示例1: read
import javax.servlet.ServletInputStream; //导入方法依赖的package包/类
/**
* Reads a line into the specified byte array. The data is read until a newline
* character is encountered (all of "\n", "\r", "\n\r", "\r\n" are considered a
* newline character) or a maximum number of bytes is read. Thus the clients
* should not expect the result to be always a complete line. The amximum number
* of bytes is dictated by the length of the byte array.
*
* This wrapper is introduced in order not to return -1, when a line cannot be
* read, but to throw an IOException instead, since this situation is erroneous
* anyway.
*
* @param input
* A ServletInputStream from which to read data.
* @param buffer
* A byte array where to put the data
* @throws java.io.IOException
* If an I/O error happens.
* @return
* The number of bytes read.
