json - How to get CORS file on S3+CloudFront from WebView -

premise

structure

• json file located s3 cloudfront.
• i try json web site opened @ javafx webview.
• this cloudfront belongs domain web site.

s3

s3 cors setting following.

<?xml version="1.0" encoding="utf-8"?> <corsconfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> <corsrule>     <allowedorigin>*</allowedorigin>     <allowedmethod>get</allowedmethod>     <allowedheader>*</allowedheader> </corsrule> </corsconfiguration> 

cloudfront

behavior target path following.

• forward headers: whitelist
• whitelist headers: origin

problem

i sent request json.

var url = "https://example.com/sample.json"; $.ajax({     datatype: "json",     url: url,     crossdomain: true,     success: function(data) {         console.log("<done>");         console.log("status:" + data.status);     },     error: function(data, textstatus, errorthrown) {         console.log("<error>");         console.log("data.status:" + data.status);         console.log("status:" + textstatus);         console.log("errorthrown:" + errorthrown.message);     }, }); 

when requests sent browser(chrome), can collect response. when requests sent webview(made javafx), error. error logs here.

<error> data.status: 0 status: error errorthrown: undefined 

question

how collect response webview? can edit both client(ajax) , server(cloudfront or s3 setting).

supplemental

i guess reason of error request without origin header. edit request code , try send request orign. error message refused set unsafe header "origin".
