pypostcode's Issues

Add PyPi support

would be nice to have it installable via pip

Adapt it to use Postcode API v3

Eventually the version 2 of Postcode API will get deprecated, it will need to be updated to allow to use v3.

API documentation: https://www.postcodeapi.nu/docs/v3/

Make version 2 API as default

Update in march when version 1 will be shutdown

Limitations using "huisletter" and "toevoeging"

Perhaps an implementation issue in postcodeapi.nu itself, but I've not yet found how the API is to differentiate between "1185ZH/7/G" and "1185ZH/7/G/BIS" (see https://www.postcode.nl/1185ZH/7/G with 43m2 and https://www.postcode.nl/1185ZH/7/G%20BIS with 32m2)

Instead, the API seems to return (with "view=bag" added) in both cases the id="0362010002002946" VBO; which can be queried for via https://service1.kadaster.nl/bag/bag-burger/secured/selectie, using "Verblijfsobject" (VBO) and the id above... showing that it belongs to "1185ZH/7/A"

Looking at the (current) "bag-adressen-bagaveen.csv.gz" file downloaded from http://data.nlextract.nl/bag/csv/; it shows that "VBO 0362010002002951"="1185ZH/7/G" and "VBO 0362010002182896"="1185ZH/7/G/BIS"; which can be confirmed by above Kadaster search feature... and note how the m2 values match the postcode.nl checks.

To me it seems like postcodeapi.nu is (incorrectly) ignoring "huisletter" and "huisnummertoevoeging" when parsing the BAG extract (and I assume that they use similar files like the ones that can be obtained from http://data.nlextract.nl/bag/csv/ (maybe more directly from the source agencies). It appears that their implementation always returns the first "7" found (or perhaps imported?) and ignoring any further detailing.

Now, as said, this might be due to me not correctly reading the API documentation for this service at http://api.postcodeapi.nu/docs/resources/housenumber

pypi

Hey Stefan,

I cannot find the pyPostcode 0.2 on https://pypi.python.org.
Do you still have to push this?

Python 2.7.6: _ssl.c:510: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure>

FYI / FWIW:

On Ubuntu 14.04.5 LTS (with Python 2.7.6) the example.py does not work. See below.

The error

urllib2.URLError: <urlopen error [Errno 1] _ssl.c:510: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure>

is a common problem with older python versions in combination with TLS and possibly SNI (Server Name Indication). So far I have not found a solution or workaround within python 2.7.6.
With python 2.7.11 it works fine.

It's easy to reproduce with three lines of code:
