Constructor & Destructor Documentation

QgsNetworkReplyContent() [1/2]

QgsNetworkReplyContent::QgsNetworkReplyContent ( )

default

Default constructor for an empty reply.

QgsNetworkReplyContent() [2/2]

Member Function Documentation

attribute()

QVariant QgsNetworkReplyContent::attribute

(

QNetworkRequest::Attribute

code

)

const

Returns the attribute associated with the code.

If the attribute has not been set, it returns an invalid QVariant.

You can expect the default values listed in QNetworkRequest::Attribute to be applied to the values returned by this function.

attributes()

Definition at line 45 of file qgsnetworkreply.cpp.

attributes()

QMap< QNetworkRequest::Attribute, QVariant > QgsNetworkReplyContent::attributes ( ) const

inline

Returns a list of valid attributes received in the reply.

attribute()

Note

Not available in Python bindings

Definition at line 66 of file qgsnetworkreply.h.

clear()

void QgsNetworkReplyContent::clear

(

)

Clears the reply, resetting it back to a default, empty reply.

Definition at line 40 of file qgsnetworkreply.cpp.

content()

QByteArray QgsNetworkReplyContent::content ( ) const

inline

Returns the reply content.

This is not available by default, as reading network reply content can only be done once.

Blocking network requests (see QgsBlockingNetworkRequest) will automatically populate this content.

setContent()

Definition at line 158 of file qgsnetworkreply.h.

error()

QNetworkReply::NetworkError QgsNetworkReplyContent::error ( ) const

inline

Returns the reply's error message, or QNetworkReply::NoError if no error was encountered.

See also

errorString()

Definition at line 75 of file qgsnetworkreply.h.

errorString()

QString QgsNetworkReplyContent::errorString ( ) const

inline

Returns the error text for the reply, or an empty string if no error was encountered.

extractFileNameFromContentDispositionHeader()

QString QgsNetworkReplyContent::extractFileNameFromContentDispositionHeader ( const QString &  header )

static

Extracts the filename component of the content disposition header from the header.

Since

QGIS 3.28
