I have a RFID reader, which I can call by a HTTP request on address for example:

[http://192.168.1.15/status.xml](http://192.168.1.15/status.xml)

There is a basic authentication, when I run the address above in chrome browser and then I get a response:

```auto
<status>
<netbios>NANO RFID </netbios>
<mac>E8EB1B487A52</mac>
<id>1E009BF6CA</id>
<newId>0</newId>
<cnt>1</cnt>
<resetFlag>1</resetFlag>
<enable>1</enable>
<httpClientStatus>0</httpClientStatus>
<out>0</out>
<in>1</in>
<model>RFID NANO</model>
<fw>0.46</fw>
<hw>1.0</hw>
</status>

```

When I have tried the http request node, i get this error : RequestError: Parse Error: Invalid header token : [http://192.168.1.15/status.xml](http://192.168.1.15/status.xml)

When I have checked the headers of the status.xml page, i can see this:

This is configuration of the node:

The question is - how to get the http request node working? Thanks for help!

What version of Node-RED and node JS are you running? Disable strict didn't work properly prior to node-red v3.1.0

Also, try to show us the raw response from the request - I suspect the device is responding with poorly formatted headers (chrome is more forgiving)

Hello, i am running node red v.3.1.0 and Node JS version 20.9.0.

The response headers I see in chrome is :  
HTTP/1.1 200 OK  
Connection: close  
Content-Type: text/xml  
Access-Control-Allow-Origin: \*  
Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"

Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token"

Your raw post:

Several of them headers are invalid (no `:` colon) - you should see if the device has a firmware update (or report it to the device maintainers)

That's why Chrome is only showing 4 parsed headers in the image.

This may be an upstream issue with `got` library or may be Node-RED needs to tell got to ignore invalid headers.

Unfortunately I am away from computers for the next week so can't help further at this point. Hopefully someone else on the forum can help further until I am able to look deeper into the issue.

If this is blocking you and you cannot wait, then you might want to try running cURL via the exec node or importing `fetch` in a function node.

I was trying to use exec node, i set it up like this:

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/e/9/e9668125e948dcd2e8518e0c184e290e63265e3d.png)

I run this command: curl [http://192.168.1.15/status.xml](http://192.168.1.15/status.xml) -u "admin:admin00"

But the exec node is returning error 8... When i try to run the command in command line in windows, i got:  
curl: (8) Header without colon

That backs up my previous statement!

Have you looked for updated firmware? Contacted the device manufacturer?

That would seem to confirm what @Steve-Mcl said - the server is sending an invalid set of headers without : in. Curl error 8 is also "weird reply from server" so yes... need you to fix the server.

yeah I mean the http standard has only been around since 1999 - not like people haven't had a chance to read it yet... 😉

I think, that developers in China have their own opinion on this standard :). I got new FW for the reader, so I am going to test it now...

So the uppdate of FW helped. Now, the http server is returing good headers and both solution - using http request node and using curl is working OK. Thanks for help.
