+# DeepLX Serverless
+
+DeepLX 免费翻译API**腾讯云函数部署版**，与[原项目DeepLX](https://github.com/OwO-Network/DeepLX)的区别在于**利用了云函数的请求IP不固定的特性，极大程度上避免了`429`请求太频繁报错**
+
+感谢原项目[OwO-Network/DeepLX](https://github.com/OwO-Network/DeepLX)提供的灵感，这是本项目的坚实基础
+
+## Usage | 用法
+
+### Prerequisites | 你需要准备什么
+
+- 一台电脑或平板
+- 一个腾讯旗下的账号或者手机号
+
+### Deploy | 部署
+
+在 [https://cloud.tencent.com/](https://cloud.tencent.com/) 注册账号
+
+进入云函数控制台：[https://console.cloud.tencent.com/scf/list](https://console.cloud.tencent.com/scf/list)
+
+依次点击【新建】->【从头开始】，然后按照以下配置，**没写出来的就不用管，使用默认设置**
+
+- 函数类型：Web函数
+- 函数名称：deeplx（名字随便取）
+- 地域：任意（国内也可直连）
+- 运行环境：Nodejs 16.13（或者更高的版本）
+- 高级配置:
+    - 内存：64M
+    - 执行超时时间：60 秒
+    - 请求多并发：5 并发（个人体验下来，2个都行）
+- 日志配置 -> 日志投递：启用（可以选择不开，开的话一个月应该几分钱）
+- 函数代码：本地上传zip包（[点我下载 ZIP 包](https://github.com/LegendLeo/deeplx-serverless/releases/download/v1.0.0/dist.zip)）
+- 触发器配置（这里可能要创建一个新的触发器）：
+    - 默认触发器
+    - 触发别名/版本：默认流量
+    - 请求方法：ANY
+    - 发布环境：发布
+    - 鉴权方法：免鉴权
+
+此时已部署完成，可以点击“完成”按钮，进入【函数管理】，点击【函数代码】，往下拉，找到【访问路径】并复制后续使用
+
+
+### How to use | 如何使用
+
+建议搭配浏览器插件沉浸式翻译一同使用，使用的时候需要把访问路径里的 `/release` 部分替换为翻译路径`translate`
+
+例如：`https://service-aaaaa.gz.apigw.tencentcs.com/release/` 改为：`https://service-aaaaa.gz.apigw.tencentcs.com/translate`
+
+请求示例：
+
+``` bash
+curl --location 'https://service-aaaaa.gz.apigw.tencentcs.com/translate' \
+--header 'Content-Type: application/json' \
+--data '{
+    "text": "你好，世界",
+    "source_lang": "zh",
+    "target_lang": "en"
+}'
+```
+
+响应示例：
+
+``` json
+{
+  "code": 200,
+  "message": "success",
+  "data": "Hello, world.",
+  "source_lang": "zh",
+  "target_lang": "en",
+  "alternatives": ["Hello, World.", "Hello, world!", "Hi, world."]
+}
+```
+
+#### 沉浸式翻译设置
+
+1. 在浏览器上安装最新的 [沉浸式翻译](https://github.com/immersive-translate/immersive-translate/releases)。
+2. 点击左下角的 "开发者设置"。启用测试版实验功能。
+3. 翻译服务选中 `DeepLX(beta)`
+3. 设置 URL 为刚才获取的访问路径（需带translate）。

+
+## 自托管
+
+尽管本项目是专为 serverless 适配的方案，但是也能使用自己提供服务器进行部署
+
+``` bash
+git clone https://github.com/LegendLeo/deeplx-serverless
+cd deeplx-serverless
+npm install
+npm run start
+```
