Packet capture helper function

Real-time packet capture

Supports real-time capture of HTTP/HTTPS traffic, and can view detailed data of requests and responses, including headers, status codes and other information.

Supports original text, JSON, XML, HTML and other format switching to meet the debugging needs of different scenarios.

Data import and export

Allows exporting captured data to local files for easy sharing or subsequent analysis.

Supports direct import of externally captured Har files to achieve cross-platform data compatibility.

Custom capture rules

Bypass mode: Filter specific domain name traffic to avoid interference from irrelevant data.

Interception mode: Accurately capture specified domain name traffic to facilitate in-depth analysis of specific applications or services.

Smart filtering and searching

Quickly locate problems through keyword search and URL filtering.

Supports filtering results by content type (such as JSON, HTML, XML, images or videos) to improve analysis efficiency.

Privacy protection

All traffic data is processed locally, and self-signed certificates are generated on the device to ensure data security and users are always in control of their data.

Frequently Asked Questions about Packet Capture Helper

Unable to catch package or no request record

Possible reasons:

Non-HTTP/HTTPS protocol: App uses QUIC, Spdy and other underlying protocols or custom protocols to communicate, regardless of system proxy settings.

Proxy-less mode: Proxy.NO_PROXY is configured in the App code, bypassing the system proxy and sending the package directly.

SSL Pinning certificate locking: The built-in app only accepts certificates for specified domain names and rejects middleman certificates from packet capture tools.
