|
||||
|
||||
## 🎯 Response Format Compatibility
|
||||
|
||||
### APK Expects:
|
||||
```json
|
||||
{
|
||||
"resultCode": 0,
|
||||
"message": "Success",
|
||||
"data": { ... }
|
||||
}
|
||||
```
|
||||
|
||||
### Server Returns:
|
||||
```csharp
|
||||
public class SynergyResponse<T>
|
||||
{
|
||||
public int resultCode { get; set; }
|
||||
public string message { get; set; }
|
||||
public T data { get; set; }
|
||||
}
|
||||
```
|
||||
|
||||
**Status**: ✅ **PERFECT MATCH**
|
||||
|
||||
---
|
||||
|
||||
## 🔐 Authentication & Headers
|
||||
|
||||
### APK Sends:
|
||||
| Header | Value | Server Handles? |
|
||||
|--------|-------|-----------------|
|
||||
| `EAM-SESSION` | Session UUID | ✅ Logged & stored in context |
|
||||
| `EAM-USER-ID` | Synergy ID | ✅ Logged & stored in context |

|
||||
|
||||
---
|
||||
|
||||
## 🔒 SSL/TLS Compatibility
|
||||
|
||||
### APK SSL Configuration:
|
||||
```java
|
||||
// APK accepts ANY SSL certificate!
|
||||
HttpsURLConnection.setDefaultHostnameVerifier(
|
||||
SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER
|
||||
);
|
||||
```
|
||||
|
||||
**This means:**
|
||||
- ✅ Self-signed certificates work
|
||||
- ✅ No need for CA-signed cert
|
||||
- ✅ Community server can use dev certs
|
||||
|
||||
### Server Configuration:
|
||||
```csharp
|
||||
app.UseHttpsRedirection(); // Enforces HTTPS
|
||||
```
|
||||
|
||||
**Status**: ✅ **COMPATIBLE** - APK will accept your self-signed cert
|
||||
|
||||

|
||||
|
||||

||||

||||

```
|
||||
|
||||
**When Discord provides assets:**
|
||||
1. Place .pak files in `E:\rr3\RR3CommunityServer\RR3CommunityServer\Assets\downloaded\`
|

|
||||
## 🔧 What Happens When Assets Arrive?
|
||||
|
||||
### Step-by-Step Integration:
|
||||
|
||||
1. **Discord provides .pak files**
|
||||
```bash
|
||||
# Place files in:
|
||||
E:\rr3\RR3CommunityServer\RR3CommunityServer\Assets\downloaded\
|
||||
```
|
||||
|
||||
2. **Server automatically detects & serves them**
|
||||
- AssetsController handles `/content/api/{path}` requests
|
||||
- MD5 verification ensures integrity
|
||||
- Range requests allow resume
|
||||
|
||||
3. **Import manifest data to database**
|
||||
```powershell
|
||||
# Parse manifests and populate GameAssets table
|
||||
.\import-manifests.ps1
|
||||
```
|
||||
|
||||
4. **Modify APK** to point to your server
|
||||
- Change Director URL from `syn-dir.sn.eamobile.com` → `your-server-ip:5001`
|
||||
- Or use DNS/hosts file redirect
|
||||
|
||||
5. **Game downloads assets from your server!**
|
||||
- APK requests: `https://your-server:5001/content/api/gui_assets/...`
|
||||
- Server serves: `Assets/downloaded/gui_assets/...`
|
||||
- Profit! 🎮
|
||||

|

|
||||
## 🚀 APK Modification Required
|
||||
|
||||
### Option 1: Recompile APK (Recommended)
|
||||
|
||||
**Steps:**
|
||||
1. Decompile APK with apktool
|
||||
2. Find Director URL in `res/values/strings.xml` or native libs
|
||||
3. Replace `https://syn-dir.sn.eamobile.com` with `https://YOUR_SERVER_IP:5001`
|
||||
4. Recompile & sign APK
|
||||
|
||||
### Option 2: Hosts File Redirect (Easier)
|
||||
|
||||
**On Android device:**
|
||||
```bash
|
||||
# Root required
|
||||
# Add to /system/etc/hosts:
|
||||
YOUR_SERVER_IP syn-dir.sn.eamobile.com
|
||||
YOUR_SERVER_IP cloudcell.ea.com
|
||||
```
|
||||
|
||||
**On Windows (for emulator):**
|
||||
```powershell
|
||||
# C:\Windows\System32\drivers\etc\hosts
|
||||
192.168.1.100 syn-dir.sn.eamobile.com
|
||||
192.168.1.100 cloudcell.ea.com
|
||||
```
|
||||
|
||||
### Option 3: Network Proxy (Most Flexible)
|
||||
|
||||
Use mitmproxy or similar to redirect EA domains to your server.

|
||||
- [ ] Install modded APK on emulator
|
||||
- [ ] Launch game & verify Director response
|
||||

|
||||
|
||||
### Priority 3 (Polish):
|
||||
