方法详细资料

getInputStream

InputStream getInputStream()
                    throws IOException

Returns a InputStream suitable for reading binary data in the response. The servlet container does not encode the binary data.

返回:

a InputStream for reading binary data

抛出:

IOException - if an input or output exception occurred

getStatus

int getStatus()

Gets the current status code of this response.

返回:

the current status code of this response

containsHeader

boolean containsHeader(String name)

Returns a boolean indicating whether the named response header has already been set.

参数:

name - the header name

返回:

true if the named response header has already been set; false otherwise

setHeader

void setHeader(String name,
               String value)

Sets a response header with the given name and value. If the header had already been set, the new value overwrites the previous one. The containsHeader method can be used to test for the presence of a header before setting its value.

参数:

name - the name of the header

value - the header value If it contains octet string, it should be encoded according to RFC 2047 (http://www.ietf.org/rfc/rfc2047.txt)

另请参阅:

containsHeader(java.lang.String), addHeader(java.lang.String, java.lang.String)

addHeader

void addHeader(String name,
               String value)

Adds a response header with the given name and value. This method allows response headers to have multiple values.

参数:

name - the name of the header

value - the additional header value If it contains octet string, it should be encoded according to RFC 2047 (http://www.ietf.org/rfc/rfc2047.txt)

另请参阅:

setHeader(java.lang.String, java.lang.String)

getHeader

String getHeader(String name)

Gets the value of the response header with the given name.

If a response header with the given name exists and contains multiple values, the value that was added first will be returned.

This method considers only response headers set or added via setHeader(java.lang.String, java.lang.String), addHeader(java.lang.String, java.lang.String), respectively.

参数:

name - the name of the response header whose value to return

返回:

the value of the response header with the given name, or null if no header with the given name has been set on this response

getHeaders

Collection<String> getHeaders(String name)

Gets the values of the response header with the given name.

This method considers only response headers set or added via setHeader(java.lang.String, java.lang.String), addHeader(java.lang.String, java.lang.String), respectively.

Any changes to the returned Collection must not affect this HttpServletResponse.

参数:

name - the name of the response header whose values to return

返回:

a (possibly empty) Collection of the values of the response header with the given name

getHeaderNames

Collection<String> getHeaderNames()

Gets the names of the headers of this response.

This method considers only response headers set or added via setHeader(java.lang.String, java.lang.String), addHeader(java.lang.String, java.lang.String), respectively.

Any changes to the returned Collection must not affect this HttpServletResponse.

返回:

a (possibly empty) Collection of the names of the headers of this response
