* [PHP-Symfony] fixes validation of date-time parameter
This fixes parts of #14930.
Without this patch a parameter declared as date-time
is validated against Symfony's "DateTime" constraint,
which always fails. Because this constraint expects
a string with format "Y-m-d H:i:s".
It fails because the generated code performs the check
after the deserialization, so the variable checked is not
a string anymore.
Besides this, even if we performed that validation on the
string, that would not work well because OpenApi
specification expects date-time to conform to RFC 3339
and that "Y-m-d H:i:s" would reject RFC 3339 compliant dates.
With this change we ensure that the string provided by the
web user could be parsed by PHP to DateTime, which solves both issues.
(Note however that it means that it now accepts more formats than just
RFC 3339 compliant ones for those parameters (it would accept all formats
accepted by PHP DateTime). That being said it's compliant with the guideline
""be conservative in what you send, be liberal in what you accept")
* [PHP-Symfony] Fix handling of null date-time parameter
This fixes one of the issue described on #14930, namely that
the deserializeString method of the generated class JsmSerializer returns null
for other types of string, but not for date-time. Instead it returns a DateTime
which represents "now" (because that what `new DateTime(null)` does).
Consequently when an API declares a date-time parameter as non-required and
when that endpoint is called without that parameters, then the user code
would end up having "now" instead of "null" for this parameter.
* Removed commented code
* Input validation is now supported as strict JSON validation
* [PHP][Symfony] Improve the implementation
Closes#6614
* Generated code is tested to assure it compiles and updated README to dynamically load dependencies via composer
* Updated shell script because shippable tests were failing
