+# EmblemScanner 微信小程序扫码验证模块
+
+## Release notes
+- Version 1.0.1: initial release
+- Version 1.1.0: sub package support
+
+
+## 概述
+
+EmblemScanner 是一个专为微信小程序设计的二维码扫描验证模块，集成了先进的 AI 图像识别技术和二维码检测算法，能够快速准确地识别和验证二维码。
+
+## 集成方式和接口
+
+### 调用参数
+
+| 参数 | 说明 | 示例值 |
+|------|------|--------|
+| return_page | 扫描完成后跳转的页面路径 | `/pages/scan_result/scan_result` |
+
+### 扫描结果
+
+扫描成功后，模块会跳转到指定的 return_page，携带以下参数：
+- `ok=1` - 扫描成功
+- `qr_code` - 二维码内容
+- `serial_code` - 验证序列号（如有）
+
+扫描失败时：
+- `ok=0` - 扫描失败
+
+### 依赖要求
+
+- 相机权限
+- 网络访问权限（连接 themblem.com API等）
+
+## 使用步骤
+
+### 1. 项目准备
+创建 JS 版小程序项目。
+
+### 2. 文件部署
+解压 emblemscanner 代码到小程序项目目录。
+

+└── worker/              # Worker 线程
+```
+
+### 3. 项目配置
+
+在 `app.json` 中添加页面和 worker 配置：
+
+```json
+{
+  "pages": [
+    "pages/index/index",
+    "pages/emblemscanner/emblemscanner",
+    "pages/logs/logs"
+  ],
+  "workers": "pages/emblemscanner/worker"
+}
+```
+
+### 4. 域名配置
+
+参考[微信小程序网络配置指南](https://developers.weixin.qq.com/miniprogram/dev/framework/ability/network.html)，在小程序后台配置合法域名：
+
+- `themblem.com`
+
+### 5. 扫码调用
+
+#### 跳转到扫码页面：
+```javascript
+navigateToScanner() {
+  wx.navigateTo({
+    url: '/pages/emblemscanner/emblemscanner?return_page=/pages/scan_result/scan_result'
+  })
+}
+```
+
+#### 处理扫码结果：
+```javascript
+onLoad(options) {
+  var verify_ok = options['ok'];        // ok == 1表示验证通过
+  var qr_code = options['qr_code'];     // 二维码内容
+  var serial_code = options['serial_code']; // 序列码
+
+  this.setData({
+    verify_ok,
+    qr_code,
+    serial_code,
+  })
+}
+```
