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 - ----
# (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:stringAzithromycin/ns:query
ns:token xmlns:ns=http://www.chemspider.com/;
xsi:type=xsd:string----/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/;
querystring/query
tokenstring/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,

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
