Question

我有一个带有mongo，express和node的服务器我试图通过用户名获取用户数据： myip/users/name/example_name

其中example_name是参数。

这是我的代码：

主要活动：

@BindView(R.id.btnTest)
Button btnTest;
@BindView(R.id.tvTest)
TextView tvTest;

@OnClick(R.id.btnTest) void changeText(){
    GitHubService gitHubService = GitHubService.retrofit.create(GitHubService.class);
    final Call<User> call =
            gitHubService.getUser("dolev");

    call.enqueue(new Callback<User>() {
        @Override
        public void onResponse(Call<User> call, Response<User> response) {
            Toast.makeText(MainActivity.this,"This: " +  response.body().getName(), Toast.LENGTH_SHORT).show();
            tvTest.setText("response success," + response.body().toString());
        }
        @Override
        public void onFailure(Call<User> call, Throwable t) {
            tvTest.setText("Something went wrong: " + t.getMessage());
        }
    });
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(this);

}

@Override
public void onResponse(Call<User> call, Response<User> response) {
    int code = response.code();
    if (code == 200) {
        User user = response.body();
        Log.v("FETCH", response.body().getEmail());
        Toast.makeText(this, "Got the user: " + user.getName(), Toast.LENGTH_LONG).show();
    } else {
        Toast.makeText(this, "Did not work: " + String.valueOf(code), Toast.LENGTH_LONG).show();
    }
}

@Override
public void onFailure(Call<User> call, Throwable t) {
    Toast.makeText(this, "Nope", Toast.LENGTH_LONG).show();

}

GitHubService：

public interface GitHubService {



@GET("users/name/{username}")
Call<User> getUser(@Path("username") String username);

@GET("users}")
Call<List<User>> getAllUsers();





public static final Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(Global.API)
        .addConverterFactory(GsonConverterFactory.create())
        .build();

}

当我试图获取JSON数据时 - 响应正文为空 - 例如名称，ID，电子邮件等。 response.body（）。toString（）给我一个结果： @ 59285 数量变化.. 我的意思是，我得到身体 com.noy.photobomb.model.User@84593 虽然@后面的数字改变了每个按钮的点击次数。我从早上开始研究它，我搜索了StackOverFlow的许多教程和错误，但我还没有发现这样的错误。有人可以帮助我吗？

Answer 1

@Sagar Jogadia 通过聊天帮我解决了问题。问题是数据是在JSON数组中，我试图获取一个对象，因此用户I而不是User用户列表。我通过正文得到了数据，然后是一个带有一个索引的数组 - response.body.get（0）.getName（） - 例如。非常感谢你

无法获取Retrofit 2响应体
