ColdFusion CFC CORS and AJAX posts

问题

I'm trying to get a form posted to a remote server. The general idea, for now, is that the HTML will run locally and will post to a remote server via AJAX.

So there's a form, the JS and the CFC it's posting to.

Below is the JS

$(document).ready(function () {
$("#submit").click(function(){
    var setName = $("input[name='setName']").val();
    var setNumber = $("input[name='setNumber']").val();
    var setTheme = $("input[name='setTheme']").val();

    var retailPrice = $("input[name='retailPrice']").val();
    var purchaseStore = $("input[name='purchaseStore']").val();
    var purchaseDate = $("input[name='purchaseDate']").val();
    var purchasePrice = $("input[name='purchasePrice']").val();

    var condition = $("input[name='condition']").val();

    var sellPrice = $("input[name='sellPrice']").val();
    var sellStore = $("input[name='sellStore']").val();
    var selldate = $("input[name='selldate']").val();

$.ajax({
    type: 'get',
    url: 'http://www.chesteraustin.us/cfc/entry.cfc?ReturnFormat=json',  
    data: {
        method: 'setEntry',
        Set_Name: setName, //CFARGUMENT: JS_VARIABLE
        Set_Number: setNumber,
        Set_Theme: setTheme,
        Retail_Price: retailPrice,
        Purchase_From: purchaseStore,
        Purchase_Price: purchasePrice,
        Purchase_Date: purchaseDate,
        Status: condition,
        Sell_Date: sellPrice,
        Sell_from: sellStore,
        Sell_date: selldate
        },
    contentType: 'json',
    dataType: 'json',
    success: function(response) {
        console.log("you da man");
        }
    });    
}); 
});

Below is the CFC that it is being posted to (I've cut out a lot of it for brevity):

<cfcomponent>
<cfheader name="Access-Control-Allow-Origin" value="*" />
<cfheader name="Access-Control-Allow-Methods" value="GET,PUT,POST,DELETE" />
<cfheader name="Access-Control-Allow-Headers" value="Content-Type" />

<cffunction name="setEntry" access="remote">
    <cfreturn 1>
</cffunction>

</cfcomponent>

EDIT: Cleaned up CFC, removed extraneous comments.

Doing research, I've come across that CFHEADER was supposed to go on top, to allow cross origin, however, Chrome still presents a No 'Access-Control-Allow-Origin' header is present on the requested resource. error.

A couple background things: I'm on a shared host. I have a blank Application.CFC in the folder that the CFC resides in.

So after much research, I've figured out the solution. The ColdFusion code works as intended. However, there was something else controlling the headers (in this case, it was Apache).

Using http://enable-cors.org/server_apache.html as a guide, I modified my .htaccess file in my public_html directory with the following: Header set Access-Control-Allow-Origin "*". Chrome came up with another error, stating that Access-Control-Allow-Headers didn't have Content-Type, so I added that in as well: Header set Access-Control-Allow-Headers Content-Type. Lo and behold, that got it working.

In summary, if CORS on ColdFusion isn't working: <cfheader name="Access-Control-Allow-Origin" value="*" />, check the web server configuration. My .htaccess file now has two lines, and CORS is working now.

Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Headers Content-Type
