php - 什么时候根据 woocomerce 事件触发我的发布请求，以及如何控制台我的 php 代码以便我可以调试

问题描述

我在此代码传递给我之前发布了此代码，但这次我有一个不同的问题。我们正在与一家名为 GiveX 的公司进行集成，该公司给我的文档很少。雇用我的公司必须签署保密协议，所以我认为我不能透露他们向我们透露的大部分文件。我将尝试尽可能清楚地说明我想要实现的目标。我将把我所有的代码放在我的问题下面，并在 Wordpress 中命名文件的标题。

  1. 如何控制台记录例如文件$result中的gi_check_balance()函数integrate.php？我想知道的是 giveX 发回给我们的是什么。现在，即使这个函数正在向postgiveX 发送请求，我什至无法分辨。我应该在哪里看到这个安慰？在订单完成页面上？或在某处的一些日志中？
  2. 这add_action( 'wp_ajax_gi_check_balance', 'gi_check_balance' );条线是做什么的？我看到在 Wordpress 文档add_action中是一个在某个点触发的钩子，第一个值应该是 a string，第二个是 a 函数，我认为这是真的，但是创建这个钩子有什么意义，我不明白字符串在其他任何地方引用的第一个值，那么它是如何触发的？或者该函数何时运行，或者只是给它一个string名称和一个函数允许该函数运行？
  3. 同样有两个函数gi_check_balance()，gi_secure_register() 我怎么知道它们什么时候被触发？这些函数如何连接到check-balance.js文件和secure-register.js文件（现在我对gi_secure_register()函数的理解是它仅用于测试目的，我知道的唯一区别是在post请求中发送的代码标记为method一个是904和一个是994他们应该做不同的事情，但是通过阅读 giveX 文档我无法真正分辨出区别。
  4. 现在我知道还有一个 webhook，它似乎是基于integrate.php文件中定义的 woocommerce 中的自定义主题运行的。这个网络钩子似乎也发出了一个 post 请求给 giveX url，现在我无法理解为什么我们会发出 3 次 post 请求，一个在integrate.php插件文件本身，一个在webhook.php文件中，另一个在任一js文件。我知道有人很难为我确定这一点，但如果我能知道woocommerce 完成订单中的哪些场景，这些发布请求将被解雇？这将帮助我理解为什么会有三个不同的。
  5. webhook 正在发送的这部分电子邮件<b>Card Number:</b> ' . $response->result[3] . '<br /> <b>PIN:</b> ' . $response_reference[1] . '<br /> <b>Card Amount:</b> ' . $response->result[4] . '<br /> <b>Reference Number:</b> ' . $response_reference[0] . '</p>'当前在电子邮件中返回空变量。我想弄清楚为什么 giveX 不发回数据？我希望能够在某个地方控制台记录这个结果，我可以看到从 giveX 返回的任何错误。
  6. 所以基本上，当基于 woocommerce/wordpress 中的事件触发某些功能时，我希望得到一些帮助。另外我想知道哪些post请求实际上被解雇了，因为我认为我们只需要发送一个请求给 giveX 即可订购这些礼品卡购买。

好的，这是代码（非常感谢提前:)

更新

首先注意到的错误。看起来因为我在本地主机上，所以我被 https 连接拒绝了？现在我对 ssl 知之甚少，我将如何在本地工作。我还需要从我发送请求的 url 进一步的东西吗？

[22-Nov-2019 02:59:00 UTC] PHP Warning:  file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages:
error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed in /Users/anderskitson/Local Sites/river-cafe/app/public/wp-content/plugins/givex-integrate/webhook.dev.php on line 94

上面的错误在这里解决了https://stackoverflow.com/a/58924492/2949184并解决了我遇到的主要问题。

标签： phpwordpresswoocommercewebhooks

解决方案

  1. 当谈到控制台日志时，我使用error_log();并查看 PHP 错误日志文件。见https://www.loggly.com/ultimate-guide/php-logging-basics/

  2. 当我想知道在哪里使用了钩子时，我会使用第一个字符串，'wp_ajax_gi_check_balance'然后在 *.php 文件中搜索整个网站（如果我知道在哪里查找，则搜索更少）并查找显示do_action('wp_ajax_gi_check_balance'....

我稍后会发布更多。

更新

我意识到我对你其他问题的了解并不比你多。我认为至少错误记录可以让您进一步了解它的工作原理。我要睡觉了，但我明天可能会再检查一次，以防你有任何更新。

更新 2

关于您的 SSL 错误：file_get_contents(): SSL operation failed with code 1, Failed to enable crypto

您是否尝试自己搜索错误？
