在python eve应用程序中执行PUT，PATCH返回，请求的URL不允许该方法

Question

我有一个使用 Python Eve 编写的网络服务。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，但是当我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
  }
}

按照请求有效负载和我点击的 URL

网址：- http://127.0.0.1:5000/puburl/

请求有效负载：-

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

我的settings.py 文件如下：-

__author__ = 'sappal'

from DBSchema.DBTableSchema import DBTableSchema
from Configs import Configs

dbtableSchema = DBTableSchema()


# Let's just use the local mongod instance. Edit as needed.

关于呼叫失败的任何想法..

Answer 1

乍一看，我会说您访问的 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，以便 PUT 工作。

Answer 2

我认为问题在于 etag 必须位于带有子句 'If-Match' = etag 的标题中。
