Is there any way to make json.Unmarshal not accept a case-insensitive match? I receive a JSON with tags such as "e" and "E" and would like to unmarshal the object with tag "e" but ignore the one with "E". Right now the only solution I found was to define a struct containing both tags and then to simply ignore tag "E", but I'm looking for a cleaner solution.
From the official doc:
To unmarshal JSON into a struct, Unmarshal matches incoming object keys to the keys used by Marshal (either the struct field name or its tag), preferring an exact match but also accepting a case-insensitive match.

To parse JSON, we use the Unmarshal() function in package encoding/json to unpack or decode the data from JSON to a struct. Unmarshal parses the JSON-encoded data and stores the result in the value pointed to by v. Note: If v is nil or not a pointer, Unmarshal returns an InvalidUnmarshalError.
JSON is case sensitive to both field names and data. So is N1QL.
Generally, encoding/decoding JSON refers to the process of actually reading/writing the character data to a string or binary form. Marshaling/Unmarshaling refers to the process of mapping JSON types from and to Go data types and primitives.
Unfortunately this is not something currently supported by the standard json library.
According to https://golang.org/pkg/encoding/json/#Unmarshal
Unmarshal matches incoming object keys to the keys used by Marshal (either the struct field name or its tag), preferring an exact match but also accepting a case-insensitive match
There is no way to turn this behaviour off.
