json.Unmarshal should use json:key_name conversion #6002
Description
What steps will reproduce the problem?
If possible, include a link to a program on play.golang.org.
1. Create JSON byteslice =>
jsonBlob := []byte(`{"foo_bar": "baz"}`)
2. Define struct =>
type Quux struct { FooBar string `json:foo_bar`}
3. Unmarshal into declared Quux =>
var myQuux Quux
err := json.Unmarshal(jsonBlob, &myQuux)
fmt.Println(myQuux)
What is the expected output?
{baz}
What do you see instead?
{ }
Which compiler are you using (5g, 6g, 8g, gccgo)?
6g
Which operating system are you using?
Darwin/OSX
Which version are you using? (run 'go version')
go version go1.1.1 darwin/amd64
Please provide any additional information below.
I expected the struct field's tag value (described here:
http://golang.org/pkg/encoding/json/#Marshal) to work in both Marshal and Unmarshal.
This would help keep my variable names idiomatic, as well as satisfy external
requirements.
