尝试在页面上发送表单时收到此错误。当我在电子邮件输入字段中输入某些电子邮件地址（例如“我的名字”和@ gmail.com）时，发送邮件有效，但是当输入“假名”和@ gmail.com（gmail只是一个例子，我用gmx也得到相同的结果。）
我正在将swiftmailer与jquery验证程序一起使用。
因此它有时可以工作，而在其他情况下则无法工作。我试图缩小范围，这似乎与我在输入字段中输入的电子邮件地址有关，这让我感到非常困惑。
Ajax代码段：
$.ajax({
url: 'mailer.php',
method: 'post',
data: formSerialized,
dataType: 'text', // the type of data that you are expecting back from the server (text = no pre-processing occurs)
error: function (jqXHR, textStatus, errorThrown) { // errorObject, errorText, errorHTTP
// ajax request failed
console.log(textStatus);
console.log(errorThrown);
ga('send', 'event', 'Kontaktformular', 'Ajax fehlgeschlagen');
$('#contact-form .spinner').hide();
$('#contact-form').hide();
showFormFeedbackError(undefined, 'Ajax Error: ' + errorThrown);
},
success: function (responseData, textStatus, jqXHR) {
// ajax request succeeded
console.log(textStatus);
console.log(responseData);
$('#contact-form .spinner').hide();
$('#contact-form').hide();
// responseData is formatted according to the dataType parameter
if ($.isNumeric(responseData)) {
switch (parseInt(responseData)) {
case 1: // success
ga('send', 'event', 'Kontaktformular', 'Kontaktformular abgeschickt');
showFormFeedbackSuccess();
break;
default:
break;
}
} else {
ga('send', 'event', 'Kontaktformular', 'Kontaktformular fehlgeschlagen');
showFormFeedbackError(undefined, 'Mailer Error: ' + responseData);
}
},
complete: function (jqXHR, textStatus) {
// ajax request finished, whether in failure or success
// called after success and error callbacks are executed
resetForm();
$('html, body').animate({
scrollTop: $('#contact-form').siblings('.feedback').offset().top
}, 1000);
