本视频是Telegram Bot 机器人编程系列的第四集。 本集介绍如何在一个主命令后增强参数来增强主命令的功能， 我们可以把一个主命令下再加二级命令，甚至三级命令。 这样，我们可以把一些相关的功能都放在同一个主命令底下处理。
本视频中使用的代码：
function doPost(e){
var dataFromTelegram = {
"method": "post",
"payload": e.postData.contents
}
var body = JSON.parse(e.postData.contents);
body.message.chat.id = body.message.chat.id + '';
var payload = preparePayload(body);
var data = {
"method": "post",
"payload": payload
}
var dataToTelegram = {
"method": "post",
"payload": payload
}
UrlFetchApp.fetch("https://api.telegram.org/bot这里放机器人的token/", data);
}
function preparePayload(body){
var payload;
body.message.text = body.message.text.toLowerCase();
body.message.text = body.message.text.replace(/@temptestbot2/g, '');
var paras = body.message.text.trim().split(" ");
// remove empty strings
paras = paras.filter(function(para){
if (para){
return true;
}
});
if (body.message.text){
payload = {
"method": "sendMessage",
"chat_id": body.message.chat.id,
"text": "你好， 欢迎使用本机器人， 本机器人现在只认识颜色。",
}
if(body.message.text.indexOf("/help") === 0){
payload.text = "你好， 欢迎使用本机器人， 本机器人现在只认识颜色。";
return payload;
}
if(body.message.text.indexOf("/colors") === 0){
payload.text = "红\n黄\n蓝";
return payload;
}
if(body.message.text.indexOf("/list") === 0){
if (paras[1]){
switch (paras[1].toLowerCase()){
case "people":
if (paras[2]){
if ("JS神技能".toLowerCase().indexOf(paras[2]) >= 0){
payload.text = "JS神技能 - https://www.youtube.com/";
}
if ("悟空的日常".toLowerCase().indexOf(paras[2]) >= 0){
payload.text = "悟空的日常 - https://www.youtube.com/";
}
if ("YuFeng Deng".toLowerCase().indexOf(paras[2]) >= 0){
payload.text = "YuFeng Deng - https://www.youtube.com/";
}
} else {
payload.text = "JS神技能\n"
+ "悟空的日常\n"
+ "YuFeng Deng\n";
return payload;
}
break;
default:
payload.text = "红\n黄\n蓝";
break;
}
return payload;
} else {
payload.text = "JS神技能\n"
+ "悟空的日常\n"
+ "YuFeng Deng\n";
return payload;
}
}
payload = {
"method": "sendMessage",
"chat_id": body.message.chat.id,
"text": body.message.text,
}
}
else if (body.message.sticker){
payload = {
"method": "sendSticker",
"chat_id": body.message.chat.id,
"sticker": body.message.sticker.file_id
}
}
else if (body.message.photo){
array = body.message.photo;
text = array[1];
payload = {
"method": "sendPhoto",
"chat_id": body.message.chat.id,
"photo": text.file_id
}
}
else {
payload = {
"method": "sendMessage",
"chat_id": body.message.chat.id,
"text": "Try other stuff"
}
}
return payload
}
