Profiler

Profiler is a lightweight Go application that works as a reverse proxy to profile incoming HTTP requests and save the request information to a file in JSON format.

Features

• Profile incoming HTTP requests.
• Save request information to a file in JSON format.
• Works as a reverse proxy to forward requests to the target server.
• Extracts information such as method, URL, headers, IP, browser, and timestamp.
• Configurable using a .env file.

Getting Started

Prerequisites

• Go 1.16 or higher.

Installation

1. Clone the repository:

git clone https://github.com/yourusername/profiler.git

2. Change to the repository's directory

cd profiler

3.Build the application

go build

Configuration

Create a .env file in the repository's directory with the following content:

PORT=8080
OUT_FILE="profile.json"
OUT_FORMAT="JSON"
TARGET_SERVER="http://localhost:50133"

Adjust the values as needed:

• PORT: The port on which the Profiler server will listen.
• OUT_FILE: The path to the output file where request information will be saved.
• OUT_FORMAT: The format in which request information will be saved. Currently, only "JSON" is supported.
• TARGET_SERVER: The URL of the target server to which requests will be forwarded.

Running the Profiler

./profiler config.env

Usage

Send an HTTP request to the Profiler server at http://localhost:PORT/your-path. The server will profile the request and save the information to the specified output file, then forward the request to the target server.
