Yii2：Rest POST 請求參數未到達

Question

早上好，

我在這個話題上沒有進一步了解，所以我在這里寫一個問題。

首先，我使用教程中的數據創建了一個數據庫表： https://www.yiiframework.com/doc/guide/2.0/en/start-databases

然后我使用上面的數據從該教程創建了 Rest Controller： https://www.yiiframework.com/doc/guide/2.0/en/

教程中的第一個示例 GET 請求工作正常，並為我提供了數據庫中的所有數據。 我的請求 URL: http://XX.XX12:XX90/country/

現在我們在嘗試通過 POST 請求在數據庫中創建一個新國家時遇到了我的錯誤。 當使用教程下方的 CURL 命令和我的測試數據時，我收到以下錯誤：

SQLSTATE[HY000]: General error: 1364 Field 'code' doesn't have a default value**strong text**

(
    [0] => HY000
    [1] => 1364
    [2] => Field 'code' doesn't have a default value
)

我從 rest api 的標准日志記錄說 POST Var 是空的，但為什么呢？ 我還測試了通過工具（郵遞員）發送 POST 請求，但我得到了同樣的錯誤。

$_GET = []

$_POST = []

$_FILES = []

$_COOKIE = []

$_SERVER = [....]

我的 Model：

<?php

namespace app\models;

use yii\db\ActiveRecord;

class Country extends ActiveRecord
{
}

我的 Controller：

<?php

namespace app\controllers;

use yii\rest\ActiveController;

class CountryController extends ActiveController
{
    public $modelClass = 'app\models\Country';
}

我的 CURL 請求：

curl -i -H "Accept:application/json" -H "Content-Type:application/json" \
    -XPOST "http://XX.X.X.12:XX90/countries/" \
    -d '{"code": "TEST", "name": "TestCountry", "population": 01}'

    $config['bootstrap'][] = 'debug';
    $config['modules']['debug'] = [

    $config['bootstrap'][] = 'gii';
    $config['modules']['gii'] = [
        'class' => 'yii\gii\Module',
        // uncomment the following to add your IP if you are not connecting from localhost.
        //'allowedIPs' => ['127.0.0.1', '::1'],
    ];
}

return $config;

建議？

您需要聲明使用 Rest API 的驗證規則

我的國家 Model 現在：

<?php

namespace app\models;

use yii\db\ActiveRecord;

class Country extends ActiveRecord
{

    public function rules()
    {
        return [
            [['code', 'name', 'population'], 'required']
        ];
    }
}
