Question

我向支付宝发送请求并得到此回复。我觉得有些字符是汉字，我看不到它们。

如何更改它以便将其视为中文字符或可查看的内容？

这是我在Qt中的代码：

Answer 1

earth_data <- planets_df[planets_df[,"name"]=="Earth",c("diameter", "rotation")]返回response->readAll()，其中以您问题中显示的格式打印（带有不可打印字符的字节使用QByteArray进行编码）。在以这种原始形式打印文本之前，您必须确定它是如何编码的。从我看到的（在这个答案的评论中）你的文本是UTF-8编码。如此简单的转换为\xXY应该可以实现可读的html：

QString

现在，在文档中，您可以找到其他方式，例如QString html(response->readAll());。

要删除html标记并仅获取您必须使用的文本内容QString::fromUtf8。

QTextDocument

从您的评论中我可以看到您不需要这最后一步。

如何让角色可见？
