This example is provided by Kari Hoijarvi from WUSTL.

Download IronPython from http://www.codeplex.com/Wiki/View.aspx?ProjectName=IronPython

Save the following code into a file called sos2.py

to run the code:

  ipy
  >>>import sos2
  >>>sos2.test()

The sos2.py file:

import clr;
import System
clr.AddReferenceByPartialName("System.Data")
clr.AddReferenceByPartialName("System.Web")
clr.AddReferenceByPartialName("System.Xml")
from System import *
from System.IO import *
from System.Net import *
from System.Net.Sockets import *
from System.Text import *
from System.Xml import *

Accessing SOS with Basic Authentication - Ruby

Basic authentication in Ruby example.

This is using Ruby 1.8.4 which may be installed:

Windows: http://rubyforge.org/frs/?group_id=167

OSX: http://hivelogic.com/articles/2005/12/01/rubyrailslighttpdmysqltiger

Example XML to pass to the SOS is found http://eo1.geobliki.com/sosdemo

post_it(xml)


 def post_it( xml, user = "bob", pass = "test")
    url = URI.parse('http://eo1.geobliki.com/sos')
    req = Net::HTTP::Post.new(url.path)
    req.basic_auth(user, pass)
    req['Content-Type'] = "text/xml"
    req.body = xml
    @response = Net::HTTP.start(url.host, url.port){|http|
      http.request(req)
    }
    puts @response.body     

  end

Accessing SOS with Basic Authentication - Java

Basic authentication in Java example.

This uses JDK 5.0 and Apache jakarta commons libraries.

JDK download: http://java.sun.com/javase/downloads/index.jsp

Apache download: http://jakarta.apache.org/commons/index.html

Example XML to pass to the SOS is found http://eo1.geobliki.com/sosdemo

testPost(XML, "user", "password", false, "http://eo1.geobliki.com/sos");

If you are having issues with firewalls try changing the preempt to true to see if will work. This always sends the username/password with the request.

public static void testPost(String xml, String userName, String password, boolean preempt, String URL){
    HttpClient client = new HttpClient();
    HttpState state = client.getState();
    HttpClientParams params = client.getParams();
    params.setAuthenticationPreemptive(preempt);
    Credentials credentials = new UsernamePasswordCredentials(userName, password);
    state.setCredentials(null, null, credentials);
    PostMethod method = new PostMethod(URL);
    method.setRequestBody(xml);
    try {
        client.executeMethod(method);       
        Header[] headers = method.getResponseHeaders();
        for (Header header:headers){
            System.out.println(header.getName() + ":"+header.getValue());
        }
        String response = method.getResponseBodyAsString();
        System.out.println(response);
        method.releaseConnection();
    } catch (HttpException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }       
}
