Hi! ** Accessing the USGS Web Service Using Python **
I am trying to access the US Geological Survey's gazetteer SOAP web service using Python to find the locations of all the places with the name 'Alexandria.' I tried to keep this simple by putting a soap message in a string and sending the request using httplib. I am receiving the following error message. Reply: 400 Bad Request <h1>Bad Request</h1> ` I apologize in advance if this is not the correct approach. -------------------------- Here is my code ... import httplib # soap string to send soapstr = """<?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> <searchName xmlns="http://gisdata.usgs.net/XMLWebServices/";> <PlaceName>Alexandria</PlaceName> <PlaceType>ppl</PlaceType> <inNumRecords>10</inNumRecords> <inFirstRecord>1</inFirstRecord> </searchName> </soap:Body> </soap:Envelope>""" # send request h = httplib.HTTP('gisdata.usgs.net') h.putrequest("POST", "/XMLWebServices/TNM_Gazetteer_Service.asmx HTTP/1.1") h.putheader("Content-Type", "text/xml; charset=utf-8") h.putheader("Content-Length", str(len(soapstr))) h.putheader ("SOAPAction", "http://gisdata.usgs.net/XMLWebServices/searchName";) h.endheaders() # send soap string h.send(soapstr) # get the HTTP response reply, message, headers = h.getreply() print "Reply: ", reply, message # print the results result = h.getfile().read() print result --------------- Here is the guidance from the USGS Web Site http://gisdata.usgs.net/XMLWebServices/TNM_Gazetteer_Service.asmx?op=searchName The following is a sample SOAP request. The placeholders shown need to be replaced with actual values. POST /XMLWebServices/TNM_Gazetteer_Service.asmx HTTP/1.1 Host: gisdata.usgs.net Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://gisdata.usgs.net/XMLWebServices/searchName"; <?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> <searchName xmlns="http://gisdata.usgs.net/XMLWebServices/";> <PlaceName>string</PlaceName> <PlaceType>string</PlaceType> <inNumRecords>string</inNumRecords> <inFirstRecord>string</inFirstRecord> </searchName> </soap:Body> </soap:Envelope> --------------- Thank you! -- http://mail.python.org/mailman/listinfo/python-list
