You need to convert array into proper form after that apply json_encode()like below:
在应用之后，您需要将数组转换为正确的形式，json_encode()如下所示：
$arrSku = array('612552892' => array('quantity' => 1), '625512336' => array('quantity' => 10) );
$arrNewSku = array();
$incI = 0;
foreach($arrSku AS $arrKey => $arrData){
$arrNewSku[$incI]['sku_id'] = $arrKey;
$arrNewSku[$incI]['quantity'] = $arrData['quantity'];
$incI++;
}
//Convert array to json form...
$encodedSku = json_encode($arrNewSku);
print('<pre>');
print_r($encodedSku);
print('</pre>');
//Output:
[{"sku_id":612552892,"quantity":1},{"sku_id":625512336,"quantity":10}]
Hope this will work for you.
希望这对你有用。

Use $encodedSku = json_encode($request->sku);and you'll have a proper JSON instead of an Array.
使用$encodedSku = json_encode($request->sku);，您将拥有一个正确的 JSON 而不是数组。
