Google App Engine + Python中的REST API？

Question

如何使用Google App Engine和Python创建RESTful API？我尝试过使用Cloud Endpoints,但文档并没有关注RESTful API.对于GAE,有类似于django-tastypie的东西吗？

Answer 1

RESTful api可以基于EndPoint API构建.有一些工具可以帮助您简化事情:

appengine rest服务器(不基于端点)

适用于Google App Engine应用程序的嵌入式服务器,可通过REST API公开您的数据模型,无需额外工作.

另一个是基于端点

通过扩展ndb.Model类和端点库提供的功能,此库允许您直接与API方法中的模型实体交互,而不是与ProtoRPC请求交互.例如,而不是:

EDIT1:

我为端点编写了一个RESTFul api生成器.

# generate restful api in one line
BigDataLab = EndpointRestBuilder(GPCode).build(
    api_name="BigDataLab",
    name="bigdatalab",
    version="v1",
    description="My Little Api"
)

我已经通过webapp2为NDB模型创建了一个完整的REST API.包括权限处理等等.

很想听听你的想法:

class MyModel(ndb.Model):
  property1 = ndb.StringProperty()
  property2 = ndb.StringProperty()
  owner = ndb.KeyPropertyProperty(kind='User')

  class RESTMeta:
    user_owner_property = 'owner' # When a new instance is created, this property will be set to the logged-in user
    include_output_properties = ['property1'] # Only include these properties for output

app = webapp2.WSGIApplication([
    # Wraps MyModel with full REST API (GET/POST/PUT/DELETE)
    RESTHandler(
      '/api/mymodel', # The base URL for this model's endpoints
      MyModel, # The model to wrap
      permissions={
        'GET': PERMISSION_ANYONE,
        'POST': PERMISSION_LOGGED_IN_USER,
        'PUT': PERMISSION_OWNER_USER,
        'DELETE': PERMISSION_ADMIN
      },

      # Will be called for every PUT, right before the model is saved (also supports callbacks for GET/POST/DELETE)
      put_callback=lambda model, data: model
    ),

    # Optional REST API for user management
    UserRESTHandler(
        '/api/users',
        user_model=MyUser, # You can extend it with your own custom user class
        user_details_permission=PERMISSION_OWNER_USER,
        verify_email_address=True,
        verification_email={
            'sender': 'John Doe <john@doe.com>',
            'subject': 'Verify your email address',
            'body_text': 'Click here {{ user.full_name }}: {{ verification_url }}',
            'body_html': '<a href="{{ verification_url }}">Click here</a> {{ user.full_name }}'
            },
        verification_successful_url='/verification_successful',
        verification_failed_url='/verification_failed',
        reset_password_url='/reset_password',
        reset_password_email={
            'sender': 'John Doe <john@doe.com>',
            'subject': 'Please reset your password',
            'body_text': 'Reset here: {{ verification_url }}',
            'body_html': '<a href="{{ verification_url }}">Click here</a> to reset'
            },
        )
], debug=True, config=config)
