Library Information

Purpose

Provides a client for the authz-service, handling privilege management for users across companies. Used by all microservices that need to check user permissions.

Usage

import client "git.unbound.se/shiny/authz_client"

// Create handler with options
handler := client.New(client.WithBaseURL("http://authz-service"))

// Check user privileges
privileges := handler.Get(email, companyID)
if privileges.Invoicing {
    // User has invoicing privileges
}

Privileges

The CompanyPrivileges struct contains permission flags:

• Admin - Administrative access
• Company - Company management
• Consumer - Consumer/customer access
• Time - Time tracking
• Invoicing - Invoice management
• Accounting - Accounting access
• Supplier - Supplier management
• Salary - Salary/payroll access

Event Handling

Implements goamqp message handlers to receive privilege update events from the authz-service, keeping the local privilege cache up-to-date.
