xml - go - 标签中的属性/隐藏父标签 : SOAP envelope

Question

我正在尝试将 Go 结构编码为 Soap-Envelope (xml)。到目前为止，除了一个小错误外，皂体看起来还不错。虽然我的信封应该是这样的:

<SOAP-ENV:Body>
    <q3:WMLS_AddToStore xmlns:q3="http://www.foo.abr/message/120">
        <WMLtypeIn>param1</WMLtypeIn>
        <XMLin>param2</XMLin>
        <OptionsIn>param3</OptionsIn>
        <CapabilitiesIn>param4</CapabilitiesIn>
    </q3:WMLS_AddToStore>
</SOAP-ENV:Body>

我的代码正在生成这个:

<SOAP-ENV:Body>
  <q1:WMLS_AddToStore xmlns:q1="http://www.foo.abr/message/120">
    <ActionName>
      <WMLtypeIn>param1</WMLtypeIn>
      <XMLin>param2</XMLin>
      <OptionsIn>param3</OptionsIn>
      <CapabilitiesIn>param4</CapabilitiesIn>
    </ActionName>
  </q1:WMLS_AddToStore>
</SOAP-ENV:Body>

注意 ActionName 标签。我想:

删除这个 ActionName 标签

或

将其重命名为 q3:WMLS_AddToStore(我可以这样做)，但随后我需要向其添加 xmlns:q1 属性。

代码:

type Message interface{}
type OperationWMLS_AddToStoreSoapIn struct {
WMLtypeIn      string `xml:"WMLtypeIn,omitempty"`
XMLin          string `xml:"XMLin,omitempty"`
OptionsIn      string `xml:"OptionsIn,omitempty"`
CapabilitiesIn string `xml:"CapabilitiesIn,omitempty"`
}

type Body struct {
XMLName    xml.Name     `xml:"SOAP-ENV:Body"`
ActionName temperature `xml:"q1:WMLS_AddToStore"`
}

type Action struct {
ActionName Message `xml:",innerxml"`
XMLAttr    string  `xml:"xmlns:q1,attr"`
}

func main() {
in := struct {
    OperationWMLS_AddToStoreSoapIn `xml:"tns:WMLS_AddToStore"`
}{
    OperationWMLS_AddToStoreSoapIn{
        "WMLtypeIn",
        "XMLin",
        "OptionsIn",
        "CapabilitiesIn",
    },
}

x := &Body{
    ActionName: Action{
        ActionName: in,
        XMLAttr: "http://www.foo.abr/message/120",
        },
    }

enc := xml.NewEncoder(os.Stdout)
enc.Indent("", "  ")
if err := enc.Encode(x); err != nil {
    fmt.Printf("error: %v\n", err)
}

}

您如何看待这样重写您的代码 (https://play.golang.org/p/Kf5VpQeuThx):

package main

import (
    "encoding/xml"
    "fmt"
    "os"
)

type s2 struct {
    XMLName        xml.Name `xml:"q3:WMLS_AddToStore"`
    XMLAttr        string   `xml:"xmlns:q3,attr"`
    WMLtypeIn      string   `xml:"WMLtypeIn,omitempty" json:"WMLtypeIn,omitempty" yaml:"WMLtypeIn,omitempty"`
    XMLin          string   `xml:"XMLin,omitempty" json:"XMLin,omitempty" yaml:"XMLin,omitempty"`
    OptionsIn      string   `xml:"OptionsIn,omitempty" json:"OptionsIn,omitempty" yaml:"OptionsIn,omitempty"`
    CapabilitiesIn string   `xml:"CapabilitiesIn,omitempty" json:"CapabilitiesIn,omitempty" yaml:"CapabilitiesIn,omitempty"`
}

type s1 struct {
    XMLName xml.Name `xml:"SOAP-ENV:Body"`
    S2      s2
}

func main() {
    x := &s1{
        S2: s2{
            XMLAttr:        "http://www.foo.abr/message/120",
            WMLtypeIn:      "WMLtypeIn",
            XMLin:          "XMLin",
            OptionsIn:      "OptionsIn",
            CapabilitiesIn: "CapabilitiesIn",
        },
    }

    enc := xml.NewEncoder(os.Stdout)
    enc.Indent("", "  ")
    if err := enc.Encode(x); err != nil {
        fmt.Printf("error: %v\n", err)
    }
}
