我的 config.php Heroku 应用代码和 mysql 代码出错
Error in my config.php code for Heroku app and mysql
我正在为 PHP 使用 Heroku。我查看了我的 Heroku 日志并在我的 config.php 代码中发现了错误。我正在为我的编码组合制作一个 spotify 克隆，我用 xampp、apache、mysql 成功制作了它。但现在我需要展示它并且我必须使用 Heroku，因为它是免费且安全的。我在 Heroku 中添加了 cleardb mysql 的附加组件并连接了 MySQL workbench 并转储了 SQL。但是 运行 我在 heroku 上的应用程序出现此错误，“此页面无法正常工作 nowslotifyhokole.herokuapp.com 目前无法处理此请求。
HTTP 错误 500
我的配置php代码：
<?php
$url = parse_url(getenv("mysql://bde1900971353c:2b4ac360@us-cdbr-east-05.cleardb.net/heroku_d347ebb2241490f?reconnect=true"));
$server = "us-cdbr-east-05.cleardb.net";
$username = "bde1900971353c";
$password = "2b4ac360";
$db = substr("heroku_d347ebb2241490f", 1);
$conn = new mysqli($server, $username, $password, $db);
?>

在你做任何其他事情之前，rotate those credentials.将它们从你的问题中编辑出来是不够。您已将它们发布到网上，它们将永远受到损害。
使用 getenv() for credentials is so you don't have to include them in your source code. The argument to getenv() shouldn't be your database URL; it should be the name of an environment variable 的全部意义在于 包含 您的数据库 URL.
The ClearDB add-on sets such a variable for you: CLEARDB_DATABASE_URL.
<?php
$url = parse_url(getenv("CLEARDB_DATABASE_URL"));
不幸的是，MySQLi 看起来并不知道如何直接通过 URL 进行连接，因此您可以将 URL 分开并将各个值传递给构造函数。
但是您需要从刚刚从环境中加载的 URL 而不是 hard-coding 值来执行此操作。您已经在 URL 字符串上调用了 parse_url()，因此您应该已经拥有所需的内容。
像这样的东西应该可以工作：
$server = $url["host"];
$username = $url["user"];
$password = $url["pass"];
$db = substr($url["path"], 1);
$conn = new mysqli($server, $username, $password, $db);
抱歉，我刚刚弄明白为什么它不起作用。我没有部署到主分支。我必须先部署它。
我正在为 PHP 使用 Heroku。我查看了我的 Heroku 日志并在我的 config.php 代码中发现了错误。我正在为我的编码组合制作一个 spotify 克隆，我用 xampp、apache、mysql 成功制作了它。但现在我需要展示它并且我必须使用 Heroku，因为它是免费且安全的。我在 Heroku 中添加了 cleardb mysql 的附加组件并连接了 MySQL workbench 并转储了 SQL。但是 运行 我在 heroku 上的应用程序出现此错误，“此页面无法正常工作 nowslotifyhokole.herokuapp.com 目前无法处理此请求。 HTTP 错误 500

在你做任何其他事情之前，rotate those credentials.将它们从你的问题中编辑出来是不够。您已将它们发布到网上，它们将永远受到损害。
使用 getenv() for credentials is so you don't have to include them in your source code. The argument to getenv() shouldn't be your database URL; it should be the name of an environment variable 的全部意义在于 包含 您的数据库 URL.
The ClearDB add-on sets such a variable for you: CLEARDB_DATABASE_URL.
<?php
$url = parse_url(getenv("CLEARDB_DATABASE_URL"));
不幸的是，MySQLi 看起来并不知道如何直接通过 URL 进行连接，因此您可以将 URL 分开并将各个值传递给构造函数。
但是您需要从刚刚从环境中加载的 URL 而不是 hard-coding 值来执行此操作。您已经在 URL 字符串上调用了 parse_url()，因此您应该已经拥有所需的内容。
像这样的东西应该可以工作：
$server = $url["host"];
$username = $url["user"];
$password = $url["pass"];
$db = substr($url["path"], 1);
$conn = new mysqli($server, $username, $password, $db);
抱歉，我刚刚弄明白为什么它不起作用。我没有部署到主分支。我必须先部署它。
