类型推断失败.预期的类型不匹配

Question

下面的代码显示了错误。类型推断失败。所需类型不匹配需要：找到了Response<BaseResponse<Any>>!:Response<BaseResponse<RetriveUserInfoResponse>!>!

`when`( mockIOnboardingService.validateCustomerIdentity(customerType.toLowerCase(), ValidateCustomerRequest(customerId, documentType, "243546", tyc)))
.thenReturn(Response.success(BaseResponse(payload = RetriveUserInfoResponse("[phone]")))) //--> Here the error

这是validateCustomerIdentity方法

@POST(ApiConstants.bffOnboardingPath + ApiConstants.pathRetriveUserInfo)
suspend fun validateCustomerIdentity(
@Header(ApiConstants.headerXflowService) customerType : String,
@Body body: ValidateCustomerRequest
): Response<BaseResponse<Any>>

如您所见，它返回BaseResponse<Any>。为什么Android Studio将BaseResponse<RetriveUserInfoResponse>!显示为错误

这是RetrieveUserInfoResponse数据类

data class RetriveUserInfoResponse(
@SerializedName("phone")
val phone: String
)

Answer 1

这个问题是Response.success(BaseResponse(payload = RetriveUserInfoResponse("[phone]")))生成的Response<BaseResponse<RetriveUserInfoResponse>>与Response<BaseResponse<Any>>的类型(或子类型(不同。

您可以通过将RetriveUserInfoResponse强制转换为Any:来修复它

Response.success(BaseResponse(payload = RetriveUserInfoResponse("[phone]") as Any))

或者，通过将validateCustomerIdentity()的返回类型更改为Response<out BaseResponse<out Any>>，这是有效的，因为Response<BaseResponse<RetriveUserInfoResponse>>是Response<out BaseResponse<out Any>>:的子类

@POST(ApiConstants.bffOnboardingPath + ApiConstants.pathRetriveUserInfo)
suspend fun validateCustomerIdentity(
@Header(ApiConstants.headerXflowService) customerType : String,
@Body body: ValidateCustomerRequest
): Response<out BaseResponse<out Any>>
