Python EVE：- 在 Python EVE 中为某些端点阻止 POST 方法和启用 PUT 方法

Question

我最初编写 webservice 是为了允许在所有端点上使用 'GET' 和 POST 方法。现在我们的网络服务工作流程发生了一些变化，我们想要阻止某些端点的 POST 端点并为它们启用 PUT 某些端点仍将启用 POST。

我会通过添加 settings.py

的代码片段来解释更多

# pulling DBSchema from DBTableSchema
from DBSchema.DBTableSchema import DBTableSchema
from Configs import Configs

dbtableSchema = DBTableSchema()


# Let's just use the local mongod instance. Edit as needed.
# Please note that MONGO_HOST and MONGO_PORT could very well be left
# out as they already default to a bare bones local 'mongod' instance.

## LOCALHOST ENTRIES
MONGO_HOST = Configs.MONGO_DB_HOST
MONGO_PORT = Configs.MONGO_DB_PORT
MONGO_USERNAME = Configs.MONGO_DB_USER_NAME
MONGO_PASSWORD = Configs.MONGO_DB_PASSWORD
MONGO_DBNAME = Configs.MONGO_DB

# Enable reads (GET), inserts (POST) and DELETE for resources/collections
# (if you omit this line, the API will default to ['GET'] and provide
# read-only access to the endpoint).
RESOURCE_METHODS = ['GET', 'PATCH', 'POST', 'DELETE']

# Enable reads (GET), edits (PATCH), replacements (PUT) and deletes of
# individual items  (defaults to read-only item access).
ITEM_METHODS = ['GET', 'PATCH', 'PUT', 'DELETE', 'POST']

# Used for implementing user-resource restricted access.
# Returns the documents which are associated with particular user

AUTH_FIELD = 'userid'

people = {
    'item_title': 'person',
    'cache_control': 'max-age=10,must-revalidate',
    'cache_expires': 10,
    'resource_methods': ['GET', 'POST'],
    'schema': dbtableSchema.schema_people,
    'public_methods': ['POST']
}

org = {
    'item_title': 'org',
    'cache_control': 'max-age=10,must-revalidate',
    'cache_expires': 10,
    'resource_methods': ['GET', 'PATCH'],
    'schema': dbtableSchema.schema_people_org
}

puburl = {
    'item_title': 'puburl',
    'cache_control': 'max-age=10,must-revalidate',
    'cache_expires': 10,
    'resource_methods': ['GET', 'PATCH'],
    'schema': dbtableSchema.schema_people_pub_url
}

address = {
    'item_title': 'address',
    'cache_control': 'max-age=10,must-revalidate',
    'cache_expires': 10,
    'resource_methods': ['GET', 'PATCH'],
    'schema': dbtableSchema.schema_people_address
}

contactnumber = {
    'item_title': 'contactnumber',
    'cache_control': 'max-age=10,must-revalidate',
    'cache_expires': 10,
    'resource_methods': ['GET', 'PATCH'],
    'schema': dbtableSchema.schema_people_contact_number
}

template = {
    'item_title': 'template',
    'cache_control': 'max-age=10,must-revalidate',
    'cache_expires': 10,
    'resource_methods': ['GET', 'POST'],
    'schema': dbtableSchema.schema_template
}

usersharedcontacts = {
    'item_title': 'usersharedcontacts',
    'cache_control': 'max-age=10,must-revalidate',
    'cache_expires': 10,
    'resource_methods': ['GET', 'PATCH'],
    'schema': dbtableSchema.schema_people_with_user_shared_contacts
}

cardholder = {
    'item_title': 'cardholder',
    'cache_control': 'max-age=10,must-revalidate',
    'cache_expires': 10,
    'resource_methods': ['GET', 'PATCH'],
    'schema': dbtableSchema.schema_people_card_holder
}

DOMAIN = {
   'people': people,
   'org': org,
   'puburl': puburl,
   'address': address,
   'contactnumber': contactnumber,
   'template': template,
   'usersharedcontacts': usersharedcontacts,
   'cardholder': cardholder
}

我想为 people 和 template 端点启用 POST 方法，如您所见，我已经为上述端点进行了此配置 'resource_methods': ['GET', 'POST'] .

我还想为其余端点禁用 POST 方法，因此我为其余端点 'resource_methods': ['GET', 'PATCH'], 配置了以下内容。

我也配置了RESOURCE_METHODS = ['GET', 'PATCH', 'POST', 'DELETE']

但是当我尝试运行应用程序时，我在以下类型的控制台上收到错误

eve.exceptions.ConfigException: Unallowed [usersharedcontacts] resource    method(s): PATCH. Supported: GET, POST, DELETE

Process finished with exit code 1

Answer 1

PATCH 是一个文档（项目）方法，而不是资源方法，这就是你得到一个 Unallowed 异常的原因。尝试：

'resource_methods': ['GET'],  # read-only resource endpoint
'item_methods': ['PATCH']     # still allow edits at the document endpoint

有关详细信息，请参阅文档中的 CRUD Operations table。
