SSLError：无法连接到HTTPS URL，因为Google App Engine上没有可用的SSL模块。

Question

要使用wechat sdk创建菜单

WeChat.create_menu({
     "button":[
     {    
          "type":"click",
          "name":"Daily Song",
          "key":"V1001_TODAY_MUSIC"
      },
      {
           "type":"click",
           "name":" Artist Profile",
           "key":"V1001_TODAY_SINGER"
      },
      {
           "name":"Menu",
           "sub_button":[
           {    
               "type":"view",
               "name":"Search",
               "url":"http://www.soso.com/"
            },
            {
               "type":"view",
               "name":"Video",
               "url":"http://v.qq.com/"
            },
            {
               "type":"click",
               "name":"Like us",
               "key":"V1001_GOOD"
            }]
       }]
 })

由于此错误，当前无法工作：

SSLError: Can't connect to HTTPS URL because the SSL module is not available.

python请求模块包含在app engine项目中。使用Python2.7。正在寻找解决这个问题的方法，但是还没有找到很清楚的方法来解决这个问题

Answer 1

如果您使用的是GAE的套接字，只需加载SSL库就可以获得SSL支持，而无需任何黑客攻击。

只需将此添加到app.yaml文件：

libraries:
- name: ssl
  version: latest

这记录在Google Cloud's OpenSSL Support documentation.

Answer 2

This blog post details a solution。从博客文章：

The problem is GAE has a “whitelist” of select standard libraries. SSL (_ssl, _socket) is not one of them. So, we need to tweak the sandbox environment (dangerous) carefully. The below code uses the standard Python socket library instead of the GAE-provided in the development environment. Modify [or create] appengine_config.py:

import os

# Workaround the dev-environment SSL
#   http://stackoverflow.com/q/16192916/893652
if os.environ.get('SERVER_SOFTWARE', '').startswith('Development'):
    import imp
    import os.path
    from google.appengine.tools.devappserver2.python import sandbox

    sandbox._WHITE_LIST_C_MODULES += ['_ssl', '_socket']
    # Use the system socket.
    psocket = os.path.join(os.path.dirname(os.__file__), 'socket.py')
    imp.load_source('socket', psocket)

If you're using GAE's Sockets, you can get SSL support without any hacks by simply loading the SSL library.

Simply add this to your app.yaml file:

libraries: - name: ssl
- version: latest

如果您遇到RAND_egd错误，只需将app.yaml中的“-version:latest”更改为“-version:2.7”！
