{
    "goods_list": "[{\"sku\":1003001442820970},{\"sku\":1003001442626969},{\"sku\":1003001442310851},{\"sku\":1003001445182314},{\"sku\":100300104903791},{\"sku\":1003001442626966},{\"sku\":1003001441414899},{\"sku\":1003001445184038},{\"sku\":1003001442658793},{\"sku\":1003001443446765}]\\",
}

The value of goods_list is a string, not an array.

As you defined, the json should be looked as below:

{
    "goods_list": [{"sku":1003001442820970},{"sku":1003001442626969}]
}
