Corporate Network Message Client

Overview

Build a message client application that connects to Azure Service Bus through a corporate HTTP proxy server. The application should support both authenticated and non-authenticated proxy configurations.

Requirements

Your task is to implement a message client that:

1. Proxy Configuration Support: Accept proxy configuration details (host, port, username, password) and use them to connect to Azure Service Bus
2. WebSocket Transport: Use WebSocket-based transport (typically required for proxy scenarios)
3. Message Operations: Successfully send messages to a queue through the configured proxy

Input

Your application should accept the following configuration:

• Service Bus connection string or namespace details
• Queue name
• Proxy host and port
• Optional proxy username and password (for authenticated proxies)
• Messages to send (list of strings)

Output

The application should:

• Configure the Service Bus client with the provided proxy settings
• Send all provided messages to the specified queue
• Return success/failure status for the operation

Provides messaging capabilities for Azure Service Bus including proxy support for corporate network environments.

Test Cases

Test Case 1: Basic Proxy Configuration @test

Input:

• Proxy host: "proxy.company.com"
• Proxy port: 8080
• Queue name: "test-queue"
• Messages: ["Message 1", "Message 2"]

Expected Behavior: The client should configure proxy settings and successfully connect to Service Bus through the proxy, sending both messages to the queue.

Test Case 2: Authenticated Proxy @test

Input:

• Proxy host: "secure-proxy.company.com"
• Proxy port: 3128
• Proxy username: "proxyuser"
• Proxy password: "proxypass"
• Queue name: "secure-queue"
• Messages: ["Secure message"]

Expected Behavior: The client should configure authenticated proxy settings and successfully send the message through the authenticated proxy connection.

Implementation Notes

• Your implementation should be in a file named proxy_client.py
• Include a test file named test_proxy_client.py with tests that verify proxy configuration
• Handle connection errors gracefully
• The solution should work with both authenticated and non-authenticated proxy servers

Evaluation

Your solution will be evaluated on:

• Correct proxy configuration setup
• Proper use of WebSocket transport
• Successful message transmission through proxy
• Clean code structure and error handling
