To access some external services there is a protocol called SOAP. Now ICM can send a SOAP request and get the result back to ICM. Sending request to the SOAP server A SOAP request is a special XML text which contains :
In ICM you can form a SOAP message using the SoapMessage function. It creates a special soapMessage object which holds SOAP method name and it's arguments. Example: # create a message with SOAP method and a namespace req = SoapMessage( "doSpellingSuggestion","urn:GoogleSearch" ) # add method arguments req = SoapMessage( req, "key","btnHoYxQFHKZvePMa/onfB2tXKBJisej" ) # get key from google req = SoapMessage( req, "pharse", "Bretney Spers" ) # some misspelled pharse Once the message is ready it can be send to the server using the read http command. read string s_soapServiceURL + " " + String( soapMessage ) The result of the server response will be stored into s_out variable. It can be parsed to a soapMessage object using the SoapMessage function. Example: HTTP.postContentType = "text/xml" read string "http://api.google.com/search/beta2" + " " + String(req) res = SoapMessage( s_out ) if Error(res) == "" then # process message endif Processing SOAP results To access the content of SOAP message, the Value function is applied If the result of the SOAP response is a simple value, such as integer,`real,`string,`sarray,`rarray,`iarray, then it will be automatically casted to the corresponding ICM type. Otherwise a special type of parray will be returned. In some cases the result returned by SOAP server is actually some complex data structure (not just a single string or number) The most common complex SOAP types are 'struct' and 'array'. Each of them can either contain a simple type of other 'struct' or 'array'. You may navigate through this structure using index expressions: soapObject[ i_integerIndex ] or soapObject[ s_stringIndex ] The number of elements in the array of struct can be returned by Nof function. Sarray of field names of a struct can be returned by Name function
For example the following code navigates through the result obtained from the google search service.
res = Value( SoapMessage( s_out ) ) s_html = "" s_html += "Searched web for <b>" + res["searchQuery"] + "</b>. Search took " + res["searchTime"] + " seconds.<br>" elements = res["resultElements"] for i=1,Nof(elements) resElement = elements[i] s_html += "<br>" cat = String( resElement["directoryCategory"]["fullViewableName"] ) summary = String( resElement["summary"] ) title = String( resElement["title"] ) snippet = String( resElement["snippet"] ) url = String( resElement["URL"] ) cachedSize = String( resElement["cachedSize"] ) if (Length(title) != 0) then s_html += "<font color=\"#0000FF\"><b><u>" + title + "</u></b></font><br>" else s_html += "<font color=\"#0000FF\"><b><u>" + url + "</u></b></font><br>" endif if (Length(snippet) != 0) s_html += snippet + "<br>" if (Length(summary) != 0) s_html += "<font color=\"#808080\">Description:</font> " + summary + "<br>" if (Length(cat) != 0) s_html += "<font color=\"#808080\">Category: <u>" + cat + "</u></font><br>" if (Length(title) != 0) s_html += "<font color=\"#008000\"><u>" + url + "</u> - " + cachedSize + "</font><br>" endfor { KEGG database } KEGG (Kyoto Encyclopedia of Genes and Genomes) is a database resource that integrates genomic, chemical, and systemic functional information. In particular, gene catalogs in the completely sequenced genomes are linked to higher-level systemic functions of the cell, the organism, and the ecosystem. Example of few requests: l_info = l_commands = no HTTP.postContentType = "text/xml" HTTP.soapAction = "SOAP/KEGG" url = "http://soap.genome.jp/keggapi/request_v6.2.cgi" req=SoapMessage( "get_pathways_by_genes" "SOAP/KEGG" ) req=SoapMessage( req "genes_id_list", {"hsa:5292"} ) read string url+" "+String(req) sss = SoapMessage( s_out ) if (Error(sss) == "") then S_path = Value(sss) print "pathways = " Sum(S_path,",") for i=1,Nof(S_path) req=SoapMessage( "get_references_by_pathway" "SOAP/KEGG" ) req=SoapMessage( req "pathway_id", S_path[i] ) read string url+" "+String(req) sss = SoapMessage( s_out ) print "references for " S_path[i] Value(sss) endfor endif For KEGG WSDL file click here.
