Question

我正在制作一个订阅时事通讯的表格，为此我使用ajax请求来调用mailchimp api。 api单独工作，我测试过它。但是在ajax代码中，我在发送和完成部分之前发出警告它是正确的，但是在成功时它什么也没做。

这是我的代码：

HTML表单代码

<form id="mc-embedded-subscribe-form" name="mc-embedded-subscribe-form" class="validate">
    <input type="email" value="" name="EMAIL" class="email" id="useremail" placeholder="Type our mail address" required>
    <input type="button" value="subscribe" name="subscribe" id="mc-embedded-subscribe" class="mc-button" >
      <div id="subscribe-result">
      </div>
</form>

脚本代码

<script>
$("#mc-embedded-subscribe").click(function() { 

var email = $('#useremail').val();

$.ajax({
    type: 'post',
    url: "newslatter.php", 
    dataType: 'json',
    data: 'useremail='+email,
    beforeSend: function() {
    },
    complete: function() {
    },  
    success: function(data)
    {
        alert("enter success");
        if(data.type == 'error')
        {
            output = "<a color='red'>"+data.text+"</div>";
        }else{
            output = data.text;
        }
        $("#subscribe-result").html(output);
    }
});
});
</script>

这里是 NewsLatter的PHP代码

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST') {

//check if its an ajax request, exit if not
if (!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {

    //exit script outputting json data
    $output = json_encode(
            array(
                'type' => 'error',
                'text' => 'Request must come from Ajax'
    ));

    die($output);
}

//check $_POST vars are set, exit if any missing
if ( !isset($_POST["useremail"]) ) {
    $output = json_encode(array('type' => 'error', 'text' => 'Input fields are empty!'));
    die($output);
}

//Sanitize input data using PHP filter_var().
$useremail = filter_var(trim($_POST["useremail"]), FILTER_SANITIZE_EMAIL);

//additional php validation

if (!filter_var($useremail, FILTER_VALIDATE_EMAIL)) { //email validation
    $output = json_encode(array('type' => 'error', 'text' => 'Please enter a valid email!'));
    die($output);
}
$list_id = '***secret***';
$api_key = '***secret***';


$data_center = substr($api_key,strpos($api_key,'-')+1);

$url = 'https://'. $data_center .'.api.mailchimp.com/3.0/lists/'. $list_id .'/members';

$json = json_encode([
    'email_address' => $email,
    'status'        => 'subscribed', //pass 'subscribed' or 'pending'
]);


$ch = curl_init($url);
curl_setopt($ch, CURLOPT_USERPWD, 'user:' . $api_key);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
$result = curl_exec($ch);
$status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);


if ($status_code!=200) {
    $output = json_encode(array('type' => 'error', 'text' => 'Something Went Wrong'));
    die($output);
} else {
    $output = json_encode(array('type' => 'message', 'text' => 'Hi ' . $username . ' Thank you for your email'));
    die($output);
}

Answer 1

添加

header('Content-Type: application/json');

在发送json响应之前在php中

也是一个大括号＆＃34;}＆＃34;需要在文件和文件中关闭块

if ($_SERVER['REQUEST_METHOD'] == 'POST') {

Answer 2

此行存在问题

$json = json_encode([
    'email_address' => $email,
    'status'        => 'subscribed', //pass 'subscribed' or 'pending'
]);

变量名称为 $ useremail ，而非$ email，因此请将其更改为

 $json = json_encode([
        'email_address' => $useremail,
        'status'        => 'subscribed', //pass 'subscribed' or 'pending'
    ]);

新闻代码：

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    //check if its an ajax request, exit if not
    if (!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {
        //exit script outputting json data
        $output = json_encode(
            array(
                'type' => 'error',
                'text' => 'Request must come from Ajax'
            ));
        die($output);
    }
    //check $_POST vars are set, exit if any missing
    if ( !isset($_POST["useremail"]) ) {
        $output = json_encode(array('type' => 'error', 'text' => 'Input fields are empty!'));
        die($output);
    }
    //Sanitize input data using PHP filter_var().
    $useremail = filter_var(trim($_POST["useremail"]), FILTER_SANITIZE_EMAIL);
    //additional php validation
    if (!filter_var($useremail, FILTER_VALIDATE_EMAIL)) { //email validation
        $output = json_encode(array('type' => 'error', 'text' => 'Please enter a valid email!'));
        die($output);
    }
    $list_id = '***secret***';
    $api_key = '***secret***';
    $data_center = substr($api_key,strpos($api_key,'-')+1);
    $url = 'https://'. $data_center .'.api.mailchimp.com/3.0/lists/'. $list_id .'/members';
    $json = json_encode([
        'email_address' => $useremail,
        'status'        => 'subscribed', //pass 'subscribed' or 'pending'
    ]);
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_USERPWD, 'user:' . $api_key);
    curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
    $result = curl_exec($ch);
    $status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
    if ($status_code!=200) {
        $output = json_encode(array('type' => 'error', 'text' => 'Something Went Wrong'));
        die($output);
    } else {
        $output = json_encode(array('type' => 'message', 'text' => 'Hi ' . $username . ' Thank you for your email'));
        die($output);
    }
}
