# ShopDB API (ASP) - PowerShell Data Collection Endpoint

**File:** `api.asp`
**Created:** 2025-11-13
**Purpose:** Receive PC asset data from PowerShell scripts and store in Phase 2 schema
**Schema:** Phase 2 (machines, communications, machinerelationships)

---

## Overview

This ASP API replaces the PHP api.php and provides the same functionality but runs on IIS with the ShopDB ASP application. It's designed to work with Phase 2 schema from day one.

**Key Features:**
-  Uses Phase 2 schema (machines, communications)
-  Parameterized queries (SQL injection protection)
-  JSON request/response handling
-  Automatic vendor/model/pctype creation
-  PC-to-equipment relationship management
-  Network interface tracking
-  DNC configuration storage
-  Warranty data management
-  Application tracking

## Automatic Lookups

The API automatically creates records in these tables if they don't exist:

### vendors
- Created when new manufacturer is encountered
- Lookup: `SELECT vendorid FROM vendors WHERE vendor = ?`
- Create: `INSERT INTO vendors (vendor) VALUES (?)`

### models
- Created when new model is encountered for a vendor
- Lookup: `SELECT modelnumberid FROM models WHERE modelnumber = ? AND vendorid = ?`
- Create: `INSERT INTO models (modelnumber, vendorid, notes, isactive) VALUES (?, ?, 'Auto-imported via PowerShell', 1)`

### pctype
- Created when new PC type is encountered
- Lookup: `SELECT pctypeid FROM pctype WHERE typename = ?`
- Create: `INSERT INTO pctype (typename) VALUES (?)`

### operatingsystems
- Created when new OS version is encountered
- Lookup: `SELECT osid FROM operatingsystems WHERE osname = ?`
- Create: `INSERT INTO operatingsystems (osname) VALUES (?)`

### applications
- Created when new application is encountered
- Lookup: `SELECT applicationid FROM applications WHERE applicationname = ?`
- Create: `INSERT INTO applications (applicationname, version) VALUES (?, ?)`

---

## PC Type to Machine Type Mapping

When creating PCs, `machinetypeid` is automatically determined from `pctypeid`:

| PC Type Name | pctypeid | machinetypeid | Machine Type |
|--------------|----------|---------------|--------------|
| Engineer     | varies   | 30            | Workstation  |
| Shopfloor    | varies   | 28            | Desktop PC   |
| Standard     | varies   | 28            | Desktop PC   |
| Laptop       | varies   | 29            | Laptop       |
| Thin Client  | varies   | 31            | Thin Client  |
| Server       | varies   | 32            | Server       |

This mapping allows:
- PCs to be filtered with `WHERE pctypeid IS NOT NULL`
- PC-specific queries to join to `machinetypes` table
- Unified reporting across PCs and equipment

---

## Error Responses

All errors return HTTP 200 with JSON:

```json
{
  "success": false,
  "error": "Error message here"
}
```

**Common Errors:**
- `"hostname and serialNumber are required"` - Missing required fields
- `"PC not found: HOSTNAME"` - PC doesn't exist in database
- `"Printer not found: FQDN"` - Printer not found by FQDN or IP
- `"Failed to insert/update PC: SQL error"` - Database error
- `"Invalid action: ACTION"` - Unknown action parameter

---

## Security Features

### SQL Injection Protection
All queries use parameterized commands:
```asp
Set cmd = Server.CreateObject("ADODB.Command")
cmd.ActiveConnection = objConn
cmd.CommandText = "SELECT machineid FROM machines WHERE hostname = ?"
cmd.Parameters.Append cmd.CreateParameter("@hostname", 200, 1, 100, hostname)
Set rsResult = cmd.Execute
```

### Input Validation
- Required field checks
- Numeric validation for IDs
- Boolean conversion for true/false values
- String length limits enforced

### HTML/JSON Escaping
- All JSON output properly escaped
- Special characters handled: `\`, `"`, CR, LF, TAB

---

## Logging

API logs to: `/logs/api.log`

**Log Format:** `YYYY-MM-DD HH:MM:SS - Message`

**Logged Events:**
- New requests with hostname/serial/pctype
- Vendor/Model/PCType ID lookups
- Record creation (machineid)
- Network interface insertion counts
- Comm config insertion counts
- DNC config insertion success
- PC-Machine relationship creation
- Errors with full error descriptions

**Log Directory:** Must exist and be writable by IIS process

---

## PowerShell Integration

### Default URL Configuration

PowerShell scripts should use:
```powershell
$DashboardURL = "http://192.168.122.151:8080/api.asp"
```

### Example PowerShell Call

```powershell
$postData = @{
    action = 'updateCompleteAsset'
    hostname = $env:COMPUTERNAME
    serialNumber = $serialNumber
    manufacturer = $manufacturer
    model = $model
    pcType = "Shopfloor"
    loggedInUser = $env:USERNAME
    machineNo = "2001"
    osVersion = $osVersion
    networkInterfaces = $networkInterfacesJSON
    commConfigs = $commConfigsJSON
    dncConfig = $dncConfigJSON
    dncDualPathEnabled = $true
    dncPath1Name = "Path1"
    dncPath2Name = "Path2"
}

$response = Invoke-RestMethod -Uri $DashboardURL -Method Post -Body $postData
```

---

## Testing

### Test 1: Health Check
```bash
curl "http://192.168.122.151:8080/api.asp?action=getDashboardData"
```

**Expected:**
```json
{"success":true,"message":"ShopDB API is online","version":"1.0","schema":"Phase 2"}
```

### Test 2: Create New PC
```powershell
$postData = @{
    action = 'updateCompleteAsset'
    hostname = 'TEST-PC-01'
    serialNumber = 'ABC123456'
    manufacturer = 'Dell'
    model = 'OptiPlex 7090'

