我正在建立一个食品订购机器人。我已经在火堆中保存了我的食品类别（即起子，餐，鱼，肉，意大利面等），每种食品类别都可以有多种食品。
这是我在firebase中的食物项目结构

我想要实现的是将我的食物项目（在食物类别下）从firebase同步到api.ai实体。
我在api.ai手动完成，如下所示 http://prntscr.com/fhpme6
现在想通过代码（nodejs）完成所有这些工作 我知道api.ai提供了与实体一起玩的api https://docs.api.ai/docs/entities（我用过它们） 我可以从firebase中提取食物项目并将数据同步到api.ai实体。但有一个问题。我无法覆盖和/或删除我的意图中已经使用过的实体。
以下是我为FoodSync.js
var util = require('util');
var exec = require('child_process').exec;
var apiai_developer_access_code = "e764e24fa51e4d93bdc1e6bde92d07d8"
class FoodSync {
syncFood(firebaseRef, apiAiRef, callback){
//Retrieves a list of all entities for the agent.
var all_entities = 'curl -k -H "Authorization: Bearer '+apiai_developer_access_code+'" "https://api.api.ai/v1/entities?v=20150910"'
var food_category_id = "";
var all_entities_array = [];
var all_food_cat_names = [];
var all_food_cat_entities_id = [];
var that = this;
that.execCommand(all_entities, function(error, stdout, stderr){
var jsonResponse = JSON.parse(stdout)
all_entities_array = jsonResponse;
for(var i = 0; i < jsonResponse.length; i++) {
var entity = jsonResponse[i];
if(entity.name == "food-categories"){
food_category_id = entity.id;
break;
}
}
console.log('food_category_id: ' + food_category_id);
if(food_category_id == ""){
return;
}
var food_category_entity_url = that.getEntityUrlWithID(food_category_id);
console.log('food_category_entity_url: ' + food_category_entity_url);
that.execCommand(food_category_entity_url, function(error, stdout, stderr){
var jsonResponse = JSON.parse(stdout)
console.log('food_category_entity: ' + JSON.stringify(jsonResponse));
var food_cat_all_entities = jsonResponse.entries;
console.log("food_cat_all_entities : "+ food_cat_all_entities.length);
for(var i = 0; i < food_cat_all_entities.length; i++) {
var food_cat_entity = food_cat_all_entities[i];
var food_cat_entity_name = food_cat_entity.value.replace('@', '')
console.log("food_cat_entity_name : "+ food_cat_entity_name);
console.log("all_entities_array.length : "+ all_entities_array.length);
for(var j = 0; j < all_entities_array.length; j++){
var entity_check = all_entities_array[j];
if(entity_check.name == food_cat_entity_name){
all_food_cat_entities_id.push(entity_check.id);
}
}
// Here I got all food-entities id.
console.log('all_food_cat_entities_ids: ' + all_food_cat_entities_id);
// Here I am calling the DELETE entity first (then Recreate), Problem is my entity is used in My some of Intents, So upon delete I am getting the error,

}
})
// if(error !== null){
// console.log('exec error: ' + error);
// callback()
// }
})
}
getEntityUrlWithID(entitiy_id){
// Retrieves the specified entity.
var entities = 'curl -k -H "Authorization: Bearer '+apiai_developer_access_code+'" "https://api.api.ai/v1/entities/'+entitiy_id+'?v=20150910"'
return entities;
}
execCommand(command, callback){
console.log('execCommand: called');
exec(command, function(error, stdout, stderr){
//console.log('stdout: ' + stdout);

if(error !== null){
console.log('exec error: ' + error);

callback(error, stdout, stderr)
});
