passing parameters to a web service in soap request from Web.network.Create Request

• Hooper

  I have found my mistake:

  was:

  strPostArgs.append("<GetSpaceStat xmlns=\"http://tempuri.org\">");

  necessary:

  strPostArgs.append("<GetSpaceStat xmlns=\"http://tempuri.org/\">");

  Hi mmsignh,

  I'm still having the problem, I created a simple web service at:

  http://margell.net/casey/service.asmx

  That has a single Hello operation. Feel free to play with this service a bit. For a given name it returns "Hello NAME!".

  I'm having the same problem as before where I don't ever see my output after the execute statement and the callback never gets called. Here is the exact code I'm running right now:

  var url = "http://margell.net/casey/service.asmx";
  var aObjHeaders = new Array();
  aObjHeaders["SOAPAction"] = "CaseyM.Service/Hello";
  aObjHeaders["Content-Type"] = "text/xml";
  
  var strPostArgs = new Web.StringBuilder();
  strPostArgs.append("< xml version=\"1.0\" encoding=\"utf-8\" >");
  strPostArgs.append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" ");
  strPostArgs.append("xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlnsoap=\"http://schemas.xmlsoap.org/soap/envelope/\">");
  strPostArgs.append("<soap:Body>");
  strPostArgs.append("<Hello xmlns=\"CaseyM.Service\">");
  strPostArgs.append("<name");
  strPostArgs.append("Casey");
  strPostArgs.append("</name>");
  strPostArgs.append("</Hello>");
  strPostArgs.append("</soap:Body>");
  strPostArgs.append("</soap:Envelope>");
  

  var r = Web.Network.createRequest( Web.Network.Type.XMLPost, // Network type
  url, // URL of web service
  null, // Object passed to callback
  serviceCallback, // Callback function
  Web.Utility.Prioritizer.Priorities.Medium, // Priority
  strPostArgs.toString(), // HTTP Post string
  aObjHeaders ); // Array of headers

  alert("finished building string, calling execute");
  r.execute();
  alert("leaving getImageFilename");
  }
  
  function serviceCallback(response) {
  alert("in serviceCallback, response: \n" + response);

  }

  EDITED:

  Here is the code for the service:

  <%@ WebService Language="C#" Class="Service" %>

  using System;
  using System.Web;
  using System.Web.Services;
  using System.Web.Services.Protocols;

  
  [WebService(Namespace="CaseyM.Service",
  Description="<b>A simple test web service.</b>")]

  public class Service : System.Web.Services.WebService
  {
  public Service() { }

  [WebMethod]
  public string Hello(string name) {
  
  return "Hello " + name + "!";
  }
  }

  I found my problem as well. The issue was that IE was blocking cross domain calls. Argh.

  The parameters are not getting passed because XMLPost doesn't work. Web.Network.createRequest uses a proxy system to allow cross-domain calls that would otherwise be blocked by the Same Origin Policy. Unfortunately, last I checked that proxy does not like XMLPost. It seems that things may have changed somewhat, as it used to be that XMLPost just wouldn't go through the proxy at all and you'd end up with an Access Denied error. Now it looks like it's going through, but stripping off all of the POST data, making the type just as useless for a different reason.

  It's been a while since I tried XMLPost. I may have to try it again to see if it may actually work now.

  seems, your problem in

  strPostArgs.append("id.toString");

  necessary

  strPostArgs.append(id.toString);

  but I have same problem - not passing parameter

  var m_spacesName = "http://live.com";

  var aObjHeaders = new Array();

  aObjHeaders["SOAPAction"] = "http://tempuri.org/SpaceStat";

  aObjHeaders["Content-Type"] = "text/xml";

  var strPostArgs = new Web.StringBuilder();

  strPostArgs.append("< xml version=\"1.0\" encoding=\"utf-8\" >");

  strPostArgs.append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" ");

  strPostArgs.append("xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlnsoap=\"http://schemas.xmlsoap.org/soap/envelope/\">");

  strPostArgs.append("<soap:Body>");

  strPostArgs.append("<SpaceStat xmlns=\"http://tempuri.org\">");

  strPostArgs.append("<host>");

  strPostArgs.append(m_spacesName);

  strPostArgs.append("</host>");

  strPostArgs.append("</SpaceStat>");

  strPostArgs.append("</soap:Body>");

  strPostArgs.append("</soap:Envelope>");

  var r = Web.Network.createRequest( Web.Network.Type.XMLPost, // Network type

  url, // URL of web service

  null, // Object passed to callback

  CallbackFn, // Callback function

  Web.Utility.Prioritizer.Priorities.Medium, // Priority

  strPostArgs.toString(), // HTTP Post string

  aObjHeaders ); // Array of headers

  r.execute();

  passing null instead of m_spacesName value. Why

  Hi Casey,

  There seem to be some config errors on your server as when i try to access the .asmx file, i get an error :

  Server Error in '/' Application.

