QT json数据获取错误：C2026：字符串太大，尾随字符被截断

Question

我在QT中遇到关于JSON数据的错误，我在Github上的代码如果json数据少一点，代码可以编译，但是当json数据大一点时，代码无法编译。

比如当json如下时，代码可以编译：

    const std::string json = R"([

这是我的测试数据，我觉得数据不是很大，因为这只是我写应用的一段测试数据。

我谷歌搜索，但没有找到解决方法。我需要比较目录和文件的修改日期以查找更改的目录和文件，目录和文件不固定，因为用户可能想检查某些目录的文件已更改。请参阅我需要做什么。

我阅读了@BoP提供的链接编译器错误C2026。见下图：

我认为我的问题不仅与字符串有关，还与

JSON

格式有关。我应该以什么格式将目录路径写入文件以及如何以 json 格式使用它。

我该如何解决这个问题？谢谢你。

首次更新

当我使用@drescherjm提供的链接code时，我收到错误，请参见下图（但我认为错误是每一行都没有以逗号结尾）：

第二次更新

当我使用@Jarod42 答案时，出现错误，请参见下图：

第三次更新

我提供了链接每行以逗号结尾，见下图：

Answer 1

错误是因为 msvc 编译器对文字 C 字符串的限制。他们提出了一种替代解决方案（资源文件（使用 Qt 很容易））和一种解决方法（连接相邻的分割字符串）。

对于解决方法，类似于：

当你使用Qt时，我强烈建议你使用资源文件（.qrc）。
