在 Yii2 中获取 JSON 格式的响应

2022-01-07 00:00:00 json php yii2 yii2-advanced-app

我正在尝试将响应数组转换为 JSON 格式.我已经尝试了在 SO 和其他网站上发布的所有答案，例如 web1,web2 添加 header('内容类型:application/json') 然后 echo json_encode($data,JSON_PRETTY_PRINT);但我总是以文本格式获得输出.有人能帮我解决这个问题吗.

I'm trying to convert and array of response into JSON format. I have tried all the answers that were posted on SO and other websites like web1,web2 adding header('Content-Type: application/json') and then echo json_encode($data,JSON_PRETTY_PRINT); But I'm always getting the output in text format. Can some one help me in solving this.

助手类:

public static function renderJSON($data) {
    header('Content-Type: application/json');
    echo json_encode($data,JSON_PRETTY_PRINT);
}

我的控制器:

if ($model->login()) {
    $user =  User::findByUsernameOrEmail($request->post('username'));
    $userArray = ArrayHelper::toArray($user);
    Helpers::renderJSON($userArray);

我尝试打印 userArray，它看起来像这样:

I tried to printing the userArray and it looks like this:

Array
(
    [name] => abc
    [lastname] => xyz
    [username] => test_test
)

Json 输出:(html/text)

Json output: (html/text)

{
    "name": "abc",
    "lastname": "xyz",
    "username": "test_test"
}

推荐答案

设置

Yii::$app->response->format = yiiwebResponse::FORMAT_JSON;

在return之前的某个控制器的动作中.

in the controller's action somewhere before return.
