Introduction

Supports dual models, provides two unofficial ChatGPT API methods:

Method	Free?	Reliability	Quality
ChatGPTAPI(gpt-3.5-turbo-0301)	No	Reliable	Relatively clumsy
ChatGPTUnofficialProxyAPI(Web accessToken)	Yes	Relatively unreliable	Smart

Comparison:

1. ChatGPTAPI uses gpt-3.5-turbo-0301 to simulate ChatGPT through the official OpenAI completion API (the most reliable method, but it is not free and does not use models specifically tuned for chat).
2. ChatGPTUnofficialProxyAPI accesses ChatGPT's backend API via an unofficial proxy server to bypass Cloudflare (uses the real ChatGPT, is very lightweight, but depends on third-party servers and has rate limits).

Details

Switching Methods:

1. Go to the service/.env.example file and copy the contents to the service/.env file.
2. For OpenAI API Key, fill in the OPENAI_API_KEY field (Get apiKey).
3. For Web API, fill in the OPENAI_ACCESS_TOKEN field (Get accessToken).
4. When both are present, OpenAI API Key takes precedence.

Reverse Proxy:

Available when using ChatGPTUnofficialProxyAPI.Details

# service/.env
API_REVERSE_PROXY=

Environment Variables:

For all parameter variables, check here or see:

/service/.env

Roadmap

[✓] Dual models

[✓] Multiple session storage and context logic

[✓] Formatting and beautifying code-like message types

[✓] Access rights control

[✓] Data import and export

[✓] Save message to local image

[✓] Multilingual interface

[✓] Interface themes

[✗] More...

Prerequisites

Node

node requires version ^16 || ^18 (node >= 14 requires installation of fetch polyfill), and multiple local node versions can be managed using nvm.

node -v

PNPM

If you have not installed pnpm before:

npm install pnpm -g

Fill in the Keys

Get Openai Api Key or accessToken and fill in the local environment variables jump

# service/.env file

# OpenAI API Key - https://platform.openai.com/overview
OPENAI_API_KEY=

# change this to an `accessToken` extracted from the ChatGPT site's `https://chat.openai.com/api/auth/session` response
OPENAI_ACCESS_TOKEN=

Install Dependencies

To make it easier for backend developers to understand, we did not use the front-end workspace mode, but stored it in different folders. If you only need to do secondary development of the front-end page, delete the service folder.

Backend

Enter the /service folder and run the following command

pnpm install

Frontend

Run the following command in the root directory

pnpm bootstrap

Run in Test Environment

Backend Service

Enter the /service folder and run the following command

pnpm start

Frontend Webpage

Run the following command in the root directory

pnpm dev

Manual packaging

Backend service

If you don't need the node interface of this project, you can skip the following steps.

Copy the service folder to a server that has a node service environment.

# Install
pnpm install

# Build
pnpm build

# Run
pnpm prod

PS: You can also run pnpm start directly on the server without packaging.

Frontend webpage

1. Refer to the root directory .env.example file content to create .env file, modify VITE_GLOB_API_URL in .env at the root directory to your actual backend interface address.
2. Run the following command in the root directory and then copy the files in the dist folder to the root directory of your website service.

Reference information

pnpm build

Frequently Asked Questions

Q: Why does Git always report an error when committing?

A: Because there is submission information verification, please follow the Commit Guidelines.

Q: Where to change the request interface if only the frontend page is used?

A: The VITE_GLOB_API_URL field in the .env file at the root directory.

Q: All red when saving the file?

A: For vscode, please install the recommended plug-in of the project or manually install the Eslint plug-in.

Q: Why doesn't the frontend have a typewriter effect?

A: One possible reason is that after Nginx reverse proxying, buffering is turned on, and Nginx will try to buffer a certain amount of data from the backend before sending it to the browser. Please try adding proxy_buffering off; after the reverse proxy parameter and then reloading Nginx. Other web server configurations are similar.

Q: The content returned is incomplete?

A: There is a length limit for the content returned by the API each time. You can modify the VITE_GLOB_OPEN_LONG_REPLY field in the .env file under the root directory, set it to true, and rebuild the front-end to enable the long reply feature, which can return the full content. It should be noted that using this feature may bring more API usage fees.
