我的服务器可以打开，但我的数据库没有创建表用户，我不知道我的代码问题，我所做的只是根据蒸汽文件。
我在Config + Setup.swift中添加了准备和addProvider

这是我的模型user.swift
import MySQLProvider
final class Users: Model {
var usename: String
var passWord: Int
let storage = Storage()
init(row: Row) throws {
usename = try row.get("name")
passWord = try row.get("passWord")
}
init(usename: String, passWord: Int) {
self.usename = usename
self.passWord = passWord
}
func makeRow() throws -> Row {
var row = Row()
try row.set("usename", usename)
try row.set("passWord", passWord)
return row
}
}
extension Users: Preparation {
static func prepare(_ database: Database) throws {
try database.create(self) { user in
user.id()
user.string("usename")
user.int("passWord")
}
}
static func revert(_ database: Database) throws {
try database.delete(self)
}
}
mysql.json
{
"hostname": "localhost",
"user": "root",
"password": "123456",
"database": "User"
}
我的Config + Setup.swift
extension Config {
public func setup() throws {
// allow fuzzy conversions for these types
// (add your own types here)
Node.fuzzy = [Row.self, JSON.self, Node.self]
try setupProviders()
try setupPreparations()
}
/// Configure providers
private func setupProviders() throws {
try addProvider(FluentProvider.Provider.self)
try addProvider(MySQLProvider.Provider.self)

/// Add all models that should have their
/// schemas prepared before the app boots
private func setupPreparations() throws {
preparations.append(Post.self)

我不知道问题出在哪里，所以我真的希望你能帮我解决这个问题

您是否已将模型添加到准备工作中？
答案 1 :(得分：0)
从它创建数据库的证据，但你找不到它，它很可能使用默认的，基于内存的SQLite。查看fluent.json并更改driver设置，如下所示：
"//": "The underlying database technology to use.",
"//": "memory: SQLite in-memory DB.",
"//": "sqlite: Persisted SQLite DB (configure with sqlite.json)",
"//": "Other drivers are available through Vapor providers",
"//": "https://github.com/search?q=topic:vapor-provider+topic:database",
"driver": "mysql",
您也没有提及Driver + Config.swift文件，其示例如下：
import URI
import Vapor
import Fluent
import MySQLDriver
extension MySQLDriver.Driver: ConfigInitializable {
/// Creates a MySQLDriver from a `mysql.json`
/// config file.
///
/// The file should contain similar JSON:
///
/// {
/// "hostname": "127.0.0.1",
/// "user": "root",
/// "password": "",
/// "database": "test",
/// "port": 3306, // optional
/// "flag": 0, // optional
/// "encoding": "utf8" // optional
/// }
///
/// Optionally include a url instead:
///
/// {
/// "url": "mysql://user:pass@host:3306/database"
/// }
