如何使用通过 Retrofit Kotlin 编码的表单 URL 发送对象数组？

Question

我想将表单 URL 编码发送到服务器，但参数需要对象数组

我尝试过使用 Retrofit 的 FieldMap 并传递数据，但是当我尝试使用 Postman 时得到不同的响应

参数需要传递

{
  "allowedStatus": "submit",
  "filters": [
    {
      "userId": "2"
    }
  ],
  "page": 1,
  "pageSize": 2
}

改造

@FormUrlEncoded
    @POST("ticket/status-list")
    fun getTicketStatusList(
        @Field("allowedStatus") allowedStatus: String,
        @FieldMap filters: HashMap<String, String>,
        @Field("page") page: Int,
        @Field("pageSize") pageSize: Int
    ): Observable<Response<TicketListModel>>

哈希映射

val filters = HashMap<String, String>()
        filters["userId"] = "1"
        Log.e("fieldMap", filters.toString())
        getTicketStatusList("monitoring", filters, 1, 5)

结果我得到 {}，响应为 200

Answer 1

试试下面的方法：

data class Filters(var userId: String = "")

data class MyRequest(

        var allowedStatus: String = "",
        var filters: ArrayList<Filters>? = null,
        var page: Int = 0,
        var pageSize: Int = 0

        )

@POST("ticket/status-list")
fun getTicketStatusList(@Body request: MyRequest): Observable<Response<TicketListModel>>

Answer 2

请尝试这样：

val filters = HashMap<String, RequestBody>()
filters.put("userId", toRequestBody("2"))
getTicketStatusList("monitoring", filters, 1, 5)

还将“String”的哈希图更改为“RequestBody”

@FormUrlEncoded
    @POST("ticket/status-list")
    fun getTicketStatusList(
        @Field("allowedStatus") allowedStatus: String,
        @FieldMap filters: HashMap<String, RequestBody>,
        @Field("page") page: Int,
        @Field("pageSize") pageSize: Int
    ): Observable<Response<TicketListModel>>

下面的方法将String转换为RequestBody

fun toRequestBody(value: String): RequestBody {
        return RequestBody.create(MediaType.parse("text/plain"), value)
}