```sql
SELECT
    equipment.machinenumber AS equipment,
    pc.hostname AS controlling_pc
FROM machinerelationships mr
JOIN machines equipment ON mr.machineid = equipment.machineid
JOIN machines pc ON mr.related_machineid = pc.machineid
JOIN relationshiptypes rt ON mr.relationshiptypeid = rt.relationshiptypeid
WHERE equipment.machinenumber = '2001' AND rt.relationshiptype = 'Controls';
```

---

## Deployment

### Step 1: Database Schema Update

Run the migration script:
```bash
mysql -h 192.168.122.1 -u root -p shopdb < sql/migration_phase2/08_update_schema_for_api.sql
```

This renames `pcid` → `machineid` in:
- `commconfig`
- `dncconfig`

### Step 2: Deploy api.asp

Copy `api.asp` to ShopDB root directory:
```bash
cp api.asp /home/camp/projects/windows/shopdb/
```

### Step 3: Create Logs Directory

Ensure logs directory exists and is writable:
```bash
mkdir -p /home/camp/projects/windows/shopdb/logs
chmod 755 /home/camp/projects/windows/shopdb/logs
```

### Step 4: Update PowerShell Scripts

Change default dashboard URL in `Update-PC-CompleteAsset.ps1`:
```powershell
# OLD:
[string]$DashboardURL = "http://10.48.130.197/dashboard-v2/api.php"

# NEW:
[string]$DashboardURL = "http://192.168.122.151:8080/api.asp"
```

### Step 5: Test

Run PowerShell script on one test PC:
```powershell
.\Update-PC-CompleteAsset.ps1
```

Check logs:
```bash
tail -f /home/camp/projects/windows/shopdb/logs/api.log
```

Verify in ShopDB:
```
http://192.168.122.151:8080/displaypcs.asp
```

## Troubleshooting

### Issue: "Object required" error

**Cause:** RegExp object not created properly

**Fix:** Check that VBScript RegExp is enabled:
```asp
Dim regex
Set regex = New RegExp
```

### Issue: "ADO error" when inserting

**Cause:** Parameter type mismatch

**Fix:** Verify parameter types match database column types:
- VARCHAR: `200` (adVarChar)
- INT: `3` (adInteger)
- DATE: `135` (adDBDate)
- TINYINT: `16` (adTinyInt)

### Issue: Network interfaces not appearing

**Cause:** `comstypeid` not set correctly

**Fix:** Ensure `comstypeid = 1` for network interfaces

### Issue: PC relationships not created

**Cause:** Equipment with matching machine number doesn't exist

**Fix:** Ensure equipment record exists with `pctypeid IS NULL` and matching `machinenumber`

### Issue: Logs not writing

**Cause:** Logs directory doesn't exist or isn't writable

**Fix:**
```bash
mkdir -p /home/camp/projects/windows/shopdb/logs
chmod 755 /home/camp/projects/windows/shopdb/logs
```

## Performance Considerations

### Indexes Required

Ensure these indexes exist for optimal performance:

```sql
-- machines table
ALTER TABLE machines ADD INDEX idx_hostname (hostname);
ALTER TABLE machines ADD INDEX idx_pctypeid (pctypeid);
ALTER TABLE machines ADD INDEX idx_machinenumber (machinenumber);

-- communications table
ALTER TABLE communications ADD INDEX idx_machineid (machineid);
ALTER TABLE communications ADD INDEX idx_comstypeid (comstypeid);

-- commconfig table
ALTER TABLE commconfig ADD INDEX idx_machineid (machineid);

-- dncconfig table
ALTER TABLE dncconfig ADD INDEX idx_machineid (machineid);

-- machinerelationships table
ALTER TABLE machinerelationships ADD INDEX idx_machineid (machineid);
ALTER TABLE machinerelationships ADD INDEX idx_related_machineid (related_machineid);
```

### Query Optimization

- Uses parameterized queries for all SELECT/INSERT/UPDATE operations
- Deletes old records before inserting new (avoids duplicate detection overhead)
- Single transaction per request (faster than individual commits)
- Lookup caching could be added for frequently accessed vendor/model/pctype IDs

---

## Maintenance

### Log Rotation

Recommend setting up log rotation for `/logs/api.log`:

**Windows Task Scheduler:**
```powershell
# Rotate logs weekly
Get-Content "C:\inetpub\wwwroot\shopdb\logs\api.log" |
    Set-Content "C:\inetpub\wwwroot\shopdb\logs\api_$(Get-Date -Format 'yyyyMMdd').log"
Clear-Content "C:\inetpub\wwwroot\shopdb\logs\api.log"
```

### Monitoring

Monitor these metrics:
- Request count per hour
- Error rate (failed requests / total requests)
- Average response time
- Database connection pool usage
- Disk space for logs directory

---

## Future Enhancements

### Planned Features:
1. **Batch Processing**: Accept arrays of PCs in single request
2. **Delta Updates**: Only update changed fields (reduces write load)
3. **Webhook Callbacks**: Notify on successful PC creation
4. **API Key Authentication**: Secure API access
5. **Rate Limiting**: Prevent abuse
6. **Caching Layer**: Cache vendor/model/pctype lookups
7. **Async Processing**: Queue large updates for background processing

### Nice to Have:
- GraphQL endpoint for flexible queries
- WebSocket support for real-time updates
- OpenAPI/Swagger documentation
- Postman collection for testing
- Health metrics endpoint (uptime, request count, error rate)
