CI Client Parsing JSON

Editing this question to make it clearer

Server A  
sends a JSON encoded array with the proper json http headers to ->

Server B  -
receives the JSON, does some db functions, returns an http status code to -> Server A

how does server B capture the JSON? is it capturing the HTTP body?
how do you tell codeigniter or PHP -- take the entire body of this message and convert it from JSON?
is there a message body function or something similar?

Can you tell what specific problem you have? Returning JSON is easy.

An example:

PHP Code:

 $tennisArray = array('Djokovic' => 1, 'Federer' => 2, 'Nadal' => 3, 'Murray' => 4);

 echo json_encode($tennisArray); //Take care you only echo JSON objects 


The code above will output the JSON formatted data like this:

Code:

{"Djokovic":1,"Federer":2,"Nadal":3,"Murray":4}

And if you need to encode an object, the following will probably do:

PHP Code:

 echo json_encode((array)$object); 


Good luck

thanks for response, my original question was confusing so i edited it above, hopefully i've made it clearer.

Your best bet is to have server A send a POST to Server B with the JSON string included in a field.

Server A sends a POST request to Server B with a field of say,

PHP Code:

$payload = json_encode($myData); 


Then on Server B at your endpoint, you grab it using either

PHP Code:

$_POST["payload"] 


or

PHP Code:

$this->input->("post"); 


It all depends on how you are sending the json encoded data to "server b". I'd just use a CURL request and use the POST type, or an ajax POST request. Then server b just checks for the $_POST['whatever'] in a controller, and runs json_decode() on it to get it back to a regular php array.

thanks for responses, creanium and cronix that sounds like best plan.

i am also trying to understand HTTP headers, body etc in terms of APIs. I googled and found this reference on stackoverflow  -- i think this is what i was imagining would happen

To access the entity body of a POST or PUT request (or any other HTTP method):

$entityBody = file_get_contents('php://input');
Also, the STDIN constant is an already-open stream to php://input, so you can alternatively do:

$entityBody = stream_get_contents(STDIN);

so i'm trying to understand the difference  -- with sending the JSON in a specific named post field - then server B is just looking for the same post field.

VERSUS the above -- is grabbing everything from the HTTP body?
