enum QNetworkRequest::?Attribute
QNetworkRequest和QNetworkReply的屬性代碼.
屬性是額外的元數(shù)據(jù),可以被用來去控制請求的行為,以及傳遞從應(yīng)答反饋的進一步的信息到應(yīng)用程序上.屬性也是可以擴展的,允許自定義實現(xiàn)去傳遞自定義值.
The following table explains what the default attribute codes are, the QVariant types associated, the default value if said attribute is missing and whether it's used in requests or replies.

以下的表格解釋了默認的屬性代碼是什么
