php - 尝试在 woocommerce 中触发 webhook 后不发送电子邮件的原因跟踪错误

Question

我试图了解为什么有时 webhook 似乎会触发，而有时在 Woocommerce 购买后却不会触发。

有一个自定义插件应该添加到 custom topic我对 woocommerce 插件 webhook 的理解是添加了以下代码(我将把整个代码放在下面)

function add_new_webhook_topics( $topics ) {
    // New topic array to add to the list, must match hooks being created.
    $new_topics = array( 
        'order.gift_card' => __( 'Order Gift Card', 'woocommerce' ),
        );
    return array_merge( $topics, $new_topics );
 }
 add_filter( 'woocommerce_webhook_topics', 'add_new_webhook_topics' );

有两个文件，一个是插件，我只能说它目前所做的就是将自定义主题添加到 webhook 下拉选项中，这样我们就可以在成功下订单时触发 webhook。然而，有时它会触发 webhook，但据我所知，有时不会。我之所以这么说是因为在将有效负载发送到礼品卡平台然后返回礼品卡并发送电子邮件之后，应该从 webhook 触发一封电子邮件。

首先是插件PHP代码。我认为额外的排队脚本是计划中的功能，但仍不确定。

<?php

 function get_parent_grouped_id( $children_id ){
     global $wpdb;

         WHERE meta_key = '_children' AND meta_value LIKE '%$children_id%'");
     // Will only return one product Id or false if there is zero or many
     return sizeof($results) == 1 ? reset($results) : false;

现在我不知道这是否实际上是向礼品卡平台发送有效负载，或者 webhook 是否正在完成所有这些工作。我很困惑，因为礼品卡平台在 webhook 和这个插件中被调用，希望有人可以帮助澄清这个插件中发生的事情，而不是基于主题触发 webhook。

这是网络钩子(Hook)

现在这是我的问题所在。我不知道 mail($to, $subject, $message, $headers); 的原因。永远不会被发送是因为 webhook 未能提交到礼品卡服务器并且在礼品卡服务器端出现错误，或者如果是这个 webhook 未能发送电子邮件。或者，如果这个 webhook 从未被触发。

现在帮助调试 如果此 webhook 的邮件功能从未发送过，它发送大约一半的时间我可以通过将订单状态从处理更改为已完成来发送它。但是，这应该只适用于内部，我们确实希望自动发送礼品卡信息，但是我希望有一种方法可以通过自定义操作从 woocommerce 的订单页面重新发送此 webhook。像一个按钮或者说重新发送礼品卡电子邮件的东西。

那么我想了解的真正有效载荷在哪里提交到礼品卡服务器，在 webhook 中还是在插件中？ 为什么webhook电子邮件只提交一半，然后当我在woocommerce中更改订单状态时会提交另一半。

这里也是 JS 脚本，但我认为它们目前没有做任何事情。

check-balance.js

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

  // checks card balance
  $('.gi-check-balance').submit(function() {

    var gx_card_number = $(this).find('[name=card-number]').val()
    var gx_card_pin = $(this).find('[name=card-pin]').val()

    $.ajax({
      url: gi_check_balance.ajax_url,
      type: 'post',
      data: {
        action: 'gi_check_balance',
        gx_card_number: gx_card_number,
        gx_card_pin: gx_card_pin
      },

        //$('.gi-check-balance-result').text(JSON.stringify(response))
        $('.gi-check-balance-result').show()
      }
    })

    return false

  })

})

安全注册.js

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

  // registers gift card
  $('.gi-secure-register').submit(function() {

    var gx_register_amount = $(this).find('[name=register-amount]').val()

    $.ajax({
      url: gi_secure_register.ajax_url,
      type: 'post',
      data: {
        action: 'gi_secure_register',
        gx_register_amount: gx_register_amount
      },
      dataType: 'json',
      success: function(response) {
        //$('.gi-secure-register-result').html('Reference Number: ' + response['result'][2] + '<br>' + 'Card Number: ' + response['result'][3] + '<br>' + 'Card Amount: ' + response['result'][4])
        $('.gi-secure-register-result').text(response)
        $('.gi-secure-register-result').show()
      }
    })

    return false

  })

Answer 1

在 中检查您的日志输出第 86 行 警告 以。。开始:

file_get_contents(): Failed to enable crypto...

该消息表明您使用安全连接，因此请尝试将以下内容添加到您的请求 header 中。

    $options = array(
      'ssl'=>array(
        'verify_peer'=>false,
        'verify_peer_name'=>false
      ),
      'http' => array(
        'method' => 'POST',
        'header' => 'Content-Type: application/json',
        'content' => json_encode( $data_modified )
      )
    );

另外最好使用 empty()在检查 $result

    if ( empty($result) ) {
      $result = file_get_contents( $gx_post_url_2, false, $context );
    }

编辑:因为不验证对等点是不安全的。试试下面的，也看看 SSL context options了解更多信息。

    $options = array(
      'ssl'=>array(
        'verify_peer'=>true,
        'verify_peer_name'=>true,
        'cafile'=>'path/to/cafile.pem',
        'CN_match'=>'demo.com',
