将InputStream读取为UTF-8 [英] Reading InputStream as UTF-8

问题描述

我正试图通过互联网逐行读取 text / plain 文件。我现在的代码是：

I'm trying to read from a text/plain file over the internet, line-by-line. The code I have right now is:

URL url = new URL("http://kuehldesign.net/test.txt");
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
LinkedList<String> lines = new LinkedList();
String readLine;

while ((readLine = in.readLine()) != null) {
    lines.add(readLine);
}

for (String line : lines) {
    out.println("> " + line);
}

文件 test.txt ，包含¡Hélló！，我正在使用它来测试编码。

The file, test.txt, contains ¡Hélló!, which I am using in order to test the encoding.

当我查看 OutputStream （ out ），我将其视为> ¬°H√©ll√≥！。我不相信这是 OutputStream 的问题，因为我可以做 out.println（é）; 没有问题。

When I review the OutputStream (out), I see it as > ¡Hélló!. I don't believe this is a problem with the OutputStream since I can do out.println("é"); without problems.

任何读取的想法都将形成 InputStream 作为UTF-8？谢谢！

Any ideas for reading form the InputStream as UTF-8? Thanks!

推荐答案

解决了我自己的问题。这一行：

Solved my own problem. This line:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

需要：

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));

或自Java 7以来：

or since Java 7:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));
