URL読み取りを使用してhttpsページをダウンロードしようとしています:
str=urlread('https://funds.barclaysstockbrokers.co.uk/clients/bsl/search_factsheet_summary.aspx?code=B0XWN14')
残念ながら、エラーが発生します:
Error downloading URL. Your network connection may be down or your proxy settings improperly configured.
urlread2 を使ってみた (http://www.mathworks.co.uk/matlabcentral/fileexchange/35693-urlread2/content/urlread2.m)
しかし、それは私にこのエラーを与えます:
Response stream is undefined
below is a Java Error dump (truncated):
??? Error using ==> urlread2 at 217
Java exception occurred:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
私は何をする必要がありますか?
