java - 如何以 Java 8 方式获取特定 URL 上的文本行流？

Question

我想逐行阅读这些词:http://www.puzzlers.org/pub/wordlists/unixdict.txt

我尝试获取流:

Stream<String> stream = Files.lines(Paths.get("http://www.puzzlers.org/pub/wordlists/unixdict.txt"));
stream.forEach((word) -> System.out.println(word));
//Close the stream and it's underlying file as well
stream.close();

但我怀疑它只适用于文件。是否有类似的 URL 方法？

Answer 1

BufferedReader 还有一个返回流的 lines() 方法。所以你只需要打开一个 BufferedReader 包装一个 InputStreamReader 包装 URL 连接输入流:

try (InputStream is = new URL("http://www.puzzlers.org/pub/wordlists/unixdict.txt").openConnection().getInputStream();
     BufferedReader reader = new BufferedReader(new InputStreamReader(is));
     Stream<String> stream = reader.lines()) {
    stream.forEach(System.out::println);
}
