主目录iris

    —— main.go

示例代码

main.go

//包主显示如何在您的Web应用程序中使用orm
//它只是插入一列并选择第一列。
package main

import (
    "time"
    "github.com/kataras/iris"
    "github.com/go-xorm/xorm"
    _ "github.com/mattn/go-sqlite3"
)
/*
    go get -u github.com/mattn/go-sqlite3
    go get -u github.com/go-xorm/xorm
    如果您使用的是win64并且无法安装go-sqlite3:
        1.下载:https://sourceforge.net/projects/mingw-w64/files/latest/download
        2.选择“x86_x64”和“posix”
        3.添加C:\Program Files\mingw-w64\x86_64-7.1.0-posix-seh-rt_v5-rev1\mingw64\bin
        到你的PATH env变量。
