urlfetch - DownloadError in App Engine when requesting specific urls -

-

i'm getting strange downloaderror while trying request specific url using urlfetch.fetch

here example code:

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 er:     logging.exception(er)

and here error:

unable 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     result = urlfetch.fetch(url, deadline=50, validate_certificate=false)   file "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/api/urlfetch.py", line 271, in fetch     return rpc.get_result()   file "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/api/apiproxy_stub_map.py", line 613, in get_result     return self.__get_result_hook(self)   file "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/api/urlfetch.py", line 414, in _get_fetch_result     raise downloaderror("unable fetch url: " + url + error_detail) downloaderror: unable fetch url: https://iiko.net:9900/api/0/auth/access_token

i'm sure it's not connected deadlines, because code fails in few seconds.

possibly it's connected broken ssl cerificate on website, or gae ip-addresses blocked reason site, can't contact them right now.

any appreciated, thanks!

the reason of problem broken ssl certificate, works fine. walkaround used proxy server, know it's not perfect solution, have no idea how fix on app engine level.

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor
