Is it possible use HttpUtils2 to upload file?

sally3599 · Aug 9, 2012

HttpUtils2 can post data, can it upload a big file?

You can add it as a GET parameter:

B4X:

job2.PostFile("http://ccotesting.site11.com/serTestUpload.php?FileName=file.zip", File.DirInternal, varZipFileUp)

You will need to use StringUtils.EncodeUrl to encode the file name (if it has spaces or other non-ASCII characters).

I think in the past I dealt with this by sending the fileName and the fileContent splitted by a "//" separator, then exploded the content in an array to set the file name.

This was a choice I used, but then decided to turn it off. I am always afraid of GET variables, in such operations

The POST payload is not more secure than the GET parameters. Especially when both are sent from an app and not seen in the browser.

There is a tiny difference in my opinion. If one has the link, she can experiment with the GET parameter. But anyway, I am not that concerned with the security problem. I am more concerned with accidental bad inputs with gets when a user uses a link outside of an app. This happened every day in a intranet app of mine

This is only relevant when the link is in the browser. Not inside the app.

What is the syntax when passing more than one variable using this approach? When I try

B4X:

job2.PostFile("http://ccotesting.site11.com/serTestUpload.php?FileName="&varZipFileUp&"Age="&i&"theSize="&varZipFileUpSize, File.DirInternal, varZipFileUp)

it assigns all three variables to FileName. Thanks.

mc73 · Nov 28, 2013

You should add & inside the quotes as well.

B4X:

"your.php?var1=" & yourVar1 & "&var2=" & yourVar2

and so on...

Erel · Nov 28, 2013

I recommend you to call StringUtils.EncodeUrl for each of the parameters. Will save you a few bug reports...

PHP:

 $FileName = $_GET['FileName'];

is not equal to

PHP:

 $PostData = file_get_contents("php://input");

To write the file to your upload directory you have to write the contents of $PostData to a file.

PHP:

$PostData = file_get_contents("php://input");
file_put_contents('/path/to/uploaddir/upload.zip', $PostData);

I didn´t worked with php://input in all the years... So i did not really know what $PostData do have as Content.
php-doku says it uses less memory than using $HTTP_RAW_POST_DATA.

I suggest debugging the contents of $_POST after uploading and getting the $PostData. Write a log and have a look at this log after uploading a file...
Remember that the log should be writte to a path where the script can write (chmod 777 or 644)

PHP:

$file_handle = fopen('./b4a_'.date("Y-W", time()).'.log', 'a+');
fwrite($file_handle, "======== POST-Data (RAW)====================="."\r\n");
fwrite($file_handle, "PostData = ".$PostData."\r\n");
fwrite($file_handle, "======== POST-Data ========================="."\r\n");
foreach($_POST as $name => $value){
  fwrite($file_handle, date("d.m.Y H:i:s", time()).": ".$name."=".$value." ".$add."\r\n");
}
fwrite($file_handle, "======== GET-Data ========================="."\r\n");
foreach($_GET as $name => $value){
  fwrite($file_handle, date("d.m.Y H:i:s", time()).": ".$name."=".$value." ".$add."\r\n");
}
fwrite($file_handle, "======================================"."\r\n");
fclose($file_handle);

Hello

I apologize but I am not able to upload a file, i.e. the JobDone event is not fired.
Where is my fauult?
hera the (simple code) whit some try, insertString and Download2, which works:

B4X:

    sendImg.Initialize("sendImgJob", Me)  
    sendImg.PostFile("http://rete.condorinformatique.com/upload.php?fileName=image.jpg",dir, fileName)
'    sendImg.PostString("http://rete.condorinformatique.com/upload.php", "&key2=value2&fileName=image.jpg")
'    sendImg.Download2("http://rete.condorinformatique.com/upload.php", _
'      Array As String("first key", "first value :)", "second key", "value 2"))
Sub JobDone (Job As HttpJob)
  ToastMessageShow("Done ", True)
  Log("JobName = " & Job.JobName & ", Success = " & Job.Success)
  Job.Release
End Sub

best regards

I've just tried this code and JobDone is raised:

B4X:

Sub Activity_Create(FirstTime As Boolean)
   Dim sendimg As HttpJob
   sendimg.Initialize("sendImgJob", Me)  
  sendimg.PostFile("http://rete.condorinformatique.com/upload.php?fileName=image.jpg", File.DirRootExternal, "1.xls")
End Sub
Sub JobDone (Job As HttpJob)
  Log("JobName = " & Job.JobName & ", Success = " & Job.Success)
  Job.Release
End Sub

rossati · May 14, 2014

Thanks
I have tried your script and my be one times worked, this get a strange answer:

B4X:

Sub Activity_Create(FirstTime As Boolean)
  Dim sendimg As HttpJob
  sendimg.Initialize("sendImgJob", Me) 
  sendimg.PostFile("http://rete.condorinformatique.com/upload.php?fileName=xximage.jpg", File.DirRootExternal, "image.jpg")
  sendimg.PostString("http://rete.condorinformatique.com/upload.php", "&key3=value2&fileName=image.jpg")
End Sub
Sub JobDone (Job As HttpJob)
  Log("JobName = " & Job.JobName & ", Success = " & Job.Success)
  Log(Job.GetString)
  Job.Release
End Sub

The answer is:

B4X:

** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
** Service (httputils2service) Create **
** Service (httputils2service) Start **
** Service (httputils2service) Start **
JobName = sendImgJob, Success = true
2047056561<pre>Array
(
)
Array
(
  [key3] => value2
  [fileName] => image.jpg
)
JobName = sendImgJob, Success = true

2132198191<pre>Array
(
)
Array
(
  [key3] => value2
  [fileName] => image.jpg
)
** Activity (main) Pause, UserClosed = false **

It seems two different instance of sendstring, here the PHP:

B4X:

<?PHP
echo rand()."<pre>";print_r($_FILES);
print_r($_REQUEST);
if (isset($_FILES['fileUpload']['name'])) {
    $flName = $_FILES['fileUpload']['name'];
    move_uploaded_file($_FILES['fileUpload']['tmp_name'],$flName );
}
?>

Timing problems? Android Samsung Version?

best regards

DonManfred · May 14, 2014

you should just use one of thesenot both

B4X:

 sendimg.PostFile("http://rete.condorinformatique.com/upload.php?fileName=xximage.jpg", File.DirRootExternal, "image.jpg")
  sendimg.PostString("http://rete.condorinformatique.com/upload.php", "&key3=value2&fileName=image.jpg")

rossati · May 15, 2014

thanks Manfred

this is a try, I have no answer if I use sendimg.PostFile and also if I invert the two instructions

regards John

Hi
I have the problem with post file that should be uploaded to ASP.NET page:

Dim job1 As HttpJob

job1.Initialize(
"Job1", Me)

'job1.PostFile(
"http://192.168.10.202/UniVend-Terminal/upload.aspx",File.DirRootExternal,"Cash00000027.txt")

The server gets the request but do not see any files.
At JobDone sub I get success.
When I send files from Windows PC application to the same page, the server sees the files.

What is wrong?

Erel · May 25, 2014

Job.PostFile sends a POST request with the file content as the POST payload. Which format is expected by your server?

Do you mean "GET" or "POST"? My server expects POST.

Is it possible use HttpUtils2 to upload file?
