Node Telegram Bot API return 错误请求：请求中没有照片

Question

有人用 Nodejs 写了一个 Telegram 机器人。要向用户发送图像，我使用以下命令：

bot.sendPhoto({
            chat_id: msg.chat.id,
            caption: 'Test caption',
            files: {
                photo: '../change-db-shop-url.png'
            }
        }, function (err, msg) {
            console.log(err);
            console.log(msg);
        });

显示此错误：

Unhandled rejection Error: 400 {"ok":false,"error_code":400,"description":"Bad Request: there is no photo in the request"}

你能帮帮我吗？

Answer 1

应该是：

bot.sendPhoto({
  chatId: msg.chat.id,
  caption: 'Test caption',
  photo: '../change-db-shop-url.png'
}, function(err, msg) {
  console.log(err);
  console.log(msg);
});

Answer 2

可能照片的 url 有误，换一张 url 试试，例如: https://upload.wikimedia.org/wikipedia/en/thumb/8/80/Wikipedia-logo-v2.svg/1122px-Wikipedia-logo-v2.svg.png

Answer 3

已解决：

var photo = __dirname+'/../Android.png';
bot.sendPhoto(msg.chat.id, photo, {caption: "I'm a bot!"});

如果您想从 url 发送文件：
