Parse SOAP in Go

问题

我刚开始学习Go语言。我想解析一个SOAP服务。我在解析XML时遇到了困难。以下是XML的内容：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
 
  <SOAP-ENV:Header xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <wsse:Security soap:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <wsse:UsernameToken>
        <wsse:Username>USERNAME</wsse:Username>
        <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">SECRET</wsse:Password>
      </wsse:UsernameToken>
    </wsse:Security>
  </SOAP-ENV:Header>
 
  <SOAP-ENV:Body xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <OTA_HotelAvailNotifRQ xmlns="http://www.opentravel.org/OTA/2003/05" EchoToken="abc123" Version="1.0" TimeStamp="2005-08-01T09:30:47+08:00">
      <AvailStatusMessages HotelCode="HOTEL">
        <AvailStatusMessage BookingLimit="10">
          <StatusApplicationControl Start="2010-01-01" End="2010-01-14" InvTypeCode="A1K" RatePlanCode="GLD"/>
        </AvailStatusMessage>
      </AvailStatusMessages>
    </OTA_HotelAvailNotifRQ>
  </SOAP-ENV:Body>
 
</SOAP-ENV:Envelope>

以下是我编写的用于解析XML的代码：

package main

import (
    "fmt"
    "encoding/xml"
)

type Envelope struct {
    XMLName xml.Name
    SOAPENV string   `xml:"xmlns:SOAP-ENV,attr"`
    XSD     string   `xml:"xmlns:xsd,attr"`
    XSI     string   `xml:"xmlns:xsi,attr"`
    SOAPENC string   `xml:"xmlns:SOAP-ENC,attr"`
    NS9132  string   `xml:"xmlns:ns9132,attr"`
    Header  Header   `xml:"SOAP-ENV:Header"`
}

type Header struct {
    XMLName  xml.Name `xml:"SOAP-ENV:Header"`
    Security Security `xml:"wsse:Security"`
}

type Security struct {
    XMLName        xml.Name `xml:"wsse:Security"`
    MustUnderstand string `xml:"soap:mustUnderstand,attr"`
    WSSE           string `xml:"xmlns:wsse,attr"`
    SOAP           string `xml:"xmlns:soap,attr"`
    UsernameToken struct {
        XMLName  xml.Name `xml:"wsse:UsernameToken"`
        Username string `xml:"wsse:Username"`
        Password string `xml:"wsse:Password"`
    }
}

func main() {

    Soap := []byte(`<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
 
  <SOAP-ENV:Header xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <wsse:Security soap:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <wsse:UsernameToken>
        <wsse:Username>USERNAME</wsse:Username>
        <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">SECRET</wsse:Password>
      </wsse:UsernameToken>
    </wsse:Security>
  </SOAP-ENV:Header>
 
  <SOAP-ENV:Body xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <OTA_HotelAvailNotifRQ xmlns="http://www.opentravel.org/OTA/2003/05" EchoToken="abc123" Version="1.0" TimeStamp="2005-08-01T09:30:47+08:00">
      <AvailStatusMessages HotelCode="HOTEL">
        <AvailStatusMessage BookingLimit="10">
          <StatusApplicationControl Start="2010-01-01" End="2010-01-14" InvTypeCode="A1K" RatePlanCode="GLD"/>
        </AvailStatusMessage>
      </AvailStatusMessages>
    </OTA_HotelAvailNotifRQ>
  </SOAP-ENV:Body>
 
</SOAP-ENV:Envelope>`)

    res := &Envelope{}
    err := xml.Unmarshal(Soap, res)

    fmt.Println(res.Header.Security.UsernameToken.Username, err)
}

为什么返回nil？我期望从中获取用户名。另外，为什么我不能在Envelope结构体上使用xml:"SOAP-ENV:Envelope"作为XMLName？错误消息是expected element type <SOAP-ENV:Envelope> but have <Envelope>。

我的Go版本是1.8.3。

英文:

I just started learning Go. I want to parse a SOAP service. I have difficulty parsing the XML. Here's the XML:

&lt;SOAP-ENV:Envelope xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
 
  &lt;SOAP-ENV:Header xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
    &lt;wsse:Security soap:mustUnderstand=&quot;1&quot; xmlns:wsse=&quot;http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd&quot; xmlns:soap=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
      &lt;wsse:UsernameToken&gt;
        &lt;wsse:Username&gt;USERNAME&lt;/wsse:Username&gt;
        &lt;wsse:Password Type=&quot;http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText&quot;&gt;SECRET&lt;/wsse:Password&gt;
      &lt;/wsse:UsernameToken&gt;
    &lt;/wsse:Security&gt;
  &lt;/SOAP-ENV:Header&gt;
 
