wordpress - wp_remote_post 响应体被保护

Question

我已经使用 wp_remote_post 进行了 API 调用，并尝试使用 wp_remote_retrieve_body 检索正文。但响应仅显示标题，正文受到保护。

在下面的代码中，我曾经进行过 API 调用。

$args = array(
                'LocationId' => $loc_id,
                'AppId' => $app_id
               );
    $response = wp_remote_post( 'https://www.apiurl.com?APIKEY='."$api_key".'', $args );

$responceData = json_decode(wp_remote_retrieve_body( $response ), TRUE );
print_r($response);

打印的响应(只是开始的数据)是:

Array ( [headers] => Requests_Utility_CaseInsensitiveDictionary Object ( [data:protected]

我正在本地主机上开发 wordpress 插件。如何解决这个错误。

更新:问题已通过以下代码解决。据我了解，问题在于以错误的方式向 API 发送参数。 感谢帮助 Sally Cj

$postData = array(
    'LocationId' => $loc_id,
    'AppId' => $app_id,
);
$context = array(
        'method' => 'POST',
        'headers' => "Authorization:\r\n".
            "Content-Type: application/json\r\n",
        'httpversion' => '1.0',
        'redirection' => 5,
        'timeout' => 60,
        'blocking' => true,
        'body' => json_encode($postData)
    );
            $response = wp_remote_post( 'apiurl.com?APIKEY='."$api_key".'', $context);
            $currency = wp_remote_post( 'apiurl.com?APIKEY='."$api_key".'', $context);

if ( is_wp_error( $response ) ) {
   $error_message = $response->get_error_message();
   echo "Something went wrong: $error_message";
} else {
    $responceData = json_decode(wp_remote_retrieve_body($response), true);
    $currencyData = json_decode(wp_remote_retrieve_body($currency), true);

问题

不是响应主体被“保护”。但是您没有得到预期的响应数据，因为请求正文不完整 — 即它不包含$args 中的数据(例如 AppId)。

因为 $args 是请求主体；所以它应该像这样传递给 wp_remote_post():

$response = wp_remote_post( 'https://www.apiurl.com?APIKEY='."$api_key".'', array(
    'body' => $args
) );

参见 https://codex.wordpress.org/Function_Reference/wp_remote_post#Parameters

固定代码

(为清楚起见重新缩进；还有其他更改)

// Request body.
$body = array(
    'LocationId' => $loc_id,
    'AppId'      => $app_id
);
$response = wp_remote_post( 'https://www.apiurl.com?APIKEY='."$api_key".'', array(
    'body' => $body
) );

// Response body.
$body = wp_remote_retrieve_body( $response );

// On success (i.e. `$body` is a valid JSON string), `$responceData` would be an
// `ARRAY`.
$responceData = ( ! is_wp_error( $response ) ) ? json_decode( $body, true ) : null;
var_dump( $responceData );

补充说明

在这里，$responceData 将是一个数组，因为您将second 参数设置为true:

$responceData = json_decode(wp_remote_retrieve_body( $response ), TRUE );

因此，如果您希望 $responceData 成为一个 object，则只需省略第二个参数:

$responceData = json_decode(wp_remote_retrieve_body( $response ) );
//$responceData = json_decode(wp_remote_retrieve_body( $response ), false ); // equivalent to above

参见 PHP manual for json_decode()了解更多详情。
