Not really. All App Engine applications are just web services, whether made with a plugin or not. They are accessed via HTTP requests, and return HTTP responses. There's nothing hidden, magical, or secret about how that's done. The whole World Wide Web is built on the very public HTTP standard. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

I do understand how browsers work:) Unfortunately the request sent by the web browser is quite hidden by Google App Engine plugin in all the html/java script unfriendly looking files it creates for you. I even do not know the name of the parameter of this default google app engine project. What I am asking is not a program in C#, but a simple concrete example in ANY language for sending this POST request in any format you wish. Interpreting the returned results is not needed (but details are important, like the parameter name).

here's a decent example of how to use C# to authenticate using Google ClientLogin. There enough code in there to see how you would GET/POST against HTTP endpoints as well http://dalelane.co.uk/blog/?p=894 we use C# (but any language would do) for our client libraries and bulkloader and its been working great cheers brian On Aug 18, 5:51 am, Vassili vassi...@gmail.com wrote: I do understand how browsers work:) Unfortunately the request sent by the web browser is quite hidden by Google App Engine plugin in all the html/java script unfriendly looking files it creates for you.

Thanks for the link. So is it so hidden? Has anyone been able to decode the Webservice beyond the default project created with the Eclipse plugin? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: How to write a C# client to access google app engine?
OK guys and gals, I got it! If you also use google app engine plugin
for Eclipse, read on since there is a hack I have not found anywhere
else out there.
Here is the answer in C#:
WebRequest request = WebRequest.Create(http://
1.latest.myapp.appspot.com/appname/greet);
request.Credentials = CredentialCache.DefaultCredentials;
request.Method = POST;
request.ContentType = text/x-gwt-rpc; charset=utf-8;
string content = 5|0|6|http://1.latest.myapp.appspot.com/
myapp/|AF76B9CA2759BDA4DBA207D5542054B2|myapp.client.GreetingService|
greetServer|java.lang.String/2004016611|ThisIsAParameterValue|1|2|3|4|
1|5|6|;
byte[] contentBytes =
System.Text.UTF8Encoding.UTF8.GetBytes(content);
request.ContentLength = contentBytes.Length;
using (Stream stream = request.GetRequestStream())
{
stream.Write(contentBytes, 0, contentBytes.Length);
}
WebResponse response = request.GetResponse();
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);
reader.Close();
response.Close();
The hacky part here is the content string, especially the magic guid
AF76B9CA2759BDA4DBA207D5542054B2.
You will (very probably) have a different guid. To figure out what you
need to submit for the request do the following:
- either print the value of request.getInputStream() from your servlet
when you get a request
- or go to war/yourapp/anotherguid.cache.html (this file is created
when you compile your project) and look for the mS parameter defined
there
The question remains why Google made it so complicated? Or am I
missing something and there is a much simpler solution?
Cheers,
Vassili

[google-appengine] Re: How to write a C# client to access google app engine?
I'm not sure what you're talking about with respect to decoding the Webservice, but my application uses a c# client to access it. Here is the c# code where it accesses it: HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url); req.Method = GET; req.KeepAlive = false; using (var respstream = req.GetResponse().GetResponseStream()) return respstream.ReadFully(); ReadFully is just an extension method that fully reads a stream.

You need to understand how browsers work - in a nutshell, they send a request for a URL, and the server returns data. In most cases this data is HTML code to be rendered by your browser, but you can in fact make it anything you want - XML, JSON or a custom data format.
