获取 InvalidURLError: ApplicationError: 1 在 URLFetch 中
我遇到了以下错误：
InvalidURLError: ApplicationError: 1
我检查了我的代码，记录了一些不同的内容，导致这个错误的 URL 看起来都很正常。通过 urllib.quote 处理后，直接在浏览器中访问这些 URL 也能得到正常的结果。
这个错误出现在很多 URL 上，而不是只有一个。这个 URL 指向一个 API 服务，并且是在应用程序内部构建的。
顺便说一下，这里有一个链接，可以查看 google.appengine.api.urlfetch 的源代码： http://code.google.com/p/googleappengine/source/browse/trunk/python/google/appengine/api/urlfetch.py?r=56。
文档中提到，当 URL 无效时会出现错误：“如果 URL 无效则会抛出 InvalidURLError。”并且“如果 URL 是空字符串或明显无效，我们会抛出 urlfetch.InvalidURLError。”
为了让想测试的人更简单：

from google.appengine.api import urlfetch
result = urlfetch.fetch(url=url)
这是错误追踪信息： Traceback (most recent call last): File "", line 1, in File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/urlfetch.py", line 263, in fetch return rpc.get_result() File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/apiproxy_stub_map.py", line 592, in get_result return self.__get_result_hook(self) File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/urlfetch.py", line 359, in _get_fetch_result raise InvalidURLError(str(err)) InvalidURLError: ApplicationError: 1
我在想，可能是我漏掉了什么很简单的东西。希望能听到你们的意见和想法。谢谢！
