encoding/json: doesn't deserialize json fields with underscores into struct's fields who's tag contains the underscore but the struct field name does not

This issue - #9841

Is true for go1.14.2

This works

Ws_Id              string.   `json:"ws_id"`

This does not work

WsId              string.   `json:"ws_id"`

Is it fixed in a later version or has all new manufacturing stopped LOL.

@andrewhodel Could you please provide an example of your issue? The following code works well for me:

package main

import (
	"encoding/json"
	"fmt"
)

type Foo struct {
	Ws_Id string `json:"ws_id"`
}

type Bar struct {
	WsId string `json:"ws_id"`
}

func main() {
	js := []byte(`{"ws_id": "abc"}`)

	var f Foo
	var b Bar
	json.Unmarshal(js, &f)
	json.Unmarshal(js, &b)
	fmt.Printf("f: %+v\n", f)
	fmt.Printf("b: %+v\n", b)
}

Output:

$ go1.14.2 run main.go 
f: {Ws_Id:abc}
b: {WsId:abc}

Alternatively, see the playground:

I'm not sure I understand the comment about manufacturing.

The manufacturing comment was a joke about not fixing bugs and having fancy new cars. It must be a mongo issue, I was experiencing the problem with a .Decode() result from find() in the Go Mongo driver. I searched for the issue and found the closed issue with no explanation.
