Method Detail

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().

Upgrade warning: prior to version 1.9, the default was 100,000 bytes, but now it is HttpRequest.getContentLoggingLimit().

Since:
1.7

setContentLoggingLimit

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().

Upgrade warning: prior to version 1.9, the default was 100,000 bytes, but now it is HttpRequest.getContentLoggingLimit().

Since:

setLoggingEnabled

public HttpResponse setLoggingEnabled(boolean loggingEnabled)
Sets whether logging should be enabled on this response.

Defaults to HttpRequest.isLoggingEnabled().

Since:

getContentType

public String getContentType()
Returns the content type or null for none.

Since:

getHeaders

public HttpHeaders getHeaders()
Returns the HTTP response headers.

Since:

isSuccessStatusCode

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

Since:

getStatusCode

public int getStatusCode()
Returns the HTTP status code or 0 for none.

getTransport

public HttpTransport getTransport()
Returns the HTTP transport.

getContent

public InputStream getContent()
                       throws IOException
Returns the content of the HTTP response.

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

Returns:
input stream content of the HTTP response or null for none
Throws:
IOException - I/O exception

download

public void download(OutputStream outputStream)
              throws IOException
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.

Parameters:
outputStream - destination output stream
Throws:
IOException - I/O exception
Since:
1.9

ignore

public void ignore()
            throws IOException
Closes the content of the HTTP response from getContent(), ignoring any content.

Throws:
IOException

disconnect

public void disconnect()
                throws IOException
Disconnect using LowLevelHttpResponse.disconnect().

Throws:
IOException
Since:

getParser

public HttpParser getParser()
Returns the HTTP response content parser to use for the content type of this HTTP response or null for none.


parseAs

public <T> T parseAs(Class<T> dataClass)
          throws IOException
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 getParser() .

Returns:
parsed data class or null for no content
Throws:
IOException - I/O exception
IllegalArgumentException - if no parser is defined for the given content type or if there is no content type defined in the HTTP response

parseAsString

public String parseAsString()
                     throws IOException
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.

Returns:
parsed string or "" for no content
Throws:
IOException - I/O exception
