Debugging jQuery ajax 500 Internal server error
提问by Himanshu Yadav
My working CodeIgniter site is giving a 500 Internal Server Error while hosting it on MediaTemple. It is happening during a jQuery Ajax call.
我的工作 CodeIgniter 站点在 MediaTemple 上托管时出现 500 内部服务器错误。它发生在 jQuery Ajax 调用期间。
I have no idea what could have gone wrong. Is the error from the controller or the model? My Ajax call:
我不知道出了什么问题。是控制器的错误还是模型的错误？我的 Ajax 调用：
$.ajax({
url: "<?php echo site_url('invites/save_email') ?>",
type: 'POST',
data: form_data,
success: function(msg) {
window.location.href = "<?php echo site_url('invites/moreinvites')?>"
return true;
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(thrownError);
alert(xhr.responseText);
}
});
xhr.responseText has returned me <p>The action you have requested is not allowed.</p>. But what does that mean?
xhr.responseText 已返回给我<p>The action you have requested is not allowed.</p>。但是，这是什么意思？

You can try using alert(xhr.responseText);or console.log(xhr.responseText);(the later will show up in your browser console e.g. firebug) in your error callback, doing so you can get the message associated with the exception (if any).
您可以尝试在错误回调中使用alert(xhr.responseText);or console.log(xhr.responseText);（后者将显示在您的浏览器控制台中，例如 firebug），这样做您可以获得与异常相关的消息（如果有）。
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(xhr.responseText);
alert(thrownError);
}
or
或者
error: function (xhr, ajaxOptions, thrownError) {
console.log(xhr.status);
console.log(xhr.responseText);
console.log(thrownError);
}

You need to configure the webconfig file to receive POST request.
您需要配置 webconfig 文件以接收 POST 请求。
<system.web>
<webServices>
<protocols>
<add name="HttpPost" />
</protocols>
</webServices>
</system.web>
