将Acces-Control-Allow-Origin添加到app.yml [英] Adding Acces-Control-Allow-Origin to app.yml

问题描述

我正在遵循Google App Engine文档中的以下说明：

I'm following these instructions from Google App Engine docs :

https://cloud.google.com/appengine/docs/python/config/appref

如果您搜索CORS时，会看到我要复制的示例。

If you search for CORS, you'll see the example I am trying to copy.

我的app.yaml文件如下：

My app.yaml file looks like:

runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /.*
  script: main.app
  http_headers: Access-Control-Allow-Origin: *

libraries:
- name: ssl
  version: latest

但是当我进行更新时，会出现此错误：

However when I go to update it I get this error:

appcfg.py: error: Error parsing ./app.yaml: Unable to assign value 'Access-Control-Allow-Origin' to attribute 'http_headers':
Value 'Access-Control-Allow-Origin' for http_headers is not of the expected type HttpHeadersDict

为什么会出现此错误？我在做什么与文档不同？

Why am I getting this error? What am I doing differently than the docs?

推荐答案

不幸的是，这无效 yaml 。

您有缩进问题。另外，您必须引用 * 。应该是：

You have an indentation problem. Also you have to quote the *. Should be:

handlers:
- url: /.*
  script: main.app
  http_headers: 
    Access-Control-Allow-Origin: "*"
