如何在C ++中的一个对象中存储多个json对象 [英] How to store multiple json object in one object in C++

问题描述

如何在c ++中的一个对象中存储多个json对象

例如

json :: value obj1;

obj1 [ID ] =12

obj1 [姓名] =abc



json :: value obj2;

obj2 [ID] =11

obj2 [姓名] =xyz



我想要将上述两个对象存储在一个json对象中

json :: value obj3;



outupt如下格式

obj3 = [{ID：12，名称：abc}，{ID：11，名称：xyz}]



我的尝试：



json :: value obj1;

obj1 [ID] =12

obj1 [姓名] =abc



json :: value obj2 ;

obj2 [ID] =11

obj2 [姓名] =xyz





items [0] = item;



group [LItems] = items;



utility :: stringstream_t stream;

group.serialize（stream）;





json :: value obj3;

obj3 [0] = item;



group [LItems] = items;



实用程序： ：stringstream_t stream;

group.serialize（stream）;

解决方案

你有不同的对象如obj1，obj2和obj3。这些对象最好存储在容器对象中，如数组或向量。

 myarray.add（obj1）; 
 myarray.add（obj2）; 
 myarray.add（obj3）; 

为了存储它们，您首先要记下计数而不是每个成员。

how to store multiple json object in one object in c++
For example
json::value obj1;
obj1["ID"]="12"
obj1["Name"]="abc"

json::value obj2;
obj2["ID"]="11"
obj2["Name"]="xyz"

I want to store the above two objects in one json object
json::value obj3;

outupt is like in below format
obj3=[{"ID":"12","Name":"abc"},{"ID":"11","Name":"xyz"}]

What I have tried:

json::value obj1;
obj1["ID"]="12"
obj1["Name"]="abc"

json::value obj2;
obj2["ID"]="11"
obj2["Name"]="xyz"


items[0] = item;

group[L"Items"] = items;

utility::stringstream_t stream;
group.serialize(stream);


json::value obj3;
obj3[0] = item;

group[L"Items"] = items;

utility::stringstream_t stream;
group.serialize(stream);

解决方案

you have different objects as obj1, obj2 and obj3. Such objects are best stored in a container object like array or vector.

myarray.add(obj1);
myarray.add(obj2);
myarray.add(obj3);

For storing them you at first write the count and than every member.
