大家做多级代理项目的时候怎么设计sql表？-灵析社区

1.用户表 CREATE TABLE users ( user_id INT PRIMARY KEY, username VARCHAR(50) NOT NULL, password VARCHAR(50) NOT NULL, email VARCHAR(50) NOT NULL ); 2.代理表 CREATE TABLE proxies ( proxy_id INT PRIMARY KEY, ip_address VARCHAR(50) NOT NULL, port INT NOT NULL, username VARCHAR(50), password VARCHAR(50), status ENUM('available', 'unavailable', 'expired') NOT NULL ); 3.代理关系表 CREATE TABLE proxy_users ( user_id INT, proxy_id INT, PRIMARY KEY (user_id, proxy_id), FOREIGN KEY (user_id) REFERENCES users(user_id), FOREIGN KEY (proxy_id) REFERENCES proxies(proxy_id) ); 4.流量表 CREATE TABLE traffic ( traffic_id INT PRIMARY KEY, user_id INT, proxy_id INT, traffic_type ENUM('http', 'https', 'ftp', 'telnet') NOT NULL, traffic_size INT NOT NULL, traffic_time TIMESTAMP NOT NULL, FOREIGN KEY (user_id) REFERENCES users(user_id), FOREIGN KEY (proxy_id) REFERENCES proxies(proxy_id) ); 5.日志表 CREATE TABLE access_logs ( log_id INT PRIMARY KEY, user_id INT, proxy_id INT, access_time TIMESTAMP NOT NULL, access_url VARCHAR(255) NOT NULL, access_result ENUM('success', 'failure') NOT NULL, FOREIGN KEY (user_id) REFERENCES users(user_id), FOREIGN KEY (proxy_id) REFERENCES proxies(proxy_id) ); 最后要根据你项目的具体需求进行调整