  Hi mmsignh,

  Would it be possible for you to post the code that you got to work when consuming a web service

  I've based my code on the example from the SDK (http://microsoftgadgets.com/livesdk/docs/ApiRef.Web.Network.htm) but when I execute the request I'm not getting any error but at the same time I'm not getting the alert after calling execute or the alert in the callback. Here's a snippet from my code, I've bolded the areas that I changed for anonymity's sake:

  
  function getImageFilename() {
  alert("entering getImageFilename");
  var aObjHeaders = new Array();
  aObjHeaders["SOAPAction"] = "namespace.Service/GetFilename";
  aObjHeaders["Content-Type"] = "text/xml; charset=utf-8";
  //aObjHeaders["Host"] = "domain";
  
  alert("getImageFilename: 1")
  var strPostArgs = new Web.StringBuilder();
  alert("getImageFilename: 2")
  strPostArgs.append("< xml version=\"1.0\" encoding=\"utf-8\" >");
  strPostArgs.append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" ");
  strPostArgs.append("xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlnsoap=\"http://schemas.xmlsoap.org/soap/envelope/\">");
  strPostArgs.append("<soap:Body>");
  strPostArgs.append("<GetFilename xmlns=\"domain\">");
  strPostArgs.append("<email>");
  strPostArgs.append(m_savedPreferences[EMAIL]);
  strPostArgs.append("</email>");
  strPostArgs.append("</GetFilename>");
  strPostArgs.append("</soap:Body>");
  strPostArgs.append("</soap:Envelope>");
  alert("getImageFilename: 3")
  var r = Web.Network.createRequest(Web.Network.Type.XMLPost, // Network type
  WEBSERVICEURL, // URL of web service
  null, // Object passed to callback
  serviceCallback, // Callback function
  Web.Utility.Prioritizer.Priorities.Medium, // Priority
  strPostArgs.toString(), // HTTP Post string
  aObjHeaders ); // Array of headers
  alert("finished building string, calling execute");
  r.execute();
  alert("leaving getImageFilename");
  }
  
  function serviceCallback(response) {
  alert("in serviceCallback, response: \n" + response);

  }

  Any input anyone has is greatly appreciated.

  Casey

  Hi Casey

  Pasted below is the code that worked perfectly fine for me.

  var url = http://{URL TO SERVICE.asmx file};

  var aObjHeaders = new Array();

  aObjHeaders["SOAPAction"] = "{SERVICE NAME}/{METHOD NAME}";

  aObjHeaders["Content-Type"] = "text/xml";

  var strPostArgs = new Web.StringBuilder();

  strPostArgs.append("< xml version=\"1.0\" encoding=\"utf-8\" >");

  strPostArgs.append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" ");

  strPostArgs.append("xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlnsoap=\"http://schemas.xmlsoap.org/soap/envelope/\">");

  strPostArgs.append("<soap:Body>");

  strPostArgs.append("<{METHOD NAME} xmlns=\"{SERVICE NAME}\">");

  strPostArgs.append("<{PARAMETER NAME}>");

  strPostArgs.append({VALUE OF PARAMETER});

  strPostArgs.append("</{PARAMETER NAME}>");

  strPostArgs.append("</{METHOD NAME}>");

  strPostArgs.append("</soap:Body>");

  strPostArgs.append("</soap:Envelope>");

  var r = Web.Network.createRequest( Web.Network.Type.XMLPost, // Network type

  url, // URL of web service

  null, // Object passed to callback

  OnFeedReceived, // Callback function

  Web.Utility.Prioritizer.Priorities.Medium, // Priority

  strPostArgs.toString(), // HTTP Post string

  aObjHeaders ); // Array of headers

  r.execute();

  Just replace the parameters marked above in {.....} with actual values and it should work fine for you. Let me know if you still see problems.

  Thanks

  Hi all,

  I just went ahead and tried submitting an XMLPost request to my web service through a Live Gadget and it worked !! So, it seems the days of XMLPost not working are actually over.

  I just took the code sample from the Live Gadget API reference and replaced the sample service and sample method name with the names of my service and method and it worked like a charm.

  Thanks
