我收到onResponse作为成功消息，但response.tobody为空。

我尝试过的内容如下。

请帮助我。

主要活动

public class MainActivity extends AppCompatActivity {
BreakdownResponse breakdownResponse;
ApiInterface apiInterface;
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    button=(Button)findViewById(R.id.button);

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            signUp();
        }
    });
}



private void signUp() {
    // display a progress dialog
    final ProgressDialog progressDialog = new ProgressDialog(MainActivity.this);
    progressDialog.setCancelable(false); // set cancelable to false
    progressDialog.setMessage("Please Wait"); // set message
    progressDialog.show(); // show progress dialog
    // Call<BreakdownResponse> call = apiInterface.registration(1,"1","1","101010");

    HashMap<String,response> map = new HashMap<>();
    map.put("breakdowncall",new response("1","1","1","101010"));
    Api.getClient().create(ApiInterface.class).registration(map).enqueue(new Callback<BreakdownResponse>() {

您是否尝试过传递参数：

 map.put("Customer", RequestBody.create(MediaType.parse("text/plain"), "1");
 map.put("Zone", RequestBody.create(MediaType.parse("text/plain"), "1");
 map.put("Region", RequestBody.create(MediaType.parse("text/plain"), "1");

并使用PartMap：

  @Multipart
    @POST("breakdowncall")
    Call<ModelTo> callMethod(
            @PartMap() Map<String, RequestBody> input
    );
