+This plugin integrates Tencent Cloud Object Storage (COS) with the [Egg.js](https://eggjs.org/en/tutorials/index.html) framework, a Node.js framework developed by Alibaba Group. 
+It supports two methods for file uploads: 
+- file mode：its better for small file is temporarily stored on the server during processing;
+- stream mode: for large files, server friendly;
 
 Initially, I attempted to contribute the stream mode functionality to another project, but did not receive a response from the owner. Therefore, I decided to release this plugin to the community.

+腾讯云cos存储在Egg.js框架插件 Tencent COS(Cloud Object Storage) Egg.js 插件
+
+此插件将腾讯云对象存储（COS）集成到由阿里巴巴集团开发的 [Egg.js](https://eggjs.org/zh-cn/tutorials/index.html) 框架中。它支持两种文件上传方式：
+- 文件块模式：适用于小文件，会占用服务器的空间
+- 文件流模式：适合大文件，不会占用自己的后端服务器空间,服务器友好
+
+最初，我尝试将流模式功能贡献给另一个项目，但未收到项目所有者的回复。因此，我决定将此插件发布给社区。
+
+## 安装
+
+```bash
+npm install @onewalker/egg-cos
+```
+
+## 配置
+
+```js
+// {app_root}/config/plugin.js
+exports.cos = {
+  enable: true,
+  package: '@onewalker/egg-cos'
+};
+```
+
+```js
+// {app_root}/config/config.default.js
+exports.cos = {
+  client: {
+    SecretId: '',
+    SecretKey: '',
+    Bucket: '',
+    Region: ''
+  }
+};
+```
+
+在 egg agent 中初始化，默认值为 `false`：
+
+```js
+exports.cos = {
+  useAgent: true
+};
+```
+
+## 使用
+
+你可以在 `app` 或 `ctx` 上获取腾讯云 cos 实例。
+// 在控制器中上传文件
+
+- 文件模式：文件在处理过程中会暂时存储在服务器中；
+
+```js
+const path = require('path');
+const Controller = require('egg').Controller;
+
+module.exports = class extends Controller {
+  async upload() {
+    const ctx = this.ctx;
+    // 请启用 `egg-multipart` 的 `file` 模式。
+    const file = ctx.request.files[0];
+    const name = 'egg-cos/' + path.basename(file.filename);
+    let result;
+    try {
+      result = await ctx.cos.put(name, file.filepath);
+    } finally {
+      // 需要删除临时文件
+      await ctx.cleanupRequestFiles();
+    }
+
+    if (result) {
+      ctx.logger.info('cos response:\n', result);
+      ctx.body = {
+        url: `https://${result.Location}`
+      };
+    } else {
+      ctx.body = '请选择一个文件上传！';
+    }
+  }
+};
+```
+- 流模式上传：文件直接传输到云服务器，不经过你的服务器；
+
+```js
+const Controller = require('egg').Controller;
+const sendToWormhole = require('stream-wormhole');
+async upload() {
+  const ctx = this.ctx;
+  const parts = ctx.multipart();
+  let part, results = [];
+  while ((part = await parts()) != null) {
+    if (part.length) {
+      // 这是 part 流的内容
+      console.log('field: ' + part[0]);
+      console.log('value: ' + part[1]);
+      console.log('valueTruncated: ' + part[2]);
+      console.log('fieldnameTruncated: ' + part[3]);
+    } else {
+      if (!part.filename) {
+        return;
+      }
+      console.log('field: ' + part.fieldname);
+      console.log('filename: ' + part.filename);
+      console.log('encoding: ' + part.encoding);
+      console.log('mime: ' + part.mime);
+      console.log("part", part.stream, typeof part);
+      // 文件处理，将文件上传到腾讯云服务器
+      let result;
+      let path = await ctx.helper.MD5encode(String(Date.now()));
+      let typeArray = part.mime.split('/');
+      let type = typeArray[typeArray.length - 1];
+      let name = 'ysxbdms/projects/' + path + `.${type}`; // 上传链接
+      try {
+        result = await ctx.cos.putStream(name, part);
+      } catch (err) {
+        await sendToWormhole(part);
+        throw err;
+      }
+      console.log(result);
+      results.push(result);
+    }
+  }
+  console.log('表单解析完成！');
+  ctx.body = results;
+};
+```
