无法在 Wordpress 中使用 REST API 获得响应

Can't get response using REST API in Wordpress

更新:修复在答案中!

请帮忙!

我想使用 RapidApi 中的 Instgram api。这就是 RapidAPI 显示为 PHP 片段的内容:

<?php

$request = new HttpRequest();
$request->setUrl('https://instagram47.p.rapidapi.com/public_user_posts');
$request->setMethod(HTTP_METH_GET);

$request->setQueryData([
    'userid' => '1718924098'
]);

$request->setHeaders([
    'x-rapidapi-key' => ' ***************** ',
    'x-rapidapi-host' => 'instagram47.p.rapidapi.com'
]);

try {
    $response = $request->send();

    echo $response->getBody();
} catch (HttpException $ex) {
    echo $ex;
}

这是我的代码在 functions.php 中的样子:

function get_instaPosts(){
    $request = wp_remote_retrieve_body( wp_remote_get( 'https://instagram47.p.rapidapi.com/user_posts', array(
            'headers' => array(
                "content-type" => "application/json",
                'userid' => '1718924098',
                'x-rapidapi-key' => 'INSTA_APIKEY',
                'x-rapidapi-host' => 'instagram47.p.rapidapi.com'
            ),
            'body' => array()
            )
        ));

    $response_code = wp_remote_retrieve_response_code($response);
    $body = wp_remote_retrieve_body($response);

    if( 401 === $response_code) {
        echo "<pre>";
        print_r("Unauthorised access");
        echo "</pre>";
    }

    if( 200 !== $response_code) {
        echo "<pre>";
        print_r("Error in pinging API");
        echo "</pre>";
    }

    if( 200 === $response_code) {
        echo "<pre>";
        print_r($body);
        echo "</pre>";
    }
}

但它始终打印在 if (200!==...) 语句中定义的 "Error in pinging API"。打印 $response 在两者之间:

[body] => {"message":"Missing required parameters"}

最后,因为他们给了你一个秘密的 API 密钥,像这样将实际密钥保存为 wp-config 中的变量并稍后仅使用 INSTA_APIKEY 引用它是一个好习惯吗没能做到 public:

/** API key for RapidApi Insta */
define( 'INSTA_APIKEY', '***************' );

非常感谢你们,你们不知道这个平台对我有多大帮助。 :D

修复: 在 functions.php:

function get_instaPosts(){
    $userid = ' ** insta userid here ** ';
    $first = '2';
    $after = ' ** the after code here ** ';
    $response = wp_remote_get( "https://instagram40.p.rapidapi.com/account-medias?userid=$userid&first=$first&after=$after", array(
            'headers' => array(
                'x-rapidapi-key' => ' ** secret key ** ',
                'x-rapidapi-host' => 'instagram40.p.rapidapi.com'
                )
            )
        );
        

    $response_code = wp_remote_retrieve_response_code($response);
    $body = wp_remote_retrieve_body($response);
    $decode = json_decode( $body, true );
