C++ QT5.7-为什么我用QString得到格式错误的json值，而用std:：string得到格式完美的json值？

我尝试从RubyonRails中的api获取json响应

当我直接用curl或postman调用这个url时，我得到了一个完美的json响应

当我使用静态编译的QT5.7 windows的32位程序时，只有在使用std:：string时，我才能得到完美的响应

但是，如果我使用QDebug打印QString（）我会得到一个格式错误且奇怪的结果：

“，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，，\”“C/C/per/per/C/per/lib/pods/pods/pod/pod/pepe勒姆床.pod.pod”中，“C/C/C/per/per/per/perper/per/lib/lib/pods/pod/pods/pods/pods/perLeLepepepepepepepepepes/pod/pod/pod/pod/pod/perleleleleleleleleleleleperperperperperperperperperperperperperperperperperperperperperperperperperperperperperperperperperper实验室实验室实验室。pod.pod.pod.pod.pod.pod”中，”pod\““，，，，“C/C/C/C/C/C/C/C/C/C/C/C/per/per/per/per/per/per/per/per/per/per/per/per/per/per/perAQ6.pod\“，\”“C/C/C/per/Perl/lib/pods/pods/pods/perlfaq8.pod8.pod8.pod8.pod”中，“C/C/C/per/per/per/per/per/Perl/lib/lib/pod/pods/pods/pod/pod/pod/pod/pod/pod8/pod8.pod8.pod8.pod8.pod”中，“C/C/C/C/C/C/C/C/C/C/per/per/per/per/per/Perl/Perl/Perl/Perl/Perl/Perl/Perl/Perl/Perl/Perl/Perl/Perl/Perl/lib/pod/pos/pod/pod/pod/pod/pod/pod/pod/pod/pod/pod/pod/pod/pod/pod/po萨乌夫

因此，如果我打印std:：string，我就有了一个完美的json，这正是我想要的：

我不知道我能做什么，因为我需要用QString为QJsonDocument和QJsonObject解析json

我尝试过很多事情，比如

或者（对于理解和调试来说很难看），比如：

谢谢

您是否使用

qDebug（）

进行标准输出？这不是它应该使用的功能

---

它以调试格式显示许多类型的当前内容。对于

QString

，它意味着引号中的字符串带有特定字符-包括双引号-用\转义。这并不意味着字符串本身包含转义数据。它仅由

QDebug

以这种方式呈现给您，您不能转换std字符串吗后来到一个qstring？感谢这个错误，我们讨论了QT5.7是的，我已经尝试过了，但仍然是相同的结果，我尝试过用QBytesArray转换，仍然是相同的Too。是不是因为它是随机的，正如你所看到的，在好的json格式中没有特殊的字符，所以无法进行比较？问题不是j
