二 用户注册与登陆

1.注册

============================================handlers.py@get('/register')def register():    return {        '__template__': 'register.html'    }============================================register.html$form.postJSON('/api/users', {                    name: this.name.trim(),                    email: email,                    passwd: CryptoJS.SHA1(email + ':' + this.password1).toString()============================================handlers.py                 @post('/api/users')def api_register_user(*, email, name, passwd):    if not name or not name.strip():        raise APIValueError('name')    if not email or not _RE_EMAIL.match(email):        raise APIValueError('email')    if not passwd or not _RE_SHA1.match(passwd):        raise APIValueError('passwd')    users = yield from User.findAll('email=?', [email])    if len(users) > 0:        raise APIError('register:failed', 'email', 'Email is already in use.')    uid = next_id()    sha1_passwd = '%s:%s' % (uid, passwd)    user = User(id=uid, name=name.strip(), email=email, passwd=hashlib.sha1(sha1_passwd.encode('utf-8')).hexdigest(), image='http://www.gravatar.com/avatar/%s?d=mm&s=120' % hashlib.md5(email.encode('utf-8')).hexdigest())    yield from user.save()    # make session cookie:    r = web.Response()    r.set_cookie(COOKIE_NAME, user2cookie(user, 86400), max_age=86400, httponly=True)    user.passwd = '******'    r.content_type = 'application/json'    r.body = json.dumps(user, ensure_ascii=False).encode('utf-8')    return r

2.登陆

============================================handlers.py @get('/signin')def signin():    return {        '__template__': 'signin.html'    }============================================signin.html    $form.postJSON('/api/authenticate', data, function(err, result) {        if (! err) {            location.assign('/');        }============================================handlers.py @post('/api/authenticate')def authenticate(*, email, passwd):    if not email:        raise APIValueError('email', 'Invalid email.')    if not passwd:        raise APIValueError('passwd', 'Invalid password.')    users = yield from User.findAll('email=?', [email])    if len(users) == 0:        raise APIValueError('email', 'Email not exist.')    user = users[0]    # check passwd:    sha1 = hashlib.sha1()    sha1.update(user.id.encode('utf-8'))    sha1.update(b':')    sha1.update(passwd.encode('utf-8'))    if user.passwd != sha1.hexdigest():        raise APIValueError('passwd', 'Invalid password.')    # authenticate ok, set cookie:    r = web.Response()    r.set_cookie(COOKIE_NAME, user2cookie(user, 86400), max_age=86400, httponly=True)    user.passwd = '******'    r.content_type = 'application/json'    r.body = json.dumps(user, ensure_ascii=False).encode('utf-8')    return r
