如何使用GET调用在Android改造中发送/解析我下面的json数据

Question

public interface iMakeType {
    @Headers({"Content-Type:application/json"})
    @GET("/getmaptable?map_type=Model&brand=(here i need to pass my value dynamically)")
    MakeResponse getMakeTypeData(@Query("map_type")String map_type);
}

how can i send my brand value to above call dynamically

getmaptable?map_type=Model&brand=BMW

Answer 1

Use this:

public interface iMakeType {
    @Headers({"Content-Type:application/json"})
    @GET("/getmaptable")
    MakeResponse getMakeTypeData(@Query("map_type") String map_type, @Query("brand") String brand);
}

Then:

yourApi.getMakeTypeData("Model", "BMW").enqueue(...)

Answer 2

you can take advantage of @QueryMap from retrofit.

- The @QueryMap annotation expects a Map with key-value-pairs of type String . Each key which has a non-null value will be mapped and you can dynamically add your desired query parameters.

public interface iMakeType {
    @Headers({"Content-Type:application/json"})
    @GET("/getmaptable")
    MakeResponse getMakeTypeData(@QueryMap Map<String, String> map);
}

and implement it like below-

 private MakeResponse makeType() {  
    Map<String, String> data = new HashMap<>();
    data.put("map_type", "Model");
    data.put("brand", "BMW");


    MakeResponse call = api.getMakeTypeData(data);
    call.enqueue(…);

}

I hope, this will help you to add @Query Param Dynamically !
