1、InputStream转化为String 1.1 JDK原生提供 方法一: byte[] bytes = new byte[0]; bytes = new byte[inputStream.available()]; inputStream.read(bytes); String str = new String(bytes); 方法二: String result = new BufferedReader(new InputStreamReader(inputStream)) .lines().collect(Collectors....

1、String –> InputStream InputStrem is = new ByteArrayInputStream(str.getBytes()); or ByteArrayInputStream stream = new ByteArrayInputStream(str.getBytes()); 2、InputStream–>String inputStream input; StringBuffer out = new StringBuffer(); byte[] b = new byte[4096]; for (int n; (n...
可以使用ByteArrayInputStream等类来实现。 // 创建InputStream对象InputStreaminputStream=newByteArrayInputStream(buffer); 1. 2. 至此,我们已经成功将String转换为InputStream。 4. 类图 下面是InputStream与String相互转换的类图表示: InputStream+read() : intFileInputStream..ByteArrayInputStream..String+getBytes...
