之前用小程序做項目，因為后臺使用的java開發，一切順利，但切換成django做RESTful API接口時，在登陸注冊時一直出現問題，網上搜索，借助一個網友的回答，找到了一種可行的解決方案，現記錄如下。

具體流程

django的用戶權限認證

django有一套自己的完善用戶模型，由于Django Auth自帶的User模型字段有限，我們需要對其進行拓展(直接使用也可以)

nickname = models.CharField(verbose_name=u'昵稱',max_length=50, blank=True)user_avatar = models.ImageField(verbose_name=u'用戶頭像', upload_to='image/%Y/%m/%d', default=u'image/default.png', max_length=500)user_email = models.EmailField(verbose_name=u'用戶郵箱',max_length=254)user_phone = models.BigIntegerField(verbose_name=u'手機號', null=True,blank=True)user_birthday = models.DateField(verbose_name=u'出生日期', default = timezone.now)user_sex = models.CharField(verbose_name=u'性別',max_length=6,choices=(('male','男'),('female','女')),default='male')user_address = models.CharField(verbose_name=u'地址',max_length=550, blank=True,null=True)signature = models.CharField(verbose_name=u'個性簽名',max_length=550, blank=True,null=True)

用戶接口序列化

from rest_framework import serializersclass UserSerializer(serializers.ModelSerializer):class Meta:  model = User  fields = "__all__"

登陸接口設計

class UserLogin(APIView):  def post(self,request):    params = request.data    userName = get_openid(params.get('code'))    userInfo = params.get('userinfo')    try:      user = User.objects.get(username = userName)    except Exception as e:      user = None    if user:      # 更新用戶信息      user = User.objects.get(username = userName)    else:      #注冊新用戶      user = User.objects.create_user(username=userName,password=random_str(10))      #手動生成JWT    # 手動生成token驗證    jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER    jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER    payload = jwt_payload_handler(user)    token = jwt_encode_handler(payload)    ret = {'code': '00000', 'msg': None,'data':{}}        ret['msg'] = '授權成功'    ret['data'] = {      'token': token,      'user_id': user.id,      'nickname': user.nickname    }    return JsonResponse(ret)

解析code獲取openid

class OpenidUtils(object):  def __init__(self, jscode):    self.url = "https://api.weixin.qq.com/sns/jscode2session"    self.appid = APPID    self.secret = SECRET    self.jscode = jscode  # 前端傳回的動態jscode  def get_openid(self):    url = self.url + "?appid=" + self.appid + "&secret=" + self.secret + "&js_code=" + self.jscode + "&grant_type=authorization_code"    r = requests.get(url)    openid = r.json()['openid']    return openid
