需要帮助使用Mule将两个Json结果合并为单个响应吗

有两个http调用（调用RESTAPI），它们给出两个不同的响应。 第一个是为下面这样的商店提供json响应

    {
    "shops": [
        {
            "shop": {
                "code": "a",
                "streetName": "a",
                "city": "a",
                "district": "a",
                "state": "a",
                "postalCode": "a",
                "country": "a"

            }
        },
        {
            "shop": {
                "code": "b",
                "streetName": "b",
                "city": "b",
                "district": "b",
                "state": "b",
                "postalCode": "b",
                "country": "b"
            }
        }
    ]
}

另一个调用是为给定的代码给销售办事处（代码与商店的代码相同）。它为给定的代码返回单个销售办事处

    {
    "salesOffice": {
        "shop": {
            "code": "a"
        },
        "office": "a",
        "branch": "a",
        "district": "a",
        "subRegion": "a",
        "region": "a"
    }
}

我的要求是获取shops，它是一个json数组，为每个shop添加sales office，并返回一个json响应，如下所示

 {
    "shops": [
        {
            "shop": {
                "code": "a",
                "streetName": "a",
                "city": "a",
                "district": "a",
                "state": "a",
                "postalCode": "a",
                "country": "a",
                "salesOffice": {
                    "office": "a",
                    "branch": "a",
                    "district": "a",
                    "subRegion": "a",
                    "region": "a"
                }
            }
        },
        {
            "shop": {
                "code": "b",
                "streetName": "b",
                "city": "b",
                "district": "b",
                "state": "b",
                "postalCode": "b",
                "country": "b",
                "salesOffice": {
                    "office": "b",
                    "branch": "b",
                    "district": "b",
                    "subRegion": "",
                    "region": "b"
                }
            }
        }
    ]
}

有没有办法达到这个结果

编辑

我需要得到两个商店的销售办公室（每个商店代码都会有一个http请求），并将其合并到响应中。所以，如果我得到两个商店，那么我需要发送两个http请求，以获取salesoffice中的这些代码，然后将其与响应合并

---

因此，第一个电话将给我商店（让我们说两个商店）。然后我需要通过在每个商店中获取“代码”来进行两次http调用，以获得销售办事处，然后我需要将两个商店与各自的销售办事处合并。

您可以执行类似的操作。我使用dataweave转换json

模拟API响应是对API的http调用
