post数组数据：

$post = [
    "order_key" => [
        "order_number_type" => 1,
        "mchid" => "1646111***",
        "out_trade_no" => "20230721101459***"
    ],
    "logistics_type" => 2,
    "delivery_mode" => 1,
    "shipping_list" => [
        [
            "item_desc" => "玉米饭(1)"
        ]
    ],
    "upload_time" => "2023-07-21T10:35:43.575+08:00",
    "payer" => [
        "openid" => "o1hyC66giLDx****2frG9n9-****"
    ]
];

发起POST请求：

$res = Http::withHeaders(['Content-Type' => 'application/json;charset=UTF-8'])->post($url, $post);

返回状态正常，已经发货成功，但是在微信客户端服务通知中商品信息乱码，大佬么是怎么解决的？
