如果您有java.io.InputStream对象,应该如何处理该对象并生成String?
假设我有一个包含文本数据的InputStream,我想将其转换为String,例如,我可以将其写入日志文件。
获取InputStream并将其转换为字符串的最简单方法是什么?
public String convertStreamToString(InputStream is) {
// ???
}

我已经创建了这段代码,并且它有效。没有所需的外部插件。
有一个字符串到流和流到字符串的转换器:
import java.io.ByteArrayInputStream;
import java.io.InputStream;
public class STRINGTOSTREAM {
public static void main(String[] args)
{
String text = "Hello Bhola..!\nMy Name Is Kishan ";
InputStream strm = new ByteArrayInputStream(text.getBytes()); // Convert String to Stream
String data = streamTostring(strm);
System.out.println(data);
}
static String streamTostring(InputStream stream)
{
String data = "";
try
{
StringBuilder stringbuld = new StringBuilder();
int i;
while ((i=stream.read())!=-1)
{
stringbuld.append((char)i);
}
data = stringbuld.toString();
}
catch(Exception e)
{
data = "No data Streamed.";
}
return data;
}

Use:
import java.io.BufferedInputStream;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import java.io.IOException;
public static String readInputStreamAsString(InputStream in)
throws IOException {
BufferedInputStream bis = new BufferedInputStream(in);
ByteArrayOutputStream buf = new ByteArrayOutputStream();
int result = bis.read();
while(result != -1) {
byte b = (byte)result;
buf.write(b);
result = bis.read();
}
return buf.toString();
}
Apache Commons允许:
String myString = IOUtils.toString(myInputStream, "UTF-8");
当然,您可以选择UTF-8以外的其他字符编码。

在Groovy中
inputStream.getText()
InputStream inputStream = null;
BufferedReader bufferedReader = null;
try {
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
String stringBuilder = new StringBuilder();
String content;
while((content = bufferedReader.readLine()) != null){
stringBuilder.append(content);
}
System.out.println("content of file::" + stringBuilder.toString());
}
catch (IOException e) {
e.printStackTrace();
}finally{
if(bufferedReader != null){
try{
bufferedReader.close();
}catch(IoException ex){
ex.printStackTrace();
}
Use:
InputStream in = /* Your InputStream */;
StringBuilder sb = new StringBuilder();
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String read;
while ((read=br.readLine()) != null) {
//System.out.println(read);
sb.append(read);
}
br.close();
return sb.toString();
