改造2 - 获得200响应但不返回数据

Question

TL; DR

---

新的改造,所以它可能是一个noob错误.端点在邮递员中工作正常,我得到Response{protocol=http/1.1, code=200, message=OK, url=http://192.168.1.249/api/v1/user/1}了响应,但没有与用户相关的数据.

问题

---

我使用Laravel构建了一个REST API,我想从设备访问它.将需要访问许多端点,但我无法使其中的任何端点工作.我想在添加其余部分之前让一个工作,但即使我得到200我没有得到数据.

所有属性都存在于response.body中,但它们都是null.

        cdenAPI = retrofit.create(CdenApi.class);
    }

    Callback<User> userCallback = new Callback<User>() {
        @Override
        public void onResponse(Call<User> call, Response<User> response) {
            if (response.isSuccessful()) {
                User data = new User();
                data = response.body();

端点的JSON:

{
    "msg": "User information",
    "user": {
        "id": 1,
        "name": "Guy",
        "email": "guy@ganker.com",

        "created_at": "2017-08-22 15:53:06",
        "updated_at": "2017-08-22 15:53:06",
        "view_boxes": {
            "href": "api/v1/user/1",
            "method": "GET"
        }
    }
}

我需要知道我哪里出错了.我是新来的改造,所以我确定我已经实现了一些错误,但我看不出问题.

在此先感谢您的帮助.

Answer 1

我认为问题在于你有Call<User>,但至于你的json,你在服务器的响应中得到UserResult,所以相反它必须Call<UserResult>和userCallback相同,而不是

Callback<User> userCallback = new Callback<User>

肯定是

Callback<UserResult> userCallback = new Callback<UserResult>

在响应中也是如此

public void onResponse(Call<UserResult> call, Response<UserResult> response) {
            if (response.isSuccessful()) {
                User data = new User();
                data = response.body().user;
            } else {

            }
        }
