Sending a file to a web page using POST method

[FlyNn]

Hi Advanced users,

I have an application and I would like it to send a file to a web page using POST method.
I've found the HttpClient from Apache, but I had no luck. All the tutorials and samples I can find on the net are for 3.x. I've tried adopting the samples with the HttpClient 4.1 docs, but I failed.

I have a target url of a page and source file path. I get the basic idea of what needs to happen, I am just finding it hard to implement it.

Any help would be appreciated, Thanks.

Some code might help...along with what you mean by "I had no luck".

File file = new File("target file location");
                String targetURL = "URL to a .php web page";

                HttpClient httpclient = new DefaultHttpClient();
            try {
            HttpPost httppost = new HttpPost(targetURL);

            InputStreamEntity reqEntity = new InputStreamEntity(
                    new FileInputStream(file), -1);
            reqEntity.setContentType("binary/octet-stream");
            reqEntity.setChunked(true);
            // It may be more appropriate to use FileEntity class in this particular
            // instance but we are using a more generic InputStreamEntity to demonstrate
            // the capability to stream out data from any arbitrary source
            //
            // FileEntity entity = new FileEntity(file, "binary/octet-stream");

            httppost.setEntity(reqEntity);

            System.out.println("executing request " + httppost.getRequestLine());
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity resEntity = response.getEntity();

            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());
            if (resEntity != null) {
                System.out.println("Response content length: " + resEntity.getContentLength());
                System.out.println("Chunked?: " + resEntity.isChunked());
            }
            EntityUtils.consume(resEntity);
        } finally {
            // When HttpClient instance is no longer needed,
            // shut down the connection manager to ensure
            // immediate deallocation of all system resources
            httpclient.getConnectionManager().shutdown();
        }

I keep getting 406 Not Acceptable Response.

EDIT: This is essentially one of the examples from http://hc.apache.org/httpcomponents-.../examples.html

Which means the server is trying to return something the client has told it it can't accept.
What data is the server trying to return?

[FlyNn]

That's a very good questions cause I did not write the .php page on the server side. I do know it processes at the file and echos the contents out.

You should be able to find out what the Accept: header is for your post, though I couldn't tell you exactly how.
Then you'll need to find a way of seeing what the server is planning on sending.
If it's echoing your file back then I suspect it may be whatever MIME type that would fall under.

I have changed the code like this:

HttpClient httpclient = new DefaultHttpClient();
                
                try {
                    
                    HttpPost httppost = new HttpPost(targetURL);

                    FileEntity fe = new FileEntity(file,"text/xml; charset=\"UTF-8\"");

                    httppost.setEntity(fe);

                    System.out.println("executing request " + httppost.getRequestLine());
                    HttpResponse response = httpclient.execute(httppost);

                    HttpEntity resEntity = response.getEntity();

                    System.out.println("----------------------------------------");
                    System.out.println(response.getStatusLine());

                        if (resEntity != null) {
                            System.out.println("Response content length: " + resEntity.getContentLength());
                            System.out.println("Chunked?: " + resEntity.isChunked());
                        }

                    EntityUtils.consume(resEntity);
                    
                }catch(Exception e){
                    e.printStackTrace();
                } finally {
                    httpclient.getConnectionManager().shutdown();
                }

I have added the fileEntity and setting it for the httppost and correctly executing it.
I get 200 OK response.

Thank you
