Opscode Chef REST API无效JSON

Question

I am trying to integrate with Chef via PHP

I used the library https://github.com/dv1r/php-chef to communicate with the Hosted Enterprise Chef. When I retrieve information from Chef, everything is fine. I can also delete clients and such.

The problem starts when I try to send data to the server. I always get the error "Invalid JSON". The JSON that I am sending is valid according to http://jsonlint.com/ .

Does anybody know if i need to add and encoding type to the json_encode() inorder to fix this?

Code example:

    try{
        // Gets current data in Data-Bad `evns` Item `dev` (works)
        $res = $this->chef->get('/data/envs/dev');
    } catch (Exception $e){
        echo("Exception: ".$e->getMessage());
    }
    // Alter Data
    $res->testtt = "testess";
    try{
        // Set's new data to Data-bag `envs` Item `dev` (FAILS)
        $ret = $this->chef->put("/data/envs/dev",$res);
    } catch (Exception $e){
        die("Exception: <br>".$e->getMessage());
    }

The interesting part of the library:

    // json encode data
    if ($data && !is_string($data)) {
        $data = json_encode($data,JSON_UNESCAPED_UNICODE);
        $this->debug("data encoded to json: {$data}");
    }

    // sign the request
    $this->sign($endpoint, $method, $data, $header);
    $this->debug("request URL: {$url}");
    // initiate curl
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $this->timeout);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);

    // most people are using self-signed certs for chef, so its easiest to just
    // disable ssl verification
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

    // add data to post and put requests
    if ($method == 'POST' || $method == 'PUT')
    {
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    }

    // execute
    $raw_response = curl_exec($ch);

If I missed some critical information, please comment and I will add.

Thank you.

EDIT: More debug info -

Raw Responses:

First call to the API (GET) raw_response: {"name":"name","id":"dev"}

Second call (PUT) raw_response: {"error":["invalid JSON"]}

Answer 1

The $res->testtt will be your main problem.

The 'magic' conversion is somehow buggy. Cast to array and you'll be safest on what is done

i.e:

try{
    // Gets current data in Data-Bad `evns` Item `dev` (works)
    $res = (array) $this->chef->get('/data/envs/dev');
} catch (Exception $e){
    echo("Exception: ".$e->getMessage());
}
// Alter Data
$res['testtt'] = "testess";
try{
    // Set's new data to Data-bag `envs` Item `dev` (FAILS)
    $ret = $this->chef->put("/data/envs/dev",$res);
} catch (Exception $e){
    die("Exception: <br>".$e->getMessage());
}

Hope it will help.

Edit for a working exemple

<?php
 $envs = unserialize($_POST['envs']);
 foreach($_POST["datas"] as $env => $items) {
  ksort($items,SORT_NATURAL);
  $old = (array) $chef->get("/data/livraisons/".$env);
  $new = array_merge($old,$items);
  ksort($new,SORT_NATURAL);
  $chef->put("/data/livraisons/".$env,$new);
 }
?>

I hope it will help you figure it out ..

Warns:

1. I'm on an open source chef server (11.0.10), maybe that's the point (even if I doubt about it)
2. I'm using a slightly different version of the library which don't use constant with json_encode... see here: https://github.com/jenssegers/php-chef
