frame/g: issue g.client will change the header parameters

[wisonlau]

Go version

go version go1.23.0 darwin/amd64

GoFrame version

v2.7.2

Can this bug be reproduced with the latest release?

Option Yes

What did you do?

header := map[string]string{
	"userid":    gconv.String(platform["userId"]),
	"timestamp": nowTime,
	"sign":      md5Sign,
}
data, pErr := g.Client().ContentJson().SetHeaderMap(header).Post(
	ctx,
	platform["url"].(string),
	postData,
)
if pErr != nil {
	panic(pErr)
}
defer data.Close()
data.RawDump()

What did you see happen?

What did you expect to see?

有些第三方网站只支持头部首字母小写的参数,goframe的工具会把我的参数名字转成首字母大写,比如:timestamp这个参数,这个有什么临时的解决方案救急.

// SetHeaderMap sets custom HTTP headers with map.
func (c *Client) SetHeaderMap(m map[string]string) *Client {
for k, v := range m {
c.header[k] = v
}
return c
}

官方库里面的这个方法能不能修改,或者新增一个方法,m map[string]string -> m map[string][]string

暂不支持自定义设置，可以用标准库可以解决

// 创建一个新的 HTTP 请求
req, err := http.NewRequest("POST", "http://httpbin.org/post", bytes.NewBuffer([]byte(`{"key":"value"}`)))
if err != nil {
  fmt.Println("Error creating request:", err)
  return
}
req.Header["user-agent"] = []string{"my-custom-client"}

Custom settings are not supported yet and can be solved using the standard library.

// Create a new HTTP request
req, err := http.NewRequest("POST", "http://httpbin.org/post", bytes.NewBuffer([]byte(`{"key":"value"}`)))
if err != nil {
  fmt.Println("Error creating request:", err)
  return
}
req.Header["user-agent"] = []string{"my-custom-client"}

@wisonlau @hailaz 大家好，

• 首先，在HTTP协议中，规范化的Header Key是首字母大写的，并且使用英文词连接符号-连接多个单词。
• 其次，在goframe的gclient包中，是通过标准库的HTTP Header Set方法来设置的Header，具体源码在这里

  gf/net/gclient/gclient_request.go

  Line 329 in 183395f

  req.Header.Set(k, v)

• 最后，如果实在是想要自定义与众不同的Header，那么可以考虑使用gclient的前置中间件来实现，具体请参考文档 https://goframe.org/pages/viewpage.action?pageId=7301625
• 此外，给你一个示例吧：

package main

import (
	"github.com/gogf/gf/v2/frame/g"
	"github.com/gogf/gf/v2/net/gclient"
	"net/http"
)

func main() {
	c := g.Client()
	c.Use(func(c *gclient.Client, r *http.Request) (resp *gclient.Response, err error) {
		// 注意这里不要使用r.Header.Set方法设置Header，会被标准化转换为规范的Header Key
		r.Header["userid"] = []string{"10000"}
		resp, err = c.Next(r)
		return resp, err
	})
}

@wisonlau @hailaz Hello everyone,

• First of all, in the HTTP protocol, the standardized Header Key is capitalized, and the English word connection symbol - is used to connect multiple words.
• Secondly, in the gclient package of goframe, the Header is set through the HTTP Header Set method of the standard library. The specific source code is here https://github.com/gogf/gf/blob/ 183395f/net/gclient/gclient_request.go#L329
• Finally, if you really want to customize a unique Header, you can consider using the gclient front-end middleware to implement it. For details, please refer to the document https://goframe.org/pages/viewpage.action ?pageId=7301625
• Also, let me give you an example:

package main

import (
"github.com/gogf/gf/v2/frame/g"
"github.com/gogf/gf/v2/net/gclient"
"net/http"
)

func main() {
c := g.Client()
c.Use(func(c *gclient.Client, r *http.Request) (resp *gclient.Response, err error) {
// Be careful not to use the r.Header.Set method to set the Header here. It will be standardized and converted into a standard Header Key.
r.Header["userid"] = []string{"10000"}
resp, err = c.Next(r)
return resp, err
})
}
