In addition to WebClient, Spring 5 includes WebTestClient, which provides an interface extremely similar to WebClient, but designed for convenient testing of server endpoints.. We can set this up either by creating a WebTestClient that's bound to a server and sending real requests over HTTP, or one that's bound to a single Controller, RouterFunction or . How can I do this? Hello all, I have an Oauth2 authentication service that must use proxy to call the OAuth provider to get token after user authentication. In this tutorial, we are going to show how to customize Spring's WebClient - a reactive HTTP client - to log requests and responses. Using ExchangeFilterFunctions.

There is a specific issue with Spring Security and Spring WebFlux's WebClient in general, where it is not that easy to understand how to pass the authentication from the Spring Framework MVC controller directly into WebClient, if the project does not use OAuth2Authentication, and when the Spring Security is configured so that the endpoints must require authority (ROLE_ etc. The 407 Proxy Authentication Required is an HTTP response status code indicating that the server is unable to complete the request because the client lacks proper authentication credentials for a proxy server that is intercepting the request between the client and server. To better understand the role of the OAuth2 Client, we can also use our own servers, with an implementation available here. Now, on the application page, click on Generate a new client secret.
