Implementations§

Source§

impl DatabaseService

Source

pub fn build_database_url(config: &DatabaseConfig) -> String

构建数据库连接 URL

§安全性

使用 URL 编码确保特殊字符(如密码中的特殊字符)被正确编码

Source

pub async fn create_connection( config: &DatabaseConfig, schema: Option<&str>, options: Option<ConnectionOptions>, ) -> Result<DatabaseConnection, DatabaseError>

创建数据库连接(支持指定 schema)

Source

pub async fn init( config: &DatabaseConfig, options: Option<ConnectionOptions>, ) -> Result<DatabaseConnection, DatabaseError>

初始化数据库连接(使用配置中的默认 schema)

Source

pub async fn set_extra_float_digits( db: &DatabaseConnection, ) -> Result<(), DatabaseError>

设置 PostgreSQL extra_float_digits 参数

Source

pub async fn set_schema( db: &DatabaseConnection, schema: &str, ) -> Result<(), DatabaseError>

设置 PostgreSQL schema

§安全性

验证 schema 名称,防止 SQL 注入攻击

Source

pub async fn test_connection( db: &DatabaseConnection, ) -> Result<(), DatabaseError>

测试数据库连接

Source

pub fn validate_config(config: &DatabaseConfig) -> Result<(), DatabaseError>

验证数据库配置

§验证项
  • 主机地址不能为空
  • 端口必须在有效范围内(1-65535)
  • 数据库名称不能为空
  • 用户名不能为空(SQLite 除外)
  • 数据库类型必须支持
