soap2rest 0.1.0

Convert any SOAP WSDL service to a REST API using FastAPI

soap2rest

Convert any SOAP WSDL service to a REST API using FastAPI.

Features

• 🔄 Automatic Conversion: Automatically converts SOAP operations to REST endpoints
• 🚀 FastAPI Powered: Built on FastAPI for high performance and automatic API documentation
• 🔧 Zero Configuration: No manual endpoint configuration needed
• 📚 Interactive Docs: Automatic Swagger/OpenAPI documentation at /docs
• 🛡️ Error Handling: Proper HTTP status codes for SOAP faults, timeouts, and connection errors
• ⚡ Async Support: Non-blocking SOAP calls using thread pool execution

Installation

From Source

git clone https://github.com/yourusername/soap2rest.git
cd soap2rest
pip install .

From PyPI (when published)

pip install soap2rest

Quick Start

1. Start the server with a WSDL URL:

soap2rest --wsdl https://www.dataaccess.com/webservicesserver/NumberConversion.wso?WSDL --port 8000

2. View the API documentation:

Open http://localhost:8000/docs in your browser to see the interactive Swagger UI.

3. Call the REST API:

curl -X POST http://localhost:8000/call/NumberToWords \
  -H "Content-Type: application/json" \
  -d '{"ubiNum": "123"}'

Usage

Basic Usage

soap2rest --wsdl <WSDL_URL> --port 8000

Advanced Options

soap2rest \
  --wsdl https://example.com/service.wsdl \
  --host 0.0.0.0 \
  --port 8000 \
  --workers 4 \
  --log-level info \
  --reload

Environment Variables

You can also configure the server using environment variables:

export SOAP2REST_WSDL="https://example.com/service.wsdl"
export SOAP2REST_PORT=8000
export SOAP2REST_HOST="0.0.0.0"
export SOAP2REST_WORKERS=4
export SOAP2REST_LOG_LEVEL="info"
export SOAP2REST_RELOAD="true"

soap2rest

Command Line Options

• --wsdl (required): WSDL URL or file path
• --host (default: 0.0.0.0): Host to bind to
• --port (default: 8000): Port to bind to
• --workers (default: 1): Number of worker processes
• --log-level (default: info): Logging level (critical, error, warning, info, debug, trace)
• --reload (default: false): Enable auto-reload for development
• --timeout-keep-alive (default: 5): Keep-alive timeout in seconds

How It Works

1. WSDL Parsing: The tool loads and parses the WSDL file/URL
2. Operation Discovery: Automatically discovers all SOAP operations
3. REST Endpoint Generation: Creates REST endpoints for each SOAP operation
4. Dynamic Model Creation: Generates Pydantic models for request validation
5. Request Processing: Converts REST requests to SOAP calls and returns JSON responses

Example

Given a SOAP service with operation NumberToWords, the tool automatically creates:

• GET / - Lists all available operations
• POST /call/NumberToWords - REST endpoint for the SOAP operation

Request:

POST /call/NumberToWords
{
  "ubiNum": "123"
}

Response:

{
  "result": "one hundred and twenty three "
}
