无法发送json作为guzzle post body

Solved 这与ecomdash api一起使用，因为在使用此方法时，所有json字符串必须用方括号括起来，就好像有一个产品数组一样 . 因此，对于产品数组，这实际上与json_encode一样正常工作，但只有一个产品正在更新，您必须手动添加json周围的方括号 . 因此，在设置请求时，您必须使用body而不是json . 所以这里是最终的代码 .

$data[] = array("Sku" => "067567", "Quantity" => 21, "WarehouseId" => 28345);
    $dataJson = json_encode($data);

    //put square brackets in if only one product is being updated
    if(count($data) == 1) {
      $dataJson = '['.$dataJson.']';
    }

    $headers = $this->auth;
    $headers['Content-Type'] = 'application/json';
    $params = array('headers' => $headers,
                    'json' => $data);

    $response = $this->client->request('POST', 'inventory/updateQuantityOnHand', array('headers' => $headers, 'body' => $dataJson));

    var_dump(json_decode($response->getBody(), true));
    die();
  }

我已经到处搜索并尝试了一百万件事情，但在尝试使用guzzle发送json作为POST请求时，我仍然遇到同样的错误 .

我发送的 Headers 只是我正在使用的api的凭据，他们正在处理其他请求，所以我不认为它们是问题所在 .

这是我用过的一些代码 .

$data = array("Sku" => "067567", "Quantity" => 10, "WarehouseId" => 
  28345);
$dataJson = json_encode($data, JSON_FORCE_OBJECT);
$headers = $this->auth;
$headers['Content-Type'] = 'application/json';
$params = array('headers' => $headers,
                'body' => $dataJson);

$response = $this->client-
   >post('inventory/updateQuantityOnHand',$params);



$data = array("Sku" => "067567", "Quantity" => 10, "WarehouseId" => 
  28345);
$headers = $this->auth;
$headers['Content-Type'] = 'application/json';
$params = array('headers' => $headers,
                'json' => $data);

$response = $this->client-
  >post('inventory/updateQuantityOnHand',$params);

我得到的错误是

我使用的是Guzzle版本6.2.1

在此先感谢任何帮助，这对我造成了伤害 .
