional. When set, the client sends `Authorization: Bearer <token>`.
+
+Example:
+
+```go
+provider := rpcprovider.New(webview.RPCConfig{
+	Network: "tcp",
+	Address: "127.0.0.1:38765",
+	Token:   "secret-token",
+})
+```
+
+## Transport
+
+- Endpoint: `POST /webview`
+- Content type: `application/json`
+- One request, one response
+- No `id` field yet
+- The envelope is intentionally close to JSON-RPC so it can evolve later without renaming the methods or reshaping the payloads
+
+Request example:
+
+```json
+{
+  "method": "page.execute",
+  "params": {
+    "pageId": "page-1",
+    "expression": "document.title",
+    "args": []
+  }
+}
+```
+
+Successful response:
+
+```json
+{
+  "result": {
+    "title": "Example"
+  },
+  "error": null
+}
+```
+
+Failure response:
+
+```json
+{
+  "result": null,
+  "error": {
+    "code": "PAGE_NOT_FOUND",
+    "message": "page not found"
+  }
+}
+```
+
+## Supported methods
+
+- `webview.isAvailable`
+- `page.open`
+- `page.addInitScript`
+- `page.goto`
+- `page.execute`
+- `page.getCookies`
+- `page.setCookie`
+- `page.deleteCookie`
+- `page.clearCookies`
+- `page.close`
+
+The canonical wire models for these methods are defined in:

+
+## Method semantics
+
+- `page.open`
+  - Creates a page session
+  - Returns `pageId`
+- `page.addInitScript`
+  - Registers a page initialization script
+- `page.goto`
+  - Goes to the target URL
+  - The server should return only after navigation completes or fails
+- `page.execute`
+  - Executes an expression or serialized function body
+  - The returned value must be JSON-serializable
+- `page.getCookies`
+  - Returns cookies from the underlying native WebView cookie store
+- `page.setCookie`
+  - Inserts or updates a cookie
+- `page.deleteCookie`
+  - Deletes a cookie using `name/domain/path`
+- `page.clearCookies`
+  - Clears the current cookie store
+- `page.close`
+  - Closes the page and releases related resources
+
+## Cookie model
+
+Cookies use `runtime/webview.Cookie`.
+
+Example payload:
+
+```json
+{
+  "name": "session",
+  "value": "abc",
+  "domain": ".example.com",
+  "path": "/",
+  "expires": "2026-03-26T12:00:00Z",
+  "secure": true,
+  "httpOnly": true
+}
+```
+
+Notes:
+
+- `expires` uses RFC3339 / RFC3339Nano string form.
+- If the host platform supports a full native cookie store, it should return fields such as `httpOnly` and `secure`.
+- `setCookie -> goto` is a valid pattern for preloading authenticated session state.
+
+## Error codes
+
+The current error code set is defined in `pkg/download/engine/webview/rpc.go`:
+
+- `INVALID_REQUEST`
+- `UNKNOWN_METHOD`
+- `UNAVAILABLE`
+- `BROWSER_NOT_FOUND`
+- `PAGE_NOT_FOUND`
+- `NAVIGATION_FAILED`
+- `EVALUATION_FAILED`
+- `TIMEOUT`
+- `INTERNAL_ERROR`
+
+`BROWSER_NOT_FOUND` is a historical leftover from an earlier shape of the protocol. The current protocol no longer has a separate browser model, so this can be cleaned up later if the protocol is tightened further.
+
+## Current protocol boundary
+
+This protocol is intentionally limited:
+
+- Single-direction request/response only
+- Not REST-style resource routing
+- No bidirectional events
+- No streaming event subscriptions
+- No host-initiated push channel
+
+If the protocol needs to evolve toward full JSON-RPC later, the intended migration path is to keep the existing `method/params/result/error` structure and add:
+
+- `id`
+- notifications
+- a bidirectional transport model
+
+## Host implementation guidance
+
+A host implementation should usually:
+
+- Listen on a local `tcp` address or `unix socket`
+- Expose `POST /webview`
+- Validate the bearer token if configured
+- Maintain `pageId -> native webview/session`
+- Own page lifecycle, cleanup, and timeout handling
+
+With that split, Gopeed stays a pure RPC client and does not need to know how the host's native WebView is implemented.
