There are many encoding challenges when it comes to creating URIs. For more flexibility while still being right on the encoding part, WebClientprovides a builder-based variant for the URI:
在创建 URI 时存在许多编码挑战。为了在编码部分仍然正确的同时获得更大的灵活性，WebClient为 URI 提供了一个基于构建器的变体：
WebClient.create().get()
.uri(builder -> builder.scheme("http")
.host("example.org").path("save")
.queryParam("name", "spring-framework")
.build())
.retrieve()
.bodyToMono(String.class);

webClient.get()
.uri(uriBuilder -> uriBuilder.path("/user/repos")
.queryParam("sort", "updated")
.queryParam("direction", "desc")
.build())
.header("Authorization", "Basic " + Base64Utils
.encodeToString((username + ":" + token).getBytes(UTF_8)))
.retrieve()
.bodyToFlux(GithubRepo.class);
