推荐答案

Tikam完成后，尝试使用这个类，

Tikam done, try to use this class,

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;
import java.io.StringWriter;
import java.io.Writer;



    /**
     * 
     * @author JSR
     *
     */

 public class StreamUtils {

/**
 * A helper method to convert an InputStream into a String
 * @param inputStream
 * @return the String or a blank string if the IS was null
 * @throws IOException
 */
public static String convertToString(InputStream inputStream) throws IOException {
    if (inputStream != null) {
        Writer writer = new StringWriter();

        char[] buffer = new char[1024];
        try {
            Reader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 1024);
            int n;
            while ((n = reader.read(buffer)) != -1) {
                writer.write(buffer, 0, n);
            }
        } finally {
            inputStream.close();
        }
        return writer.toString();
    } else {
        return "";
    }
}
 }
