Re: issue with org.restlet.Client

Wed, 05 Sep 2007 14:33:09 -0700 

Hello Nicolas,
I've created the issue 357 (http://restlet.tigris.org/issues/show_bug.cgi?id=357). I've tried with a very simple HTTPS server (using jetty server connector) and was not able to reproduce your pb. 
Could you tell us more about your context : server, client connectors, etc.
Did you try to only get the cvs file? Did you try to create a new client instance just for getting the csv file? 

best regards,
Thierry Boileau


Hi,


first of all, kudos for your great work. We are using your framework 
intensively in our production environment and it works like a charm.



I have stumbled with an issue with org.restlet.Client, that you might be able 
to solve. We need to navigate through a website and retrieve a csv file in a
 3-step process: 
 + POST some credentials, inspect the response for a redirect, 
 + GET to the redirect and 
 + GET to a csv resource.


This is the code that hangs in the last GET for the csv file:

Form form = new Form();
form.add("organizationId", "xxxxx");
form.add("username", "CCCC");
form.add("password", "VVVVV");

Client ebcClient = new Client(Protocol.HTTPS);
Response loginResponse =
ebcClient.post("https://xxxxxxx.com/ebctest/login/LoginProcess.do";,
form.getWebRepresentation());
Reference reference = loginResponse.getRedirectRef();
ebcClient.get(reference);
String yearMonthDay = "2007/08/28";
Response reportResponse =
ebcClient.get("https://xxxxxx/DownloadReport/"+yearMonthDay+
"/overstock_test/PaymentBatchDetailReport.csv");


However the following equivalent code works perfectly fine:


HttpClient httpClient = new HttpClient();
PostMethod httpLoginPost = new
PostMethod("https://xxxxx/ebctest/login/LoginProcess.do";);
NameValuePair[] postData = {
 new NameValuePair("organizationId", "xxxxxx"),
 new NameValuePair("username", "xxxxxx"),
 new NameValuePair("password", "xxxxxx")
};

httpLoginPost.setRequestBody(postData);
httpClient.executeMethod(httpLoginPost);

String redirectLocation = 
httpLoginPost.getResponseHeader("location").getValue();
GetMethod getLogin = new GetMethod(redirectLocation);
httpClient.executeMethod(getLogin);

String yearMonthDay = "2007/08/28";
GetMethod csvGet = new
GetMethod("https://xxxxxx/ebctest/DownloadReport/"+yearMonthDay+
"/overstock_test/PaymentBatchDetailReport.csv");

httpClient.executeMethod(csvGet);

BufferedReader in = new BufferedReader(new
InputStreamReader(csvGet.getResponseBodyAsStream()));

    String line;
    while((line = in.readLine()) != null) {
      logger.debug(line);
    }
httpLoginPost.releaseConnection();
getLogin.releaseConnection();


This is the log where the org.restlet.Client hangs :
