Note that in case of multimaps, only one key is used in the JSON object and the value depends on the internal order of the STL container. std::map<std::string, int> c_map { {"one", 1}, {"two", 2}, {"three", 3} }; json j_map(c_map); // {"one": 1, "three": 3...

我们storage的存储方式如果是对象必须先转字符串,所以用JSON.stringify转化后,才能正常提取。否则结果就会丢失数据呈现[object]!!! 也就是说无法存储对象, 结果得用JSON.parse(JSON.stringify(strongage)) 深度解析字符串,但很多人都叫做深拷贝,但是无论从英文字面翻译或者实际过程都有差距!
When working with more complex data structures, you may encounter nested objects. Fortunately,JSON.stringify()can handle these as well. Let’s look at an example with a nested object. constproduct={id:101,name:"Laptop",specifications:{processor:"Intel i7",ram:"16GB",storage:"512GB SSD"}}...
schema 定义一个嵌套的 object,读取属性时是root.layer1.layer2;但是读取对应 schema 时是root.properties.layer1.properties.layer2。每一层属性多读一层properties。 在设计中,默认是仅具备required的属性,然后选择框中包括properties的其它属性。可以再加属性。dependencies不对属性选择进行特殊设置,只是不可用的属性禁...
