23.绑定微博用户

1. 微博绑定用户接口

1.1 oauth/urls.py中添加路由

urlpatterns = [
    path('weibo/binduser/', views.OauthWeiboBindUser.as_view()),
]

1.2 oauth/views.py 中添加视图函数

class OauthWeiboBindUser(APIView):
    permission_classes = (AllowAny,)

    def post(self, request):
        # 绑定用户, 1. 已注册用户, 2. 未注册用户
        # 1.1 获取用户名, 密码, weibo_uid
        username = request.data.get('username')
        password = request.data.get('password')
        weibo_uid = request.data.get('weibo_uid')
        if not all([username, password, weibo_uid]):
            return Response({'code': 999, 'msg': '参数不全'})
        # 0.判断是否存在此用户
        try:
            user = User.objects.get(username=username)
        except Exception as e:
            user = None
        # 1. 已注册用户
        if user:
            # 如果存在就验证 密码, 验证通过,就绑定, 返回token,登录成功
            if user.check_password(password):
                ou = OauthUser(uid=weibo_uid, user=user, oauth_type='1')  # 绑定
                ou.save()
                payload = jwt_payload_handler(user)  # 通过user对象获取到jwt的payload信息
                token = jwt_encode_handler(payload)  # 生成token
                data = jwt_response_payload_handler(token, user)
                data['type'] = '0'  # 指定为登录成功
                return Response({'code': 0, 'msg': '登录成功', 'data': data})
            else:
                return Response({'code': 999, 'msg': '密码错误'})
        else:
            # 2. 未注册用户
            # 生成新用户, 设置用户名密码, 保存, 然后绑定, 返回token, 登录成功
            user = User(username=username)
            user.set_password(password)
            user.save()
            ou = OauthUser(uid=weibo_uid, user=user, oauth_type='1')
            ou.save()
            payload = jwt_payload_handler(user)
            token = jwt_encode_handler(payload)
            data = jwt_response_payload_handler(token, user)
            data['type'] = '0'  # 指定为登录成功
            return Response({'code': 0, 'msg': '登录成功', 'data': data})

2. vue绑定用户页面

<template>
  <div>
    <div v-show='visiable'>
      绑定用户
      用户名: <input
      type="text"
      v-model="username"
      @blur="check_username"
    >
      <span>{{username_message}}</span>
      密码: <input
      type="password"
      v-model="password"
    >
      <button @click="bindUser">绑定</button>
    </div>
  </div>
</template>
<script>
  import { oauth_callback_post, oauth_binduser_post, user_count } from './axios_api/api'
  export default {
    data() {
      return {
        visiable: false, // 绑定用户窗口
        uid: '', // weibo_uid
        username: '',
        password: '',
        username_message: '',
        username_error: false
      }
    },
    mounted() {
      this.getCode()
    },
    methods: {
      // 判断用户名
      check_username() {
        console.log('判断用户名')
        console.log(this.username == '')
        var reg = new RegExp(/^[a-zA-Z0-9_-]{4,16}$/); //字符串正则表达式 4到14位（字母，数字，下划线，减号）
        if (this.username == '') {
          this.username_message = '用户名不能为空'
          this.username_error = true
          return false
        }
        if (!reg.test(this.username)) {
          this.username_message = '用户名格式不正确'
          this.username_error = true
          return false
        } else {
          // 去后端检查用户名使用数量
          user_count({ type: 'username', data: this.username }).then((res) => {

              this.username_error = false
            }
          })
        }
      },
      getCode() {
