修改.env數(shù)據(jù)庫配置
APP_DEBUG = true
[APP]
DEFAULT_TIMEZONE = Asia/Shanghai
[DATABASE]
TYPE = mysql
HOSTNAME = 10.10.90.139
DATABASE = tp6stu01
USERNAME = root
PASSWORD = password
HOSTPORT = 3306
CHARSET = utf8
DEBUG = true
PREFIX = tp_
[LANG]
default_lang = zh-cn
測試環(huán)境下是可以使用的，但是到了線上建議配置到config下database.php
// 數(shù)據(jù)庫類型
'type' => env('database.type', 'mysql'),
// 服務(wù)器地址
'hostname' => env('database.hostname', '10.10.90.139'),
// 數(shù)據(jù)庫名
'database' => env('database.database', 'tp6stu01'),
// 用戶名
'username' => env('database.username', 'root'),
// 密碼
'password' => env('database.password', 'password'),
// 端口
'hostport' => env('database.hostport', '3306'),
// 數(shù)據(jù)庫連接參數(shù)
'params' => [],
// 數(shù)據(jù)庫編碼默認(rèn)采用utf8
'charset' => env('database.charset', 'utf8'),
// 數(shù)據(jù)庫表前綴
'prefix' => env('database.prefix', 'tp_'),
可以通過刪除改變.env 的配置，或刪除.env 來驗(yàn)證 database 的執(zhí)行優(yōu)先級，經(jīng)過驗(yàn)證可知:.env>database.php
//default 表示設(shè)置默認(rèn)的數(shù)據(jù)庫連接，這里用的是connections下mysql的配置
'default' => env('database.driver', 'mysql'),
新建DataTest.php
<?php
namespace app\controller;
use think\facade\Db;
class DataTest
{
public function index()
{
$user = Db::table('tp_user')->select();
//也可以切換為name就不用寫前綴了
//$user = Db::name('user')->select();
return json($user);
}
}
connections 配置數(shù)據(jù)庫連接信息，可以是多個(gè)數(shù)據(jù)庫，便于切換，新建demo配置
'demo' => [
// 數(shù)據(jù)庫類型
'type' => env('database.type', 'mysql'),
// 服務(wù)器地址
'hostname' => env('database.hostname', '10.10.90.139'),
// 數(shù)據(jù)庫名
'database' => env('database.database', 'tp6stu02'),
// 用戶名
'username' => env('database.username', 'root'),
// 密碼
'password' => env('database.password', 'password'),
// 端口
'hostport' => env('database.hostport', '3306'),
// 數(shù)據(jù)庫連接參數(shù)
'params' => [],
// 數(shù)據(jù)庫編碼默認(rèn)采用utf8
'charset' => env('database.charset', 'utf8'),
// 數(shù)據(jù)庫表前綴
'prefix' => env('database.prefix', 'tp_'),
// 數(shù)據(jù)庫部署方式:0 集中式(單一服務(wù)器),1 分布式(主從服務(wù)器)
'deploy' => 0,
// 數(shù)據(jù)庫讀寫是否分離 主從式有效
'rw_separate' => false,
// 讀寫分離后 主服務(wù)器數(shù)量
'master_num' => 1,
// 指定從服務(wù)器序號
'slave_no' => '',
// 是否嚴(yán)格檢查字段是否存在
'fields_strict' => true,
// 是否需要斷線重連
'break_reconnect' => false,
// 監(jiān)聽SQL
'trigger_sql' => env('app_debug', true),
// 開啟字段緩存
'fields_cache' => false,
],
新建demo方法
public function demo()
{
$demo = Db::connect('demo')->table('tp_user')->select();
return json($demo);
}
模型初探
在 app 目錄下創(chuàng)建一個(gè) model 目錄，并創(chuàng)建 User.php 的模型類
<?php
namespace app\model;
use think\Model;
class User extends Model
{
}
datatest.php添加getUser方法文章來源：http://www.zghlxwxcb.cn/news/detail-795293.html
use app\model\User;
public function getUser()
{
$user = User::select();
return json($user);
}
數(shù)據(jù)庫默認(rèn)鏈接的default下的配置就是mysql，現(xiàn)在想切換為demo，需要給User添加一個(gè)屬性文章來源地址http://www.zghlxwxcb.cn/news/detail-795293.html
<?php
namespace app\model;
use think\Model;
class User extends Model
{
protected $connection = 'demo';
}
到了這里，關(guān)于thinkphp學(xué)習(xí)06-連接數(shù)據(jù)庫與模型初探的文章就介紹完了。如果您還想了解更多內(nèi)容，請?jiān)谟疑辖撬阉鱐OY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
