How do I set up OAuth2.0 Request Headers

[hero-zhanghao]

I wanted to put a value, like postman, on the SpringDoc Swagger page, and apply it to all requests.

And swagger is not expected to pop up an input popup for user names and passwords.

Thanks for all the answers.

You should set up flows for OAuth 2, which you will use.
I guess, I want to use Password Flow

In your configuration:

1. This helps you to authorize by Password Flow in SwaggerUI

@Bean
public OpenAPI openAPI() {
	return new OpenAPI()
		....
                .components(getComponents())
		.info(new Info())
		.addSecurityItem(new SecurityRequirement().addList("Password Flow"));
}

private Components getComponents() {
		SecurityScheme passwordFlowScheme = new SecurityScheme()
				.type(SecurityScheme.Type.OAUTH2)
				.flows(new OAuthFlows()
						.password(
								new OAuthFlow()
										.tokenUrl("http://localhost:8080/oauth/token")
										.scopes(new Scopes().addString("trust", "trust all"))
						)
				);

		return new Components()
				.securitySchemes(Map.of("Password Flow", passwordFlowScheme));
}

2. This helps you to attach Access Token to you requests. This is useful, when you already have an access token and want to attach it only.

@Bean
public OpenAPI openAPI() {
	return new OpenAPI()
		....
                .components(getComponents())
		.info(new Info())
		.addSecurityItem(new SecurityRequirement().addList("Access Token"));
}

private Components getComponents() {
		SecurityScheme authorizationHeaderSchema = new SecurityScheme()
				.name("Authorization")
				.type(SecurityScheme.Type.APIKEY)
				.in(SecurityScheme.In.HEADER);

		return new Components()
				.securitySchemes(Map.of("Access Token", authorizationHeaderSchema));
}

You can combine the methods and inject some others.
