【中文标题】SQLite 不保存 JSON 令牌【英文标题】：SQLite Not Saving JSON Token 【发布时间】：2018-04-26 06:19:03 【问题描述】：我有一个 DBHelper 类，并且我保存了来自用户的信息。我还想从服务器保存用户的令牌，但 logcat 中显示错误。请查看我的代码并指出我的错误。
我的 DBHelper 类：
public class DBHelper
private static final String DATABASE_NAME = "tingUser.db";
private static final int DATABASE_VERSION = 1;
private static final String TABLE_NAME = "profileInfo";
private static final String IMAGES_TABLE = "userImage";
private static final String COL_ID = "databaseId";
public static final String COL_USER_ID = "userId";
public static final String COL_FULL_NAME = "fullName";
public static final String COL_GENDER = "gender";
public static final String COL_DOB = "DOB";
public static final String COL_MOBILE_NUM = "mobileNum";
public static final String COL_OCCUPATION = "occupation";
public static final String COL_ORGANIZATION = "organization";
public static final String COL_TOKEN = "JWT Token";
private static final String COL_PROFILE_PHOTO = "profilePhoto";
private Context mCtx;
private DatabaseManager databaseManager;
private SQLiteDatabase db;
public DBHelper(Context context)
this.mCtx = context;
databaseManager = new DatabaseManager(mCtx);
public DBHelper open() throws SQLException
db = databaseManager.getWritableDatabase();
return this;
public void close()
databaseManager.close();
public boolean saveInputField(TingTingUser user)
SQLiteDatabase userDb = databaseManager.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(COL_FULL_NAME, user.getDisplayName());
values.put(COL_USER_ID, user.getUserId());
values.put(COL_GENDER, user.getGender());
values.put(COL_DOB, user.getDob());
values.put(COL_MOBILE_NUM, user.getMobileNumber());
values.put(COL_ORGANIZATION, user.getOrganization());
values.put(COL_OCCUPATION, user.getOccupation());
values.put(COL_TOKEN, user.getJWT_token());
Log.d("database",values.toString());
//values.put(COL_TOKEN, (user.getJWT_token() != null) ? user.getJWT_token() : null);
long result = userDb.insert(TABLE_NAME, null, values); // error occurs here
userDb.close();
if (result == -1)
return false;
else
return true;
public TingTingUser getCurrentUser(int id)
SQLiteDatabase currDB = databaseManager.getWritableDatabase();
Cursor cursor = currDB.query(true, TABLE_NAME, new String[]COL_ID, COL_USER_ID, COL_FULL_NAME, COL_GENDER, COL_DOB, COL_MOBILE_NUM, COL_OCCUPATION, COL_ORGANIZATION, COL_ID + "=?", new String[]String.valueOf(id), null, null, null, null);
if (cursor != null && cursor.moveToFirst())
TingTingUser user = new TingTingUser(Integer.parseInt(cursor.getString(0)), cursor.getString(1), cursor.getString(2), cursor.getString(3), cursor.getString(4), cursor.getString(5), cursor.getString(6), cursor.getString(7) );
return user;
return null;
public void saveCameraImage(byte[] imageBytes)
SQLiteDatabase camDb = databaseManager.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(COL_PROFILE_PHOTO, imageBytes);
camDb.insert(IMAGES_TABLE, null, contentValues);
public void saveGalleryImage(byte[] imageBytes)
ContentValues contentValues = new ContentValues();
contentValues.put(COL_PROFILE_PHOTO, imageBytes);
db.insert(IMAGES_TABLE, null, contentValues);
public byte[] getImage()
Cursor cursor = db.query(true, IMAGES_TABLE, new String[]COL_PROFILE_PHOTO,, null, null, null, null, COL_ID + " DESC", "1");
if (cursor.moveToFirst())
byte[] blob = cursor.getBlob(cursor.getColumnIndex(COL_PROFILE_PHOTO));
cursor.close();
return blob;
cursor.close();
Toast.makeText(mCtx, "No Image Found", Toast.LENGTH_SHORT).show();
return null;
public class DatabaseManager extends SQLiteOpenHelper
public DatabaseManager(Context context)
super(context, DATABASE_NAME, null, DATABASE_VERSION);
@Override
public void onCreate(SQLiteDatabase sqLiteDatabase)
String db_create = " Create Table " + TABLE_NAME + " ("
+ COL_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ COL_USER_ID + " TEXT, "
+ COL_FULL_NAME + " TEXT, "
+ COL_GENDER + " TEXT, "
+ COL_DOB + " TEXT, "
+ COL_MOBILE_NUM + " TEXT, "
+ COL_OCCUPATION + " TEXT, "
+ COL_ORGANIZATION + " TEXT "
+ COL_TOKEN + " TEXT VARCHAR 1024) ";
sqLiteDatabase.execSQL(db_create);
String img_create = "Create table " + IMAGES_TABLE + " ("
+ COL_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ COL_PROFILE_PHOTO + " BLOB NOT NULL )";
sqLiteDatabase.execSQL(img_create);
@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1)
sqLiteDatabase.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
onCreate(sqLiteDatabase);
sqLiteDatabase.execSQL("DROP TABLE IF EXISTS " + IMAGES_TABLE);
onCreate(sqLiteDatabase);
在我的活动中，除了令牌之外的其他字段正在保存。我调用了辅助方法来保存令牌，如下所示：
JsonObjectRequest otpObjectRequest = new JsonObjectRequest(Request.Method.POST, Constants.TING_VERIFY_OTP_ENDPOINT, verifyOTPObject, new Response.Listener<JSONObject>()
@Override
public void onResponse(JSONObject response)
Log.d("OTPDialogFragment", "OTP Verification Response is: \t" + response.toString());
Log.d("OTPDialogFragment", "OTP Verified Successfully");
try
JSONObject verifyObject = new JSONObject(response.toString());
JSONObject userObject = verifyObject.getJSONObject("user");
userId = userObject.getString("_id");
Log.d(TAG, "Retrieved user id is:\t" + userId);
userToken = verifyObject.getString("token"); // getting user token from server correctly
Log.d("jwt token", userToken);
TingTingUser user = new TingTingUser();
user.setDisplayName(fullName);
user.setMobileNumber(num);
user.setGender(genderVal);
user.setDob(dob);
user.setOccupation("default");
user.setOrganization("default");
user.setUserId(userId);
user.setJWT_token(userToken); // saving in model class
if (!TextUtils.isEmpty(fullName) && !TextUtils.isEmpty(genderVal) && !TextUtils.isEmpty(dob) && !TextUtils.isEmpty(userId) && !userToken.isEmpty())
if (dbHelper.saveInputField(user) == true) // saving model object in db and error occurs here
Toast.makeText(getContext(), "Saved User", Toast.LENGTH_SHORT).show();
else
Toast.makeText(getContext(), "Save Failed", Toast.LENGTH_SHORT).show();
logcat 中的错误：

它在我的 create table 语句中显示语法错误，但我觉得一切正常。请指出我的错误。谢谢。
【问题讨论】：
【参考方案1】：应该是：
INSERT INTO profileInfo(JWT_token,fullName,userId,occupation,gender,DOB,mobileNum,organization) VALUES (?,?,?,?,?,?,?,?)
变量中不能有空格。
【讨论】：
我应该在哪里添加“”在 dbhelper 类或注册中？ @AnandRajput 我改变了答案，尝试从变量中删除空间以上是关于SQLite 不保存 JSON 令牌的主要内容，如果未能解决你的问题，请参考以下文章
