        七、擴展知識閱讀:
        


        c語言解析json數據：http://stevengw.blog.163.com/blog/static/5834475120124643458695/
        


        c語言解析json數據
        
我使用的是cJSON:http://sourceforge.net/projects/cjson/
        


        先看json的數據結構 
        
c中沒有對象，所以json數據是采用鏈表存儲的 
        
C代碼  
        


        typedef struct cJSON {   
        
    struct cJSON *next,*prev;   // 數組 對象數據中用到   
        
    struct cJSON *child;        // 數組 和對象中指向子數組對象或值     
        
    int type;           // 元素的類型，如是對象還是數組     
        
    char *valuestring;          // 如果是字符串   
        
    int valueint;               // 如果是數值   
        
    double valuedouble;         // 如果類型是cJSON_Number     
        
    char *string;               // The item's name string, if this item is the child of, or is in the list of subitems of an object.   
        
} cJSON; 
        


        比如你有一個json數據 
        


        Javascript代碼  
        
{   
        
    "name": "Jack (\"Bee\") Nimble",    
        
    "format": {   
        
        "type":       "rect",    
        
        "width":      1920,    
        
        "height":     1080,    
        
        "interlace":  false,    
        
        "frame rate": 24   
        
    }   
        
} 
        


        那么你可以 
        
1：講字符串解析成json結構體。 
        
C代碼  
        
cJSON *root = cJSON_Parse(my_json_string); 
        
2:獲取某個元素 
        
C代碼  
        
cJSON *format = cJSON_GetObjectItem(root,"format");   
        
int framerate = cJSON_GetObjectItem(format,"frame rate")->valueint; 
        
3:講json結構體轉換成字符串 
        
C代碼  
        
char *rendered=cJSON_Print(root); 
        
4：刪除 
        
C代碼  
        
cJSON_Delete(root); 
        
5：構建一個json結構體 
        
C代碼  
        
 
        


        

        cJSON *root,*fmt;   
        
root=cJSON_CreateObject();     
        
cJSON_AddItemToObject(root, "name", cJSON_CreateString("Jack (\"Bee\") Nimble"));   
        
cJSON_AddItemToObject(root, "format", fmt=cJSON_CreateObject());   
        
cJSON_AddStringToObject(fmt,"type",     "rect");   
        
cJSON_AddNumberToObject(fmt,"width",        1920);   
        
cJSON_AddNumberToObject(fmt,"height",       1080);   
        
cJSON_AddFalseToObject (fmt,"interlace");   
        
cJSON_AddNumberToObject(fmt,"frame rate",   24);
