QDataStream should not be used on content whose provenance cannot be trusted. But note that QDataStream adds control information to the output, so that probably doesn't result in exactly what you want. Serialization of more complex data is accomplished by breaking up the data into primitive units. A data stream is a binary stream of encoded information which is 100% inde- pendent of the host computer's operating system, CPU or byte order. Applications should be designed to attempt to decode only streams whose provenance is at least as trustworthy as that of the application itself or its plugins. 0就开始形成了,很有可能在将来继续进化已反应Qt的变化。 当操作复杂数据类型时,我们就要确保读取和写入时的QDataStream版本是一样的。 如果你需要向前和向后兼容,可以在代码中使用硬编码指定流的版本号: Oct 5, 2017 · Why do you think you need (or want) to seek within the QIODevice whilst using QDataStream? Just let the QDataStream do its thing as per the documentation. Everything seems fine the first time, but when I try to get back to a certain position using seek,. bin"; QFile file (fileP… QDataStream 不适用于来源不可信的内容。 在设计应用程序时,应尽量只对其来源至少与应用程序本身或其插件的来源同样可信的数据流进行解码。 另请参阅 QTextStream 和 QVariant 。 Jul 30, 2023 · 版本 QDataStream的二进制格式从Qt1.
