In NetSuite with SuiteScript 2.0 unable to send a

问题:

I am not able to send my "multipart/form-data' file to this API. If I use POSTMAN it's working but with the https post method it seems that netsuite doesn't recognize the "form-data" content-type. Somebody knows how to send a form-data with SuiteScript 2 ? Here is a part of my code:

var fileObj = file.create({
                name: invoiceNumber + '_ubl.xml',
                fileType: file.Type.XMLDOC,
                contents: einvoicecontentwithpdf,
                folder : 120,
                isOnline : false
            });

var headers = {
                    'Authorization': 'Basic xxxxxxxxxxxxxxxxxxxxx',
                    'Content-Type':  'multipart/form-data'
            };

            var response = https.post({
                url: 'https://community-api-uat-1-2.nxt.uat.unifiedpost.com/api/universal_connector/v1/uc/ar',
                body: {
                    'file': fileObj                    
                },
                headers: headers 
            });

You have to build the whole body yourself.

This works as much as I've tested so far. Code may look a little non-idomatic because it's compiled from Typescript.

Note that to include non-text files this would have to be adapted to base64 encode the file bodies.

a simple test:

 */
define(["require", "exports", "N/file", "./multiPartUpload"], function (require, exports, file, multiPartUpload_1) {
    Object.defineProperty(exports, "__esModule", { value: true });

        var files = [
            { name: 'f1', value: file.load({ id: 1056 }) }, // file cabinet ids; you can use dynamic files
            { name:'t1', value:'test'},
            { name: 'f2', value: file.load({ id: 7479 }) }
        ];
        var resp = multiPartUpload_1.uploadParts('https://your-test-server/', {}, files);
        context.response.write({ output: resp.body });
    }
    exports.onRequest = onRequest;
});
