Cordova FileTransfer sends file but nothing received

问题

I'm sending a video recorded via Cordova's MediaCapture plugin to a remote server via the FileTransfer plugin, but nothing - neither the file, nor any data whatsoever - is arriving at the server end. The server receives the request, but it seems to be empty.

According to Cordova, everything goes fine. Here's the readout from the success callback:

And here's my JS: (mediaFiles[0] is the captured video file)

var options = new FileUploadOptions();
options.fileName = 'foo.bar';
options.mimeType = mediaFiles[0].type;
options.params = {
    mime: mediaFiles[0].type
};

var ft = new FileTransfer();
ft.upload(
    mediaFiles[0].fullPath,
    encodeURI("http://xxxxxx.com/receive-video.php"),
    function (r) {
        console.log(r);
        alert('sent file!');
    },
    function (error) {
        alert('error');
        console.log(error);
    },
    options,
    true
);

(Note the last param, trustAllHosts, is set to true since my test server is self-signed.)

Cordova clearly thinks it's sent data, but my PHP script disagrees. Here's my PHP:

file_put_contents(
    'readout.txt',
    "Payload\n----------\n".
    file_get_contents('php://input').
    "\n\nRequest\n----------\n".
    print_r($_REQUEST, 1).
    "\n\nFiles\n----------\n".
    print_r($_FILES, 1).
    "\n\nPost\n----------\n".
    print_r($_POST, 1)
);

As you can see, I'm looking pretty much everywhere. All these result in empty readouts, however, in readout.txt.

What am I doing wrong?

回答1:

It turned out the chunkedMode param (in options) was the culprit.

In case this helps anyone else, disable this (it's true by default) and all should be fine.

options.chunkedMode = false;

Not sure how to explain the behaviour of the empty request with it turned on, though. The param exists to send the file in chunks, to allow for progress feedback of some sort.
