跟据HttpRequest获取body内数据

1 . 字节流

 

InputStream inputStream = null ;
try {
 inputStream = request.getInputStream();
 BufferedInputStream byteOutputStream = new BufferedInputStream( inputStream );
 ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
 byte[] bytes = new byte[1024];
 int a ;
 while( ( a = byteOutputStream.read( bytes ) ) != -1){
 byteArrayOutputStream.write( bytes , 0 , a);
 }
 String s = byteArrayOutputStream.toString("utf-8");
 return s;
}catch(IOException e){
 e.printStackTrace();
 return e.getMessage();
}finally{
 if(inputStream != null ){
 try {
 inputStream.close();
 } catch (IOException e) {
 e.printStackTrace();
 }
 }
}


2 . 字符流

BufferedReader reader = null ;
try {
 reader = request.getReader();
 StringBuffer sb = new StringBuffer();
 String str ;
 while (null != (str = reader.readLine())){
 sb.append( str );
 }
 return sb.toString();
} catch (IOException e) {
 e.printStackTrace();
 return e.getMessage();
}finally {
 if(null == reader){
 try {
 reader.close();
 } catch (IOException e) {
 e.printStackTrace();
 }
 }
}

3 . RequestBody方式 直接Map 或者 对象来接收 ,这个需要知道对方传输过来的样式

 

 

    这样Map就可以直接拿到了 .
