我想通过我的机器人发送PhotoMessage！但是套接字重新连接并且没有记录错误！

global.bot.send(pMsg, responder.peer);
// responder.reply(pMsg);

【解决方案1】：

这是因为您在pMsg 中没有正确设置fileSize。试试下面的代码，已经测试过了：

const SDK = require("balebot");
const BaleBot = SDK.BaleBot;
const PhotoMessage=SDK.PhotoMessage;

let bot = new BaleBot('token');

let _pic = {
    fileId: '-8485942782244354814',
    accessHash: '1533910422',
    name: '9312002.jpg',
    fileSize: '62379',
    mimeType: 'image/jpeg',
    fileStorageVersion: 1,
    ext_width: 349,
    ext_height: 456,
    width: 349,
    height: 456,
    thumb:'thumbnail'
};
const pMsg = new PhotoMessage(
    _pic.fileId, _pic.accessHash, _pic.name,
    _pic.fileSize, 'image/jpeg', "title",
    _pic.width, _pic.height, _pic.thumb
);
bot.hears(["/start"], (message, responder) => {
    bot.send(pMsg, responder.peer).then((res) => {
        console.log(res)
    }).catch((err) => {
        console.log(err)
    });
});

我发现了我的问题！当你上传文件到 Bale 服务器时，response 是一个 accessHash 和 fileId 的对象。 accessHash 是一个数字，而必须是 String！我将 accessHash 转换为字符串，它的工作。

bot.UploadFile(buf, "photo").then(response => {
    response.accessHash = response.accessHash + "";
    response.size = buf.length;
    response.base64 = base64data;
    response.width = dimensions.width;
    response.height = dimensions.height;
    store.set(_pic.key, response);
    store.save();
    store.writeFile();
}).catch(err => {
    console.log(err);
});
