How can I get http request body data in codeigniter?

Question

I am having trouble getting JSON encoded data POSTed to my CI controller from my IOS obj-c client. I believe that my problem is the same as the one mentioned here. But I cannot find any documentation on a 'request' object on the CodeIgniter site. How can I view/parse the data in an http request body?

$this->request->body ??

Thanks!

Answer 1

I was able to get this working by using

$jsonArray = json_decode(file_get_contents('php://input'),true); 

The above will read the request body from the input request and then decodes the JSON to an associative array.

I would still be interested in refactoring this code if CI has a wrapper for reading input stream http body data as I am above. Fairly new to this framework.

Answer 2

Try to use $this->input->raw_input_stream

Answer 3

The "request" object mentioned in that post belongs to a package named "codeigniter-restserver". You can find more info here.

The accepted answer is a working one, but CodeIgniter does provide $this->input->raw_input_stream that gives you exactly what you need. So to write things the CodeIgniter way, you should use:

$jsonArray = json_decode($this->input->raw_input_stream, true);

And you'll notice that the source code of raw_input_stream also uses the file_get_contents('php://input') method.
