开始从 discuzX3.4 迁移到 nodebb（二）

(续）

3、连接mysql, mongodb传导数据

 **用户数据字段对照表：**

需要用post到API的方式在nodebb批量新建用户，API(v3.65): /api/v3/users，并且需要在后台生成Bearer Token，以下是官方指南：

To create a Bearer Token, do this:

• Settings > API Access > Create Token > Specify your User ID and Description (for example „Linuxfabrik API Token“).

感谢segmentfault网的bay1网友发表的文章，有了前人的努力，再修改一下便可以用起来：

在原来基础上增加一些字段

def get_forum_post(fid, tid):
    forum_post_sql = "select author,dateline,message,authorid from pre2_forum_post where fid=%a and tid=%a" % (
        fid, tid)
    dz_cursor.execute(forum_post_sql)
    forum_post = dz_cursor.fetchall()
    return forum_post

def get_salt(uid):
    salt_sql = "select salt from pre2_ucenter_members where uid=%a" % uid
    dz_cursor.execute(salt_sql)
    salt = dz_cursor.fetchone()["salt"]
    return salt

def get_mobile(uid):
    mobile_sql = "select mobile from pre2_common_member_profile where uid=%a" % uid
    dz_cursor.execute(mobile_sql)
    mobile = dz_cursor.fetchone()["mobile"]
    return mobile

def get_views(uid):
    views_sql = "select views from pre2_common_member_count where uid=%a" % uid
    dz_cursor.execute(views_sql)
    views = dz_cursor.fetchone()["views"]
    return views

def get_threads(uid):
    threads_sql = "select threads from pre2_common_member_count where uid=%a" % uid
    dz_cursor.execute(threads_sql)
    threads = dz_cursor.fetchone()["threads"]
    return threads

def get_posts(uid):
    posts_sql = "select posts from pre2_common_member_count where uid=%a" % uid
    dz_cursor.execute(posts_sql)
    posts = dz_cursor.fetchone()["posts"]
    return posts

def get_realname(uid):
    realname_sql = "select realname from pre2_common_member_profile where uid=%a" % uid
    dz_cursor.execute(realname_sql)
    realname = dz_cursor.fetchone()["realname"]
    return realname

def get_birth_site(uid):
    birth_site_sql = "select birthyear,birthmonth,birthday,site from pre2_common_member_profile where uid=%a" % uid
    dz_cursor.execute(birth_site_sql)
    birth_site = dz_cursor.fetchone()
    return birth_site

def get_resideprovince(uid):   # 所在省份 location
    resideprovince_sql = "select resideprovince from pre2_common_member_profile where uid=%a" % uid
    dz_cursor.execute(resideprovince_sql)
    resideprovince = dz_cursor.fetchone()["resideprovince"]
    return resideprovince    

def get_bio(uid):   # 所在省份 location
    bio_sql = "select bio from pre2_common_member_profile where uid=%a" % uid
    dz_cursor.execute(bio_sql)
    bio = dz_cursor.fetchone()["bio"]
    return bio        

def get_lastvisit(uid):
    lastvisit_sql = "select lastvisit from pre2_common_member_status where uid=%a" % uid
    dz_cursor.execute(lastvisit_sql)
    lastvisit = dz_cursor.fetchone()["lastvisit"]
    return lastvisit

def get_lastpost(uid):
    lastpost_sql = "select lastpost from pre2_common_member_status where uid=%a" % uid
    dz_cursor.execute(lastpost_sql)
    lastpost = dz_cursor.fetchone()["lastpost"]
    return lastpost

经测试生成新用户并把原论坛资料附上去没有多大问题，接下来要处理的就是登录和密码问题，因为discuzX3.4用的是hash也就是

md5(md5(password + salt)) 方式 （注意X3.5是用的bcrypt）

上表看到了我新加了dz_password, salt, mobile字段便是为了解决这方面的问题，上nodebb群向高手请教，大伙认为需要新写一个插件才好处理，并且不会影响日后nodebb的更新。

我代码能力很有限，写插件是头一次，便上网找到一些可能有用的资料：

nodebb接入已有的账号体系

一位nodebb的开发者也写了些指南：
