scala連接elasticsearch並完成基本認證

def getRestClient(url: String): RestClient = {
      val restClientBuilder = RestClient.builder(HttpHost.create(url))
        val provider = new BasicCredentialsProvider()
        provider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("user", "password"))
        restClientBuilder.setHttpClientConfigCallback((httpClientBuilder: HttpAsyncClientBuilder) => {
          httpClientBuilder.disableAuthCaching()
          httpClientBuilder.setDefaultCredentialsProvider(provider)
        })
      val restClient = restClientBuilder.build()
      restClient
    }
