java - 用于 Retrofit2 回调的 JSON 中的 POJO 类

Question

{
   "success":true,
   "userobject":{
       "username":"user",
       "email":"user@gmail.com",
       "password":"user123"
    }
}

这是我的 JSON。我想由此创建 POJO 类。现在我有这样的东西:

public class LoginResponse
{
    @SerializedName("success")
    @Expose
    private Boolean success;

    @SerializedName("username")
    @Expose
    private String username;

    @SerializedName("email")
    @Expose
    private String email;

    @SerializedName("password")
    @Expose
    private String password;

    public Boolean getSuccess() {
        return success;
    }

    public String getUsername() {
        return username;
    }

    public String getEmail() {
        return email;
    }

    public String getPassword() {
        return password;
    }
}

我想访问 Retrofit 回调中的“用户名”、“电子邮件”、“密码”等字段:

 final LoginRequest loginRequest = new LoginRequest(email, password);
        Call<LoginResponse> call = service.login(loginRequest);

        call.enqueue(new Callback<LoginResponse>() {
            @Override
            public void onResponse(Call<LoginResponse> call, Response<LoginResponse> response)
            {
                if(response.isSuccessful()) {
                    background.setImageResource(R.drawable.bg_login_screen);
                    progressBar.setVisibility(View.GONE);

                    Toast.makeText(LoginActivity.this, response.body().getEmail(), Toast.LENGTH_SHORT).show();
                }

而且它不起作用。我当然只能访问“成功”字段。 POJO 类应该是什么样子？

Answer 1

userObject 是一个新对象，您应该创建一个新类来访问它:

public class LoginResponse {
    @SerializedName("success")
    @Expose
    private Boolean success;

    private UserObject userobject;


    public Boolean getSuccess() {
        return success;
    }

    public UserObject getUserObject() {
       return userobject;
    }
}

还有

public class UserObject {
    @SerializedName("username")
    @Expose
    private String username;

    @SerializedName("email")
    @Expose
    private String email;

    @SerializedName("password")
    @Expose
    private String password;

    public String getUsername() {
        return username;
    }

    public String getEmail() {
        return email;
    }

    public String getPassword() {
        return password;
    }
}
