Question

我正在尝试实现一个请求，我可以使用Retrofit同时发送多个请求，因此，我创建了一个这样的接口：

@FormUrlEncoded
@POST("/locations/add.json")
void sendMultipleLocations(@Query("token")String token, @FieldMap List<Map<String, String>> multipleLocations, Callback<String> callback);

然后，我在List中构建地图数据，然后推送。

private void sendLocations(List<Map<String, String>> multipleLocations) {
    RestClient.get(this).sendMultipleLocations("token", multipleLocations, new Callback<String>() {
        @Override
        public void success(String s, Response response) {
            Log.e("MultipleLocationResp", s);
        }

        @Override
        public void failure(RetrofitError error) {
            error.printStackTrace();
        }
    });
}

我一直收到这个错误：

 java.lang.IllegalArgumentException: PodApi.sendMultipleLocations: @FieldMap parameter type must be Map. (parameter #2)

Answer 1

您必须使用地图，而不是地图列表。 @FieldMap Map<String, String> multipleLocations。

改造@FieldMap参数类型必须是Map
