Question

尝试使用Google App Engine的remote_api，以便我们可以通过IDE进行逐行调试。

远程api起初效果很好。该应用程序能够成功从数据库中检索信息。当wepapp响应客户端浏览器时会发生错误。

守则：

这与app引擎documentation中提供的示例非常相似：

from model import My_Entity
from google.appengine.ext.remote_api import remote_api_stub

# Test database calls
def get(w_self):
    remote_api_stub.ConfigureRemoteApi(None, '/_ah/remote_api', auth_func, 'myapp.appspot.com')

    t_entity = My_Entity.get_by_key_name('the_key')

    w_self.response.set_status(200)

    # The error occurs AFTER this code executes, when webapp actually responds to the browser

错误追溯：

该错误似乎与blobstore有关。

远程api是否在代码中太晚了？

... webapp通过localhost服务器对blobstore做了什么？然后远程api可能会将请求重定向到服务器中的blobstore而不是webapp期望它的localhost调试服务器？

Traceback (most recent call last):

    get_blob_storage())
  File "C:\Program Files (x86)\Google\google_appengine\google\appengine\tools\dev_appserver_blobstore.py", line 79, in GetBlobStorage
    return apiproxy_stub_map.apiproxy.GetStub('blobstore').storage
AttributeError: 'RemoteStub' object has no attribute 'storage'

远程api是否应该在代码中的其他位置初始化？

或者这个问题与其他问题有关吗？

非常感谢！

要使其正常工作，您可以使用测试平台的帮助来启动缺少的存根：

ADDRESS=....
remote_api_stub.ConfigureRemoteApi(None, '/_ah/remote_api', auth_func, ADDRESS)

# First, create an instance of the Testbed class.
myTestBed = testbed.Testbed()

# Then activate the testbed, which prepares the service stubs for use.
myTestBed.activate()

# Next, declare which service stubs you want to use.
myTestBed.init_blobstore_stub()
myTestBed.init_logservice_stub()

使用GAE remote api从localhost进行调试 - 连接太晚了？
