Java InputStream 转 String：高效代码示例与解析

{"title":"Java InputStream 转 String：高效代码示例与解析","description":"本文提供详细的Java代码示例，教你如何将InputStream转换为String，并解释代码原理，以及BufferedReader和InputStreamReader的使用方法。","keywords":"Java, InputStream, String, 转换, 代码示例, BufferedReader, InputStreamReader, IO流","content":""要将InputStream转为String，可以使用Java的IO流操作。以下是一个示例代码：\n\njava\\nimport java.io.BufferedReader;\\nimport java.io.IOException;\\nimport java.io.InputStream;\\nimport java.io.InputStreamReader;\\n\\npublic class InputStreamToString {\\n\\n public static void main(String[] args) {\\n InputStream inputStream = // 获取输入流，可以是文件、网络连接等\\n\\n String result = convertToString(inputStream);\\n System.out.println(result);\\n }\\n\\n public static String convertToString(InputStream inputStream) {\\n BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));\\n StringBuilder stringBuilder = new StringBuilder();\\n String line;\\n try {\\n while ((line = reader.readLine()) != null) {\\n stringBuilder.append(line);\\n }\\n } catch (IOException e) {\\n e.printStackTrace();\\n } finally {\\n try {\\n inputStream.close();\\n reader.close();\\n } catch (IOException e) {\\n e.printStackTrace();\\n }\\n }\\n return stringBuilder.toString();\\n }\\n}\\n\n\n在上面的示例中，我们使用了BufferedReader和InputStreamReader来读取InputStream的内容，并将其逐行追加到StringBuilder中。最后，通过toString()方法将StringBuilder转换为String并返回。"}
