如何从当前打开的 HTML 网站中的元素获取数据？

Status code: {response.status_code}") 这里我们向站点发送一个 HTTP 请求，如果响应是 200（等于 ok ），我们将响应中的 HTML 数据发送到变量并使用 Beatiful Soup 解析它。您需要将解析代码更改为最适合您的代码，但此时您可以询问 Chat-GPT。

表单响应：“无法处理请求 HTTP ERROR 500”。我做错了什么？

我尝试在网站上编写 php 表单，但收到错误 500。我无法弄清楚我做错了什么。你能看一下代码看看我做错了什么吗？ PHP：我尝试在网站上编写 php 表单，但收到错误 500。我无法弄清楚我做错了什么。你能看一下代码看看我做错了什么吗？ PHP： <?php // define variables and set to empty values $name = $email = $phone = $enquiry = ""; if ( $_SERVER[ "REQUEST_METHOD" ] == "POST" ) { if ( empty( $_POST[ "name" ] ) ) { $nameErr = "Name is required"; } else { $name = test_input( $_POST[ "name" ] ); // check if name only contains letters and whitespace if ( !preg_match( "/^[a-zA-Z-' ]*$/", $name ) ) { $nameErr = "Only letters and white space allowed"; } } if ( empty( $_POST[ "email" ] ) ) { $emailErr = "Email is required"; } else { $email = test_input( $_POST[ "email" ] ); // check if e-mail address is well-formed if ( !filter_var( $email, FILTER_VALIDATE_EMAIL ) ) { $emailErr = "Invalid email format"; } } if ( empty( $_POST[ "phone" ] ) ) { $comment = ""; } else { $comment = test_input( $_POST[ "phone" ] ); } if ( empty( $_POST[ "enquiry" ] ) ) { $comment = ""; } else { $comment = test_input( $_POST[ "enquiry" ] ); } } // Create the email and send the message $destination = "[email protected]"; $subject = "Website Contact Form Enquiry: $name"; $body = "You have received a new message from your website contact form.\\n\\n"."Here are the details:\\n\\nName: $name\\n\\nEmail: $email\\n\\nPhone: $phone\\n\\nEnquiry:\\n$enquiry"; $header = "From: [email protected]\\n"; $headers = array(); $headers[] = "MIME-Version: 1.0"; $headers[] = "Content-type: text/plain; charset=iso-8859-1"; $headers[] = "From: " . $fromAddress; $headers[] = "Subject: " . $subject; $headers[] = "X-Mailer: PHP/".phpversion(); mail($destination, $subject, $message, implode("\r\n", $headers)); // mail($to,$subject,$msg,$headers); echo "Email successfully sent."; ?> HTML 格式： <form id="contact-form" method="post" action="/contact.php" role="form"> <div class="messages"></div> <div class="controls"> <div class="row"> <div class="col-md-10"> <div class="form-group"> <input id="form_name" type="text" name="name" class="form-control" placeholder="Name*" required="required" data-error="Your name is required." > <div class="help-block with-errors"></div> </div> </div> <div class="col-md-10"> <div class="form-group"> <input id="form_email" type="email" name="email" class="form-control" placeholder="Email*" required="required" data-error="Valid email is required." > <div class="help-block with-errors"></div> </div> </div> <div class="col-md-10"> <div class="form-group"> <input id="form_phone" type="text" name="phone" class="form-control" placeholder="Phone" > <div class="help-block with-errors"></div> </div> </div> </div> <div class="row"> <div class="col-md-10"> <div class="form-group"> <textarea id="form_enquiry" name="enquiry" class="form-control" placeholder="Enquiry*" rows="6" required="required" data-error="Please, leave us a message."></textarea> <div class="help-block with-errors"></div> </div> </div> <div class="col-md-12"> <input class="btn btn-large btn-primary centre mt-10" type="submit" value="Submit" > </div> </div> </div> </form> 我已按照其他人的指示使表单正常工作，但所做的更改仍然会出现错误。这是一个简单的形式，但我似乎对我做错了什么缺乏了解。请帮助我。如果您查看发送邮件的行，这是一个硬行结尾，将 $headers 推到新行上吗？这将调用 500 错误。查看 /var/log/apache2/error.log（如果您使用的是 Debian）或 /var/log/httpd/error.log（如果使用的是 RHEL 或类似系统）。您的代码存在许多问题，但首先关注快乐的道路，然后让事情正常运行。
