我在QT中遇到了JSON数据的错误,my code on Github如果json数据少一点,代码可以编译运行,但是json数据大一点,代码就不能编译运行了。你可以克隆我的github代码来测试,我确信它可以用短json编译并运行,当你编译完成后,点击DisplayDirAndFileDifferent按钮,你会看到下面的图片:
x1c 0d1x的数据
当json很短的时候,比如下面,代码可以编译运行:

const std::string json = R"([

这里是My test data,我认为数据不是很大,因为它只是I write application的一段测试数据。
我谷歌搜索,但没有找到一个方法来解决它。我需要比较目录和文件的修改日期,以找到什么目录和文件更改,目录和文件是不固定的,因为用户可能想检查一些目录的文件更改。参见What do for I write application
我读了@BoP提供的链接Compiler Error C2026。见下图:


我想我的问题不仅仅是字符串,还有JSON。我应该以什么格式写入文件的目录路径,以及如何以json格式使用它。

我该怎么解决这个问题呢?谢谢。JSON格式可以非常灵活,只要代码正确。

首次更新

当我使用@drescherjm提供的链接code时,我得到了错误,见下图(但我认为错误是每行都没有逗号结束,but except for the last line,请参阅四个更新,可以工作json格式):


第二次更新

当我使用@Jarod42答案,我得到错误见下图:


第三次更新

I provided link每行以逗号结尾,but except for the last line,见下图:

当json数据很短时,progrma可以编译并运行。JSON是:

错误是由于msvc编译器对文字C字符串的限制。他们提出了一个替代解决方案(资源文件(这在Qt中很容易))和一个变通方案(连接相邻的拆分字符串)。
对于解决方法,它将类似于:
