Method Detail

getResponseBody

public static byte[] getResponseBody(org.apache.http.HttpResponse resp)
                              throws IOException

Returns the response body of the HTTPResponse, if any, as an array of bytes. If response body is not available or cannot be read, returns null Note: This will cause the entire response body to be buffered in memory. A malicious server may easily exhaust all the VM memory. It is strongly recommended, to use getResponseAsStream if the content length of the response is unknown or reasonably large.

Parameters:

resp - HttpResponse

Returns:

The response body

Throws:

IOException - If an I/O (transport) problem occurs while obtaining the response body.

getResponseBodyAsString

public static String getResponseBodyAsString(org.apache.http.HttpResponse resp)
                                      throws IOException

Returns the response body of the HTTPResponse, if any, as a String. If response body is not available or cannot be read, returns null The string conversion on the data is done using UTF-8. Note: This will cause the entire response body to be buffered in memory. A malicious server may easily exhaust all the VM memory. It is strongly recommended, to use getResponseAsStream if the content length of the response is unknown or reasonably large.

Parameters:

resp - HttpResponse

The response body.

Throws:
