$body->append();来自 POSTMAN API，如何用变量替换它？

Question

鉴于这个从邮递员生成的代码，$body->append();来自POSTMAN API，如何用变量替换它？

如何将 CURLOPT_POSTFIELDS 替换为 php 变量？所以可以用动态变量填充

最好的做法是什么？

谢谢

<?php

• json_decode 字符串成数组
• 根据需要修改值
• 为 CURLOPT_POSTFIELDS 设置该数据

类似的东西

$json = '{
    "RateRequest": {
        "ClientDetails" : null,
        "RequestedShipment": {
            "DropOffType": "REQUEST_COURIER",
            "ShipTimestamp": "2020-08-25T11:00:00GMT+02:00",
            "UnitOfMeasurement": "SI",
            "Content": "NON_DOCUMENTS",
            "PaymentInfo": "DAP",
            "NextBusinessDay": "Y",
            "Account": "54xxxxxx",
            "Ship": {
                "Shipper": {
                    "City": "city",
                    "PostalCode": 123456,
                    "CountryCode": "ID"
                },
                "Recipient" : {
                "City" : "canberra",
                "PostalCode" : 2601,
                "CountryCode" : "AU"
                }
            },
            "Packages": {
                "RequestedPackages": {
                    "@number": "1",
                    "Weight": {
                        "Value": 8.82
                    },
                    "Dimensions": {
                        "Length": 4.33,
                        "Width": 4.33,
                        "Height": 4.33
                    }
                }
            }
        }
    }
}';

$data = json_decode($json, true);

if (isset($data['RateRequest']['RequestedShipment']['DropOffType'])) {

   $data['RateRequest']['RequestedShipment']['DropOffType'] = 'some new value';

}


//... later in your curl call...

 CURLOPT_POSTFIELDS => $data,
