network.request returns response without data in PHP

Hi there,

I am running into problems with my server communication.

My network.request command runs without any problem in the simulator and even returns a response 

in the networkListener.

The response shows that the simple string I sent to the server should be in the array server-side, but after checking, the array is empty.

My question now is why do I get a positive response from my networkListener, when there is no data in the array. How does the PHP script need to look like?

[lua]

– NETWORK

local function networkListener(event)

    if ( event.isError ) then

        print( “Network error!” )

    else

        print( "RESPONSE: "…event.response )

    end

end

local function sendToServer()

    local headers = {}

    headers[“Content-Type”] = “application/x-www-form-urlencoded”

    headers[“Accept-Language”] = “en-US”

    

    local params = {}

    params.headers = headers

    params.body = “message=hey”

    network.request( “http://exampleURL”, “POST”, networkListener, params)

end

[/lua]

Google “PHP empty POST array” and you will get a ton of hits about this issue. If your data is under 2K, perhaps use GET instead of POST.

i would change the way you send to the server in json format:

local headers = { ["Content-Type"] = "application/json", ["Accept-Language"] = "en-US", } local sendInfo={ ["message"]="hey", } local params = {} params.headers = headers params.body = json.encode( sendInfo ) }) local request=network.request( url, "POST", networkListener, params)

in server side you just need this:

$data = file\_get\_contents('php://input'); $json = json\_decode($data, true); $info = $json["message"];

$info should have the “hey” string.

Hi Rob, 

How to solve this problem if server give Forbidden message on Lua GET command.

Can you post the new code and copy/paste the error you’re getting?

What happens when you try to access the URL in a web browser?

Ok, as of right now no progress made…

I tried using different headers and making the php script look for those. I will 

post the code of both down below:

PHP

[lua]

<?php

if(empty($_SERVER[‘CONTENT_TYPE’])){

     $type = “application/x-www-form-urlencoded”;

     $_SERVER[‘CONTENT_TYPE’] = $type;

}

$data = file_get_contents(‘php://input’);

$json = json_decode($data, true);

$info = $json[“message”];

if (empty($info))

{

echo “empty”;

}

else

{

echo $info;

}

?>

[/lua]

Corona

[lua]

local headers = {

    [“Content-Type”] = “application/x-www-form-urlencoded”, 

    [“Accept-Language”] = “en-US”,

    }

    local sendInfo={

        [“message”]=“hey”,

    }

    local params = {}

    params.headers = headers

    params.body = json.encode( sendInfo )

    local request = network.request( “http://localhost/testMessage.php”, “POST”, networkListener, params)

[/lua]

the message in the browser is still empty, however I always get a response in the 

console in corona, Saying: “Response: hey”

Like it should be online.

change your headers to:

local headers = { ["Content-Type"] = "application/json", ["Accept-Language"] = "en-US", }

Thanks for your help, but unfortunately it still doesn’t work :confused:

Like is there something I may missed in a config file, or is it even possible 

to send information with the Corona Simulator?

Is there anything else I can try?

What I actually need is sending a json table to a php server, which then saves it into

a mySQL database, as well as a way to access this data from a device through the

application. Ideally I’d like to use a POST call.

As I said, I get a response which contains the array in the simulator consol, but the array server side is always empty…

Thanks for your help guys!
