Sets whether to disable GZip compression of HTTP content.
By default it is false
.

setRequestHeaders(HttpHeaders headers)
public AbstractGoogleClientRequest<T> setRequestHeaders(HttpHeaders headers)
Sets the HTTP headers used for the Google client request.
These headers are set on the request after #buildHttpRequest is called, this means that HttpRequestInitializer#initialize is called first.
Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.

AbstractGoogleClientRequest<T> |
setReturnRawInputStream(boolean returnRawInputStream)
public AbstractGoogleClientRequest<T> setReturnRawInputStream(boolean returnRawInputStream)
Sets whether the response should return raw input stream or not.
By default it is false
.
When the response contains a known content-encoding header, the response stream is wrapped with an InputStream that decodes the content. This fails when we download large files in chunks (see #1009 ). Setting this to true will make the response return the raw input stream.
