python3上的SSL错误获取请求

Question

I'm trying to access a table on factfinder.census.gov via their API .

I've tried the solutions listed here and tried using http, all sorts of variants of this code, etc. In fact, I can't even seem to do a simple get (I'm using python requests) on http://factfinder.census.gov/ at all.

Eg,

https://factfinder.census.gov/service/data/v1/en/programs/DEC/datasets/10_SF1/tables/GCTPH1/data/0100000US.04000

I had to tack on a user access key (from https://factfinder.census.gov/service/UserAccessKey.html ) to get access, and then I could just paste https://factfinder.census.gov/service/data/v1/en/programs/DEC/datasets/10_SF1/tables/GCTPH1/data/0100000US.04000?key=MYKEY and it worked fine in private/incognito mode by just pasting it into my browser url bar)

However, I'm getting

Error

requests.exceptions.SSLError: HTTPSConnectionPool(host='factfinder.census.gov', port=443): Max retries exceeded with url: /service/data/v1/en/programs/DEC/datasets/10_SF1/tables/GCTPH1/data/0100000US.04000?key=MYKEY (Caused by SSLError(SSLError(1, '[SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:598)'),))

我冒昧地猜测您正在使用http而不是https查询发布的链接（ http://factfinder.census.gov/ ）（注意，如果单击该链接，它会重定向到https），该站点使用SSL加密，正在拒绝未加密的连接尝试。
