Trouble Sending using POST over Http Connection

[baran_khan]

Hi,

I am trying to send an xml String using HTTP Post method. The connection goes well and i receive HTTP_OK as response, but dont know why its not executing the php script where I am sending the data.

Presently I am testing by creating an empty text file on the server side when I hit the page with the POST data.

Here is the code for the two

PHP Code

<?
if($_POST !=NULL){
$file = fopen("text.txt","w+");
}
else{
echo "M here";
}
?>

Here is the code for the connection....




String response;
HttpConnection conn = null;
DataInputStream in = null;
DataOutputStream out = null;
try {
conn = (HttpConnection) Connector
.open("URL",Connector.READ_WRITE);
conn.setRequestMethod(HttpConnection.POST);
out = conn.openDataOutputStream();
out.write("barankhan".getBytes());
out.flush();
out.close();
Dialog.alert("rest"+conn.getResponseCode()+HttpConnection.HTTP_BAD_REQUEST);

in = conn.openDataInputStream();
byte[] data = new byte[200];
int numBytes = in.read(data);
StringBuffer responseBuffer = new StringBuffer();
in.close();
conn.close();
for (int i = 0; i < numBytes; i++) {
responseBuffer.append((char) data[i]);
}
response = responseBuffer.toString();
Dialog.alert(response);
} catch (IOException e) {
System.out.println("Here is exception" + e.getMessage());
}



Hope to hear something great!!!:smile:

hi.
please use [code] tags - it makes your code much easier to read.

have you tried to make y post using another client? webpage in the desktop browser?

is your php code executed?

Hi,

Thanks for the reply,

Yeah the PHP code is running perfectly on local machine...I have uploaded it to the server so that I can access it through blackberry. The thing is The code executes without any issues and I get HTTP 200 as the response i.e. HTTP_OK. But the file is not created, so I guess I am able to hit the URL but not able to assign the post variable.

I tried inputStream on the page and received the else part of the page executed as response.

Thanks for the reply!!

try adding

conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

[baran_khan]

Nope:-(

I did tried earlier...not working...i tried to send simple string, xml with the mentioned content type..but not working....

[Ivanov]

you have to send a key-value pair in your post like "name=barankhan"

this works for me:


<?php
$file = fopen("postvars.txt", "w");

foreach($_POST as $key => $value) {
print($key." => ".$value."\n");
fwrite($file, $key." => ".$value."\n");
}

fclose($file);
?>



...
conn = (HttpConnection) Connector.open(url,Connector.READ_WRITE);
conn.setRequestMethod(HttpConnection.POST);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
out = conn.openDataOutputStream();
out.write("name=me".getBytes());
out.flush();
out.close();

...

Okey,

Here is new thing about sending data over HTTP Connection. Now the requirement is to send an Image over the connection. I have managed to send it in chunks using Base64 encoding in the form of string, but when i asseble the same on the other side, it gets corrupted.

Any intelligent guesses about how we can achieve it.....8-)
