将文件上传到WebApi并保存，但可以在IE中使用，但不能在Chrome中使用

Question

尝试将文件上传到Web api并保存，使用IIS在本地运行项目时，可以成功使用Chrome And IE11保存文件。
尝试保存时将项目部署到Test Env时：使用Chrome，我收到“拒绝访问”。使用IE，它可以正常工作。
如何使其与Chrome一起使用？

客户代码：

<?php

require '../../inc/dbinfo.inc';

// Retrieve the POST var:
$num = $_POST['num'];

// Create our blank object:
$obj = new stdClass();

// Combines query 1 and 3:
$sql = $conn->prepare('SELECT COUNT(*) AS sq, SUM(VdrInvoiceAmount) AS itd FROM tblVendorInvoices WHERE VendorPOID1 = ?');
$sql->bind_param('i', $num);
$sql->execute();
$hold = $sql->get_result();
$res = $hold->fetch_object();

$obj->sq = round( $res->sq, 2 );
$obj->itd = round( $res->itd, 2 );

$sql2 = $conn->prepare('SELECT POAmount AS poam FROM tblVendorPOs WHERE VENDORPOID = ?');
$sql2->bind_param('d', $num);
$sql2->execute();
$hold = $sql2->get_result();
$res  = $hold->fetch_object();

$obj->pam = round( $res->poam, 2 );

// May also be handy to output JSON headers:
header('Content-type: application/json');
echo json_encode($obj);
exit();

服务器代码：

            var data = new FormData();

            var files = $("#fileUpload").get(0).files;

            // Add the uploaded image content to the form data collection
            if (files.length > 0) {
                data.append("UploadedImage", files[0]);
            }

            // Make Ajax request with the contentType = false, and procesDate = false
            $.ajax({
                type: "POST",
                url: uriUser + "/UploadFile",
                contentType: false,
                processData: false,
                data: data,
                success: function (data) {
                try {
                    showMsg(MessageType.Info, data);
                    closeWin();
                }
                catch (e) {
                    if (e.message == "") {
                        showMsg(MessageType.Error, msg_error);
                    }
                }
            },
            error: function (response) {

                console.error('DeleteRole failed :' + response);
            }
            });
