Class HttpResponse (1.43.1)

public final class HttpResponse

HTTP response.

Callers should call #disconnect when the HTTP response object is no longer needed. However, #disconnect does not have to be called if the response stream is properly closed. Example usage:

HttpResponse response = request.execute(); try { // process the HTTP response object } finally { response.disconnect(); }

Implementation is not thread-safe.

Methods

<T>parseAs(Class<T> dataClass)

public T <T>parseAs(Class<T> dataClass)

Parses the content of the HTTP response from #getContent() and reads it into a data class of key/value pairs using the parser returned by HttpRequest#getParser().

Reference: http://tools.ietf.org/html/rfc2616#section-4.3

Parameter
NameDescription
dataClassClass<T>
Returns
TypeDescription
T

parsed data class or null for no content

Exceptions
TypeDescription
IOException

disconnect()

public void disconnect()

Disconnect using LowLevelHttpResponse#disconnect(), then close the HTTP response content using #ignore.

Exceptions
TypeDescription
IOException

download(OutputStream outputStream)

public void download(OutputStream outputStream)

Writes the content of the HTTP response into the given destination output stream.

Sample usage:

HttpRequest request = requestFactory.buildGetRequest( new GenericUrl("https://www.google.com/images/srpr/logo3w.png")); OutputStream outputStream = new FileOutputStream(new File("/tmp/logo3w.png")); try { HttpResponse response = request.execute(); response.download(outputStream); } finally { outputStream.close(); }

This method closes the content of the HTTP response from #getContent().

This method does not close the given output stream.

Parameter
NameDescription
outputStreamOutputStream

destination output stream

Exceptions
TypeDescription
IOException

I/O exception

getContent()

public InputStream getContent()

Returns the content of the HTTP response.

The result is cached, so subsequent calls will be fast.

Callers should call InputStream#close after the returned InputStream is no longer needed. Example usage:

InputStream is = response.getContent(); try { // Process the input stream.. } finally { is.close(); }

HttpResponse#disconnect does not have to be called if the content is closed.

Returns
TypeDescription
InputStream

input stream content of the HTTP response or null for none

Exceptions
TypeDescription
IOException

I/O exception

getContentCharset()

public Charset getContentCharset()

Returns the Charset specified in the Content-Type of this response or the ISO-8859-1 charset as a default.

Returns
TypeDescription
Charset

getContentEncoding()

public String getContentEncoding()

Returns the content encoding or null for none.

Returns
TypeDescription
String

getContentLoggingLimit()

public int getContentLoggingLimit()

Returns the limit to the content size that will be logged during #getContent().

Content will only be logged if #isLoggingEnabled is true.

If the content size is greater than this limit then it will not be logged.

Can be set to 0 to disable content logging. This is useful for example if content has sensitive data such as authentication information.

Defaults to HttpRequest#getContentLoggingLimit().

Returns
TypeDescription
int

getContentType()

public String getContentType()

Returns the content type or null for none.

Returns
TypeDescription
String

getHeaders()

public HttpHeaders getHeaders()

Returns the HTTP response headers.

Returns
TypeDescription
HttpHeaders

getMediaType()

public HttpMediaType getMediaType()

Returns the parsed Content-Type in form of a HttpMediaType or null if no content-type was set.

Returns
TypeDescription
HttpMediaType

getRequest()

public HttpRequest getRequest()

Returns the HTTP request.

Returns
TypeDescription
HttpRequest

getStatusCode()

public int getStatusCode()

Returns the HTTP status code or 0 for none.

Returns
TypeDescription
int

getStatusMessage()

public String getStatusMessage()

Returns the HTTP status message or null for none.

Returns
TypeDescription
String

getTransport()

public HttpTransport getTransport()

Returns the HTTP transport.

Returns
TypeDescription
HttpTransport

ignore()

public void ignore()

Closes the content of the HTTP response from #getContent(), ignoring any content.

Exceptions
TypeDescription
IOException

isLoggingEnabled()

public boolean isLoggingEnabled()

Returns whether logging should be enabled on this response.

Defaults to HttpRequest#isLoggingEnabled().

Returns
TypeDescription
boolean

isSuccessStatusCode()

public boolean isSuccessStatusCode()

Returns whether received a successful HTTP status code >= 200 && < 300 (see #getStatusCode()).

Returns
TypeDescription
boolean

parseAs(Type dataType)

public Object parseAs(Type dataType)

Parses the content of the HTTP response from #getContent() and reads it into a data type of key/value pairs using the parser returned by HttpRequest#getParser().

Parameter
NameDescription
dataTypeType
Returns
TypeDescription
Object

parsed data type instance or null for no content

Exceptions
TypeDescription
IOException

parseAsString()

public String parseAsString()

Parses the content of the HTTP response from #getContent() and reads it into a string.

Since this method returns "" for no content, a simpler check for no content is to check if #getContent() is null.

All content is read from the input content stream rather than being limited by the Content-Length. For the character set, it follows the specification by parsing the "charset" parameter of the Content-Type header or by default "ISO-8859-1" if the parameter is missing.

Returns
TypeDescription
String

parsed string or "" for no content

Exceptions
TypeDescription
IOException

I/O exception

setContentLoggingLimit(int contentLoggingLimit)

public HttpResponse setContentLoggingLimit(int contentLoggingLimit)

Set the limit to the content size that will be logged during #getContent().

Content will only be logged if #isLoggingEnabled is true.

If the content size is greater than this limit then it will not be logged.

Can be set to 0 to disable content logging. This is useful for example if content has sensitive data such as authentication information.

Defaults to HttpRequest#getContentLoggingLimit().

Parameter
