開啟debug調試模式(正式上線建議關閉)

config.php

// 應用調試模式

'app_debug' => true,

設置輸出類型

index.php

namespace app\index\controller;

class Index

{

public function index()

{

$data = ['name' => 'steven', 'age' => 24];

return json(['code' => 0, 'msg' => '操作成功', 'data' => $data]);

}

}

或者config.js

// 默認輸出類型, 可選html,json xml ...

'default_return_type' => 'json',

獲取請求參數

引入使用: use think\Request;

namespace app\index\controller;

use think\Request;

class Index {

public function index() {

$res = Request::instance();

// 注意連接字符串用'.',為不是'+'

echo '請求方法: ' . $res->method() . '

---

';

echo '訪問地址: ' . $res->ip() . '

---

';

echo '請求參數: ';

dump($res->param());

echo '請求參數(僅包含id): ';

dump($res->only(['id']));

echo '請求參數(排除id): ';

dump($res->except(['id']));

}

}

判斷請求類型

if ($res->isGet()) echo '這是GET方法';

if ($res->isPost()) echo '這是POST方法';

驗證參數數據

use think\Validate;

$rules = [

'name' => 'require',

'age' => 'number|between:0,120',

'email' => 'email'

];

$msg = [

'name.require' => '姓名不能為空',

'age.number' => '年齡必須為數字類型',

'age.between' => '年齡范圍1-120',

'email' => '郵箱格式不正確'

];

// 注意post后有個點

$data = input('post.');

$validate = new Validate($rules, $msg);

$res = $validate->check($data);

if(!$res){

echo $validate->getError();

}
