javax.servlet Class ServletInputStream
java.lang.Objectjava.io.InputStream
- 所有已实现的接口:
- Closeable
public abstract class ServletInputStream
- extends InputStream
Provides an input stream for reading binary data from a client
request, including an efficient readLine method
for reading data one line at a time. With some protocols, such
as HTTP POST and PUT, a ServletInputStream
object can be used to read data sent from the client.
A ServletInputStream object is normally retrieved via
the ServletRequest.getInputStream() method.
This is an abstract class that a servlet container implements.
Subclasses of this class
must implement the java.io.InputStream.read() method.

readLine
public int readLine(byte[] b,
int off,
int len)
throws IOException
- Reads the input stream, one line at a time. Starting at an
offset, reads bytes into an array, until it reads a certain number
of bytes or reaches a newline character, which it reads into the
array as well.
This method returns -1 if it reaches the end of the input stream before reading the maximum number of bytes.
- 参数:
b- an array of bytes into which data is readoff- an integer specifying the character at which this method begins readinglen- an integer specifying the maximum number of bytes to read- 返回:
- an integer specifying the actual number of bytes read, or -1 if the end of the stream is reached
- 抛出异常:
IOException- if an input or output exception has occurred
