Register with [coze.com](https://www.coze.com) or [coze.cn](https://www.coze.cn)and obtain your API token 15 | ![cozeapitoken](pictures/token.png) 16 | 17 | 2. Create your bot and publish it to the API 18 | ![cozeapi](pictures/api.png) 19 | 20 | 3. Obtain the bot's ID,the number after the bot parameter, and configure it as an environment variable 21 | ```bash 22 | https://www.coze.com/space/73428668341****/bot/73428668***** 23 | ``` 24 | 25 | ## Deployment 26 | ### Zeabur 27 | [![Deploy on Zeabur](https://zeabur.com/button.svg)](https://zeabur.com/templates/BZ515Z?referralCode=fatwang2) 28 | 29 | ### Vercel 30 | [![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https://github.com/fatwang2/coze2openai&env=BOT_ID&envDescription=COZE_BOT_ID) 31 | 32 | **Note:** Vercel's serverless functions have a 10-second timeout limit. 33 | 34 | ### Railway 35 | [![Deploy on Railway](https://railway.app/button.svg)](https://railway.app/template/yM5tQL?referralCode=mDim7U) 36 | 37 | ### Docker Deployment 38 | 39 | 1. Ensure Docker and Docker Compose are installed on your machine. 40 | 41 | 2. Clone the project repository: 42 | ``` 43 | git clone https://github.com/your-username/coze2openai.git 44 | cd coze2openai 45 | ``` 46 | 47 | 3. Create and configure the `.env` file: 48 | ``` 49 | cp .env.template .env 50 | ``` 51 | Edit the `.env` file and fill in your BOT_ID and other necessary configurations. 52 | 53 | 4. Build and start the Docker container: 54 | ``` 55 | docker-compose up -d 56 | ``` 57 | 58 | 5. Visit `http://localhost:3000` to confirm that the service is running correctly. 59 | 60 | To stop the service, run: 61 | ``` 62 | docker-compose down 63 | ``` 64 | 65 | Note: The Dockerfile uses Taobao NPM mirror, you can comment out or replace other different mirror: 66 | ```Dockerfile 67 | ENV NPM_CONFIG_REGISTRY=https://registry.npmmirror.com/ 68 | ENV PNPM_REGISTRY=https://registry.npmmirror.com/ 69 | ``` 70 | 71 | ### Local Deployment 72 | 1. Set the environment variable on `.env` file 73 | ```bash 74 | BOT_ID=xxxx 75 | ``` 76 | 77 | 2. Install dependencies 78 | ```bash 79 | pnpm install 80 | ``` 81 | 82 | 3. Run the project 83 | ```bash 84 | pnpm start 85 | ``` 86 | 87 | ## Usage 88 | 1. OpenAI Clients 89 | 90 | ![botgem](pictures/usage.png) 91 | 92 | 2.
