# OpenFUT Bridge

**FIFA 23 integration layer and reverse-engineering proxy.**

OpenFUT Bridge sits between the FIFA 23 client and the internet. It intercepts all FUT API traffic, logs every request, and routes known endpoints to OpenFUT Core. Unknown endpoints receive safe placeholder responses so the client keeps running.

---

## What it does

- Transparent HTTP proxy — point FIFA 23 here instead of EA's servers
- Logs every request (method, path, headers, body, timestamp) to `captures/`
- Maps known FUT endpoints to OpenFUT Core API calls
- Returns placeholder JSON for unknown endpoints (prevents client crashes)
- Admin API for reviewing captures and identifying unmapped routes
- Foundation for building the full FIFA 23 integration

## Architecture

```
FIFA 23 client
      │
      ▼
OpenFUT Bridge (port 8443)
      │
      ├── Known route → OpenFUT Core (port 8080)
      └── Unknown route → Placeholder JSON + saved to captures/
```

---

## Quick Start

```bash
# Run Core first
cd ../openfut-core && cargo run

# Run Bridge
cargo run

# Or with config
CORE_URL=http://127.0.0.1:8080 BRIDGE_LISTEN_ADDR=127.0.0.1:8443 cargo run
```

### Environment Variables

| Variable | Default | Description |
|---|---|---|
| `BRIDGE_LISTEN_ADDR` | `127.0.0.1:8443` | Bridge listen address |
| `CORE_URL` | `http://127.0.0.1:8080` | OpenFUT Core URL |
| `CAPTURES_DIR` | `captures` | Where to save captured requests |
| `PLACEHOLDER_MODE` | `true` | Return 200 for unknown endpoints |

---

## Admin API

| Method | Path | Description |
|---|---|---|
| `GET` | `/_bridge/health` | Bridge status |
| `GET` | `/_bridge/captures` | All captured requests |
| `GET` | `/_bridge/unknown` | Unknown endpoints only |

---

## Reverse Engineering Workflow

1. Point FIFA 23 at the Bridge (see `docs/setup-notes.md` for proxy setup)
2. Start a game session
3. Check `captures/` or `/_bridge/unknown` for new endpoints
4. Document the endpoint in `docs/endpoint-map.md`
5. Add a mapping in `src/mapper.rs`
6. Implement the Core handler

## Proxy Setup (Research Notes)

See `docs/setup-notes.md` for notes on:
- Windows `hosts` file redirection
- RPCS3 network config (PS3)
- Certificate bypass approaches
- mitmproxy integration

## Development

```bash
cargo fmt
cargo clippy -- -D warnings
cargo test
```