  &lt;SOAP-ENV:Body xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
    &lt;OTA_HotelAvailNotifRQ xmlns=&quot;http://www.opentravel.org/OTA/2003/05&quot; EchoToken=&quot;abc123&quot; Version=&quot;1.0&quot; TimeStamp=&quot;2005-08-01T09:30:47+08:00&quot;&gt;
      &lt;AvailStatusMessages HotelCode=&quot;HOTEL&quot;&gt;
        &lt;AvailStatusMessage BookingLimit=&quot;10&quot;&gt;
          &lt;StatusApplicationControl Start=&quot;2010-01-01&quot; End=&quot;2010-01-14&quot; InvTypeCode=&quot;A1K&quot; RatePlanCode=&quot;GLD&quot;/&gt;
        &lt;/AvailStatusMessage&gt;
      &lt;/AvailStatusMessages&gt;
    &lt;/OTA_HotelAvailNotifRQ&gt;
  &lt;/SOAP-ENV:Body&gt;
 
&lt;/SOAP-ENV:Envelope&gt;

And here's the code I write to parse the XML:

package main

import (
    &quot;fmt&quot;
    &quot;encoding/xml&quot;
)

type Envelope struct {
	XMLName xml.Name
	SOAPENV string   `xml:&quot;xmlns:SOAP-ENV,attr&quot;`
	XSD     string   `xml:&quot;xmlns:xsd,attr&quot;`
	XSI     string   `xml:&quot;xmlns:xsi,attr&quot;`
	SOAPENC string   `xml:&quot;xmlns:SOAP-ENC,attr&quot;`
	NS9132  string   `xml:&quot;xmlns:ns9132,attr&quot;`
	Header  Header   `xml:&quot;SOAP-ENV:Header&quot;`
}

type Header struct {
	XMLName  xml.Name `xml:&quot;SOAP-ENV:Header&quot;`
	Security Security `xml:&quot;wsse:Security&quot;`
}

type Security struct {
	XMLName        xml.Name `xml:&quot;wsse:Security&quot;`
	MustUnderstand string `xml:&quot;soap:mustUnderstand,attr&quot;`
	WSSE           string `xml:&quot;xmlns:wsse,attr&quot;`
	SOAP           string `xml:&quot;xmlns:soap,attr&quot;`
	UsernameToken struct {
		XMLName  xml.Name `xml:&quot;wsse:UsernameToken&quot;`
		Username string `xml:&quot;wsse:Username&quot;`
		Password string `xml:&quot;wsse:Password&quot;`
	}
}

func main() {

	Soap := []byte(`&lt;SOAP-ENV:Envelope xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
 
  &lt;SOAP-ENV:Header xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
    &lt;wsse:Security soap:mustUnderstand=&quot;1&quot; xmlns:wsse=&quot;http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd&quot; xmlns:soap=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
      &lt;wsse:UsernameToken&gt;
        &lt;wsse:Username&gt;USERNAME&lt;/wsse:Username&gt;
        &lt;wsse:Password Type=&quot;http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText&quot;&gt;SECRET&lt;/wsse:Password&gt;
      &lt;/wsse:UsernameToken&gt;
    &lt;/wsse:Security&gt;
  &lt;/SOAP-ENV:Header&gt;
 
  &lt;SOAP-ENV:Body xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
    &lt;OTA_HotelAvailNotifRQ xmlns=&quot;http://www.opentravel.org/OTA/2003/05&quot; EchoToken=&quot;abc123&quot; Version=&quot;1.0&quot; TimeStamp=&quot;2005-08-01T09:30:47+08:00&quot;&gt;
      &lt;AvailStatusMessages HotelCode=&quot;HOTEL&quot;&gt;
        &lt;AvailStatusMessage BookingLimit=&quot;10&quot;&gt;
          &lt;StatusApplicationControl Start=&quot;2010-01-01&quot; End=&quot;2010-01-14&quot; InvTypeCode=&quot;A1K&quot; RatePlanCode=&quot;GLD&quot;/&gt;
        &lt;/AvailStatusMessage&gt;
      &lt;/AvailStatusMessages&gt;
    &lt;/OTA_HotelAvailNotifRQ&gt;
  &lt;/SOAP-ENV:Body&gt;
 
&lt;/SOAP-ENV:Envelope&gt;`)

	res := &amp;Envelope{}
	err := xml.Unmarshal(Soap, res)

	fmt.Println(res.Header.Security.UsernameToken.Username, err)
}

Why is it returns nil. I expect to get the username value from it. Also why can't I use xml:&quot;SOAP-ENV:Envelope&quot; for XMLName on Envelop struct? The error message is expected element type &lt;SOAP-ENV:Envelope&gt; but have &lt;Envelope&gt;

