android testing HttpPost string for debugging purp

I'm trying to send data from my phone to mysql with HttpPost, but I don't have any server set up, so I was wondering if I can see what I'm sending exactly, and what it looks like. I'm a little familiar with JSON and the likes of how those look. So I'm curious as to what I'd be sending to mysql for debugging purposes.

public void sendDataDetail(View v){
    String name = nameText.getText().toString();

    if(name.length()>0){
        Log.w(TAG, name);
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://site/post.php");
        Log.w(TAG, "After HttpPost");
        try{
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            Log.w(TAG, "After list");
            nameValuePairs.add(new BasicNameValuePair("location","Los Angeles"));
            Log.w(TAG, "After location");
            nameValuePairs.add(new BasicNameValuePair("item_name",name));
            Log.w(TAG, "After item");
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            Log.w(TAG, "After nameValuePairs");
            httpclient.execute(httppost);
            nameText.setText(""); // clear text box, but this should be back to front page
        }catch(ClientProtocolException e){
            Log.w(TAG, e.getMessage());
        }catch(IOException e ){
            Log.w(TAG, e.getMessage());

        }
    }
}

As you can see I have a bunch of Logs to test if it goes through each line (not sure if this is even necessary =\ ). I was wondering if I can see what the httppost looks like, but it seems like it won't work if I do something like this

Log.w(TAG, httppost);

I get errors with that.

Any suggestions as to how I can test what I'm sending out to mysql for debugging?

Thanks in advance

Depending on the version of httpclient that you are using, there are going to be various ways of turning on 2 critical loggers:

httpclient.wire.header httpclient.wire

In one type of client, you can use java system properties to activate DEBUG level logging on the respective loggers almost always used by an HttpClient (headers & wire )...

 System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire.header", "debug");          System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire", "debug");

above will not work in all situations. For example on android, i use the client and, in order to activate logging for WIRE and for HEADERS, i have to recompile the 3rd party package, changing class= ch.boye.httpclientandroidlib.androidextra.HttpClientAndroidLog ( Log DEBUG ON | OFF )

sample block of logcat with both loggers turned on gives complete view of what's happening under the covers of http...

回答2:

in your IDE, such as Eclipse, put a breakpoint at httpclient.execute(httppost);

and then in the Expressions window, add the httppost variable, to see what the value is.

Now you can get rid of all that logging stuff
