在AWS EC2中的何处添加CORS标头 [英] Where to add CORS headers in AWS EC2

问题描述

我正在从浏览器向我的EC2 AWS服务器发出POST请求，但返回以下错误.

I'm making a POST request from a browser to my EC2 AWS server but getting the following error back.

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://www.example.com' is therefore not allowed access. The response had HTTP status code 401.

我已经做了一些研究和发布，我需要在我的EC2 AWS服务器上启用CORS-我了解我应该按照以下内容添加内容

I've done some research and release I need to enable CORS on my EC2 AWS server - I understand that I should be adding something along the lines of

<CORSConfiguration>
    <CORSRule>
    <AllowedOrigin>http://www.example1.com</AllowedOrigin>

    <AllowedMethod>PUT</AllowedMethod>
    <AllowedMethod>POST</AllowedMethod>
    <AllowedMethod>DELETE</AllowedMethod>

   <AllowedHeader>*</AllowedHeader>
 </CORSRule>
 <CORSRule>
     <AllowedOrigin>http://www.example2.com</AllowedOrigin>

     <AllowedMethod>PUT</AllowedMethod>
     <AllowedMethod>POST</AllowedMethod>
     <AllowedMethod>DELETE</AllowedMethod>

     <AllowedHeader>*</AllowedHeader>
 </CORSRule>
 <CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
 </CORSRule>
</CORSConfiguration>

来自AWS文档: AWS EC2 CORS

但是我不确定我实际上还需要在哪里添加它.我的AWS服务器知识有限.

However I'm unsure of where I actually need to add this too. My AWS server knowledge it limited.

这是一个Neo4j db，调用是:

It's a Neo4j db and the call is:

getRequest = function () {
    $.ajax({
        url: 'http://exampleEC2:port/',
        type: 'POST',
        dataType: 'JSON',
        contentType: 'application/json;charset=UTF-8',
        password: 'xxxxxx',
        username: 'xxxx',
        data: dataObject,
        success: function (data) {
            console.log("success");
        },
        error: function(error) {
            console.log(error);
        }
    });
};

推荐答案

我花了数小时与之搏斗.尝试.htaccess.尝试.conf.到处都是防火墙.

I spent hours wrestling with this. Tried .htaccess. Tried .conf. Fooling around with firewalls.

最后，它是一行php:

In the end it was a single line of php:

header('Access-Control-Allow-Origin: *');
