使用 Moshi 将 JSON 阵列发布到 RetroFit 2

Question

I need to send my request parameters to the Retrofit 2 API call. My request packet should be sent as followed:

REQUEST PACKET:
{
    "msgLang": "EN",
    "recieverMsisdn": [
        {
            "msisdn": "1234"
        },
        {
            "msisdn": "5678"
        }
    ],
    "textmsg": "Hello World",
    "senderName": "333111222",
    "orderKey": "orderSent"
}

I am using kotlin and retrofit for the POST request as:

val sendBulkSMSRequest = SendBulkSMSRequest(
            selectedLanguageKey,
            jsonArrayOfSelectedUsers,
            bulkSMSMessage,
            picMsisdn,
            ConstantsUtility.OrderManagementKeys.BULK_SMS
        )

        var mObserver = mUsersSelectionRepository.requestSendBulkSMS(sendBulkSMSRequest)
        mObserver = mObserver.onErrorReturn { null }

        disposable = mObserver
            .compose(applyIOSchedulers())
            .subscribe(
                { result ->
                    view()?.hideLoading()
                    view()?.isShowErrorPopup(result)?.let {
                        if (!it) {
                            sendBulkSMSResponseLiveData.postValue(result)
                        }
                    }
                },
                { error ->
                    view()?.hideLoading()
                    view()?.loadError(error)
                })

        compositeDisposables!!.add(disposable)

I just want to post the request packet that is composed of some strings and an JSONArray. So far this code compiles but the API call throws error without any description or details. For the Request Class, I am doing this like:

data class SendBulkSMSRequest(
    @Json(name = "msgLang")
    val msgLang: String? = null,

    @Json(name = "recieverMsisdn")
    val recieverMsisdn: JSONArray? = null,

    @Json(name = "textmsg")
    val textmsg: String? = null,

    @Json(name = "senderName")
    val senderName: String? = null,

    @Json(name = "orderKey")
    val orderKey: String? = null
)

You should try like this:

REQUEST PACKET:
{
    "msgLang": "EN",
    "recieverMsisdn": [
        "1234",
        "5678"
    ],
    "textmsg": "Hello World",
    "senderName": "333111222",
    "orderKey": "orderSent"
}

And your model should be

data class SendBulkSMSRequest(
    @Json(name = "msgLang")
    val msgLang: String? = null,

    @Json(name = "recieverMsisdn")
    val recieverMsisdn: List<String>? = null,

    @Json(name = "textmsg")
    val textmsg: String? = null,

    @Json(name = "senderName")
    val senderName: String? = null,

    @Json(name = "orderKey")
    val orderKey: String? = null
)

Or if you need to stick with your REQUEST PACKET, then try:

data class SendBulkSMSRequest(
    @Json(name = "msgLang")
    val msgLang: String? = null,

    @Json(name = "recieverMsisdn")
    val recieverMsisdn: List<Msisdn>? = null,

    @Json(name = "textmsg")
    val textmsg: String? = null,

    @Json(name = "senderName")
    val senderName: String? = null,

    @Json(name = "orderKey")
    val orderKey: String? = null
)

and create Msisdn data model

data class Msisdn(
    @Json(name = "msisdn")
    val msisdn: String? = null
)
