[leavest]

Describe the bug A clear and concise description of what the bug is. load yaml config file can not recognize purely numeric strings without quotatio To Reproduce Steps to reproduce the behavior, if applicable:

1. The code is

# config.yaml
Name: 123456
Host: 127.0.0.1
Port: 6370

# main.go
package main

import (
    "flag"
    "fmt"
    "os"

    "github.com/zeromicro/go-zero/core/conf"
    "gopkg.in/yaml.v2"
)

type Config struct {
    Name string `json:",default=123456789" yaml:"Name"`
    Host string `json:",default=0.0.0.0" yaml:"Host"`
    Port int    `yaml:"Port"`
}

var f = flag.String("f", "config.yaml", "config file")

func main() {
    flag.Parse()
    var c1, c2 Config

    // 读取YAML文件
    yamlFile, err := os.ReadFile(*f)
    if err != nil {
        println(err)
        return
    }

    // 解析YAML
    if err = yaml.Unmarshal(yamlFile, &c1); err != nil {
        println(err)
        return
    }
    fmt.Println(c1)

    conf.MustLoad(*f, &c2)
    // conf.MustLoad(*f, &c，conf.UseEnv()) // 额外从环境变量中加载配置
    fmt.Println(c2.Name)
}

2. The error is

 {123456 127.0.0.1 6370}
2024/07/11 19:35:55 error: config file config.yaml, type mismatch for field "name", expect "string", actual "number"
exit status 1

我知道加个引号可以避免这个问题，但是希望load行为向yaml.Unmarshal看齐

I know that adding quotes can avoid this problem, but I hope that the load behavior will be consistent with yaml.Unmarshal

Let me check how to fix it.

We designed it like this is because go-zero handles config files in the same way inspite of yaml, json, toml, properties etc.
