mysql - Node.js - 插入添加 0 而不是字符串

Question

我正在尝试使用 node.js 插入一些数据。我通过 npm 安装了 MySQL 支持，但似乎仍然无法使用 INSERT INTO 输入正确的字符串。（数据库中的行类型是 tinytext，字符串小于 255 个字符。）

这是我的代码 https://hastebin.com/komikahatu.http

预期的输出是它插入参数（/name 捕获的内容）和执行命令的用户的用户名（/name）。

console.log('Dirname: ' + __dirname);

const bot = require('../core.js');
bot.on("polling_error", (msg) => console.log(msg));

var config = require('../config.json');

var mysql = require('mysql');
var sqlhost = config.sql.host;
var sqluser = config.sql.user;
var sqlpass = config.sql.password;
var sqldb = config.sql.database;

var con = mysql.createConnection({
    host: sqlhost,
    user: sqluser,
    password: sqlpass,
    database: sqldb
});

bot.onText(/\/name (.+)/, (msg, match) => {
    const chatId = msg.chat.id;
    // 'msg' is the received Message from Telegram
    // 'match' is the result of executing the regexp above on the text content
    // of the message

    let username;
    const name = match[1].toString(); // the captured name

    if(msg.from.username !== ''){
        username = msg.from.username;
    }

    var setnickname = {
      username_: username,
      nickname_: name
    };

    var sql = con.query('INSERT INTO nickname_data VALUES (?)', setnickname, function (err, result){
        console.log(sql.sql);
        if (err) {
            console.error(err)
            return;
        }
        console.error(result);
    });

    if (name !== "undefined") {
        bot.sendMessage(chatId, 'Welcome ' + name + '!');
        // bot.sendMessage(chatId, 'Welcome ' + msg.from.name + '!');
        // config.information.normalusername = name;
    }
});

试试这个

var setnickname = {
  username_: String(username),
  nickname_: String(name)
};

var sql = con.query('INSERT INTO nickname_data SET ?', setnickname, function (err, result){
    console.log(sql.sql);
    if (err) {
        console.error(err)
        return;
    }
    console.error(result);
});

VALUES在查询中使用关键字时，您还可以将第二个参数作为数组传递。类似

var setnickname = [String(username),String(name)];

var sql = con.query('INSERT INTO nickname_data(username_,nickname_) VALUES (?,?)', setnickname, function (err, result){
    console.log(sql.sql);
    if (err) {
        console.error(err)
        return;
    }
    console.error(result);
});
