我的问题是在这里我为每个API创建池以从MySQL数据库获取数据,在查询完成后我正在关闭池连接。如果我这样做,是否有任何性能问题。什么是实现这一目标的最佳方式。
请原谅我是否有任何问题,请提前致谢。
firstapi: async (req, resp) => {
let connection;
try {
connection = await mysql.createPool(db);
let firstquery = "first query goes here";
const [firstapidata] = await connection.execute(verlaufevortagquery);
resp.json(firstapidata);
} catch (error) {
resp.status(500).json({ message: "Failed to execute query", Error: error });
}
},
secondapi: async (req, resp) => {
let connection;
try {
connection = await mysql.createPool(db);
let secondquery = "second query goes here";
const [secondata] = await connection.execute(verlaufevortagquery);
resp.json(secondata);
} catch (error) {
resp.status(500).json({ message: "Failed to execute query", Error: error });
}
}
答案 0 :(得分:0)
相反,你可以保持连接打开,没有理由每次都打开它
let connection;
connection = await mysql.createPool(db);
firstapi: async (req, resp) => {
try {
use connection.execute here
} catch (error) {
resp.status(500).json({ message: "Failed to execute query", Error: error });
}
},
secondapi: async (req, resp) => {
try {
use connection.execute here
} catch (error) {
resp.status(500).json({ message: "Failed to execute query", Error: error });
}
}
