Uploading and Downloading Binary Files
Explore how to implement uploading and downloading of binary files in Go using REST APIs. Understand file storage on the local filesystem, secure handling of uploads, and efficient file serving. Gain practical experience by running example code that supports client-server file exchanges.
We'll cover the following...
It is not unusual to need to store binary files in a RESTful server and being able to download them afterward—for example, for developing photo libraries or document libraries. This lesson illustrates how to implement that functionality.
Coding example
For reasons of simplicity, the example is going to be included in the Educative-Content/rest-api GitHub repository used earlier for implementing the RESTful server. For this lesson, we are going to be using the file directory to store the relevant code, which is saved as binary.go. In reality, binary.go is a small RESTful server that only supports the uploading and downloading of binary files through the /files/ endpoint.
There exist three main ways to save the files we upload:
On the local filesystem
On a database management system that supports the storing ...
