请帮帮我…我是新手…您的com.dgdev.mtmicds.DbAccess.Remote.UserRegistrationModel为空。通过进入调试模式检查是否分配了任何值。在调试模式下一步一步地运行代码,并检查它是如何初始化的 提示:在调试器中检查这一行代码:
UserRegistrationModel res = response.body();
试试这个
@Override
public void onResponse(Call<UserRegistrationModel> call, Response<UserRegistrationModel> response) {
if(response.isSuccessful()) {
UserRegistrationModel res = response.body();
if(res!=null) {
Toast.makeText(view.getContext(), res.getStatus(), Toast.LENGTH_LONG).show();
} else {
Toast.makeText(view.getContext(), "Didn't get response", Toast.LENGTH_LONG).show();
}
}
}
@覆盖
公共void onResponse(调用、响应){
if(response.issusccessful()){
UserRegistrationModel res=response.body();
如果(res!=null){
Toast.makeText(view.getContext()、res.getStatus()、Toast.LENGTH_LONG.show();
}否则{
Toast.makeText(view.getContext(),“未得到响应”,Toast.LENGTH_LONG.show();
}
}
}
您可能希望检查您是否收到正确的响应我收到来自服务器的json响应{“status”:“ok”,“answer”:“User Registered!”}请检查状态您是否收到了作为500的响应代码(内部服务器错误)。请在邮递员的帮助下检查。请也把你的模型课放在这里?
