d3.js - d3.request generates unauthorized error -

i using d3.request.js download data remote server requires http basic authentication. scripts are:

var query="<request-url>";  d3.request(query)      .post()      .user("login-id")      .password("login-password")      .get(function(error, data) {        //scripts process result        }       )

<script src="https://d3js.org/d3-request.v1.min.js"></script>  <script src="https://d3js.org/d3.v4.min.js"></script>

however upon executing above scripts, received 401 (unauthorized) error. have tested use $.ajax request method before switching d3.request. , working. hence should not cross domain issue remote server. result json object, tested using d3.json failed.

any suggestion problem?

thanks.

is cross-origin request? wag this problem. try this:

var query="<request-url>"; d3.request(query)   .post()   .user("login-id")   .password("login-password")   .on("beforesend", function(request) { request.withcredentials = true; })   .get(function(error, data) {     //scripts process result    }  );
