What tools did you use for working with HTTP?

I actively used the following tools for working with HTTP:

• Postman / Insomnia: For manual API testing, sending requests (GET, POST, PUT, DELETE, etc.), checking responses, managing environments and request collections. Convenient for debugging and documentation.
• curl: In the command line for quick HTTP requests, endpoint testing, and automation. Useful for checking resource availability and simple interactions.
• Fiddler / Charles Proxy: Proxy tools for intercepting, viewing, modifying, and analyzing HTTP/HTTPS traffic between client and server. Necessary for deep analysis of application behavior and debugging issues.
• Browser developer tools (Chrome DevTools, Firefox Developer Edition): The "Network" tab for monitoring all HTTP requests and responses initiated by the page, analyzing headers, content, and performance.
• Libraries for automation testing:
  • Python: requests for sending HTTP requests within automated API tests.

    # python
    import requests
    
    url = "http://example.com/api/resource"
    response = requests.get(url)
    # Check response status and content
    assert response.status_code == 200
    print(response.json())
    

  • Java: Apache HttpClient or OkHttp for similar purposes in test frameworks like TestNG or JUnit.

    // java
    import org.apache.http.client.methods.HttpGet;
    import org.apache.http.impl.client.CloseableHttpClient;
    import org.apache.http.impl.client.HttpClients;
    
    // Example GET request
    try (CloseableHttpClient client = HttpClients.createDefault()) {
        HttpGet request = new HttpGet("http://example.com/api/resource");
        // Execute request and handle response
    } catch (Exception e) {
        e.printStackTrace();
    }
    

  • JavaScript (Node.js): axios or built-in fetch for testing backend services.

    // javascript
    const axios = require('axios');
    
    async function fetchData() {
        try {
            const response = await axios.get('http://example.com/api/resource');
            console.log(response.data);
        } catch (error) {
            console.error(error);
        }
    }
    fetchData();
    

The choice of tool depended on the task: manual testing, traffic analysis, writing automated tests, or quick debugging in the command line.
