Hi,
We have an urgent requirement to embed Internet explorer
with our IDE developed using Eclipse. We are using the
webbrowser eclipse plugin to do so. As of now, all "http get"
requests are working fine but sending "http post" requests is
not working. The server on the other side is still getting the
request as "http get". I guess we are not setting up the postData
argument correctly.
There are lot of examples explaining how to create and send
a "get" request but could not find any for "http post".
Does anybody have sample code for this (http post)?
Any help/pointers will be greatly appreciated.
thanks,
Devendra

Hi,
Here is a way to do a post in code. This is java stuff - not eclipse.
This post is done in code.
// Construct data - I need to encode it in my app.
String data = URLEncoder.encode("logon", "UTF-8") + "=" +
URLEncoder.encode(app.codeAgence, "UTF-8"); //$NON-NLS-1$ //$NON-NLS-2$
//$NON-NLS-3$ //$NON-NLS-4$
data += "&" + URLEncoder.encode("old", "UTF-8") + "=" +
URLEncoder.encode(app.passeAgence, "UTF-8"); //$NON-NLS-1$ //$NON-NLS-2$
//$NON-NLS-3$ //$NON-NLS-4$ //$NON-NLS-5$
data += "&" + URLEncoder.encode("new", "UTF-8") + "=" +
URLEncoder.encode(newPswd, "UTF-8"); //$NON-NLS-1$ //$NON-NLS-2$
//$NON-NLS-3$ //$NON-NLS-4$ //$NON-NLS-5$
data += "&" + URLEncoder.encode("new2", "UTF-8") + "=" +
URLEncoder.encode(newPswd, "UTF-8"); //$NON-NLS-1$ //$NON-NLS-2$
//$NON-NLS-3$ //$NON-NLS-4$ //$NON-NLS-5$
// Send data
URL url = new URL("https://" + YOUR_URL); //$NON-NLS-1$ //$NON-NLS-2$
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();

Thanks much Veronika.
I am trying to make it work as per the sample code in the bug report.
Here's the sample code I was experimenting with :
------- <snip> --------
public void testPostRequest(){
int[] httpArgs = webBrowser.getIDsOfNames(new String[]{ "Navigate",
"URL", "Flags", "TargetFrameName", "Postdata", "Headers"});
int dispIdMember = httpArgs[0]; // Navigate
Variant[] paramVals = new Variant[3];
int[] paramNames = new int[3];
paramNames[0] = httpArgs[1]; // URL
paramVals[0] = new Variant("http://10.33.4.68:5555/");
paramNames[1] = httpArgs[5]; // HEADERS
paramVals[1] = new Variant("Content-Type: text/html");
String sPostData = "login=try&password=catch";
paramNames[2] = httpArgs[4]; // PostData
paramVals[2] = new Variant(sPostData);
webBrowser.invoke(dispIdMember, paramVals, paramNames);
}
------- </snip> --------
This webbrowser control generates the the following http request for this :
------------------
GET / HTTP/1.0
Accept: */*
Accept-Language: en-us
Content-Type: text/htmlAccept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR
1.0.3705)
Host: 10.33.4.68:5555
Cache-Control: max-age=259200
Connection: keep-alive
---------------------
regards,
Devendra

According to the MSDN:
http://msdn.microsoft.com/library/default.asp?url=/workshop/ browser/webbrowser/reference/ifaces/iwebbrowser2/navigate.as p
"The post data specified by PostData is passed as a SAFEARRAY Data Type
structure. The VARIANT should be of type VT_ARRAY and point to a SAFEARRAY
Data Type. The SAFEARRAY Data Type should be of element type VT_UI1,
dimension one, and have an element count equal to the number of bytes of
post data."
Bug 10977 talks about how to get the data out of a safearray of type VT_U1.
You will have to do the reverse and create a safearray of this type. If I
get a few minutes, I will hack up an example but don't wait for me - you can
probably figure this out on your own.
