config file xxx, type mismatch for field "xxx", expect "string", actual "string"

[lee86]

Describe the bug
If the field "password" is configured as a string in config.go, when the field "password" is set to a pure number in config.yml, an error will be reported and exit

To Reproduce

1. The config.yml is
   config.yml

   password: 123456

2. The config.go is
   config.go

   type Config struct {
     Password   string   `json:"password"`
   }

3. The main.go is
   main.go

   func main() {
    var sc Config
    conf.MustLoad("etc/config.yml", &sc)
   }

4. The error is

   error: config file config.yml, type mismatch for field "password", expect "string", actual "string"
   

Expected behavior
The field "password" can be parsed correctly

Screenshots

Environments (please complete the following information):

• OS: windows10 ltsc
• go-zero version v1.5.5
• goctl version 1.5.5 windows/amd64

More description

config.yml

password: "123456"

The field "password" can be parsed correctly......

Yes, go-zero's configuration file and configuration-defined fields are similar to strong type matching. The same field is not supported for matching multiple types for the time being.

Fixed, and the error message is now:

type mismatch for field "password", expect "string", actual "number"

As you mentioned, the following is correct to parse 123456 as string.

password: "123456"
