具有不同文件格式的Android HTTP Post文件

Question

Currently, I could HTTP Post text files and Image files using the following code snippets from http://www.codeofaninja.com/2013/04/android-http-client.html

Android portion:

// the file to be posted
String textFile = Environment.getExternalStorageDirectory() + "/sample.txt";
Log.v(TAG, "textFile: " + textFile);

// the URL where the file will be posted
String postReceiverUrl = "http://yourdomain.com/post_data_receiver.php";
Log.v(TAG, "postURL: " + postReceiverUrl);

// new HttpClient
HttpClient httpClient = new DefaultHttpClient();

// post header
HttpPost httpPost = new HttpPost(postReceiverUrl);

File file = new File(textFile);
FileBody fileBody = new FileBody(file);

MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("file", fileBody);
httpPost.setEntity(reqEntity);

// execute HTTP post request
HttpResponse response = httpClient.execute(httpPost);
HttpEntity resEntity = response.getEntity();

if (resEntity != null) {

    String responseStr = EntityUtils.toString(resEntity).trim();
    Log.v(TAG, "Response: " +  responseStr);

    // you can add an if statement here and do other actions based on the response
}

PHP portion:

<?php
// if text data was posted
if($_POST){
    print_r($_POST);
}

// if a file was posted
else if($_FILES){
    $file = $_FILES['file'];
    $fileContents = file_get_contents($file["tmp_name"]);
    print_r($fileContents);
}
?>

Using the above code snippets HTTP Post of textfiles and Images could be done without any issue. But if I try to HTTP Post other file formats like encrypted file etc. It fails and the file doesn't get posted to the backend.

Any idea what's the issue?

Thanks In Advance

Ok managed to solve it.

In your php.ini file change the following values:

upload_max_filesize & post_max_size

Change it to a more appropriate values depending on the expected filesize.

And it could work!!
