Large File Streaming in Go over HTTP

This is a simple Go project that demonstrates how to send and receive files using Go. The project has two modes: CLI and HTTP.

Getting Started

Prerequisites

• Go (version 1.16 or higher)

Installation

1. Initialize the Go module:

   go mod init file_handler

2. Download the dependencies:

   go mod tidy

Running the Project

2. CLI Mode:

• Flags are used to choose between sending and receiving (mode flag).
• If the file flag is provided, the program sends the specified file.
• If no file is specified, the server starts and listens for incoming files.

3. HTTP Mode:

• The Gin framework is used to handle POST requests at the /upload endpoint.
• Files are uploaded using multipart form data and saved to the specified directory.

How to Run:

CLI Mode:

• Start the server to receive files:

  go run main.go --mode cli --save-dir /path/to/save
• Send a file:

  go run main.go --mode cli --file /path/to/demo.mp4 --address 0.0.0.0:8080

HTTP Mode:

• Start the HTTP server:

  go run main.go --mode http --save-dir /path/to/save
• Upload a file via HTTP POST:

  curl -X POST -F "file=@/path/to/demo.mp4" http://0.0.0.0:8080/upload

Building the Project

To build the project, use the following command:

go build -o file_handler main.go
