# RMTO Service Tests - Fixed Issues

## Issues Found and Fixed

### 1. **GetDriverByNational_ID Parameter Name Mismatch**
- **Problem**: Used `<tem:NationalId>` instead of `<tem:code>`
- **Solution**: Changed parameter name to `code` to match WSDL specification
- **File**: `app/Services/RMTOService.php` - Line 147
- **Method**: `getDriverByNationalId()`

### 2. **GetDriverBySmartCardNo Parameter Name Mismatch**
- **Problem**: Used `<tem:CardNumber>` instead of `<tem:code>`
- **Solution**: Changed parameter name to `code` to match WSDL specification
- **File**: `app/Services/RMTOService.php` - Line 121
- **Method**: `getDriverBySmartCardNo()`

### 3. **GetFreighterBySmartCardNo Parameter Name Mismatch**
- **Problem**: Used `<tem:CardNumber>` instead of `<tem:CardNo>`
- **Solution**: Changed parameter name to `CardNo` to match WSDL specification
- **File**: `app/Services/RMTOService.php` - Line 173
- **Method**: `getFreighterBySmartCardNo()`

### 4. **LoadBillOfLadingByNumber Parameter Names Mismatch**
- **Problem**: Used `<tem:BillNumber>` and `<tem:BillSerial>` instead of `<tem:number>` and `<tem:serial>`
- **Solution**: Changed parameter names to `number` and `serial` (in that order) to match WSDL specification
- **File**: `app/Services/RMTOService.php` - Lines 225-226
- **Method**: `loadBillOfLadingByNumber()`

### 5. **Improper Response Parsing for Driver Information**
- **Problem**: Used generic `parseResponse()` with JSON conversion which doesn't properly extract nested XML elements with namespaces
- **Solution**: Implemented specialized `parseDriverResponse()` method with proper XPath namespace handling
- **File**: `app/Services/RMTOService.php` - New method at line 366
- **Method**: `parseDriverResponse()`

### 6. **Improper Response Parsing for Freighter Information**
- **Problem**: Used generic `parseResponse()` with JSON conversion
- **Solution**: Implemented specialized `parseFreighterResponse()` method with proper XPath namespace handling
- **File**: `app/Services/RMTOService.php` - New method at line 408
- **Method**: `parseFreighterResponse()`

### 7. **Improper Response Parsing for Bill of Lading**
- **Problem**: Used generic `parseResponse()` with JSON conversion
- **Solution**: Implemented specialized `parseBillOfLadingResponse()` method with proper XPath namespace handling
- **File**: `app/Services/RMTOService.php` - New method at line 449
- **Method**: `parseBillOfLadingResponse()`

## Root Cause Analysis

The main issues stemmed from:
1. **Parameter naming mismatches with WSDL specification** - The XML element names in the SOAP request didn't match what the RMTO SOAP service expected
2. **Inadequate response parsing** - The generic JSON conversion approach doesn't work well with namespaced XML where elements are nested under different namespace prefixes (e.g., `a:Name`, `a:NationalId`, etc.)

## Testing

A test script (`test_rmto_fixes.php`) was created to verify:
- ✓ Driver information response parsing
- ✓ SOAP request XML structure for all fixed methods
- ✓ Proper parameter naming conventions

## Affected Endpoints

The following admin panel endpoints should now work correctly:
- `GET /admin/rmto/driver-info` (both smart card and national ID)
- `GET /admin/rmto/freighter-info`
- `GET /admin/rmto/bill-of-lading`
- All RMTO test endpoints in the admin panel

## Implementation Details

### Parameter Name Corrections

| Method | Parameter | Old Name | New Name | WSDL Reference |
|--------|-----------|----------|----------|-----------------|
| GetDriverByNational_ID | National ID code | NationalId | code | Line 147 |
| GetDriverBySmartCardNo | Card number | CardNumber | code | Line 121 |
| GetFreighterBySmartCardNo | Card number | CardNumber | CardNo | Line 173 |
| LoadBillOfLadingByNumber | Bill number | BillNumber | number | Line 226 |
| LoadBillOfLadingByNumber | Bill serial | BillSerial | serial | Line 225 |

### Response Parsing Improvements

Each specialized parsing method:
1. Registers the proper XML namespaces (`s` for SOAP envelope, `a` for data contracts)
2. Uses XPath queries to extract specific elements
3. Handles missing elements gracefully with empty string defaults
4. Returns structured array with snake_case keys

## Backward Compatibility

These changes fix the broken functionality without breaking any existing working code. The `getCurrentDate()` method continues to work as before since it was already using XPath correctly.

## Verification Steps

1. Run test script: `php test_rmto_fixes.php`
2. Test GetRmtoCurrentDate endpoint (should still work)
3. Test GetDriverByNational_ID endpoint with valid national code
4. Test GetDriverBySmartCardNo endpoint with valid card number
5. Test GetFreighterBySmartCardNo endpoint with valid card number
6. Test LoadBillOfLadingByNumber endpoint with valid bill number and serial
