我的 node .js应用程序能够通过npm pg
模块与本地Postgres数据库协同工作.
以下是self signed certificate
错误的输出:

重现此错误的最简单方法是try 使用示例代码连接到 node 中.来自Heroku devcenter的js:
下面是导致self signed certificate
个错误的代码示例:
const connectionString = 'postgres://USERNAME:PASSWORD@HOST:PORT/DB_NAME';
const { Client } = require('pg');
const client = new Client({
connectionString: connectionString,
ssl: true
});
client.connect();
client.query('SELECT * FROM users;', (err, res) => {
if (err) throw err;
for (let row of res.rows) {
console.log(JSON.stringify(row));
}
client.end();
});
也许有人遇到过同样的问题,并且知道如何解决它.
提前感谢您的帮助.
