HTTPClient
Class HTTPConnection

java.lang.Object
  HTTPClient.HTTPConnection

All Implemented Interfaces:: GlobalConstants, HTTPClientModuleConstants

public class HTTPConnection
extends java.lang.Object
implements GlobalConstants, HTTPClientModuleConstants

This class implements http protocol requests; it contains most of HTTP/1.1 and ought to be unconditionally compliant. Redirections are automatically handled, and authorizations requests are recognized and dealt with via an authorization handler. Only full HTTP/1.0 and HTTP/1.1 requests are generated. HTTP/1.1, HTTP/1.0 and HTTP/0.9 responses are recognized.

Using the HTTPClient should be quite simple. First add the import statement 'import HTTPClient.*;' to your file(s). Request can then be sent using one of the methods Head(), Get(), Post(), etc in HTTPConnection. These methods all return an instance of HTTPResponse which has methods for accessing the response headers (getHeader(), getHeaderAsInt(), etc), various response info (getStatusCode(), getReasonLine(), etc) and the reponse data (getData() and getInputStream()). Following are some examples.

If this is in an applet you can retrieve files from your server as follows:

     try
     {
         HTTPConnection con = new HTTPConnection(this);
         HTTPResponse   rsp = con.Get("/my_file");
         if (rsp.getStatusCode() >= 300)
         {
             System.err.println("Received Error: "+rsp.getReasonLine());
             System.err.println(new String(rsp.getData()));
         }
         else
             data = rsp.getData();

         rsp = con.Get("/another_file");
         if (rsp.getStatusCode() >= 300)
         {
             System.err.println("Received Error: "+rsp.getReasonLine());
             System.err.println(new String(rsp.getData()));
         }
         else
             other_data = rsp.getData();
     }
     catch (IOException ioe)
     {
         System.err.println(ioe.toString());
     }
     catch (ModuleException me)
     {
         System.err.println("Error handling request: " + me.getMessage());
     }

This will get the files "/my_file" and "/another_file" and put their contents into byte[]s accessible via getData(). Note that you need to only create a new HTTPConnection when sending a request to a new server (different host or port); although you may create a new HTTPConnection for every request to the same server this not recommended, as various information about the server is cached after the first request (to optimize subsequent requests) and persistent connections are used whenever possible.

To POST form data you would use something like this (assuming you have two fields called name and e-mail, whose contents are stored in the variables name and email):

     try
     {
         NVPair form_data[] = new NVPair[2];
         form_data[0] = new NVPair("name", name);
         form_data[1] = new NVPair("e-mail", email);

         HTTPConnection con = new HTTPConnection(this);
         HTTPResponse   rsp = con.Post("/cgi-bin/my_script", form_data);
         if (rsp.getStatusCode() >= 300)
         {
             System.err.println("Received Error: "+rsp.getReasonLine());
             System.err.println(new String(rsp.getData()));
         }
         else
             stream = rsp.getInputStream();
     }
     catch (IOException ioe)
     {
         System.err.println(ioe.toString());
     }
     catch (ModuleException me)
     {
         System.err.println("Error handling request: " + me.getMessage());
     }

Here the response data is read at leasure via an InputStream instead of all at once into a byte[].

As another example, if you have a URL you're trying to send a request to you would do something like the following:

     try
     {
         URL url = new URL("http://www.mydomain.us/test/my_file");
         HTTPConnection con = new HTTPConnection(url);
         HTTPResponse   rsp = con.Put(url.getFile(), "Hello World");
         if (rsp.getStatusCode() >= 300)
         {
             System.err.println("Received Error: "+rsp.getReasonLine());
             System.err.println(new String(rsp.getData()));
         }
         else
             data = rsp.getData();
     }
     catch (IOException ioe)
     {
         System.err.println(ioe.toString());
     }
     catch (ModuleException me)
     {
         System.err.println("Error handling request: " + me.getMessage());
     }

There are a whole number of methods for each request type; however the general forms are ([...] means that the enclosed is optional):

Head ( file [, form-data [, headers ] ] )
Head ( file [, query [, headers ] ] )
Get ( file [, form-data [, headers ] ] )
Get ( file [, query [, headers ] ] )
Post ( file [, form-data [, headers ] ] )
Post ( file [, data [, headers ] ] )
Post ( file [, stream [, headers ] ] )
Put ( file , data [, headers ] )
Put ( file , stream [, headers ] )
Delete ( file [, headers ] )
Options ( file [, headers [, data] ] )
