I am trying updload a picture from a Phonegap application to my Python
App Engine project. The phone app trys to upload the file but App
engine returns a "list index out of range" error. Most of this code
is very similar to some of the sample projects.
I have the following code on the App Engine side to handle the files,
class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
def post(self):
upload_files = self.get_uploads('file') # 'file' is file upload
field in the form
blob_info = upload_files[0]
self.redirect('/serve/%s' % blob_info.key())
And the following code on the PhoneGap side,
function uploadImage() {
var smallImage = document.getElementById('cameraImage');
if (smallImage.src && smallImage.src !== "") {
var f = new FileTransfer();
f.upload(smallImage.src, "http://testtest.appspot.com/
upload",
// success callback
function(result) {
document.getElementById('uploadProgress').innerHTML =
result.bytesSent + ' bytes sent';
alert(result.responseCode + ": " +
result.response);
},
// error callback
function(error) {
alert('error uploading file: ' + error.code);
},
// options
{ fileName: 'myImage.jpg',
params: { 'username':'jtyberg' }
});
}
}
The errir us as follows,
"POST /upload HTTP/1.1" 500 487 - "BlackBerry9550/5.0.0.469 Profile/
MIDP-2.1 Configuration/CLDC-1.1 VendorID/-1" "testtest.appspot.com"
