这是我一直用来阅读boost::property_tree::json_parser::read_json的json文件的同伦
它始终有效。

我将我的 boost 版本从 1.58.0 升级到 1.65.0，现在我收到了因为评论的异常。当我删除评论时，一切都很好。
是我哪里弄错了还是新版boost的bug？
最佳答案
评论不是 JSON。
旧的解析器确实有它们，但没有正确支持 unicode。
这是 the release notes for Boost 1.59.0 中的消息:
Property Tree:
- A new JSON parser with full Unicode support.
- Breaking change: The new parser does not support comments or string concatenation in JSON files. These features were non-standard extensions of the old parser but their removal could break code which was relying on them.
关于c++ - 是否允许在 JSON 文件中对 boost read_json 进行注释？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46187201/
