我创建了一个网页，在表单中插入有效的电子邮件地址后，使用Javascript和PHP发送电子邮件。
表单对插入的邮件执行验证，如果出现错误或发送失败，则会显示弹出窗口。它工作正常。
如果一切顺利，但没有发生，应该显示一个绿色弹出窗口。邮件已发送，我看到以下错误（如果我使用#button-send表单）：
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
这是代码：

编辑：我已经在php文件中添加了error_reporting(E_ALL);，并且看到有一些变量没有初始化。特别是CCD_ 3 $ip_pool CCD_。我添加了以下内容：
$async = false;
$ip_pool = null;
$send_at = null;
之前
$result = $mandrill->messages->send($message, $async, $ip_pool, $send_at);
但一切都没有改变。查看我的提供者的php错误日志，php上没有出现新的错误。
我还注意到第一次发送对$mandrill->messages->send($message, $async, $ip_pool, $send_at);没有用处。只需要第二个。我删除了第一个，但没有任何变化。
正确的代码：
<?php
error_reporting(E_ALL);
require 'mandrill.php';
$send_email_to = "contacts@docgem.it";
$email_subject = "Feedback landing page DocGem";
function send_email($email)

global $send_email_to;
global $email_subject;
$headers = "MIME-Version: 1.0" . "rn";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "rn";
$headers .= "From: ".$email. "rn";
$message = "<strong>Email = </strong>".$email."<br>";
try{
$mandrill = new Mandrill("mfSC_K7XBO8Kj5nW0VobjQ");
$template_name = 'docgem autoresponder';
$template_content = array(
array(
'name' => 'example name',
'content' => 'example content'
)
);
$message = array(
'html' => '<p>this is a test message with Mandrills PHP wrapper!</p>',
'subject' => 'Feedback landing page DocGem',
'from_email' => 'contacts@docgem.it',
'to' => array(
array(
'email' => $email,
'name' => 'Recipient 1'
)
),
'merge_vars' => array(
array(
'rcpt' => $email,
'vars' => array(
array(
'name' => 'merge2',
'content' => 'merge2 content'
)
)
)
)
);
json_encode($mandrill->messages->sendTemplate($template_name, $template_content, $message));
return true;
}
catch(Mandrill_Error $e) {
// Mandrill errors are thrown as exceptions
echo 'A mandrill error occurred: ' . get_class($e) . ' - ' . $e->getMessage();
// A mandrill error occurred: Mandrill_Unknown_Subaccount - No subaccount exists with the id 'customer-123'
throw $e;
}
}
function validate($email)
{
$return_array = array();
$return_array['success'] = '1';
$return_array['email_msg'] = '';
if($email == '')
{
$return_array['success'] = '0';
$return_array['email_msg'] = 'inserire email';
}
else
{
$email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email)) {
$return_array['success'] = '0';
$return_array['email_msg'] = 'inserire email valida';
}

return $return_array;
}
$email = $_POST['email'];
$return_array = validate($email);
if($return_array['success'] == '1')
{
send_email($email);
}
header('Content-type: text/json');
echo json_encode($return_array);
?>
在JSON相关的输出中，特别是当它将被javascript读取时，您需要使用错误报告功能，并删除die（）；在echo json_encode之后。。。
<?php
error_reporting(0);
...
...
...
header('Content-Type:application/json;');
echo json_encode($return_array);
