发送 NodeJS ExpressJS 响应 HTTP 状态码 200 + 有效载荷

Question

I need to send back an acknowledge response back with the following characteristics:

• HTTP Status code 200
• payload (body?)

My try:

 function handleMessage(req, res){ let otaRequestBuffer = []; req.on('readable', () => { let data; while (data = req.read()) { otaRequestBuffer.push(data.toString()); } }); req.on('end', () => { let otaRequest = otaRequestBuffer.join(''); try { let parser = new DOMParser(); let xmlDoc = parser.parseFromString(otaRequest, "text/xml"); let soapHeader = parseSoapHeader(xmlDoc); const soapAction = req.headers['soapaction'].toString(); const ack = `<?xml version='1.0' encoding='utf-8'?> <env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope"> <env:Header> <htnga:CorrelationID xmlns:htnga="http://htng.org/PWSWG/2007/02/AsyncHeaders">${soapHeader.correlationId}</htnga:CorrelationID> <htnga:RelatesToCorrelationID xmlns:htnga="http://htng.org/PWSWG/2007/02/AsyncHeaders">${soapHeader.correlationId}</htnga:RelatesToCorrelationID> </env:Header> <env:Body> <ns:HTNG_AcknowledgeReceipt xmlns:ns="http://htng.org/2014B"/> </env:Body> </env:Envelope>` res.sendStatus(200); res.write(ack); } catch (error) { console.log(error); } });

But this only sends OK. How can I send also the payload/body and the HTTPS status code 200.

Thanks for the help.

Here a screenshot from the docs from the API provider:

By default the status code is 200 for res.send(), but for other status codes, you can do that using

res.status(403).send("You are not authorised to view this")
