multiple occurrance of parameters in query string #43

Closed Spongman closed 4 years ago

Spongman commented 4 years ago

TS-0009, 6.2.2.2 "Query Component":

Parameters with multiplicity ‘0..n’, may occur multiple times in the query-string in the form of = value. For example, if the resourceType element of the Filter Criteria parameter is represented by a list of 3 values ‘2 3 4’ (see clause 6.3.4.7 in TS-0004 [3]), it would be mapped to ty=2+3+4 in the query-string. At the receiver side, this query string can be reverted back into the list type of representation. The same representation shall be applied for multiple occurrences of contentType and labels elements.

(( IMHO this encoding of multiple-valued parameters is much less desirable than the one used by browsers to transmit multi-select

this code doesn't support the key=value1+value2 encoding: /id-in?fu=1&rcn=8&ty=28+52 returns

{}

whereas /id-in?fu=1&rcn=8&ty=28&ty=52 returns
