android - 改造错误应为 BEGIN_ARRAY 但为 BEGIN_OBJECT

问题描述

我尝试使用手机号码获取 Otp，但它显示这样的错误

E/FAILISJERE：java.lang.IllegalStateException：应为 BEGIN_ARRAY，但在第 1 行第 54 列路径 $.data 处为 BEGIN_OBJECT

这是我的网址：= http://192.168.1.105/XXXX/XXXXX/XXXXXX/default/send-otp

请求字段：手机号，姓名

回应是这样的：-

{
"error": false,
"msg": "Otp sent successfully",
"data": {
    "otp": 152265
}

}

APIClient.Kt:-

object ApiClient {

private var retrofit: Retrofit? = null
val client: Retrofit
    get() {
        if (retrofit == null) {
            retrofit = Retrofit.Builder()
                    .baseUrl(AppConfig.BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build()
        }
        return retrofit!!
    }

}

APIInterface.kt:-

interface ApiInterface {
@FormUrlEncoded
@POST("send-otp")
fun GET_OTP(@Field("name") name: String, @Field("mobileNo") mobileNo: String): Call<OTPSendResponse>

}

AppConfig.kt：-

class AppConfig {
companion object {
    const val BASE_URL = "http://192.168.1.105/XXXX/XXXXX/XXXXX/default/"
}

}

OtpModel.kt:-

class OtpModel {
constructor(otp: Int) {
    this.otp = otp
}
@SerializedName("otp")
var otp: Int = 0

}

OtpSendResponse.kt:-

class OTPSendResponse {

constructor(error: String, data: ArrayList<OtpModel>, msg: String) {
    this.error = error
    this.data = data
    this.msg = msg
}
@SerializedName("error")
var error: String = ""

@SerializedName("msg")
var msg: String = ""

@SerializedName("data")
var data: ArrayList<OtpModel> = ArrayList()

}

MyActivity.kt:-

private fun sendNameAndMobileNum(name: String, mobileNum: String) {
    Log.e("MOBILE", "${mobileNum}")
    val apiService = ApiClient.client.create(ApiInterface::class.java)

    val call = apiService.GET_OTP(name, mobileNum)

    call.enqueue(object : Callback<OTPSendResponse> {

        override fun onResponse(call: Call<OTPSendResponse>, response: Response<OTPSendResponse>) {
            Log.e("OTP", "${response.body()?.data!![0].otp}")

            val otpIs = response.body()!!.data[0].otp
            val i = Intent(this@AddNumActivity, OTPVerifyActivity::class.java)
            i.putExtra("otp", otpIs)
            i.putExtra("mobileNum", mobileNum)
            startActivity(i)
        }

        override fun onFailure(call: Call<OTPSendResponse>, t: Throwable) {
            Toast.makeText(this@AddNumActivity, "Ooops !!", Toast.LENGTH_SHORT).show()

            Log.e("FAILISJERE", "${t.message}")
        }
    })
}

解决方案

更改模型类，因为在 json 响应中没有任何数组，因此删除 ArrayList 标记

data: ArrayList<OtpModel>

至

data: OtpModel

因为它不是数组
