Greetings,
I am trying to setup a server connection from my BlackBerry Application . I was able to get a response code on the status of the server. Now i have a few values which i have to POST to the server
Its like a registration page values(username, password, age ) have to be sent to the server .
ConnectionFactory connFact = new Connect开发者_JAVA技巧ionFactory();
ConnectionDescriptor connDesc;
connDesc = connFact.getConnection(url);
if (connDesc != null)
{
HttpConnection httpConn;
httpConn = (HttpConnection)connDesc.getConnection();
try
{
final int iResponseCode = httpConn.getResponseCode();
UiApplication.getUiApplication().invokeLater(new Runnable()
{
public void run()
{
Dialog.alert("Response code: " + Integer.toString(iResponseCode));
}
});
}
catch (IOException e)
{
System.err.println("Caught IOException: " + e.getMessage());
}
}
Thats the code i used to get the response code. I would appreciate it if someone could help me how i can make a POST request to the server.. the server url for status was company.com/app/version/stats
when it for register it would be company.com/app/register
Thank you
What type of a POST do you use? If you are just passing key-value pairs, then it should be a POST of a "application/x-www-form-urlencoded" content-type.
So, what lacks youe code is:
1). Set a proper content-type on your connection:
httpConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
2). Prepare the content to be sent to the server via the POST:
URLEncodedPostData encPostData = new URLEncodedPostData("UTF-8", false);
encPostData.append("username", username);
encPostData.append("password", password);
encPostData.append("age", age);
byte[] postData = encPostData.toString().getBytes("UTF-8");
3). Set content-length for the connection (this step may be optional - try without this first, probably the BB OS is smart enough to set this automatically):
httpConn.setRequestProperty("Content-Length", String.valueOf(postData.length));
4). Open an OutputStream and write the content to it (the code is simplified):
OutputStream os = httpConn.openOutputStream();
os.write(postData);
os.flush();
...
httpConn = (HttpConnection)connDesc.getConnection();
httpConn.setRequestMethod(HttpConnection.POST);
httpConn.setRequestProperty("username",name);
httpConn.setRequestProperty("password",pass);
....