My Go version is 1.8.3

只需将以下部分翻译为中文：

只需将xml:&quot;wsse:UsernameToken&quot;替换为xml:&quot;UsernameToken&quot;，将xml:&quot;wsse:Security&quot;替换为xml:&quot;Security&quot;，等等。

package main

import (
	"fmt"
	"encoding/xml"
)

type Envelope struct {
	XMLName xml.Name
	Header  Header
}

type Header struct {
	XMLName  xml.Name `xml:"Header"`
	Security Security `xml:"Security"`
}

type Security struct {
	XMLName        xml.Name `xml:"Security"`
	MustUnderstand string   `xml:"mustUnderstand,attr"`
	WSSE           string   `xml:"wsse,attr"`
	SOAP           string   `xml:"soap,attr"`
	UsernameToken  struct {
		XMLName  xml.Name `xml:"UsernameToken"`
		Username string   `xml:"Username"`
		Password string   `xml:"Password"`
	}
}

func main() {

	Soap := []byte(`<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">

  <SOAP-ENV:Header xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <wsse:Security soap:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <wsse:UsernameToken>
        <wsse:Username>USERNAME</wsse:Username>
        <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">SECRET</wsse:Password>
      </wsse:UsernameToken>
    </wsse:Security>
  </SOAP-ENV:Header>

  <SOAP-ENV:Body xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <OTA_HotelAvailNotifRQ xmlns="http://www.opentravel.org/OTA/2003/05" EchoToken="abc123" Version="1.0" TimeStamp="2005-08-01T09:30:47+08:00">
      <AvailStatusMessages HotelCode="HOTEL">

          <StatusApplicationControl Start="2010-01-01" End="2010-01-14" InvTypeCode="A1K" RatePlanCode="GLD"/>
        </AvailStatusMessage>
      </AvailStatusMessages>
    </OTA_HotelAvailNotifRQ>
  </SOAP-ENV:Body>

</SOAP-ENV:Envelope>`)

	res := &Envelope{}
	err := xml.Unmarshal(Soap, res)

	fmt.Println(res.Header.Security.UsernameToken.Username, err)
}

输出：USERNAME <nil>

英文:

Just use xml:&quot;UsernameToken&quot; instead of xml:&quot;wsse:UsernameToken&quot;, xml:&quot;wsse:Security&quot; -> xml:&quot;Security&quot;, etc.

package main
import (
&quot;fmt&quot;
&quot;encoding/xml&quot;
)
type Envelope struct {
XMLName xml.Name
Header  Header
}
type Header struct {
XMLName  xml.Name `xml:&quot;Header&quot;`
Security Security `xml:&quot;Security&quot;`

type Security struct {
XMLName        xml.Name `xml:&quot;Security&quot;`
MustUnderstand string `xml:&quot;mustUnderstand,attr&quot;`
WSSE           string `xml:&quot;wsse,attr&quot;`
SOAP           string `xml:&quot;soap,attr&quot;`
UsernameToken struct {
XMLName  xml.Name `xml:&quot;UsernameToken&quot;`
Username string `xml:&quot;Username&quot;`
Password string `xml:&quot;Password&quot;`
}
}
func main() {
Soap := []byte(`&lt;SOAP-ENV:Envelope xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
&lt;SOAP-ENV:Header xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;

&lt;wsse:UsernameToken&gt;
&lt;wsse:Username&gt;USERNAME&lt;/wsse:Username&gt;
&lt;wsse:Password Type=&quot;http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText&quot;&gt;SECRET&lt;/wsse:Password&gt;
&lt;/wsse:UsernameToken&gt;
&lt;/wsse:Security&gt;
&lt;/SOAP-ENV:Header&gt;
&lt;SOAP-ENV:Body xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
&lt;OTA_HotelAvailNotifRQ xmlns=&quot;http://www.opentravel.org/OTA/2003/05&quot; EchoToken=&quot;abc123&quot; Version=&quot;1.0&quot; TimeStamp=&quot;2005-08-01T09:30:47+08:00&quot;&gt;

&lt;/AvailStatusMessage&gt;
&lt;/AvailStatusMessages&gt;
&lt;/OTA_HotelAvailNotifRQ&gt;
&lt;/SOAP-ENV:Body&gt;
&lt;/SOAP-ENV:Envelope&gt;`)
res := &amp;Envelope{}
err := xml.Unmarshal(Soap, res)
fmt.Println(res.Header.Security.UsernameToken.Username, err)
}

Output: USERNAME &lt;nil&gt;

这似乎是一个XML问题。BayRinat的答案解决了这个问题。通常情况下，你可以尝试使用一个SOAP库：https://golanglibs.com/top?q=soap

https://github.com/mfenniak/go-soap

https://github.com/justwatchcom/goat

https://github.com/fiorix/wsdl2go
