Question

我必须处理登录用户的身份验证和授权。

我在Angular中创建了一个注册表单，为此，我在注册时使用python flask创建了一个后端API，注册数据将保存到表中，之后，我必须进行登录用户身份验证，授权，我不知道如何进行。

我正在分享我的注册代码。

HTML：

 <form (ngSubmit)="onSubmit(register)" #register="ngForm">
      <mat-form-field class="example-full-width">
         <input matInput placeholder="First Name"  name="first_name" [(ngModel)]="first_name" required>
      </mat-form-field>

      <mat-form-field class="example-full-width">
        <input matInput placeholder="Last Name"  name="last_name" [(ngModel)]="last_name" required>
       </mat-form-field>

      <mat-form-field class="example-full-width">
       <input matInput placeholder="Email ID" name = "email"   [(ngModel)]= "email" required>
      </mat-form-field>


       <mat-form-field class="example-full-width">
         <input matInput placeholder="Mobile Number"  name  = "mobile_number"  [(ngModel)]= "mobile_number"  required>
      </mat-form-field>

       <mat-form-field class="example-full-width">
         <input matInput placeholder="Password"  name = "password"   [(ngModel)]= "password" required >
        </mat-form-field>

        <mat-form-field class="example-full-width">
           <input matInput placeholder="Confirm Password"  name = "confirm_password"  [(ngModel)]= "confirm_password" required>
          </mat-form-field>
            <button type="submit" class="btn float-center btn-sm shadow btnSForm" >Submit</button>
    </form>

Python烧瓶：

   from flask_login import UserMixin
   from APIs import db, ma


   # In this class we are declaring the table columns to be created in the table.
   class Registration(db.Model):
       reg_id = db.Column(db.Integer, primary_key=True)
       usercred_id = db.relationship('UserCredentials', backref='registration', uselist=False)
       first_name = db.Column(db.String(32), unique=False, nullable=False)
       last_name = db.Column(db.String(32), unique=False, nullable=False)
       email = db.Column(db.String(255), unique=True, nullable=False)
       mobile_number = db.Column(db.BIGINT, unique=False, nullable=True)
       password = db.Column(db.String(255), unique=False, nullable=False)

   class UserCredentials(db.Model, UserMixin):
        usercred_id = db.Column(db.Integer, primary_key=True, nullable=False)
        email = db.Column(db.String(255), unique=True, nullable=False)
        password = db.Column(db.String(255), unique=False, nullable=False)
        industry_id = db.Column(db.Integer, unique=False, nullable=True)
        subindustry_id = db.Column(db.Integer, unique=False, nullable=True)
        reg_id = db.Column(db.Integer, db.ForeignKey('registration.reg_id'), nullable=False)

  # This class is the sub-class for converting the data into json format, this class is using marshmallow.
 class Schema(ma.ModelSchema):
    class Meta:
      model = Registration

   def addRegister(register_data, user_data):
       try:
          reg = Registration(**register_data)
          usr = UserCredentials(**user_data, registration=reg)
          db.session.add(reg, usr)
          db.session.commit()
          return True
       except Exception:
         return False
       finally:
         db.session.close()

@app.route("/registration", methods=["GET", "POST"])
def post():
    if request.method == 'POST':
        save_data = request.get_json()
        try:
            return jsonify(addRegister(save_data))
        except Exception:
            return jsonify({'Unsuccessful': 'Looks like you missed something'})
