HTTP-server-with-auth# HTTP Server With Authentication

Introduction

You are to use gin framework package and concurrency in golang and jwt-go to implement a simple http server. You should implement an rest api with authentication on some endpoints to upload or download a file. All registered users can upload and download files. no user can download other user's files. users can give access to other specific users to download their files. REST APIs that you should implement are listed below:

localhost:8080/register

1. json :

   {
      "username" : "string",
      "password" : "string"
   }

   create new user

localhost:8080/login

1. json :

   {
      "username" : "string",
      "password" : "string"
   }

   logins and gives access token

localhost:8080/uploadFile with auth

input formats :

1. form :

     file : []byte
   

   In this format, file is a byte array of the actual file. uploads file in filesystem.

output format :

1. json :

   successful upload :

    {
        "download_url" : "string"
    }

   download_url is the path of saved file in filesystem.

   failure upload :

    {
        "error" : "string"
    }

   error is a description of the occurred error.

localhost:8080/downloadFile with auth

1. json :

    {
        "download_url" : "string"
    }

   In this format, download_url is an id that we got in successful upload request. it will download the file if user has download premission.

output format :

1. json :

   successful download :

     http response with actual file
   

   
   failure download :

    {
        "error" : "string"
    }

   error is a description of the occurred error.

localhost:8080/addPremission with auth

1. json :

    {
        "download_url" : "string",
        "user_to_be_add" : "string"
    }
