Authz is an authorization middleware for [Gin](https://github.com/gin-gonic/gin), it's based on [https://github.com/casbin/casbin](https://github.com/casbin/casbin).

## Installation

```bash

go get github.com/gin-contrib/authz

```

## Simple Example

```Go

package main

import (

  "net/http"

  "github.com/casbin/casbin/v2"

  "github.com/gin-contrib/authz"

  "github.com/gin-gonic/gin"

)

func main() {

  // load the casbin model and policy from files, database is also supported.

  e := casbin.NewEnforcer("authz_model.conf", "authz_policy.csv")

  // define your router, and use the Casbin authz middleware.

  // the access that is denied by authz will return HTTP 403 error.

  router := gin.New()

  router.Use(authz.NewAuthorizer(e))

}

```

## Documentation

The authorization determines a request based on ``{subject, object, action}``, which means what ``subject`` can perform what ``action`` on what ``object``. In this plugin, the meanings are:

1. ``subject``: the logged-on user name

2. ``object``: the URL path for the web resource like "dataset1/item1"

3. ``action``: HTTP method like GET, POST, PUT, DELETE, or the high-level actions you defined like "read-file", "write-blog"

For how to write authorization policy and other details, please refer to [the Casbin's documentation](https://github.com/casbin/casbin).
