在pythoneve应用程序中执行PUT，PATCH返回时，请求的URL不允许使用该方法

Question

我有一个使用pythoneve编写的web服务。我正在尝试对已创建的资源执行PUT请求。我已经在我的settings.py文件中将item_methods定义为PATCH，但是当我进行调用时，得到了以下响应：

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

在请求有效负载和我要点击的URL之后

网址：-http://127.0.0.1:5000/puburl/

请求有效载荷：-

我的settings.py文件如下：

我认为问题是etag必须在头中，子句'If Match'=etag。在

您可以在http://python-eve.org/features.html中查看有关“数据完整性和并发控制”的更多信息

Answer 2

乍一看，我会说您正在访问的URL（http://127.0.0.1:5000/puburl/）看起来像一个资源（集合）端点，而PUT是文档（项）端点。这就是为什么要将它添加到item_methods而不是resource_methods。为了使http://127.0.0.1:5000/puburl/<id>工作，您需要点击类似http://127.0.0.1:5000/puburl/<id>的内容。在
