Issue Reading Http Request Body from a Json Post in PHP

Issue reading HTTP request body from a JSON POST in PHP

It turns out that I just needed

$inputJSON = file_get_contents('php://input');
$input = json_decode($inputJSON, TRUE); //convert JSON into array

where the second parameter in json_decode returned the object as an array.

PHP Get JSON POST Data

The following is working for me now:

$inputJSON = file_get_contents('php://input');
$input= json_decode( $inputJSON ); 

I think my issue was using:

$input= json_decode( $inputJSON, TRUE ); 

instead of just:

$input= json_decode( $inputJSON ); 

php can't read http post request body

I solved that. Basically I just created a new user table and it worked like magic.

How to access a JSON request body of a POST request in Slim?

Generally speaking, you can access the POST parameters individually in one of two ways:

$paramValue = $application->request->params('paramName');

or

$paramValue = $application->request->post('paramName');

More info is available in the documentation: http://docs.slimframework.com/#Request-Variables

When JSON is sent in a POST, you have to access the information from the request body, for example:

$app->post('/some/path', function () use ($app) {
    $json = $app->request->getBody();
    $data = json_decode($json, true); // parse the JSON into an assoc. array
    // do other tasks
});

Reading JSON POST using PHP

You have empty $_POST. If your web-server wants see data in json-format you need to read the raw input and then parse it with JSON decode.

You need something like that:

$json = file_get_contents('php://input');
$obj = json_decode($json);

Also you have wrong code for testing JSON-communication...

CURLOPT_POSTFIELDS tells curl to encode your parameters as application/x-www-form-urlencoded. You need JSON-string here.

UPDATE

Your php code for test page should be like that:

$data_string = json_encode($data);

$ch = curl_init('http://webservice.local/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($data_string))
);

$result = curl_exec($ch);
$result = json_decode($result);
var_dump($result);

Also on your web-service page you should remove one of the lines header('Content-type: application/json');. It must be called only once.

Sending a POST request with JSON body using Guzzlehttp

The startpoint of the payload data should be an array in order to encode it to json. Otherwise you might encounter problems since you are then trying to encode data already in json format.

Step-1) Create a variable $payload where you store the data you wish to send with your request.

Step-2) Add body into your request (below headers), where $payload is your data, and json-encode the $payload.

'body'    => json_encode($payload)

To simplify the test you can also just add the pure text string.

'body' => json_encode('mydata goes here...')

POST request with JSON body

You need to use the cURL library to send this request.

<?php
// Your ID and token
$blogID = '8070105920543249955';
$authToken = 'OAuth 2.0 token here';

// The data to send to the API
$postData = array(
    'kind' => 'blogger#post',
    'blog' => array('id' => $blogID),
    'title' => 'A new post',
    'content' => 'With <b>exciting</b> content...'
);

// Setup cURL
$ch = curl_init('https://www.googleapis.com/blogger/v3/blogs/'.$blogID.'/posts/');
curl_setopt_array($ch, array(
    CURLOPT_POST => TRUE,
    CURLOPT_RETURNTRANSFER => TRUE,
    CURLOPT_HTTPHEADER => array(
        'Authorization: '.$authToken,
        'Content-Type: application/json'
    ),
    CURLOPT_POSTFIELDS => json_encode($postData)
));

// Send the request
$response = curl_exec($ch);

// Check for errors
if($response === FALSE){
    die(curl_error($ch));
}

// Decode the response
$responseData = json_decode($response, TRUE);

// Close the cURL handler
curl_close($ch);

// Print the date from the response
echo $responseData['published'];

If, for some reason, you can't/don't want to use cURL, you can do this:

<?php
// Your ID and token
$blogID = '8070105920543249955';
$authToken = 'OAuth 2.0 token here';

// The data to send to the API
$postData = array(
    'kind' => 'blogger#post',
    'blog' => array('id' => $blogID),
    'title' => 'A new post',
    'content' => 'With <b>exciting</b> content...'
);

// Create the context for the request
$context = stream_context_create(array(
    'http' => array(
        // http://www.php.net/manual/en/context.http.php
        'method' => 'POST',
        'header' => "Authorization: {$authToken}\r\n".
            "Content-Type: application/json\r\n",
        'content' => json_encode($postData)
    )
));

// Send the request
$response = file_get_contents('https://www.googleapis.com/blogger/v3/blogs/'.$blogID.'/posts/', FALSE, $context);

// Check for errors
if($response === FALSE){
    die('Error');
}

// Decode the response
$responseData = json_decode($response, TRUE);

// Print the date from the response
echo $responseData['published'];
