Detailed Description

The ViewJson is a view handler that returns Context::stash() data in JSON format. You can limit the exposed stash data by setting the setExposeStash() method to a single key, a list of keys or a regular expression matching specific keys. By default, the complete stash content will be put into the created JSON object. This view also automatically sets the Content-Type HTTP response header to "application/json".

Member Enumeration Documentation

◆ ExposeMode

enum Cutelyst::ViewJson::ExposeMode

This value defines which kind of exposition was defined

Enumerator
All	The complete stash will be put into the JSON object. (the default)
String	Only the content of a single stash key will be put into the JSON object.
StringList	Only the content of the stash keys in the list of keys will be put into the JSON object.
RegularExpression	Only the content of the stash keys that match the regular expression will be put into the JSON object.

Definition at line 57 of file viewjson.h.

◆ JsonFormat

enum Cutelyst::ViewJson::JsonFormat

This value defines the format of the JSON byte array produced when rendering the view.

Enumerator
Indented	The output will be indented
Compact	The output will be compact saving space (the default)

Definition at line 39 of file viewjson.h.

Constructor & Destructor Documentation

◆ ViewJson()

ViewJson::ViewJson	(	QObject *	parent,
		const QString &	name = `QString()`
	)

explicit

Constructs a new ViewJson with the given parent and name.

The name can be used to specify different views that can be called either dynamically by Context::setCustomView() or with the :View() argument of the RenderView action.

Definition at line 15 of file viewjson.cpp.

Member Function Documentation

◆ exposeStashMode()

ViewJson::ExposeMode ViewJson::exposeStashMode ( ) const

Returns the expose mode of the stash keys, defaults to everything (ViewJson::All).

Definition at line 45 of file viewjson.cpp.

◆ outputFormat()

ViewJson::JsonFormat ViewJson::outputFormat ( ) const

Returns the output format of JSON, defaults to ViewJson::Compact.

Definition at line 20 of file viewjson.cpp.

References Compact, QJsonDocument::Compact, Indented, and QJsonDocument::Indented.

◆ render()

QByteArray ViewJson::render ( Context * c ) const

finalvirtual

All subclasses must reimplement this when doing it's rendering. If an error (c->error()) is not set c->response()->body() is defined with the returned value, this is useful if the view is not meant to be used as a body.

Implements Cutelyst::View.

◆ setExposeStash() [1/3]

void ViewJson::setExposeStash ( const QRegularExpression & re )

Specify which stash keys are exposed as a JSON response, this will change exposeStashMode() to ViewJson::RegularExpression. Only keys that match the regular expression re will be exposed to the JSON response.

Definition at line 65 of file viewjson.cpp.

References RegularExpression.

◆ setExposeStash() [2/3]

void ViewJson::setExposeStash ( const QString & key )

Specify which stash key is exposed as a JSON response, this will change exposeStashMode() to ViewJson::String. Only the content of this single key will be exposed to the JSON response.

Definition at line 51 of file viewjson.cpp.

References String.

◆ setExposeStash() [3/3]

void ViewJson::setExposeStash ( const QStringList & keys )

Specify which stash keys are exposed as a JSON response, this will change exposeStashMode() to ViewJson::StringList. Only content of stash keys that are found in the list of keys will be exposed to the JSON response.

Definition at line 58 of file viewjson.cpp.

References StringList.

◆ setOutputFormat()

void ViewJson::setOutputFormat ( JsonFormat format )

Defines the output format of JSON.

Definition at line 33 of file viewjson.cpp.

References Compact, QJsonDocument::Compact, Indented, and QJsonDocument::Indented.

◆ setXJsonHeader()

void ViewJson::setXJsonHeader ( bool enable )

By default this plugin does NOT set X-JSON header if the requested client is a Prototype.js with X-JSON support. By setting enable to true, you can opt-out this behavior so that you do not need to do eval() by your own.

Definition at line 72 of file viewjson.cpp.

◆ xJsonHeader()

bool ViewJson::xJsonHeader ( ) const

Returns true if the X-JSON header should be sent.

Definition at line 78 of file viewjson.cpp.
