Oracle DB connection with Node.js Getting "Error: Schema User name is not Set! Try Set Environment Variable NODE_ORACLEDB_USER."

Question

我已经安装了 Node JS 版本 12，从 github 克隆了 node-oracle 数据库。

我还设置了 OCI_LIB_DIR 中提到的路径 article。

module.exports = {
  user          : process.env.NODE_ORACLEDB_USER || "hr",

  // Get the password from the environment variable
  // NODE_ORACLEDB_PASSWORD.  The password could also be a hard coded
  // string (not recommended), or it could be prompted for.
  // Alternatively use External Authentication so that no password is
  // needed.
  password      : process.env.NODE_ORACLEDB_PASSWORD || abcd,

  // For information on connection strings see:
  // https://oracle.github.io/node-oracledb/doc/api.html#connectionstrings
  connectString : process.env.NODE_ORACLEDB_CONNECTIONSTRING || "jdbc:oracle:thin:@localhost:1521/orcl",

  // Setting externalAuth is optional.  It defaults to false.  See:
  // https://oracle.github.io/node-oracledb/doc/api.html#extauth
  externalAuth  : process.env.NODE_ORACLEDB_EXTERNALAUTH ? true : false
};

我已经在 SQL developer 中创建了一个基本连接，有帮助吗？

我已经在 node-oracledb 中安装了 npm 并设置了用户名，但是当我尝试运行命令 "npm test" 时，它给了我错误

Deeksha ~/Desktop/nodewithoracle/node-oracledb (master)
$ npm test

Answer 1

在开始之前将凭证环境变量设置为您的数据库凭证值 Node.js。错误消息说 NODE_ORACLEDB_USER 未设置。

或者，您可以直接在 getConnection() 调用中设置值：

connection = await oracledb.getConnection({ user: 'hr', password: 'welcome', connectString: 'localhost/orcl' });

但要小心硬编码密码。
使用有效的连接字符串； JDBC 连接字符串不可用（Node.js 不是 JDBC）。请参阅 node-oracledb 文档 JDBC and Oracle SQL Developer Connection Strings 以了解如何确定要使用的内容。根据您发布的内容，您应该只使用 localhost:1521/orcl.

节省一些时间，阅读 node-oracledb installation manual, the documentation, and the examples。
