java - 如何在java中使用HTTP url获取远程服务器目录的所有文件名？

Question

我想通过 http URL 访问所有文件(名称)。 前任。 http://app.examle.com/csv/ 所以我需要评估 csv 文件中存在的所有文件(名称)

     headerBaseUrl="http://app.examle.com/csv/stock.csv";
    URL br = new URL(headerBaseUrl);
        bufferedReader = new BufferedReader(
                new InputStreamReader(br.openStream()));
        // Create List for holding Employee objects
        List<BranchWiseStock> branchWiseStock = new ArrayList<BranchWiseStock>();

        String line = "";
        // Read to skip the header
        bufferedReader.readLine();
        // Reading from the second line
        while ((line = bufferedReader.readLine()) != null) {
            String[] stockDetails = line.split(COMMA_DELIMITER);
            if (stockDetails.length > 0) {
                    System.out.println(" data "+stockDetails);
              }
            }

在这里我可以轻松获取1个文件的数据 但我想读取多个文件 请帮助我...!
