使用Apache Commons进行base64字符串解码

Question

I am trying to decode one of my files from dropbox. Using one of the post in this forum

import org.apache.commons.codec.binary.Base64;
import org.apache.commons.codec.binary.StringUtils;
String base64String = getFileResults.get_Response();//returns a file content in base64
String result = StringUtils.newStringUtf8(Base64.decodeBase64(base64String));

But the Netbeans keeps telling me that the decodeBase64() does not take string, but the API says that it takes a string in base 64.

What am i missing?

Answer 1

尝试Java SE中可用的javax.xml.bind.DatatypeConverter.parseBase64Binary(base64String) 。

Answer 2

import org.apache.commons.codec.binary.Base64;
import org.apache.commons.io.FileUtils;

...
File file = new File( "path" );
byte[] bytes = Base64.decodeBase64( "base64" );
FileUtils.writeByteArrayToFile( file, bytes );
