When I'm trying to get the JSON data- the response body is null - eg the name, id, email etc.. The response.body().toString() gives me a result of : @59285 And the number changes.. I mean, I get as the body class com.noy.photobomb.model.User@84593 While the number after the @ changes every button click. 当我尝试获取JSON数据时-响应主体为空-例如名称,ID,电子邮件等。response.body()。toString()给我的结果是:@ 59285并且数字更改。我的意思是,我得到的是主体类com.noy.photobomb.model.User@84593 @之后的数字会更改每个按钮的单击。 I am working on it since the morning and I have searched through many tutorials and errors of StackOverFlow but I haven't found such error.
从早上开始,我就在研究它,我搜索了许多教程和StackOverFlow的错误,但没有发现此类错误。 Can someone please help me?
有人可以帮帮我吗?
@Sagar Jogadia Helped me through the chat to figure it out. @Sagar Jogadia帮助我完成了聊天过程,以解决问题。 The problem was that the data was in JSON Array and I tried to fetch an object, so instead of User I user a list of users.
问题在于数据位于JSON数组中,我试图获取一个对象,因此我使用用户列表代替了User。 I got the data through the body which then was an array with one index - response.body.get(0).getName() - for example.
我通过主体获取数据,该主体然后是具有一个索引的数组-例如,response.body.get(0).getName()。 Thank you very much
非常感谢你
