如何保存会话标识符并在访问服务器时发送？

Question

要维护会话，我必须使用会话 ID。如何保存会话标识符并在每次访问服务器时发送？

我在 header 中获取会话标识符。这是来自 Fiddler 的服务器的响应：

设置 Cookie：JSESSIONID=b09aa2c816d1b；

Class 用于生成接口：

public class NetworkService {
private static final String BASE_URL = "http://";
private static NetworkService mInstance;
private Retrofit mRetrofit;

private NetworkService() {
    mRetrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .build();
}
public static NetworkService getInstance() {
    if (mInstance == null) {
        mInstance = new NetworkService();
    }
    return mInstance;
}
public ApiInterface service() {
    return mRetrofit.create(ApiInterface.class);
}
}

Api:

public interface ApiInterface {
@POST("Register?app=WebAPI")
Call<RegResponse> registration(@Query("phone") String phone);
}

使用：

NetworkService.getInstance()
.service()
.registration(phone)                
.enqueue(new Callback<RegResponse>() {
@Override
    public void onResponse(Call<RegResponse> call, Response<RegResponse>response) {

    }
@Override
public void onFailure(Call<RegResponse> call, Throwable t) {
}
});

有人可以帮我解决这个问题吗？？

要在本地设备中保存会话 ID，请使用共享首选项，这是用于保存和检索会话 ID 的共享首选项。



import android.content.Context;
import android.content.SharedPreferences;

public class SharedPrefManager {

    private static final String PREF_NAME = "AndroidHivePref";
    SharedPreferences pref;

    // Editor for Shared preferences
    SharedPreferences.Editor editor;

    // Context
    Context _context;
    // Shared pref mode
    int PRIVATE_MODE = 0;


    public SharedPrefManager(Context context){
        this._context = context;
        pref = _context.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
        editor = pref.edit();
    }

    public void savesession(String sessionid){
        editor.putString("SESSION_ID",session);
        editor.commit();
    }

   public String getsessionid(){
          String sessionid = pref.getString("SESSION_ID", null);
          return sessionid;
   }


}

用法


//To save Sessionid from onResponse method
...
@Override
    public void onResponse(Call<RegResponse> call, Response<RegResponse>response) {
          // Get sessionid from response object.

          ...
          SharedPrefManager manager = new SharedPrefManager(getApplicationContext());
           //Context object is require to create its object.

          ...
         manager.savesessionid(sessionid);//sessionid is string object got from response above

    }
  ....


// When you want to send sessionid to server either in request data or in request header, get sessionid string object from SharedPrefManager and append it to request object.


SharedPrefManager manager = new SharedPrefManager(getApplicationContext());

String sessionid = manager.getsessionid();
