本项目是参考 https://zhuanlan.zhihu.com/p/101544546 建立的基于flask的快速开发框架 特点如下：

• 支持持久化-》postgresql
• 支持单元测试
• 支持restful api

This project template is very similar to the one written by Leo-G, found here: https://github.com/Leo-G/Flask-SQLALchemy-RESTFUL-API

This project is a simple Dog-Owner tracker. The owners are considered Users, and we've set up Users, and roles (among other things) through Flask-Security. The models (found in db > models.py) are declared and managed using SQLAlchemy. The Flask-Restful API can be seen throughout the project, though the dog.py and owner.py files in the resources directory will be of most use when figuring out how to set up the HTTP methods through class-based methods.

We're using Flask-JWT for authentication and authorization.

The configuration for Flask-migrate can be seen in the migrate.py file in the project root.

As in the project by Leo-G, we make use of marshmallow and marshmallow_jsonapi for JSON and data validation. Schemas are declared for every model in the models.py file, and validation is performed in the different resource files.

• flask
• flask-security
• flask-restful
• flask-cors
• flask-sqlalchemy
• flask-migrate
• flask-script
• flask-jwt
• marshmallow
• marshmallow_jsonapi
• pyscopg2

Create your DB in Postgres using the credentials stored in the config/base_settings.py file (see the setup.md file for instructions on doing this), and then run the following from the project root:

python3 migrate.py db init
python3 migrate.py db migrate
python3 migrate.py db upgrade

When sending a POST request in order to create a new object (in this case, a Dog), you will need to follow a very strict format, or the JSON validator will reject it. This format is the following:

{
    "data": {
        "type": "dog",
        "attributes": {
            "dog_type": "INSERT DOG TYPE HERE"
        }
    }
}

Note: If make sure the value for the "type" key matches the "type" value in the Meta class of whatever Schema used to validate your object. You also can input however many attributes for your object as you'd like in the "attributes" dictionary.

As you can see in the user.py file, all of the CRUD features for the User class are protected by the decorator jwt_required(). This means that a valid Authorization token is needed in order to reach those endpoints and perform that logic. In order to get a valid auth token, send a POST request to this url: /api/v1/auth with the Content-Type Header of application/json, passing in the following:

{
    "ownername": "EMAIL",
    "ownerpassword": "PASSWORD"
}

Note: Rather than the JWT standard of "username" and "password" as the authorization keys, we've specified different keys, really just to show that you can. These keys are declared in the respective config files.

Once you send that request, you should get the following back:

{
    "access_token": "AUTH_TOKEN"
}

Using this token, you can then call the protected endpoints by adding the following headers to your calls:

Authorization : JWT AUTH_TOKEN

Note: Again, you can change the "JWT" value in the Auth header in the config file. We just chose not to in order to not conflict with OAuth2 Bearer tokens (as per the JWT documentation).

You'll notice that there are several lines of code under the "Bootstrap Several Users" section in main.py. These users will be created if there are no users in the database, once you run the server, and hit an endpoint. I recommend using Postman to hit the endpoint localhost:5000/api/v1/dogs to get these users started.

Note: Make sure that once you're aware of this code there and the users that they create if using this boilerplate for a production-level application!
