B4R Question passing value to php backend

[sorex]

Hello,

What's an good method to pass a value to a php based backend?

I have the .download & .post options via the HttpJob class but ...

I can't seem to concat a value to the url string in B4R for the download option

I don't know what this payload array is for the post option.

Should I pass the value by using additional headers or are there other methods that I'm not aware of yet?

from the moment that I add the HttpJob class to my project my project doesn't compile anymore.

I have rCore, rESP8266Wifi, rMFRC522 & rRandomAccessFile libs selected.

I don't know what went wrong earlier but now it compiles and runs fine.

The only problem I noticed is that the POSTing doesn't work and doesn't send over the values.

Via GET it worked right away.

Here's an example on how to do it especially the concatenating is different to what we're used to and took me a while to figure out.

Sub sendTag(Tag As String)
    Dim url As String=JoinStrings(Array As String("http://192.168.0.9/rfid.php?op=writeID&id=",Tag))
    HttpJob.Download(url)   
End Sub

The only problem I noticed is that the POSTing doesn't work and doesn't send over the values.

The php-Script must be configured properly to accept poststring.
Usually the best way to work with a PHP-Script is to use POST-Requests (PostMultipart) and get the Post-Values in PHP....
How does the PHP Code look like?

 

[sorex]

like this but with POST instead of GET.

$op="";
if (isset($_GET["op"])) {$op=$_GET["op"];}

switch ($op) {
case "":showID();break;
case "writeID":writeID();break;
case "readID":readID();break;
}

using print_r($_POST); (and GET) showed that the collection was just empty.

 

[DonManfred]

using print_r($_POST); (and GET) showed that the collection was just empty.

I always use $_REQUEST to get values from a multipartpost Request. And i do use PHP a lot in my Apps as a DB-Bridge (man in the middle)

    if (isset($_REQUEST['viewall'])){$viewall=intval($_REQUEST['viewall']);} else {$viewall=0;}
    if (isset($_REQUEST['action'])){$action=$_REQUEST['action'];} else {$action="init";}
    if (isset($_REQUEST['zusatzID'])){$zusatzID=intval($_REQUEST['zusatzID']);} else {$zusatzID=0;}

Maybe rokhttputils is always sending GET Requests? Don´t know; never used B4R so far...

 

[sorex]

using

echo "----------------".chr(10);
print_r($_POST);
echo "----------------".chr(10);
print_r($_GET);
echo "----------------".chr(10);
print_r($_REQUEST);

results in

Wierd. Maybe a php-configuration problem?

 

[DonManfred]

are you giving any POST Values or GET Values to the php-script?

 

[sorex]

it's currently working with .download(url+parameters) which is currently fine as I will never get to the size boundary of the get request.

it doesn't work when using .post(url,parameters) as mentioned above.

maybe it needs to be in a specific format but all the examples I found seemed to use a plain string altho it mentiones that it needs to be a byte array.
