[R] SSOAP and Chemspider: Security token?

Dear community,

has anyone managed to get SSOAP working with the ChemSpider Web APIs, using
functions which need the security token?
I use SSOAP 0.9-0 from the OmegaHat repository.
In the example code from SSOAP there is a sample which uses a token function.
Interestingly, it checks if(!is.character(token)) first (and proceeds if the
token is NOT character.) I can't test that function since I have no idea how
to get the token into "non-character" form :)

My code:

library(SSOAP)
chemspider_sectoken <- "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
# (token was here)
cs <- processWSDL("http://www.chemspider.com/Search.asmx?WSDL")
# intf <- genSOAPClientInterface(,cs)
# (this fails, see below. The Mass Spec API is correctly parsed. Therefore by
hand:)

csidlist <- .SOAP(server=cs@server,
                  method="SimpleSearch",
                  .soapArgs=list(
                    query="Azithromycin",
                    token=token
                  ),
                  action=I("http://www.chemspider.com/SimpleSearch"),
                  xmlns=c("http://www.chemspider.com/")
                  )

Fehler: Error occurred in the HTTP request:  Unauthorized web service usage.
Please request access to this service. ---> Unauthorized web service usage.
Please request access to this service.

If one looks into the request, the doc seems to be correct:

<?xml version="1.0"?>

<SOAP-ENV:Envelope
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

  <SOAP-ENV:Body>

    <ns:SimpleSearch xmlns:ns="http://www.chemspider.com/">

      <ns:query xmlns:ns="http://www.chemspider.com/"
xsi:type="xsd:string">Azithromycin</ns:query>

      <ns:token xmlns:ns="http://www.chemspider.com/"
xsi:type="xsd:string">xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx</ns:token>

    </ns:SimpleSearch>

  </SOAP-ENV:Body>

</SOAP-ENV:Envelope>



Compared to the sample request from the ChemSpider homepage:

<?xml version="1.0" encoding="utf-8"?>

<soap:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

  <soap:Body>

    <SimpleSearch xmlns="http://www.chemspider.com/">

      <query>string</query>

      <token>string</token>

    </SimpleSearch>

  </soap:Body>

</soap:Envelope>



To me, both look like perfectly fine XML and should be identical to the
ChemSpider XML parser. Do I need to write the token in another format? Is
something else wrong? I also tried to use .literal = T to no avail: "Error
occurred in the HTTP request:  Empty query"

Best regards,
-Michael

PS: the error message from the genSOAPClientInterface call is:
Note: Method with signature "ClassDefinition#list" chosen for function
"resolve",
target signature "ExtendedClassDefinition#SchemaCollection".
"SOAPType#SchemaCollection" would also be valid
Fehler in makePrototypeFromClassDef(properties, ClassDef, immediate, where) :

Zusätzlich: Warnmeldung:

[R] SSOAP and Chemspider: Security token?

Hi Michael

Thanks for the report and digging into the actual XML documents
that are sent.

It turns out that if I remove the redundant namespace definitions
and just use a single one on the <SimpleSearch> node, all is apparently
fine.

I've put a pre-release version of the SSOAP package that does at

  http://www.omegahat.org/Prerelease/SSOAP_0.9-1.tar.gz

You can try that.

I'll release this version when I also fix the issue with
XMLSchema  that causes the error in genSOAPClientInterface()


BTW, the if(!is.character(token)) in the example in chemSpider.R
is an error - a mixture of !is.null() and then checking only if it
is a character.


  Best,
    Duncan

[R] SSOAP and Chemspider: Security token?

Dear Duncan, 

thanks for the quick answer. However, I already sorted one error out - turned
out that I was just stupid: The security token worked fine once I filled all the
additional "required information" on the ChemSpider profile (which
means the token showing up on your profile is non-functional as long as that
information isn't complete - ChemSpider doesn't tell you that, or force
you to fill in the information, however.)

Best,
-Michael
