Question

我需要帮助从json对象数据存储acces_token和token_type，这样我可以让用户sesion工作，每次用户登录时，都会对一个新令牌进行签名，我希望我的acctivity与令牌同步，当令牌终止（过期）时，用户返回登录，到目前为止我只通过“String _token_type”中的某个字符串进行sesion管理=“token_type”;“到目前为止，这是一个糟糕的结果，我还需要以某种方式将令牌和令牌类型发布到其他活动以通过用户令牌解析JsonObject，我真的很抱歉我的英语不好，也许是一个愚蠢的问题，我是真的很绝望，我试着弄清楚它3天

您应该使用Google Gson。

首先创建两个模型类，一个用于Session Response，另一个用于数据对象。做如下： 1.创建模型。确保每个类都完全模仿响应键。另外，请确保每个类都有一个默认构造函数。

public class SessionResponse {

  int code;
  String error, message;
  Data data;

  public SessionResponse(){}

  public int getCode() {
      return code;
  }

  public void setCode(int code) {
      this.code = code;
  }

  public String getError() {
      return error;
  }

  public void setError(String error) {
      this.error = error;
  }

  public String getMessage() {
      return message;
  }

  public void setMessage(String message) {
      this.message = message;
  }

  public Data getData() {
      return data;
  }

  public void setData(Data data) {
      this.data = data;
  }
}

public class Data {

    String access_token, token_type;
    int expires_in;

    public Data(){}

    public String getAccess_token() {
        return access_token;
    }

    public void setAccess_token(String access_token) {
        this.access_token = access_token;
    }

    public String getToken_type() {
        return token_type;
    }

    public void setToken_type(String token_type) {
        this.token_type = token_type;
    }

    public int getExpires_in() {
        return expires_in;
    }

    public void setExpires_in(int expires_in) {
        this.expires_in = expires_in;
    }

}

然后使用Google Gson支持库将Json转换为对象。然后，您可以将其存储到共享首选项，并从任何活动中获取它。或者甚至通过Intent将它传递给一个活动。

Gson gson = new Gson();

//get the class from JSON
SessionResponse response = gson.fromJson(jsonResponseString, SessionResponse.class);

//convert to String
String jsonResponse = gson.toJson(response);

我希望这是一个好的开始！
