Good evening, Im just starting to learn curl to exceute xml commands, in a Telco a run this command to validate the login to a network element and then execute other commands:

$ curl -v -X POST http://10.74.13.124:8001 -H "Content-Type: text/xml" -d @test_cnUDM.xml

Output yields Error:

*   Trying 10.74.13.124...

* TCP_NODELAY set

* Connected to 10.74.13.124 (10.74.13.124) port 8001 (#0)

<soapenv:Body>
        <LGI>
                <ADDRESS>10.74.13.124:8001</ADDRESS>

</soapenv:Body>

Hi alexcol,

A 500 error is an issue internal to the server and so should be raised with them, however I suspect that the issue could be malformed xml, your file should read

<soapenv:Envelope xmlns:soapenv=http://schemas.xmlsoap.org/soap/envelope/>
<soapenv:Body>
        <LGI>
                <ADDRESS>10.74.13.124:8001</ADDRESS>
                <OPNAME>USERY</OPNAME>
                <PWD>Whatever</PWD>
                <HLRSN>1</HLRSN>
        </LGI>
</soapenv:Body>

You seem to have missed the opening angle bracket, and their server doesn't seem to catch a parsing failure (possibly worth raising a case with Huawei or their reseller).

BTW, a cute distraction when checking the meaning of http errors is http://http.cat/${ERROR_NUMBER}

RETCODE = 1001 Invalid command <"*  CONTENT-TYPE">
  1. how do i fix this error?
  2. Obviously in the password parameter PWD is exposed, is there any way to pass tge password not to be hardcoded?
  3. I appreciate your help in advanced

This is definitely in the realm of the vendors documentation / customer support, it looks as though it’s interpreting the content-type header as a command rather than a header, but beyond that I cannot say.

Use --netrc or --netrc-file pwfilenam

See man curl
