我对使用Wordpress进行api调用很陌生，所以请耐心等待。

我有这个功能：

function foo() {

$userinfo = [
    "number" => "26246426",
    "secondnumber" => "43634643"
];

$api_url = \'https://api.url.com\';
$response = wp_remote_post( $api_url, array(
    // Set the Content-Type header.
    \'headers\' => array(
        \'Content-Type\' => \'application/json\',
    ),
    // Set the request payload/body.
    \'body\'    => json_encode( $userinfo ),
) );

$res_body = wp_remote_retrieve_body( $response );

echo $res_body;

die();
}

这很有效，我得到了回应。

现在，我要做的是向我的ajax发送一个动作中的响应，该响应位于php函数正下方的脚本中（一切都发生在插件文件中）

以下是我的行动

add_action(\'wp_ajax_add_foo\', \'foo\' );
add_action(\'wp_ajax_nopriv_add_foo\', \'foo\' );

我的ajax调用在函数下面的脚本标记中

var ajaxscript = { ajax_url : \'mywebsite.com/wp-admin/admin-ajax.php\' }


jQuery(document).ready(function($) {

        $.ajax ({
            url: ajaxscript.ajax_url,
            type: \'POST\',
            // dataType: \'application/json\',
            data: {
                // the value of data.action is the part AFTER \'wp_ajax_\' in
                // the add_action (\'wp_ajax_xxx\', \'yyy\') in the PHP above
                action: \'_add_foo\'
                // ANY other properties of data are passed to your_function()
                // in the PHP global $_REQUEST (or $_POST in this case)

                },
          success : function( response ){ console.log(response) },
          error : function(error){ console.log(error) }
            }) ;
});

我希望能得到$res\\u body变量，但我得到的是400。为什么会这样？

    data: {
            // the value of data.action is the part AFTER \'wp_ajax_\' in
            // the add_action (\'wp_ajax_xxx\', \'yyy\') in the PHP above
            action: \'_add_foo\'
            // ANY other properties of data are passed to your_function()
            // in the PHP global $_REQUEST (or $_POST in this case)

            },

var ajaxscript = { ajax_url : \'mywebsite.com/wp-admin/admin-ajax.php\' }

var ajax_url = "<?php echo admin_url(\'admin-ajax.php\'); ?>";
