@Override
public void onResponse(int what, String response) {
}
@Override
public void onFailure(int what, String error) {

},"ur;",map);
}
或者：
HashMap<String, String> map = new HashMap<>();
//使MainActivity繼承OkHttpManager.HttpCallBack，重寫方法
OkHttpManager.getInstance().postAsynHttp(201,MainActivity.this,"url",map);
@Override
public void onResponse(int what, String response) {
}
@Override
public void onFailure(int what, String error) {
}
