如何将ZipInputStream转换为InputStream?
我有将ZipInputSream转换为byte []的代码,但我不知道如何将其转换为inputstream。
private void convertStream(String encoding, ZipInputStream in) throws IOException, UnsupportedEncodingException
{
final int BUFFER = 1;
@SuppressWarnings("unused")
int count = 0;
byte data[] = new byte[BUFFER];
while ((count = in.read(data, 0, BUFFER)) != -1)
{
// How can I convert data to InputStream here ?
}
}
回答:
这是我解决此问题的方法。现在,我可以将单个文件从ZipInputStream作为InputStream传输到内存。
private InputStream convertZipInputStreamToInputStream(ZipInputStream in, ZipEntry entry, String encoding) throws IOException{
final int BUFFER = 2048;
int count = 0;
byte data[] = new byte[BUFFER];
ByteArrayOutputStream out = new ByteArrayOutputStream();
while ((count = in.read(data, 0, BUFFER)) != -1) {
out.write(data);
}
InputStream is = new ByteArrayInputStream(out.toByteArray());
return is;
}
