Constructor Detail

Response

Response()

Internal only! Creates a dummy HttpConnection.Response, useful for testing. All actual responses are created from the HttpURLConnection and fields defined.

Response

private Response(java.net.HttpURLConnection conn,
                 HttpConnection.Request request,
                 @Nullable
                 HttpConnection.Response previousResponse)
          throws java.io.IOException

Throws:

java.io.IOException

Method Detail

execute

static HttpConnection.Response execute(HttpConnection.Request req)
                                throws java.io.IOException

Throws:

java.io.IOException

execute

static HttpConnection.Response execute(HttpConnection.Request req,
                                       @Nullable
                                       HttpConnection.Response previousResponse)
                                throws java.io.IOException

Throws:

java.io.IOException

statusCode

public int statusCode()

Description copied from interface: Connection.Response

Get the status code of the response.

Specified by:

statusCode in interface Connection.Response

Returns:

status code

statusMessage

public java.lang.String statusMessage()

Description copied from interface: Connection.Response

Get the status message of the response.

Specified by:

statusMessage in interface Connection.Response

Returns:

status message

charset

public java.lang.String charset()

Description copied from interface: Connection.Response

Get the character set name of the response, derived from the content-type header.

Specified by:

charset in interface Connection.Response

Returns:

character set name if set, null if not

charset

public HttpConnection.Response charset(java.lang.String charset)

Description copied from interface: Connection.Response

Set / override the response character set. When the document body is parsed it will be with this charset.

Specified by:

charset in interface Connection.Response

Parameters:

charset - to decode body as

Returns:

this Response, for chaining

contentType

public java.lang.String contentType()

Description copied from interface: Connection.Response

Get the response content type (e.g. "text/html");

Specified by:

contentType in interface Connection.Response

Returns:

the response content type, or null if one was not set

parse

public Document parse()
               throws java.io.IOException

Description copied from interface: Connection.Response

Read and parse the body of the response as a Document. If you intend to parse the same response multiple times, you should Connection.Response.bufferUp() first.

Specified by:

parse in interface Connection.Response

Returns:

a parsed Document

Throws:

java.io.IOException - on error

prepareByteData

private void prepareByteData()

body

public java.lang.String body()

Description copied from interface: Connection.Response

Get the body of the response as a plain string.

Specified by:

body in interface Connection.Response

Returns:

body

bodyAsBytes

public byte[] bodyAsBytes()

Description copied from interface: Connection.Response

Get the body of the response as an array of bytes.

Specified by:

bodyAsBytes in interface Connection.Response

Returns:

body bytes

bufferUp

public Connection.Response bufferUp()

Description copied from interface: Connection.Response

Read the body of the response into a local buffer, so that Connection.Response.parse() may be called repeatedly on the same connection response (otherwise, once the response is read, its InputStream will have been drained and may not be re-read). Calling Connection.Response.body() or Connection.Response.bodyAsBytes() has the same effect.

Specified by:

bufferUp in interface Connection.Response

Returns:

this response, for chaining

bodyStream

public java.io.BufferedInputStream bodyStream()

Description copied from interface: Connection.Response

Get the body of the response as a (buffered) InputStream. You should close the input stream when you're done with it. Other body methods (like bufferUp, body, parse, etc) will not work in conjunction with this method.

This method is useful for writing large responses to disk, without buffering them completely into memory first.

Specified by:

bodyStream in interface Connection.Response

Returns:

the response body input stream

createConnection

private static java.net.HttpURLConnection createConnection(HttpConnection.Request req)
                                                    throws java.io.IOException

Throws:

java.io.IOException

safeClose

private void safeClose()

Call on completion of stream read, to close the body (or error) stream. The connection.disconnect allows keep-alives to work (as the underlying connection is actually held open, despite the name).

createHeaderMap

private static java.util.LinkedHashMap<java.lang.String,java.util.List<java.lang.String>> createHeaderMap(java.net.HttpURLConnection conn)

processResponseHeaders

void processResponseHeaders(java.util.Map<java.lang.String,java.util.List<java.lang.String>> resHeaders)

setOutputContentType

@Nullable
private static java.lang.String setOutputContentType(Connection.Request req)

writePost

private static void writePost(Connection.Request req,
                              java.io.OutputStream outputStream,
                              @Nullable
                              java.lang.String boundary)
                       throws java.io.IOException

Throws:

java.io.IOException

serialiseRequestUrl

private static void serialiseRequestUrl(Connection.Request req)
                                 throws java.io.IOException

Throws:

java.io.IOException
