exe: Microsoft C++ exception: nlohmann::detail::parse_error at memory location 0x0021F450. 诚然,我不擅长调试,并且自学过C++,所以在我的知识中肯定有很多空白,但是我已经尝试了将数据放入数组的不同方法,比如将数组定义为json arrPages[99],以防它是数组的问题,但这个问题仍然存在。 我真的希望有人能分享一...
当你稍后使用json::parse(ifs)时，你试图解析本质上是一个空文件，而空字符串不是一个有效的json文档。

由于字符串的格式不正确,json::parse函数会抛出一个json::parse_error异常。我们使用try-catch语句来捕获这个异常,并输出一个错误消息。此外,我们还捕获了其他可能的异常类型,如json::type_error和其他标准异常,以确保程序的健壮性。 以上就是关于nlohmann json库中的json::parse函数的详细解释和使用示例。希望这些...
Memory efficiency. Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types:std::stringfor strings,int64_t,uint64_tordoublefor numbers,std::mapfor objects,std::vectorfor...
accept,basic_json::sax_parse,basic_json::from_cbor,basic_json::from_msgpack,basic_json::from_ubjson,basic_json::from_bson) via initializer lists is deprecated. Instead, pass two iterators; for instance, callbasic_json::from_cbor(ptr, ptr+len)instead ofbasic_json::from_cbor({ptr, len})...

It does not return a json value - it is up to you to decide what to do with the SAX events. Furthermore, no exceptions are thrown in case of a parse error - it is up to you what to do with the exception object passed to your parse_error implementation. Internally, the SAX ...
