How does the Dynamic IP Proxy adapt to the Postman interface testing tool?

Hands-on with dynamic IP to accelerate Postman interface test

Recently found that many test engineers in the use of Postman interface debugging, often encountered too high a request frequency is limited. This time the dynamic IP proxy can come in handy, today specifically about how to ipipgo's dynamic residential IP and Postman used in conjunction.

Why do I need a dynamic IP for Postman?

To cite a real case: an e-commerce platform development needs to test the product details interface in bulk, using a fixed IP to send requests continuously, in less than 10 minutes the server pulled the black. After switching to ipipgo's dynamic residential IP, the system automatically switched to real home networks in different regions and successfully completed 5000 stress tests.

dynamic IPReal-time replacement of featuresIt can effectively avoid being recognized as machine traffic by the target server. Especially when it is necessary to test the service response of different regions, ipipgo covers a resource pool of more than 240 countries, which can accurately simulate the access of real users from all over the world.

Postman Proxy Configuration in Three Steps

1. Open the Postman settings panel and find theSettings - Proxy

2. In the Global Proxy Configuration field select theHTTP/HTTPSpact

3. Fill in the proxy information obtained from ipipgo:

proxy server: gateway.ipipgo.net

port number: Fill in according to the type of package purchased (visible in the console)

Authentication Methods: User name + password combination authentication

Key reminder: remember to generate the ipipgo backend in theDynamic IP WhitelistingIt is recommended to enable the automatic switching function and set the IP address to change every 50 requests. This ensures test continuity and avoids triggering the wind control mechanism.

Five details of optimization in the real world

1. geo-directed testing: in ipipgo console to select a specific city node, such as the need to test the Shanghai server room interface, fixed allocation of Shanghai residential IP

2. protocol adaptation skills: according to the interface type flexible switching HTTP/SOCKS5 proxy, encounter complex encryption interface recommended the use of ipipgoFull Protocol Supportfunctionality

3. Request header camouflage: with dynamic IP to set up a random User-Agent, Postman's Pre-request Script can be automatically generated

4. Abnormal retry mechanism: add status code judgment in Tests script, when encountered 403/429 automatically replace the proxy IP

5. Traffic statistics: use ipipgo's usage monitoring panel to view IP consumption of different projects in real time

Frequently Asked Questions First Aid Guide

Q：Postman prompts connection timeout after configuring proxy?

A: First check whether the proxy address contains the protocol header (error example: http://gateway.ipipgo.net), the correct one should only fill in the domain name without adding the protocol

Q: Some HTTPS interfaces return certificate errors?

A: Turn off "SSL certificate verification" in Postman's Proxy settings, and make sure you are using ipipgo's encrypted tunnel.

Q: How do I verify if the IP has been successfully changed?

A: Add code to Pre-request Script:

pm.sendRequest('https://ip.ipipgo.net', function (err, res) {

console.log('Current IP:' + res.json().ip);

});

Why choose ipipgo?

After comparing multiple vendors, ipipgo'sResidential IP PurityIt does have an advantage. Their IP resources come from real home broadband, unlike server room IPs which are easily recognized. Especially when high concurrency testing is required, dynamic IP pools of90M+ Resource ReserveDon't worry about IP depletion at all.

They recently addedIntelligent RoutingThe function can automatically match the optimal node according to the location of the target server. When we tested the overseas interface last week, the original 200ms response was directly reduced to 80ms, and the effect was immediate.

It is recommended that students who are just starting out practice with free test resources first, familiar with the entire agent configuration process and then on the formal environment. As long as you master the correct configuration method, dynamic IP can definitely enhance your interface testing efficiency by several orders of magnitude.
