Detailed Description

Get information about a URL for a client.

Note: Replaced by GET /_matrix/client/v1/media/preview_url.

Get information about a URL for the client. Typically this is called when a client sees a URL in a message and wants to render a preview for the user.

Note: Clients should consider avoiding this endpoint for URLs posted in encrypted rooms. Encrypted rooms often contain more sensitive information the users do not want to share with the homeserver, and this can mean that the URLs being shared should also not be shared with the homeserver.

Constructor & Destructor Documentation

◆ GetUrlPreviewJob()

Quotient::GetUrlPreviewJob::GetUrlPreviewJob	(	const QUrl &	url,
		std::optional< qint64 >	ts = `std::nullopt`
	)

explicit

Parameters

url	The URL to get a preview of.
ts	The preferred point in time to return a preview for. The server may return a newer version if it does not have the requested version available.

Member Function Documentation

◆ makeRequestUrl()

static QUrl Quotient::GetUrlPreviewJob::makeRequestUrl	(	const HomeserverData &	hsData,
		const QUrl &	url,
		std::optional< qint64 >	ts = `std::nullopt`
	)

static

Construct a URL without creating a full-fledged job object.

This function can be used when a URL for GetUrlPreviewJob is necessary but the job itself isn't.

◆ matrixImageSize()

std::optional<qint64> Quotient::GetUrlPreviewJob::matrixImageSize ( ) const

inline

The byte-size of the image. Omitted if there is no image attached.

Definition at line 462 of file content-repo.h.

◆ ogImage()

QUrl Quotient::GetUrlPreviewJob::ogImage ( ) const

inline

An mxc:// URI to the image. Omitted if there is no image.
