回复: 大佬来，QString比较尴尬的地方！

试试这个...
QString request = ui->request->toPlainText().trimmed();
const auto& bytes = request .toUtf8();
const char *data = bytes.data();

Before version 7.17.0, strings were not copied. Instead the user was forced keep them available until libcurl no longer needed them.
坑在curl这边，你看一下curl的版本

我的是7.37.0，我现在试试你那个方法。
curl应该没问题，因为同样.data()不稳定的问题，我在一个aes加密函数里也出现了。
