https://quantum6.blog.csdn.net/article/details/118605802

• 范例文本

{
	"command":	"function",
	"name":	"openDocument",
	"params":	{
		"count":	2,
		"param0":	"taishan.docx",
		"param1":	false
	}
}

• 解析取值

cJSON* root = cJSON_Parse(pData);
cJSON *item = cJSON_GetObjectItem(root, "name");
char*  name = cJSON_GetStringValue(item);

item = cJSON_GetObjectItem(root, "params");

cJSON* pItem = cJSON_GetObjectItem(pJson, "count");
printf("%d, %s, %f",
    pItem->valueint,
    pItem->valuestring,
    pItem->valuedouble);

printf("%s, %f",
    cJSON_GetNumberValue(pItem),
    cJSON_GetStringValue(pItem),
    );
