# PDF Text Extraction - Quick Start Guide
|
||||||
|
|
||||||
|
## Components
|
||||||
|
|
||||||
|
1. **PDF Extractor CLI** (`pdf_extractor.py`) - Command-line tool for local files and URLs
|
||||||
|
2. **PDF Daemon API** (`pdf_daemon.py`) - FastAPI service for programmatic access
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Option 1: CLI Tool (Simple)
|
||||||
|
|
||||||
|
### Usage
|
||||||
|
```bash
|
||||||
|
# Extract from local file (auto-saves to same directory with .txt extension)
|
||||||
|
python3 pdf_extractor.py document.pdf
|
||||||
|
|
||||||
|
# With custom output path
|
||||||
|
python3 pdf_extractor.py document.pdf --output result.txt
|
||||||
|
|
||||||
|
# From URL (downloads and extracts, saves to current directory)
|
||||||
|
python3 pdf_extractor.py https://example.com/doc.pdf
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Option 2: API Daemon (Service Mode)
|
||||||
|
|
||||||
|
### Start the daemon
|
||||||
|
```bash
|
||||||
|
# Using uvicorn (default port 8000)
|
||||||
|
uvicorn pdf_daemon:app --host 0.0.0.0 --port 8000
|
||||||
|
|
||||||
|
# Or run directly with custom port
|
||||||
|
python3 pdf_daemon.py --port 5006
|
||||||
|
```
|
||||||
|
|
||||||
|
### API Endpoints
|
||||||
|
|
||||||
|
**Health Check:**
|
||||||
|
```bash
|
||||||
|
curl http://localhost:8000/health
|
||||||
|
```
|
||||||
|
|
||||||
|
**Extract PDF from URL:**
|
||||||
|
```bash
|
||||||
|
curl "http://localhost:8000/extract?url=https://example.com/doc.pdf"
|
||||||
|
```
|
||||||
|
|
||||||
|
**With custom output file:**
|
||||||
|
```bash
|
||||||
|
curl "http://localhost:8000/extract?url=https://example.com/doc.pdf&output_file=result.txt"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Python Client Example
|
||||||
|
```python
|
||||||
|
import requests
|
||||||
|
|
||||||
|
response = requests.get(
|
||||||
|
"http://localhost:8000/extract",
|
||||||
|
params={"url": "https://example.com/doc.pdf"}
|
||||||
|
)
|
||||||
|
|
||||||
|
data = response.json()
|
||||||
|
print(data['text'])
|
||||||
|
print(f"Extracted in {data['extraction_time_ms']:.2f}ms")
|
||||||
|
```
|
||||||

}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage Examples
|
||||||
|
|
||||||
|
### cURL examples:
|
||||||
|
|
||||||
|
**Extract text from PDF URL:**
|
||||||
|
```bash
|
||||||
|
curl "http://localhost:8000/extract?url=https://www.pdf995.com/samples/pdf.pdf"
|
||||||
|
```
|
||||||
|
|
||||||
|
**Extract and save to custom file:**
|
||||||
|
```bash
|
||||||
|
curl "http://localhost:8000/extract?url=https://www.pdf995.com/samples/pdf.pdf&output_file=my_output.txt"
|
||||||
|
```
|
||||||
|
|
||||||
|
**Check health:**
|
||||||
|
```bash
|
||||||
|
curl http://localhost:8000/health
|
||||||
|
```
|
||||||
|
|
||||||
|
### Python example:
|
||||||
|
|
||||||
|
```python
|
||||||
|
import requests
|
||||||
|
|
||||||
|
response = requests.get(
|
||||||
|
"http://localhost:8000/extract",
|
||||||
|
params={
|
||||||
|
"url": "https://example.com/document.pdf"
|
||||||
|
}
|
||||||
|
)
|
||||||
|
|
||||||
|
data = response.json()
|
||||||
|
print(f"Extracted {data['pages']} pages in {data['extraction_time_ms']:.2f}ms")
|
||||||
|
print(data['text'])
|
||||||
|
```
|
||||||
|
|
||||||
|
## Performance
|
||||||
|
|
||||||
|
Using PyMuPDF (fitz), extraction is extremely fast:
|
||||||
|
|
||||||
|
| File Size | Pages | Time |
|
||||||
|
|-----------|-------|------|
|
||||||
|
| 423 KB | 5 | ~90ms |
|
||||||
|
| 1.2 MB | ~80 | ~260ms |
|
||||||
|
|
||||||
|
## Error Handling
|
||||||
|
|
||||||
|
The API returns appropriate HTTP status codes:
|
||||||
|
|
||||||
|
- `400` - Invalid URL or request format
|
||||||
|
- `404` - PDF not found at URL
|
||||||
|
- `500` - Server error (download/Extraction failed)
|
||||||
|
|
||||||
|
**Error Response:**
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"detail": "Failed to download PDF: 404"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Notes
|
||||||
|
|
||||||
|
### CLI Tool (`pdf_extractor.py`)
|
||||||
|
- Saves output to same directory as source PDF by default (with `.txt` extension)
|
||||||
|
- Use `--output` flag for custom output path
|
||||||
|
|
||||||
|
### API Daemon (`pdf_daemon.py`)
|
||||||
|
- Extracted text is always returned in the JSON response
|
||||||
|
- Optional `output_file` parameter saves a copy to `/tmp/` on the server
|
||||||
|
- Maximum download timeout: 60 seconds
|
||||||
|
- Supports both HTTP and HTTPS URLs
