InputStream与String 转换

转自：http://wesker0918.iteye.com/blog/286642和http://www.oschina.net/code/snippet_54371_3138两处

String --> InputStream

1. InputStream StringToInputStream(String str){  
2.     ByteArrayInputStream stream = new ByteArrayInputStream(str.getBytes());  
3.     return stream;  
4. } 
   

InputStream --> String

1. String inputStreamToString(InputStream is){  
2.     BufferedReader in = new BufferedReader(new InputStreamReader(is));  
3.     StringBuffer buffer = new StringBuffer();  
4.     String line = "";  
5.     while ((line = in.readLine()) != null){  
6.         buffer.append(line);  
7.     }  
8.     return buffer.toString();  
9. }

int i = -1;//org.apache.commons.io.output.ByteArrayOutputStreamByteArrayOutputStream baos = new ByteArrayOutputStream();while ((i = is.read()) != -1) {baos.write(i);}String content = baos.toString();
int i = -1;byte[] b = new byte[1024];StringBuffer sb = new StringBuffer();while ((i = is.read(b)) != -1) {sb.append(new String(b, 0, i));}String content = sb.toString();
