How to Add Authorization in Swagger UI
Adding authorization to your Swagger UI documentation is crucial for ensuring that only authenticated users can access sensitive endpoints. In this article, we will guide you through the process of adding authorization to your Swagger UI application. By following these steps, you will be able to protect your API endpoints and maintain the security of your data.
1. Choose an Authorization Type
Before adding authorization to your Swagger UI, you need to decide on the type of authorization you want to implement. There are several methods to choose from, such as Basic Authentication, OAuth 2.0, API Key, and JWT (JSON Web Tokens). Each method has its own set of advantages and use cases, so select the one that best fits your requirements.
2. Configure the Swagger UI
Once you have chosen the authorization type, you need to configure your Swagger UI application accordingly. This involves modifying the Swagger UI configuration file, which is typically located at `path/to/swagger-ui/dist/swagger-ui.js`. Here’s how to do it for the most common authorization types:
2.1 Basic Authentication
To add Basic Authentication, add the following code to the `config` object in the Swagger UI configuration file:
“`javascript
config = {
// … other configurations …
authorizations: {
basicAuth: {
type: ‘basic’
}
},
// … other configurations …
}
“`
2.2 OAuth 2.0
For OAuth 2.0, you need to define the authorization URL and token URL in the `config` object:
“`javascript
config = {
// … other configurations …
authorizations: {
oauth2: {
name: ‘oauth2’,
type: ‘oauth2’,
flows: {
authorizationCode: {
authorizationUrl: ‘https://example.com/oauth/authorize’,
tokenUrl: ‘https://example.com/oauth/token’,
scopes: [‘read’, ‘write’]
}
}
}
},
// … other configurations …
}
“`
2.3 API Key
To add API Key authorization, you can use the following configuration:
“`javascript
config = {
// … other configurations …
authorizations: {
apiKeyAuth: {
type: ‘apiKey’,
name: ‘apiKey’,
in: ‘header’
}
},
// … other configurations …
}
“`
2.4 JWT
For JWT authorization, you can use the following configuration:
“`javascript
config = {
// … other configurations …
authorizations: {
jwt: {
type: ‘apiKey’,
name: ‘Authorization’,
in: ‘header’
}
},
// … other configurations …
}
“`
3. Implement the Authorization in Your API
After configuring the Swagger UI, you need to implement the chosen authorization method in your API backend. This involves setting up the necessary endpoints and logic to handle authentication and authorization requests. Make sure to refer to the documentation of the authorization method you have chosen for detailed instructions.
4. Test Your Configuration
Once you have implemented the authorization in your API and Swagger UI, it’s essential to test your configuration. Access your Swagger UI application and try to access protected endpoints to ensure that the authorization is working as expected. If you encounter any issues, review your configuration and API implementation to identify and resolve the problem.
By following these steps, you can successfully add authorization to your Swagger UI application and protect your API endpoints from unauthorized access. Remember to choose the appropriate authorization method and implement it correctly to maintain the security of your data.
