[android-developers] Re: HTTP POST to Web Server running on Android Device
line=POST / HTTP/1.1
line=Content-Length: 23
No you would see:
line=POST / HTTP/1.1
line=Content-Length: 23
line=0
if a null was returned.
But a null is never returned. Still your
loop ends as instead an exception is trown.
You did not see that because the catch does nothing.
Add a Log.i there and you will see.
You modified the original code which checked for an empty line.
Take the original code again.
Add a check for the Content-Lengh: line and decode the contentlength.
(in your example 23)
Then outside the loop do something like:
[code]
if ( contentlength 0 ){
char [] buffer = new char[contentlength];
int nread = in.read (buffer, 0, contentlength);
String Parameters = new String( buffer);
// well you should check nread == contentlength
}
[/code]
I am wondering where the HTTP POST data is?
That just follows the empty line. But as that data is not ended with
a newline in.readLine() cannot be used.

Still your loop ends as instead an exception is trown
which you did not see because the catch statement is empty.
Add a Log.i there and you will see.
You modified the original code where the loops ends
at the first empty line. Take the original code again
en check for the Content-Length line. Parse out
the value for contentlength;
After the loop add following code
[code]
if ( contentlength 0 ) {
char [] buffer = new char[contentlength];
int nread = in.read (buffer, 0, contentlength);
String Parameters = new String( buffer);
// well you should check if nread equals contentlength
}
[/code]

That just follows the empty line. But as this post data is
not terminated with a newline character in.readLine() cannot
be used.

Hi All,
I am trying to send a HTTP POST command from Android Device A to
Android Device B. Device B is running a simple web server. The code
that I am using for the webserver is
here:http://code.google.com/p/android-webserver/
I am adding functionality to the code for it to process HTTP POST
commands, currently it only supports HTTP GET.
In order to send my HTTP POST command from Device A, I do the
following:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
try {
ListNameValuePair pairs = new ArrayListNameValuePair();
pairs.add(new BasicNameValuePair(key1, value1));
pairs.add(new BasicNameValuePair(key2, value2));
httppost.setEntity(new UrlEncodedFormEntity(pairs));
HttpResponse httpresponse = httpclient.execute(httppost);}
catch (IOException e) {
e.printStackTrace();
}
In Device B, I have opened an input stream from a socket in Java. I
am printing out all the lines that I am receiving via the socket. The
code looks as follows:
try {
in = new BufferedReader(new
InputStreamReader(toClient.getInputStream()));
// Receive data
while (true) {
String s = in.readLine().trim();
Log.i(TAG, line= + s);
if(s==null) {
break;
}
}
}
When I run the webserver on Device B and run the snippet of code
posted above on Device A, the only output of the webserver that I get
is:
line=POST / HTTP/1.1
line=Content-Length: 23
I am wondering where the HTTP POST data is? Shouldn't I be able to
see it in the printout? It seems like I am only seeing the HTTP
header.
Thanks in advance for your help,
K
