我想将 ★（星号）字符保存到应用引擎数据存储区，但我遇到了编码/解码问题。

  • 不幸的是，它适用于开发服务器，但不适用于生产。
  • 在以前的应用程序quopri.decodestring上解决了我的问题

首先，我从 AngularJS ajax 表单（应该是无关紧要的）：

$http({
       method: 'POST',
       url: the_upload_url,
       transformRequest: formDataObject,
       data: event,
       headers: {'Content-Type': false}
       })

我有一个webapp2.RequestHandler& blobstore_handlers.BlobstoreUploadHandler：

class EditEventHandler(ApiHandler, blobstore_handlers.BlobstoreUploadHandler):
    def post(self):
         ...
         print self.request.get('message', 'none')
         print len(self.request.get('message', 'none'))
         message = unicode(quopri.decodestring(self.request.get('message', 'none')), 'iso_8859-2')
         print message
         print len(message)
         ...
         #save message to datastore in ndb.TextProperty & send response

以下是应用引擎仪表板的日志输出：

如您所见，星形已转换为4piF. 我哪里错了？

问题是，如果您不指定 webob 的版本，appengine 使用旧的 webob 以实现兼容性（我想开发服务器默认使用新的 webob，因此存在差异）。然而，旧版本的 webob 忽略了编码，这是一个错误。

对我来说，这很容易通过添加新的 webob 来解决：

libraries:
- name: webob
  version: "1.2.3"

如果您不想升级 webob 版本，还有一个猴子补丁。
