## Полный workflow
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
[Code: Process Flights Data] ← Генерирует HTML
|
|||
|
|
↓
|
|||
|
|
[Code: HTML to Base64] ← Конвертирует HTML в base64 (если нужно)
|
|||
|
|
↓
|
|||
|
|
[HTTP Request: Browserless PDF] ← Используйте настройки выше
|
|||
|
|
↓
|
|||
|
|
[Code: Extract Base64 PDF] ← Конвертирует binary в base64
|
|||
|
|
```
|
|||
|
|

|
|
|||
|
|
## Code Node: HTML to Base64 (если нужно)
|
|||
|
|
|
|||
|
|
Если у вас HTML в строке, а нужен base64 для data URL:
|
|||
|
|
|
|||
|
|
```javascript
|
|||
|
|
const html = $json.html;
|
|||
|
|
const htmlBase64 = Buffer.from(html, 'utf8').toString('base64');
|
|||
|
|
|
|||
|
|
return [{
|
|||
|
|
json: {
|
|||
|
|
html_base64: htmlBase64,
|
|||
|
|
html: html
|
|||
|
|
}
|
|||
|
|
}];
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## Code Node: Extract Base64 PDF (после HTTP Request)
|
|||
|
|
|
|||
|
|
```javascript
|
|||
|
|
const pdfBinary = $binary.data;
|
|||
|
|
const base64 = Buffer.isBuffer(pdfBinary)
|
|||
|
|
? pdfBinary.toString('base64')
|
|||
|
|
: Buffer.from(pdfBinary).toString('base64');
|
|||
|
|
|
|||
|
|
const sizeBytes = Buffer.from(base64, 'base64').length;
|
|||
|
|
|
|||
|
|
return [{
|
|||
|
|
json: {
|
|||
|
|
pdf_base64: base64,
|
|||
|
|
pdf_size_bytes: sizeBytes,
|
|||
|
|
pdf_size_mb: (sizeBytes / (1024 * 1024)).toFixed(2),
|
|||
|
|
success: true
|
|||
|
|
}
|
|||
|
|
}];
|
|||
|
|
```
|

## Отладка
|
|||
|
|
|
|||
|
|
Если получаете ошибку:
|
|||
|
|
- **"Bad or missing authentication"** → Проверьте токен или уберите Authorization header
|
|||
|
|
- **"Not Found"** → Проверьте URL эндпоинта
|
|||
|
|
- **Пустой ответ** → Проверьте формат HTML и data URL
