+# android-gateway（安卓短信网关端）
+
+## 使用方式（Android Studio 导入）
+
+由于仓库里无法直接提供 `gradle-wrapper.jar` 这类二进制文件，你需要在 Android Studio 里先创建一个项目，再把本目录里的源码/配置拷贝进去。
+
+1. Android Studio：创建新项目
+   - Template：`Empty Activity`
+   - Kotlin：勾选
+   - Package name：`com.yunzer.sms`（建议与本项目一致）
+2. 把本目录 `app/src/main/...` 下的内容复制到你新建项目对应位置（覆盖同名文件）
+3. 把本目录根目录下的 `build.gradle` / `settings.gradle` / `app/build.gradle` 复制到对应位置（如需）
+
+## 配置说明（运行前）
+
+首次进入 App 会让你填写：
+
+- `backendUrl`：例如 `http://192.168.1.10:3000`
+- `apiKey`：后端 `.env` 里的 `SMS_GATEWAY_API_KEY`
+- （不再需要 `deviceId`：由后端根据 `apiKey` 自动归属任务/短信）
+
+保存后 App 会：
+
+- 启动前台服务轮询后端下发发送任务
+- 注册系统短信接收广播，上报短信内容并解析验证码
+
+你也可以点击 `检测心跳` 按钮，用于手动验证 App 与后端的网络/鉴权通断。
+
+## 注意事项
+
+- 需要运行时授权：`接收短信`、`发送短信`
+- 安卓 13+ 还需要授权：`通知`（用于前台服务）
+- 该端用于你自己的合法业务场景，避免违规批量操作

+# 短信网关后端（backend）
+
+## 目标
+
+为安卓短信网关端提供：
+
+- 接收短信上报（`/api/v1/sms/inbound`）
+- 为指定设备下发发送任务（`/api/v1/device/tasks`）
+- 接收发送结果回传（`/api/v1/sms/outbound/result`）
+- 业务系统入队发送任务（`/api/v1/business/outbound-tasks`）
+
+使用 SQLite（单文件数据库）便于自部署。
+
+## 环境准备
+
+1. 安装 Node.js 18+
+2. 进入 `backend` 目录
+3. 复制 `.env.example` 为 `.env` 并修改 `SMS_GATEWAY_API_KEY`
+
+## 启动
+
+```bash
+cd backend
+npm i
+npm start
+```
+
+默认监听：`http://localhost:3000`
+
+## 鉴权
+
+所有接口都要求请求头：`X-Api-Key: <SMS_GATEWAY_API_KEY>`
+
+## API 说明
+
+1. 入站上报
+   - `POST /api/v1/sms/inbound`
+   - body 示例：
+     - `sender`：字符串（短号码/发送方）
+     - `content`：短信文本
+     - `receivedAt`：毫秒时间戳（可选；不传则由服务端补齐）
+     - `parsedCode`：解析后的验证码（可空）
+     - `parseStatus`：字符串（如 `matched`/`unmatched`/`error`）
+     - `rawPduHash`：字符串（用于去重，可选）
+
+2. 设备拉取任务
+   - `GET /api/v1/device/tasks?limit=5`
+   - 返回：`{ tasks: [...] }`
+
+3. 设备回传任务结果
+   - `POST /api/v1/sms/outbound/result`
+   - body 示例：
+     - `taskId`
+     - `status`：`success`/`failed`
+     - `error`：失败原因（可选）
+
+4. 业务系统入队发送任务
+   - `POST /api/v1/business/outbound-tasks`
+   - body 示例：
+     - `phone`
+     - `content`
+   - 返回：`{ taskId }`
+
+5. 业务系统读取入站验证码（可选但建议）
+   - `GET /api/v1/business/inbound-sms?since=0&limit=20&onlyMatched=false`
+   - 说明：
+     - `since`：毫秒时间戳，返回该时间之后的短信
+     - `onlyMatched=true`：只返回 `parseStatus=matched` 的验证码
+   - 返回：`{ inbounds: [...] }`
+

+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+
+## Usage
+
+```javascript
+var flatten = require('array-flatten')

+flatten([1, [2, [3, [4, [5], 6], 7], 8], 9])
+//=> [1, 2, 3, 4, 5, 6, 7, 8, 9]
+
+flatten([1, [2, [3, [4, [5], 6], 7], 8], 9], 2)
+//=> [1, 2, 3, [4, [5], 6], 7, 8, 9]
+
+(function () {
+  flatten(arguments) //=> [1, 2, 3]

+base64-js
+=========
+
+`base64-js` does basic base64 encoding/decoding in pure JS.
+
+[![build status](https://secure.travis-ci.org/beatgammit/base64-js.png)](http://travis-ci.org/beatgammit/base64-js)
+
+Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.
+
+Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.
+
+## install
+
+With [npm](https://npmjs.org) do:
+
+`npm install base64-js` and `var base64js = require('base64-js')`
+
+For use in web browsers do:
+
+`<script src="base64js.min.js"></script>`
+
+[Get supported base64-js with the Tidelift Subscription](https://tidelift.com/subscription/pkg/npm-base64-js?utm_source=npm-base64-js&utm_medium=referral&utm_campaign=readme)
+
+## methods
+
+`base64js` has three exposed functions, `byteLength`, `toByteArray` and `fromByteArray`, which both take a single argument.
+
+* `byteLength` - Takes a base64 string and returns length of byte array
+* `toByteArray` - Takes a base64 string and returns a byte array
+* `fromByteArray` - Takes a byte array and returns a base64 string
