ApiInterface,.kt

@Multipart
@POST("customer")
fun updateCustomerDetail(@PartMap map: Map<String,RequestBody >): Call<UpdateCustomer>

Gradle文件

implementation "com.squareup.okhttp3:okhttp:3.8.1"
implementation "com.squareup.okhttp3:logging-interceptor:3.8.1"
implementation ("com.squareup.retrofit2:retrofit:2.3.0"){
     exclude module: 'okhttp'
}
implementation "com.squareup.retrofit2:converter-gson:2.3.0"

Answer 1

@JvmSuppressWildcards之前添加RequestBody

fun updateCustomerDetail(@PartMap map: Map<String, @JvmSuppressWildcards RequestBody >): Call<UpdateCustomer>

Answer 2

使用HashMap或MutableMap代替Map <K，out V>作为PartMap

另一种对我有效的方法。tpom6oh在Retrofi Kotlin问题中提到

我认为这是因为Map声明是公共接口Map <K，out V>，而out字使值类型通用。您可以尝试改用MutableMap或HashMap。

@Multipart
@POST("customer")
fun updateCustomerDetail(@PartMap map: HashMap<String, RequestBody>): Call<UpdateCustomer>
