php - Opscode Chef REST API JSON 无效

Question

我正在尝试通过 PHP 与 Chef 集成

我使用了库 https://github.com/dv1r/php-chef与 Hosted Enterprise Chef 通信。当我从 Chef 检索信息时，一切正常。我还可以删除客户端等。

当我尝试向服务器发送数据时，问题就出现了。我总是收到错误“无效的 JSON”。根据 http://jsonlint.com/，我发送的 JSON 是有效的.

有人知道我是否需要向 json_encode() 添加类型和编码类型才能解决这个问题吗？

代码示例:

    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());
    }

库中有趣的部分:

    // 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);

如果我遗漏了一些关键信息，请评论，我会补充。

谢谢。

首次调用 API (GET) raw_response: {"name":"name","id":"dev"}

第二次调用 (PUT) raw_response: {"error":["invalid JSON"]}

curl_getinfo($ch) [PUT] 的输出:

$res->testtt 将是您的主要问题。

“魔法”转换在某种程度上是错误的。转换到数组，你将最安全地完成所做的事情

即:

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());
}

希望对您有所帮助。

编辑工作示例

<?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);
 }
?>

希望能帮到你..

警告:

1. 我在一个开源 Chef 服务器 (11.0.10) 上，也许这就是点(即使我对此表示怀疑)
2. 我使用的是稍微不同的不使用 json_encode 常量的库版本...请参见此处: https://github.com/jenssegers/php-chef
