简单好用的C++ json库——JSON for Modern C++ github传送门为:https://nlohmann.github.io/json/ 简介 首先这个库不是奔着性能去的,设计者考虑的是:直观的语法(Intuitive syntax)、微小的整合(Trivial integration)、认真的测试(Serious testing) 至于内存效率和速度,反倒不是优先考虑的。 先说说微小的整合。在项...
Thecppvsdbgdebugger configuration also contains anenvFileproperty that allows you to easily set variables for debugging purposes. For example: project.env file: # project.env# Example environment with key as 'MYENVRIONMENTPATH' and value as C:\\Users\\USERNAME\\ProjectMYENVRIONMENTPATH=C:\\Us...
// 使用push_back创建Arrayjson j;j.push_back("foo");j.push_back(1);j.push_back(true);// 也可以使用C++11标准中的emplace_backj.emplace_back(1.78);// 通过iterator遍历这个Arrayfor(json::iterator it=j.begin();it!=j.end();++it){std::cout<<*it<<'\n';}// 或者C++11中的范围forf...
Order of keys in the format string does not matter, and the format string may omit keys to fetch only those that are of interest, for example, assume str is a JSON string { "a": 123, "b": "hi", c: true }. We can fetch only the value of the c key: int value = 0; jso...
cJSON*cJSON_GetObjectItem(cJSON*object,constchar*string);//根据键获取对应的值(cjson对象)/* For analysing failed parses. This returns a pointer to the parse error. You'll probably need to look a few chars back to make sense of it. Defined when cJSON_Parse() returns 0. 0 when cJSON...
