Javascript Wordpress admin ajax.php 400错误请求

事实证明，我正在制作一个Wordpress插件，其中我需要对Wordpress的文件“admin_AJAX.php”制作一个AJAX，但是在发送请求时，客户端给了我错误400（错误请求），我不明白是什么原因

捕获

Javascript:

$.post(window.dibibot.ajax_uri, {
    action: "dibibot_check_message_read",
    to: (window.dibibot.USER_KEYS.split(":")[1]).toString(),
    message_id: JSON.stringify(data.message)
}, function(response) {
    console.log(response);
});

<?php
    function dibibot_check_message_read() {
        global $wpdb;
        $conversation_guid = $_POST['to'];
        $message_id = json_decode($_POST['message_id'], true);

        $conversation = $wpdb->get_var("SELECT metadata FROM " . $wpdb->prefix . "dibibot_conversations WHERE guid = '".$conversation_guid."'");
        $conversation = maybe_unserialize($conversation);
        for ($j=0; $j < count($message_id) ; $j++) { 
            for ($i=0; $i < count($conversation); $i++) {
                if($conversation[$i]['id'] == $message_id[$j]) {
                    $conversation[$i]['status'] = 2;
                    break;
                }
            }
        }
        $result = $wpdb->update($wpdb->prefix . 'dibibot_conversations', [ "metadata" => maybe_serialize($conversation) ], [ "guid" => $conversation_guid]);
        echo $result ? 1 : 0;
        wp_die(); 
    }
?>

Ajax php函数：

$.post(window.dibibot.ajax_uri, {
    action: "dibibot_check_message_read",
    to: (window.dibibot.USER_KEYS.split(":")[1]).toString(),
    message_id: JSON.stringify(data.message)
}, function(response) {
    console.log(response);
});

<?php
    function dibibot_check_message_read() {
        global $wpdb;
        $conversation_guid = $_POST['to'];
        $message_id = json_decode($_POST['message_id'], true);

        $conversation = $wpdb->get_var("SELECT metadata FROM " . $wpdb->prefix . "dibibot_conversations WHERE guid = '".$conversation_guid."'");
        $conversation = maybe_unserialize($conversation);
        for ($j=0; $j < count($message_id) ; $j++) { 
            for ($i=0; $i < count($conversation); $i++) {
                if($conversation[$i]['id'] == $message_id[$j]) {
                    $conversation[$i]['status'] = 2;
                    break;
                }
            }
        }
        $result = $wpdb->update($wpdb->prefix . 'dibibot_conversations', [ "metadata" => maybe_serialize($conversation) ], [ "guid" => $conversation_guid]);
        echo $result ? 1 : 0;
        wp_die(); 
    }
?>

代码注册Ajax处理程序，但当您仅在wp\u enqueue\u脚本上运行它时，已经太晚了，wp\u Ajax\u nopriv\u钩子已经运行

$.post(window.dibibot.ajax_uri, {
    action: "dibibot_check_message_read",
    to: (window.dibibot.USER_KEYS.split(":")[1]).toString(),
    message_id: JSON.stringify(data.message)
}, function(response) {
    console.log(response);
});

<?php
    function dibibot_check_message_read() {
        global $wpdb;
        $conversation_guid = $_POST['to'];
        $message_id = json_decode($_POST['message_id'], true);

        $conversation = $wpdb->get_var("SELECT metadata FROM " . $wpdb->prefix . "dibibot_conversations WHERE guid = '".$conversation_guid."'");
        $conversation = maybe_unserialize($conversation);
        for ($j=0; $j < count($message_id) ; $j++) { 
            for ($i=0; $i < count($conversation); $i++) {
                if($conversation[$i]['id'] == $message_id[$j]) {
                    $conversation[$i]['status'] = 2;
                    break;
                }
            }
        }
        $result = $wpdb->update($wpdb->prefix . 'dibibot_conversations', [ "metadata" => maybe_serialize($conversation) ], [ "guid" => $conversation_guid]);
        echo $result ? 1 : 0;
        wp_die(); 
    }
?>

如果您在这里结束是因为收到400错误（错误请求），原因可能是在用户未登录时发出AJAX请求

您必须从更改代码

wp_ajax_my_action', 'my_action' ); 

到
