Starting the Server

Local Start

Environment Variables

1. API_PASSWORD - The password used when making API requests, passed through the any2api-key header. Leave empty to disable authentication.
2. API_TIMEOUT - The timeout duration in seconds. Default is 30 seconds.

After installing the node environment, run cd api && node app.js.

Docker-compose

Run docker-compose up -d in the root directory.

Docker

docker build -t any2api . && docker run -p 9000:9000 -v $(pwd)/api/filter:/app/filter -v $(pwd)/api/ssl:/app/ssl any2api

Connection Service

1. Select Enable
2. Click Save Connection

To reconnect:

1. Click Disconnect
2. Select Enable
3. Click Save Connection

API Requests

1. /send - Send a standard HTTP request.

   1. url: Passed through query, needs to be URL-encoded.
   2. any2api-key: Passed through header, specified during startup through the environment variable API_PASSWORD.
   3. Other method, headers, and body will be forwarded as is.
   4. The response headers returned are from the browser plugin.

2. /stream - Send SSE (Server-Sent Events) request.

   1. url: Passed through query, needs to be URL-encoded.
   2. any2api-key: Passed through header, specified during startup through the environment variable API_PASSWORD.
   3. Other method, headers, and body will be forwarded as is.
   4. The response headers returned are forcibly replaced with:

   res.writeHead(200, {
       'Content-Type': 'text/event-stream;charset=utf-8',
       'Cache-Control': 'no-cache',
       'Connection': 'keep-alive'
   });
   

3. /:domain/v1/chat/completions - Alias for /stream, used for compatibility with certain OpenAI clients.

Custom Services

SSL Certificate

Place under api/ssl:

1. api/ssl/ssl.cert - Certificate file.
2. api/ssl/ssl.key - Private key file.

Data Filter

1. Create a directory under api/filter based on the request domain.
2. The directory supports three types of files:
   1. in.js - Filter for the data received on the server before being sent to the browser plugin.
   2. out.js - Filter for the data returned by the browser plugin to the server before being sent back.
   3. chunk.js - Filter for the data returned by the browser plugin to the server in Server-Sent Events mode, for each returned chunk.

The format for writing the filters is as follows:

module.exports = function filter(data) {
    return {...data, headers:{...data.headers, "ai-api":"very-good" }};
}

The data in the in filter includes:

let payload = {
        url: url,
        headers: headers,
        body: body,
        method: req.method
    };

The data in the out filter includes:

let payload = {
    headers: ret.headers,
    body: ret.any2api
}

The data in the chunk filter includes:

let chunkInfo = JSON.parse(chunk);
