Detailed Description

Download content from the content repository.

Note
Clients SHOULD NOT generate or use URLs which supply the access token in the query string. These URLs may be copied by users verbatim and provided in a chat message to another user, disclosing the sender's access token.

Clients MAY be redirected using the 307/308 responses below to download the request object. This is typical when the homeserver uses a Content Delivery Network (CDN).

Constructor & Destructor Documentation

◆ GetContentAuthedJob()

Quotient::GetContentAuthedJob::GetContentAuthedJob ( const QString &  serverName,
const QString &  mediaId,
qint64  timeoutMs = 20000 
)
explicit
Parameters
serverNameThe server name from the mxc:// URI (the authority component).
mediaIdThe media ID from the mxc:// URI (the path component).
timeoutMsThe maximum number of milliseconds that the client is willing to wait to start receiving data, in the case that the content has not yet been uploaded. The default value is 20000 (20 seconds). The content repository SHOULD impose a maximum value for this parameter. The content repository MAY respond before the timeout.

Member Function Documentation

◆ contentDisposition()

QString Quotient::GetContentAuthedJob::contentDisposition ( ) const
inline

The disposition of the returned content. MUST be one of inline or attachment, and SHOULD contain a file name.

If the Content-Type is allowed in the restrictions for serving inline content, servers SHOULD use inline, otherwise they SHOULD use attachment.

If the upload was made with a filename, this header MUST contain the same filename. Otherwise, filename is excluded from the header. If the media being downloaded is remote, the remote server's filename in the Content-Disposition header is used as the filename instead. When the header is not supplied, or does not supply a filename, the local download response does not include a filename.

Definition at line 84 of file authed-content-repo.h.

◆ contentType()

QString Quotient::GetContentAuthedJob::contentType ( ) const
inline

The content type of the file that was previously uploaded.

The server MUST return a Content-Type which is either exactly the same as the original upload, or reasonably close. The bounds of "reasonable" are:

  • Adding a charset to text/* content types.
  • Detecting HTML and using text/html instead of text/plain.
  • Using application/octet-stream when the server determines the content type is obviously wrong. For example, an encrypted file being claimed as image/png.
  • Returning application/octet-stream when the media has an unknown/unprovided Content-Type. For example, being uploaded before the server tracked content types or when the remote server is non-compliantly omitting the header entirely.

Actions not in the spirit of the above are not considered "reasonable".

Definition at line 65 of file authed-content-repo.h.

◆ data()

QIODevice* Quotient::GetContentAuthedJob::data ( )
inline

The content that was previously uploaded.

Definition at line 90 of file authed-content-repo.h.

◆ makeRequestUrl()

static QUrl Quotient::GetContentAuthedJob::makeRequestUrl ( const HomeserverData hsData,
const QString &  serverName,
const QString &  mediaId,
qint64  timeoutMs = 20000 
)
static

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

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