这部分代码的逻辑可以优化，并且存在一个潜在问题。

  1. 可读性: config.getRerankConfig() 被多次调用。可以将其结果存储在一个局部变量中，以提高代码的可读性和效率。
  2. 潜在错误: if (!rerankingModel.isEmpty()) 这个判断条件可能会导致一个问题。如果用户设置了 enableRerank(true) 并提供了一个空的 rerankConfig（例如 RerankConfig.builder().build()），其意图很可能是使用 Dify 的默认重排模型。但当前代码会因为 rerankingModel 为空而不会将 reranking_model 字段加入到请求中，这可能与预期行为不符。移除这个判断可以确保即使 reranking_model 为空对象 {} 也会被发送，从而让 Dify 服务端来决定如何处理（通常是使用默认值）。

建议进行如下修改，以提高代码的健壮性和可读性。

                        if (config.getRerankConfig() != null) {
                            RerankConfig rerankConfig = config.getRerankConfig();
                            Map<String, Object> rerankingModel = new HashMap<>();
                            if (rerankConfig.getProviderName() != null) {
                                rerankingModel.put(
                                        "reranking_provider_name",
                                        rerankConfig.getProviderName());
                            }
                            if (rerankConfig.getModelName() != null) {
                                rerankingModel.put(
                                        "reranking_model_name",
                                        rerankConfig.getModelName());
                            }
                            retrievalModel.put("reranking_model", rerankingModel);
                        }
