Proxy IP with Charles Packet Catchers

Why do ordinary packet capture tools need to be paired with a proxy IP?

Many people who use Charles to analyze network requests often encounter theRequest frequency limitationmaybeUnable to capture data for specific areas. For example, when testing the loading effect of an APP in different geographic regions, the conventional method requires frequent replacement of the physical location, which can simulate the real user's geographic location by simply switching the proxy node in Charles through ipipgo's global residential IP resources.

Two, three steps to complete the Charles agent configuration

In Charles' Proxy Settings settings:

Special note: The ipipgo control panel gets theDynamic residential IPs are automatically rotatedIf you need fixed IP testing, you need to switch to static IP mode in the background in advance.

Third, the special handling of mobile devices to capture packets

When there is a need to capture mobile app data:

1. Configure manual proxy in cellular WiFi settings
2. The server address is the intranet IP of the computer that is running Charles.
3. Nesting ipipgo proxy addresses in Charles' external proxy settings

This ensures that device traffic passes through Charles, but also that the residential IP pools through ipipgo'sReal equipment environment simulationto avoid being recognized by the target server as packet-scraping behavior.

Fourth, the use of dynamic and static IP scenarios

Select the proxy type for ipipgo based on your testing needs:

Special Note: When using HTTPS to capture packets, you need to install the SSL certificate in Charles, and then go to the ipipgo backend to open theFull Protocol Support Mode, otherwise the SSL handshake will fail.

V. Solutions to high-frequency problems

Q: What should I do if Charles shows a proxy connection failure?
A: Check whether the IP authorization whitelist in the background of ipipgo contains the current network export IP, some regions need to be openedTwo-factor authentication lifts geographic restrictionsThe

Q：How to solve the messy code of the captured data?
A：Check "Enable transparent HTTP proxying" in Charles's proxy settings, and make sure that the ipipgo proxy node does not have data compression enabled.

Q: How can I improve the success rate of batch requests?
A: Open in the ipipgo consoleSmart IP Rotation StrategyThe IP address of the export IP is automatically changed every 50 requests, and the quality of individual requests can be checked with Charles' breakpoint debugging function.

By rationalizing the use of ipipgo'sPool of 90 million+ residential IP resourcesWith Charles' traffic analysis capability, developers can accurately restore the user's real network environment and quickly locate interface anomalies. Especially when debugging geographical services, it is recommended to prioritize the use of ipipgo's static residential IP to ensure the stability of the test environment.
