在 python 前夕应用程序 returns 中执行 PUT 和 PATCH，所请求的方法不被允许 URL

Question

我有一个使用 Python Eve 的书面网络服务。我正在尝试对已创建的资源执行 PUT 请求。我在我的 settings.py 文件中将 item_methods 定义为 PATCH，但是我在拨打电话时收到以下响应：-

{
  "_status": "ERR",
  "_error": {
      "message": "The method is not allowed for the requested URL.",
      "code": 405
  }
}

跟随请求负载和我正在点击的 URL

URL :- http://127.0.0.1:5000/puburl/

请求负载：-

[
 {
  "puburl": "https://github.com/tushar",
  "userid": "xFGellL",
  "_etag": "714df986e0bf802962a6b8cb4b9b1513e1709d7b"
 }
]

我的 settings.py 文件如下：-

__author__ = 'sappal'

# 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.

# out as they already default to a bare bones local 'mongod' instance.

MONGO_HOST = Configs.MONGO_DB_HOST
MONGO_PORT = Configs.MONGO_DB_PORT

MONGO_DBNAME = Configs.MONGO_DB

关于通话失败原因的任何想法..

Answer 1

我认为问题是 etag 必须在 headers with clause 'If-Match' = etag.

您可以在 http://python-eve.org/features.html

中查看有关 "Data Integrity and Concurrency Control" 的更多信息

Answer 2

乍一看，我会说您正在点击的 URL (http://127.0.0.1:5000/puburl/) 看起来像一个资源（集合）端点，而 PUT 是一个文档（项目）端点.这就是您将其添加到 item_methods 而不是 resource_methods 的原因。您想点击 http://127.0.0.1:5000/puburl/<id> 之类的东西以使 PUT 起作用。
