wp_remote_post 响应正文受到保护

Question

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

下面的代码，我用来进行 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：

数组 ( [headers] => Requests_Utility_CaseInsensitiveDictionary 对象 ( [data:protected]

我正在本地主机中开发 WordPress 插件。如何解决这个错误。

更新：问题已通过以下代码解决。根据我的理解，问题在于以错误的方式向 API 发送参数。 感谢您帮助莎莉 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

这与响应主体受到“保护”无关。但是您没有获得预期的响应数据，因为请求正文不完整- 即它不包含$args(eg )中的数据AppId。

因为$args是请求体；所以它应该wp_remote_post()像这样传递：

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

请参阅https://codex.wordpress.org/Function_Reference/wp_remote_post#Parameters

固定代码

（为了清晰起见，重新缩进；还有其他变化）

// 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 );

附加说明

这里，$responceData将是一个array，因为您将第二个参数设置为true：

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

因此，如果您想$responceData成为object，则只需省略第二个参数即可：

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