I'm new to telegram bot and node.js, I'm developing a simple bot that calls api urls to get json objects, but I've this error with a command.我是电报机器人和 node.js 的新手,我正在开发一个简单的机器人,它调用 api url 来获取 json 个对象,但是我在命令中遇到了这个错误。 This is the command's code:
这是命令的代码:
bot.onText(/\/fixtures/, (msg) => {
const chatId = msg.chat.id;
var out = "";
function myFunction(arr) {
var i;
for(i = 0; i < arr.length; i++) {
out += arr[i].name + "--";
}
}
request.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var myArr = JSON.parse(this.responseText);
myFunction(myArr);
}
};
request.open("GET", url, true);
request.send();
bot.sendMessage(chatId, out);
And this is full error:这是完整的错误:

You should send your message after your success ajax request reply. ajax请求回复成功后,您应该发送您的消息。 Move
bot.sendMessage(chatId, out);
移动
bot.sendMessage(chatId, out);
inside onReadyStateChange
callback:在
onReadyStateChange
回调中:
request.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var myArr = JSON.parse(this.responseText);
myFunction(myArr);
bot.sendMessage(chatId, out);
}
};
You will need to read the text gotten from the telegram bot.您将需要阅读从电报机器人获得的文本。 One way to do that is to:
一种方法是:
var out = msg.text;
So you will have this:所以你会有这个:
bot.onText(/\/fixtures/, (msg) => {
const chatId = msg.chat.id;
var out = msg.text;
function myFunction(arr) {
var i;
for(i = 0; i < arr.length; i++) {
out += arr[i].name + "--";
}
}
request.onreadystatechange =
function() {
if (this.readyState == 4 &&
this.status == 200) {
var myArr = JSON.parse(this.responseText);
myFunction(myArr);
}
};
request.open("GET", url, true);
request.send();
bot.sendMessage(chatId, out);
