QHTTP: Expose IBM i Stored Procedures and Programs as Web Services

QHTTP is a Golang application designed to seamlessly expose IBM i (AS/400) stored procedures and programs as web services. With QHTTP , you can easily integrate your existing IBM i applications with modern web applications or other systems that communicate via HTTP.

Features

Effortless Integration: Connect your IBM i applications to the web without the need for complex middleware or extensive modifications to your existing codebase.
Secure Communication: QHTTP supports HTTPS, ensuring secure communication between your IBM i server and clients.
High Performance: Built with Golang's concurrency and efficiency in mind, qhttp delivers high performance for handling web service requests.
Customizable: Easily configure endpoints, request handling, and security settings to suit your specific requirements.
Logging and Monitoring: QHTTP provides comprehensive logging capabilities, allowing you to monitor and analyze web service usage and performance.

Getting Started

Supported platforms

Linux
Windows

Prerequisites

Before installing and running qhttp, ensure you have the following prerequisites:

IBM i server with stored procedures or programs you want to expose as web services.
Go 1.20.5 or latest installed on your development machine

Installation


git clone https://github.com/zerobit-tech/GoQhttp.git

Run QHTTP


go mod tidy


go run ./cmd/web --https=false

By default, qhttp will listen on port 4081. You can customize the port by modifying the PORT env var if needed.

Default user name [email protected] Default password adminpass

Security Considerations

It's important to ensure that your QHTTP server is adequately secured, especially if it's exposed to the internet. QHTTP comes with an self signed certificate. We recommand to use a reverse proxy service like caddy.

Vendor for simplify dependency management

go mod vendor : Create a Vendor Directory
go mod vendor -u :Update the Vendor Directory
export GOFLAGS=-mod=vendor : By setting GOFLAGS, you can ensure that all builds use the vendor directory
