我正在构建一个从themoviedb.com获取电影信息的应用程序.该信息在JSON文件中提供.我正在尝试使用boost属性树存储信息.但有一点问题.

我通过以下代码说明了这个问题:

#include <vector>
#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/json_parser.hpp>
#include <boost/foreach.hpp>

using namespace std;
using boost::property_tree::ptree;

class single_t{
    int             sID;
    string          sName;
public:
    void            setID(int ID){sID=ID;}
    int             getID(){return sID;}
    void            setName(string Name){sName=Name;}
    string          getName(){return sName;}
};

typedef vector<single_t*> multiple_t;

class foo{
    string          fTitle;
    multiple_t      fItems;
public:
    string          getTitle(){return fTitle;}
    void            setTitle(string Title){fTitle=Title;}
    multiple_t      getItems(){return fItems;}
    void            setItems(multiple_t Items){fItems = Items;}
    void            setItems(single_t Item){fItems.push_back(&Item);}
};

int main () {
    try{
        string response = "{\"title\":\"Foo\",\"items\":[{\"id\":123,\"name\":\"test1\"},{\"id\":456,\"name\":\"test2\"}]}";

        ptree pt;
        stringstream ss; ss << response;
        read_json(ss, …

我想使用 Boost（属性树）库来解析以下有效的 JSON 文件：

{
    "user": {
        "userID": "5C118C8D-AA65-49C0-B907-348DE87D6665",
        "dateProperty": "05-06-2015"
    },
    "challenges": [
        {
            "question#1": "answer",
            "value": 5
        },
        {
            "question": "answer",
            "value": 5
        },
        {
            "question": "answer",
            "value": 5
        },
        {
            "question": "answer",
            "value": 5
        },
        {
            "question": "answer",
            "value": 5
        },
        {
            "question": "answer",
            "value": 5
        },
        {
            "question": "answer",
            "value": 5
        },
        {
            "question": "answer",
            "value": 5
        },
        {
            "question": "answer",
            "value": 5
        },
        {
            "question": "answer",
            "value": 5
        }
    ] }

我确实验证了 JSON 格式是正确的。

我还咨询了几个网站，例如： …
