# Authenticated request

In this guide you will see how you can request the API as an authenticated user.

# Introduction

To show you many of the concepts on the roles and permissions part, we will use many users and roles.

After that we will see the authentication workflow to get a JWT and use it for an API request.

We will have one group of users that will be able to only fetch Articles and an other group that will be able to fetch, create and update Articles.

# Setup

# Create Content Type

Lets create a new Content Type Article

  • Click on Content-Types Builder in the left menu
  • Then + Create new content-type
  • Fill Display name with article
  • Create 2 fields
    • Text short named title
    • Rich text named content
  • And save this new Content Type

Then create some Articles from the Content Manager.

# Create Roles & Permissions

We will create 2 new groups to manage available actions for different kind of users.

  • Click on Settings in the left menu
  • Select the Roles under USERS & PERMISSIONS PLUGIN section
  • Then + Add New Role
  • Fill name with Author
  • Check Select All for the Application Article Content Type.
  • And save the new role

And repeat the operation for the Reader group and check find, findOne and count.

# Create users

Finally create 2 users with the following data.

User 1

  • username: author
  • email: author@strapi.io
  • password: strapi
  • role: Author

User 2

  • username: reader
  • email: reader@strapi.io
  • password: strapi
  • role: Reader

# Login as a Reader

To login as a user, you will need to follow the login documentation.

Here is the API route for the authentication /auth/local.

You have to request it in POST.

The API response contains the user's JWT in the jwt key.

{
    "jwt": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwiaWF0IjoxNTc2OTM4MTUwLCJleHAiOjE1Nzk1MzAxNTB9.UgsjjXkAZ-anD257BF7y1hbjuY3ogNceKfTAQtzDEsU",
    "user": {
        "id": 1,
        "username": "reader",
        ...
    }
}

You will have to store this JWT in your application, it's important because you will have to use it the next requests.

# Fetch articles

Let's fetch Articles you created.

To do so, you will have to fetch /articles route in GET.

import axios from 'axios';

const { data } = await axios.get('http://localhost:1337/articles');

console.log(data);

Here you should receive a 403 error because you are not allowed, as Public user, to access to the articles.

You should use the JWT in the request to say that you can access to this data as Reader user.

import axios from 'axios';

const { data } = await axios.get('http://localhost:1337/articles', {
  headers: {
    Authorization:
      'Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwiaWF0IjoxNTc2OTM4MTUwLCJleHAiOjE1Nzk1MzAxNTB9.UgsjjXkAZ-anD257BF7y1hbjuY3ogNceKfTAQtzDEsU',
  },
});

console.log(data);

And tada you have access to the data.

# Create an Article

To do so, you will have to request the /articles route in POST.

import axios from 'axios';

const { data } = await axios.post(
      'http://localhost:1337/articles',
      {
        title: 'my article',
        content: 'my super article content',
      },
      {
        headers: {
          Authorization:
            'Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwiaWF0IjoxNTc2OTM4MTUwLCJleHAiOjE1Nzk1MzAxNTB9.UgsjjXkAZ-anD257BF7y1hbjuY3ogNceKfTAQtzDEsU',
        },
      }
    );

    console.log(data);

If you request this as a Reader user, you will receive a 403 error. It's because the Reader role does not have access to the create function of the Article Content Type.

To fix that you will have to login with the Author user and use its JWT into the request to create an Article.

With that done, you will be able to create an Article.
