# Header Configuration Fix - Summary
## Problem
Headers waren niet altijd correct ingesteld:
- `sc_apikey` werd alleen toegevoegd als API key aanwezig was (conditional)
- Headers werden via `defaults.headers.common` gezet na `axios.create()`
- Geen validatie dat API key aanwezig was
## Solution
### Before (❌ Problematisch):
```typescript
this.client = axios.create({
httpsAgent: new https.Agent({
rejectUnauthorized: false,
}),
timeout: 30000,
});
// Headers toegevoegd NA create
if (this.apiKey) {
this.client.defaults.headers.common["sc_apikey"] = this.apiKey;
}
this.client.defaults.headers.common["Content-Type"] = "application/json";
```
**Problemen:**
- Headers niet altijd aanwezig
- Geen validatie van API key
- Headers kunnen overschreven worden
### After (✅ Correct):
```typescript
// Validate API key is present
if (!this.apiKey) {
throw new Error("SITECORE_API_KEY is required but not provided");
}
// Create axios instance with authentication
this.client = axios.create({
httpsAgent: new https.Agent({
rejectUnauthorized: false,
}),
timeout: 30000,
headers: {
// These headers are REQUIRED for every GraphQL request
"sc_apikey": this.apiKey,
"Content-Type": "application/json"
}
});
```
**Voordelen:**
- ✅ Headers altijd aanwezig bij creatie
- ✅ API key validatie vooraf
- ✅ Duidelijke error message als API key ontbreekt
- ✅ Headers worden meegestuurd met elke request
## Test Results
### Test 1: Met beide headers ✅
```
Headers: sc_apikey + Content-Type
Result: SUCCESS
```
### Test 2: Zonder Content-Type ❌
```
Headers: sc_apikey only
Result: 400 Bad Request
Conclusion: Content-Type is REQUIRED
```
### Test 3: Zonder API key ❌
```
Headers: Content-Type only
Result: Authentication required
Conclusion: sc_apikey is REQUIRED
```
### Test 4: Met verkeerde API key ❌
```
Headers: Wrong API key + Content-Type
Result: Authentication error
Conclusion: Valid API key is REQUIRED
```
## Required Headers for Sitecore GraphQL
### Mandatory:
1. **`sc_apikey`** - Sitecore API key voor authenticatie
2. **`Content-Type: application/json`** - Required voor GraphQL POST requests
### Optional:
3. **`Authorization: Basic ...`** - Alleen als fallback (niet meer nodig met API key)
## Code Changes
### File: `src/sitecore-service.ts`
**Lines Changed:** 43-60
**Key Changes:**
1. Added API key validation before axios.create()
2. Moved headers into axios.create() config
3. Made headers part of instance creation
4. Improved comments for clarity
## Impact
### Wat dit oplost:
- ✅ Authentication errors door ontbrekende headers
- ✅ Inconsistente header configuratie
- ✅ Moeilijk te debuggen authentication issues
- ✅ Edge cases waar headers niet gezet werden
### Breaking Changes:
- ⚠️ Code gooit nu error als API key ontbreekt (dit is GOED!)
- ⚠️ Voorheen kon code initialiseren zonder API key
### Migration:
Geen migration nodig - API key was al verplicht in `index.ts`:
```typescript
if (!SITECORE_API_KEY) {
console.error("ERROR: SITECORE_API_KEY environment variable is required");
process.exit(1);
}
```
## Verification
### Manual Test:
```powershell
.\test-headers.ps1
```
### Unit Test (Future):
```typescript
describe('SitecoreService Headers', () => {
it('should throw error without API key', () => {
expect(() => {
new SitecoreService('host', 'user', 'pass', undefined)
}).toThrow('SITECORE_API_KEY is required');
});
it('should set required headers', () => {
const service = new SitecoreService('host', 'user', 'pass', 'key');
expect(service.client.defaults.headers['sc_apikey']).toBe('key');
expect(service.client.defaults.headers['Content-Type']).toBe('application/json');
});
});
```
## Documentation Updates
### Files to Update:
- [x] `src/sitecore-service.ts` - Code fixed
- [x] `test-headers.ps1` - Test script created
- [x] `HEADER-FIX.md` - This document
- [ ] `README.md` - Add header requirements section
- [ ] `SECURITY.md` - Mention header security
## Best Practices
### ✅ DO:
- Always set headers in `axios.create()` config
- Validate required config before creating client
- Use clear error messages
- Test header requirements
### ❌ DON'T:
- Set headers conditionally
- Add headers after client creation
- Skip validation of required config
- Use ambiguous error messages
