How to add file attachment to soap request with node-soap library ? - node.js

Question

I need to add an file attachment to a soap request from node.js application.
I am able to send request with node-soap library, and now I need to add a file to the request.
I did it with a java client or with soapUI, but I have to do it in node.js, maybe it's possible to do that overriding default request object ?

Answer 1

I didn't find a solution with node-soap, I had to build manually my soap request :
var soapHeader = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Header/><soapenv:Body><ws:method>';
var soapFooter = '</ws:method></soapenv:Body></soapenv:Envelope>';
function sendSoapRequestWithAttachments(soap,files){
var soapRequest = jsonToXml.buildObject(mail);
var finalSoapRequest = soapHeader + soapRequest + soapFooter;
var multipartMail = [];
// Add soap request
multipartMail.push({
'Content-Type': 'text/xml; charset=utf-8',
body: finalSoapRequest
});
// Add attachments
if (files) {
files.forEach(function (file) {
multipartMail.push({
'Content-Id': '<' + file.uuid + '>',
'Content-Type': 'application/octet-stream',
'Content-Transfer-Encoding': 'binary',
body: fs.createReadStream(file.path)
});
});
}
var options = {
uri: URL,
method: 'POST',
multipart: multipartMail
};
request.post(options, function (error, response) {
...
}
}

I found a way to send attachment using node-soap using base64 encoding
here is an example
import soap from 'soap'
import fs from 'fs'
async function main(){
const filepath = '/path/to/attachment/file.extension'
const client = await soap.createClientAsync(/* ... */)
const result = await client.AnApiMethodAsync({
expectedKeyForTheFile: await fs.readFileAsync(filepath, 'base64')
})
}
main()
