創建 QJsonDocument from data .
validation decides whether the data is checked for validity before being used. By default the data is validated. If the data is not valid, the method returns a null document.
注意： Deprecated in Qt 5.15. The binary JSON encoding is only retained for backwards compatibility. It is undocumented and restrictive in the maximum size of JSON documents that can be encoded. Qt JSON types can be converted to Qt CBOR types, which can in turn be serialized into the CBOR binary format and vice versa. The CBOR format is a well-defined and less restrictive binary representation for a superset of JSON.

創建 QJsonDocument that uses the first size 字節來自 data . It assumes data contains a binary encoded JSON document. The created document does not take ownership of data . The data is copied into a different data structure, and the original data can be deleted or modified afterwards.
data 必須對齊 4 字節邊界。

注意： Before Qt 5.15, the caller had to guarantee that data would not be deleted or modified as long as any QJsonDocument , QJsonObject or QJsonArray still referenced the data. From Qt 5.15 on, this is not necessary anymore.

Returns the raw binary representation of the data size 將包含返迴數據的大小。
This method is useful to e.g. stream the JSON document in its binary form to a file.

The binary representation is also the native format used internally in Qt, and is very efficient and fast to convert to and from.
The binary format can be stored on disk and interchanged with other applications or computers. fromBinaryData () can be used to convert it back into a JSON document.
