请教一个 XML 序列化问题
<p>我要生成如下 xml 文件</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<svc_init ver="2.0.0">
<sms ver="2.0.0">
<client>
<id>id</id>
<pwd>pwd</pwd>
<serviceid>serviceid</serviceid>
</client>
<sms_info>
<phone>13013001300</phone>
<content>测试</content>
</sms_info>
</sms>
</svc_init>
</code></pre>
<p>代码为</p>
<pre><code>package main
import (
"encoding/xml"
"fmt"
"os"
)
type Client struct {
Id string `xml:"client>id"`
Pwd string `xml:"client>pwd"`
Serviceid string `xml:"client>serviceid"`
}
type Sms_info struct {
Phone string `xml:"sms_info>phone"`
Content string `xml:"sms_info>content"`
}
type Sms struct {
XMLName xml.Name `xml:"sms"`
Ver string `xml:"ver,attr"`
Client
Sms_info
}
type Svc_init struct {
XMLName xml.Name `xml:"svc_init"`
Ver string `xml:"ver,attr"`
Sms
}
func main() {
id := "id"
pwd := "pwd"
serviceid := "serviceid"
client := Client{Id: id, Pwd: pwd, Serviceid: serviceid}
sms_info := Sms_info{Phone: "13013001300", Content: "测试"}
sms := Sms{Ver: "2.0.0", Client: client, Sms_info: sms_info}
v := Svc_init{Ver: "2.0.0", Sms: sms}
fmt.Println(v)
output, _ := xml.MarshalIndent(v, " ", " ")
os.Stdout.Write(output)
}
</code></pre>
<p>运行后生成</p>
<pre><code><svc_init ver="2.0.0">
<client>
<id>id</id>
<pwd>pwd</pwd>
<serviceid>serviceid</serviceid>
</client>
<sms_info>
<phone>13013001300</phone>
<content>测试</content>
</sms_info>
</svc_init>
</code></pre>
<p>可以看到结果的 sms 结构丢失了 但是我直接打印 v 值</p>
<pre><code>{{ } 2.0.0 {{ } 2.0.0 {id pwd serviceid} {13013001300 测试}}}
</code></pre>
<p>可以看到 sms 结构还在 请问为什么会这样，然后如何修复呢，感谢。</p>
