尝试使用 urlfetch.fetch 请求特定 url 时出现奇怪的 DownloadError
这是示例代码:
url = 'https://iiko.net:9900/api/0/auth/access_token'
try:
result = urlfetch.fetch(url, deadline=50, validate_certificate=False)
if result.status_code == 200:
pass
except DownloadError as er:
logging.exception(er)
这是错误:
Unable to fetch URL: https://iiko.net:9900/api/0/auth/access_token
Traceback (most recent call last):
File "/base/data/home/apps/s~iappintheair/phil-dev.383038517236330514/handlers/api/test.py", line 18, in get

raise DownloadError("Unable to fetch URL: " + url + error_detail)
DownloadError: Unable to fetch URL: https://iiko.net:9900/api/0/auth/access_token
我确定它与截止日期无关,因为此代码会在几秒钟内失败。
可能与此网站上损坏的 ssl 证书有关,或者 GAE ip-addresses 因某种原因被此网站阻止,但我现在无法联系他们。
任何帮助表示赞赏,谢谢!
