Question

我遇到错误查询Clickhouse数据库时出现错误。

const { ClickHouse } = require('clickhouse');
const clickhouse = new ClickHouse({
debug: false,
basicAuth: {
username: 'username',
password: 'password',
},
});
clickhouse.query('SHOW DATABASES;').exec((err, rows) => {
console.log(err);
console.log(rows);
})

-> ====输出=====

[nodemon]起始节点index.js 错误：getaddrinfo ENOTFOUND http 在GetAddrInfoReqWrap.onlookup [as oncomplete]（dns.js：60：26）{ errno：“ ENOTFOUND”，代码：“ ENOTFOUND”， syscall：“ getaddrinfo”，主机名：“ http” } 未定义

Answer 1

您应指定托管Clickhouse的主机和端口

const { ClickHouse } = require('clickhouse');
const clickhouse = new ClickHouse(url: process.env.DATABASE_HOST,
    port: parseInt(process.env.DATABASE_PORT),
    debug: false,
    basicAuth: {
        username: "username",
        password: "password"
    },
    isUseGzip: false,
    config: {
        session_timeout: 60,
        output_format_json_quote_64bit_integers: 0,
        enable_http_compression: 0
    });
clickhouse.query('SHOW DATABASES;').exec((err, rows) => {
console.log(err);
console.log(rows);
})

无法使用Node.js查询Clickhouse数据库
