它使用以下堆栈跟踪引发以下错误：

正在命中的URI被列为https://grmim-cloud-sec-honeycomb-develop.np.uscm.libertyec.com/grmimcld-security-api-v0/userpermission

它似乎是一个绝对URI。

不确定为什么要抛出此错误。

下面是用于发出请求的函数的一部分：

        String userPermissionsEndpoint = cloudSecurityAPIURL + "/grmimcld-security-api-v0/userpermission";

        Flux<String> body = Flux.just("{\"pin\" : \"" + user + "\"}");

        BodyInserter<Flux<String>, ReactiveHttpOutputMessage> bodyInserter = BodyInserters.fromPublisher(body, String.class);

        String cloudSecurityResponse = this.webClient

http://localhost:8888/grmimcld-security-api-v0/default看起来是对的。在内部，它可能正在调用其他URL。因此，例如，它可能正在调用oauth令牌端点。

您可以在下面的行中添加调试点，以查找导致失败的实际URL路径。
