Is it possible use HttpUtils2 to upload file?

sally3599 · Aug 9, 2012

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

Erel · Aug 9, 2012

Yes. HttpJob.PostFile can handle large files.

sally3599 · Aug 9, 2012

use PostFile to upload file

Thanks Erel.

Do you know what's input name($_FILES["file"]) for HttpJob.PostFile ?

Erel · Aug 9, 2012

You should use php://input

Erel · Aug 10, 2012

See the error message in the logs. The error is in the server side. It doesn't allow you to upload more than 2mb. There are several settings that affect the limit.

sally3599 · Aug 11, 2012

another error message

Is it right?

B4X:

jobPost.PostFile("http://website.com/b4a/upload.php",File.DirRootExternal,"1.zip")

it gave me another error message:

Do you know why it always show "/b4a/upload.php", the url was cut ?
Any help will be appreciate it.

Erel · Aug 11, 2012

The Basic4android code is correct.

The URL is made of two (or more) parts. The first is the host and the other is named here the resource.

Are you able to access this page with the browser?

sally3599 · Aug 12, 2012

the WebView1.LoadUrl can generate a file correctly on the server , but I don't know how to use HttpUtils2 to access that page.

B4X:

Sub Activity_Create(FirstTime As Boolean)
    WebView1.Initialize("WebView1")
    Activity.AddView(WebView1, 0, 0, 100%x, 100%y)
    If FirstTime Then
       LoadedUrl="http://website/b4a/upload.php"
    End If
End Sub

Sub Activity_Resume
    WebView1.LoadUrl(LoadedUrl)
End Sub

For PostString, I use test.php to write a file on the server:

B4X:

jobPost.PostString("http://website/b4a/test.php","number="&etNumber.Text)

the app show Success:

B4X:

08-13 03:32:18.100 I/B4A     ( 3808): JobName = JobPostName, Success = true

But actually it was fail too, nothing generate on the server!

Any help will be appreciate it.

Erel · Aug 13, 2012

Can you post the script in test.php?

sally3599 · Aug 13, 2012

test.php & upload.php

Attach file inckluded test.php and upload.php.
They will show alert and generate a empty file in directory of upload/ if run them directly.

Any help will be appreciate it.

Erel · Aug 13, 2012

Success means that the server returned the response code 200.

You should check the string returned from the server. It can be done with HttpJob.GetString.

You can use this PHP script to test the parameters:
http://www.b4x.com/print.php

sally3599 · Aug 13, 2012

Do you have the script print.php?

Thanks Erel.
Would you please post the script in print.php?

Erel · Aug 13, 2012

Here:

PHP:

<?php
print "POST variables:\r\n";
var_dump($_POST);
print "\r\nGET variables:\r\n";
var_dump($_GET);
?>

sally3599 · Aug 13, 2012

the Download2 and PostString of HttpJob are work

Thanks Erel.
The GET and POST of HttpJob are work.

B4X:

   'Send a GET request
   job1.Download2("http://www.b4x.com/print.php", _
      Array As String("first key", "first value :)", "second key", "value 2"))
   
   'Send a POST request
   job2.Initialize("Job2", Me)
   job2.PostString("http://www.b4x.com/print.php", "first key=first value&key2=value2")

But for the PostFile, it still show a error "Not Acceptable" :

B4X:

jobPost.PostFile("http://website.com/upload.php",File.DirRootExternal,"1.zip")

is the php script right?

PHP:

$str = file_get_contents('php://input', 'r');

This forum can't post entire content of this script, so I upload it in the attach file.
Any help will be appreciate it.

Erel · Aug 14, 2012

Google for the error message. It is related to your PHP server configuration.

sally3599 · Aug 14, 2012

Were can I find the error message from google?

Thanks Erel.

So you checked my php script, is it no problem?
The PHP server configuration made by cpanel, it's a general environment.

Where can I find the error message from google about "Not Acceptable"? Would you please post a URL about this?

Any help will be appreciate it.

sally3599 · Aug 14, 2012

it works.

Thanks Erel.

I use another cpanel server, it works now!

The reason came from Mod Seurity, because android send "Invalid character in request".

Hi. I'm using the following code to upload a zip file...

B4X:

job2.PostFile("http://ccotesting.site11.com/serTestUpload.php", File.DirInternal, varZipFileUp)

and I get no errors. Using the php code...

PHP:

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

I can see the contents of zip file in the B4A log. But if I use php code...

PHP:

$FileName = $_GET['FileName'];

nothing is returned. What can I do in my php code to recognize the uploaded zip file and move it to the upload directory? Thanks.

Is it possible use HttpUtils2 to upload file?
