我有下面的函数，我用webClient调用了一个API，该API有两个参数
此函数工作良好

public Mono<PersonContent> searchPerson(KRequest keyword, int page, int size) {
    return webClient.post().uri(spiProperties.getUrl().getK().getUrlPersons() + "search?page=" + page + "&size=" + size)
            .bodyValue(keyword)
            .retrieve()
            .bodyToMono(PersonContent.class);
}

当我使用queryParams设置如下参数时，我遇到了一个异常
java.net.UnknownHostException: Unknown host (https:)

public Mono<PersonContent> searchPerson(KRequest keyword, int page, int size) {
    final MultiValueMap<String, String> queryParams = new LinkedMultiValueMap<>();
    queryParams.add("page", String.valueOf(page));
    queryParams.add("size", String.valueOf(size));

    return webClient.post().uri(
                    uriBuilder -> uriBuilder
                            .path(spiProperties.getUrl().getK().getUrlPersons() + "search")
                            .queryParams(queryParams)
                            .build())
            .bodyValue(keyword)
            .retrieve()
            .bodyToMono(PersonContent.class);
}
