Httptap
httptap 是一款网络工具，用于拦截系统级数据包并监控 Linux 进程的 HTTP 和 HTTPS 流量。它作为一个网络数据包嗅探器和流量监视器，旨在捕获并显示本地应用发送的实时请求和响应。
该项目包括一个本地流量重定向器，将远程主机名或 IP 地址映射到 localhost 以进行服务测试。为了支持详细检查，它具有用于解密 HTTPS 流量的 TLS 终止代理，以及一个 HAR 文件导出器，将捕获的数据转储为标准的 HTTP Archive 格式以供外部分析。
该工具的技术功能涵盖使用 eBPF 的内核级数据包捕获、透明代理拦截和进程特定流量过滤。它还提供本地 DNS 重定向以覆盖系统名称解析。
Features
- HTTP Traffic Inspection - Provides real-time monitoring and inspection of HTTP and HTTPS requests and responses sent by Linux processes.
- Network Communication Debugging - Observes the outbound web communication of running programs to identify API errors or unexpected behavior.
- Real-Time Traffic Dashboards - Captures and displays HTTP and HTTPS requests and responses made by a specific process in real time.
- Packet Capture Implementations - Implements high-performance packet interception at the kernel level using eBPF programs.
- Process-Level Filters - Isolates network packets by matching kernel-level process identifiers to filter traffic from a single target application.
- Transparent Network Proxies - Reroutes outbound network traffic through a local listener without requiring client-side configuration changes.
- SSL/TLS Termination - Decrypts HTTPS traffic by acting as a proxy that terminates encrypted connections for inspection.
- Packet-Sniffing Analyzers - Intercepts network traffic at the packet level to analyze data sent by local applications.
- Local Redirection Rules - Routes network traffic from remote hostnames or IP addresses to a local machine for testing.
- Local DNS Mapping - Overrides system name resolution to map remote hostnames to local IP addresses for testing.
- Localhost Domain Mappings - Maps specific hostnames or IP addresses to the local machine to enable communication with local services.
- Local Service Address Mapping - Maps remote hostnames or IP addresses to localhost for local service testing.
- HAR File Exporters - Dumps intercepted network traffic into the standardized HTTP Archive format for external analysis.
- Network Traffic Analyzers - Exports captured web requests into HAR files for visualization and analysis in external tools.
- HAR Serialization - Formats captured request and response metadata into standardized HAR JSON structures for external analysis tools.
