我在我的中使用SafetyNet reCAPTCHA API，Activity我已将 API 调用分解为以下内容：一个Repository类，一个interface进行POST调用的类，一个data class存储JSON接收到的响应的类ViewModel，一个Success监听器类和Failure监听器类在我的Activity.

Repository：

class RecaptchaRepository {
    fun doRecaptchaValidation(
        @NonNull baseUrl: String,
        @NonNull response: String,
        @NonNull key: String
    ): LiveData<RecaptchaVerifyResponse> {
        val data: MutableLiveData<RecaptchaVerifyResponse> = MutableLiveData()
        val params: MutableMap<String, String> = HashMap()
        params["response"] = response
        params["secret"] = key
        getRecaptchaValidationService(baseUrl).verifyResponse(params)
            .enqueue(object : Callback<RecaptchaVerifyResponse> {
                override fun onResponse(
                    call: Call<RecaptchaVerifyResponse>,
                    response: Response<RecaptchaVerifyResponse>
                ) {
                    data.value = response.body()
                }

                override fun onFailure(call: Call<RecaptchaVerifyResponse>, t: Throwable) {
                    data.value = null
                }

            })
        return data
    }

    private fun getRecaptchaValidationService(@NonNull baseUrl: String): RecaptchaVerificationService {
        return getRetrofit(baseUrl).create(
            RecaptchaVerificationService::class.java
        )
    }

    private fun getRetrofit(@NonNull baseUrl: String): Retrofit {
        val moshi = Moshi.Builder().addLast(KotlinJsonAdapterFactory()).build()
        val client = OkHttpClient.Builder()
            .connectTimeout(60, TimeUnit.SECONDS)
            .writeTimeout(60, TimeUnit.SECONDS)
            .readTimeout(60, TimeUnit.SECONDS)
            .build()
        return Retrofit.Builder()
            .addConverterFactory(MoshiConverterFactory.create(moshi))
            .baseUrl(baseUrl)
            .client(client)
            .build()
    }
}

Interface拨打POST电话：

interface RecaptchaVerificationService {
    @Headers("Content-Type: application/x-www-form-urlencoded; charset=utf-8")
    @POST("/recaptcha/api/siteverify")
    fun verifyResponse(@QueryMap params: Map<String, String>): Call<RecaptchaVerifyResponse>
}

data class生成者Moshi：@JsonClass(generateAdapter = true)

data class RecaptchaVerifyResponse(
    @Json(name = "success")
    val success: Boolean,
    @Json(name = "challenge_ts")
    val challenge_ts: String,
    @Json(name = "apk_package_name")
    val apk_package_name: String,
    @Json(name = "error-codes")
    val error_codes: List<String>
)

ViewModel：

class RecaptchaResponseViewModel(application: Application) : AndroidViewModel(application) {
    fun getmRecaptchaObservable(@NonNull baseUrl: String, @NonNull response: String, @NonNull key: String): LiveData<RecaptchaVerifyResponse> {
        return RecaptchaRepository().doRecaptchaValidation(baseUrl, response, key)
    }
}

我的活动方法中的SafetyNetAPI 调用onCreate：

SafetyNet.getClient(this).verifyWithRecaptcha(BuildConfig.RECAPTCHA_SITE_KEY)
    .addOnSuccessListener(RecaptchaSuccessListener())
    .addOnFailureListener(RecaptchaFailureListener())

还有Success监听器类和Failure监听器类，也在我的Activity：

private inner class RecaptchaSuccessListener : OnSuccessListener<SafetyNetApi.RecaptchaTokenResponse> {
    override fun onSuccess(recaptchaTokenResponse: SafetyNetApi.RecaptchaTokenResponse) {
        val userResponseToken: String = recaptchaTokenResponse.tokenResult!!
        if (userResponseToken.isNotEmpty()) {
            recaptchaViewModel.getmRecaptchaObservable("https://www.google.com", userResponseToken, BuildConfig.RECAPTCHA_SECRET_KEY).observe(this@LoginActivity, object : Observer<RecaptchaVerifyResponse> {
                override fun onChanged(@Nullable recaptchaVerifyResponse: RecaptchaVerifyResponse?) {
                    if (recaptchaVerifyResponse != null && recaptchaVerifyResponse.success) {
                        // reCAPTCHA successfully worked and verified user is human
                    } else {
                        // reCAPTCHA response validation failed
                    }
                }
            })
        }
    }
}

private inner class RecaptchaFailureListener : OnFailureListener {
    override fun onFailure(@NonNull e: Exception) {
        // Device side validation resulted in no token. Failure
    }
}

现在在Success侦听器类的onChanged方法中，当它检查 if recaptchaVerifyResponseis notnull和 if recaptchaVerifyResponse.successistrue时，它会失败，因为success, challenge_ts,apk_package_name和error_codes中的变量data class都设置为null。

为什么会这样？我做错了什么导致所有字段都设置为null？
