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：

  1. <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  2.  
  3.   <SOAP-ENV:Header xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  4.     <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/">
  5.       <wsse:UsernameToken>
  6.         <wsse:Username>USERNAME</wsse:Username>
  7.         <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">SECRET</wsse:Password>
  8.       </wsse:UsernameToken>
  9.     </wsse:Security>
  10.   </SOAP-ENV:Header>
  11.  
  12.   <SOAP-ENV:Body xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  13.     <OTA_HotelAvailNotifRQ xmlns="http://www.opentravel.org/OTA/2003/05" EchoToken="abc123" Version="1.0" TimeStamp="2005-08-01T09:30:47+08:00">
  14.       <AvailStatusMessages HotelCode="HOTEL">
  15.         <AvailStatusMessage BookingLimit="10">
  16.           <StatusApplicationControl Start="2010-01-01" End="2010-01-14" InvTypeCode="A1K" RatePlanCode="GLD"/>
  17.         </AvailStatusMessage>
  18.       </AvailStatusMessages>
  19.     </OTA_HotelAvailNotifRQ>
  20.   </SOAP-ENV:Body>
  21.  
  22. </SOAP-ENV:Envelope>

以下是我编写的用于解析XML的代码：

  1. package main
  3. import (
  4.     "fmt"
  5.     "encoding/xml"
  6. )
  8. type Envelope struct {

  11.     XSD     string   `xml:"xmlns:xsd,attr"`
  12.     XSI     string   `xml:"xmlns:xsi,attr"`
  13.     SOAPENC string   `xml:"xmlns:SOAP-ENC,attr"`
  14.     NS9132  string   `xml:"xmlns:ns9132,attr"`
  15.     Header  Header   `xml:"SOAP-ENV:Header"`
  16. }
  18. type Header struct {
  19.     XMLName  xml.Name `xml:"SOAP-ENV:Header"`
  20.     Security Security `xml:"wsse:Security"`
  21. }
  23. type Security struct {
  24.     XMLName        xml.Name `xml:"wsse:Security"`
  25.     MustUnderstand string `xml:"soap:mustUnderstand,attr"`
  26.     WSSE           string `xml:"xmlns:wsse,attr"`
  27.     SOAP           string `xml:"xmlns:soap,attr"`
  28.     UsernameToken struct {
  29.         XMLName  xml.Name `xml:"wsse:UsernameToken"`
  30.         Username string `xml:"wsse:Username"`
  31.         Password string `xml:"wsse:Password"`
  32.     }
  33. }
  35. func main() {
  37.     Soap := []byte(`<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  38.  
  39.   <SOAP-ENV:Header xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  40.     <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/">

  44.       </wsse:UsernameToken>
  45.     </wsse:Security>
  46.   </SOAP-ENV:Header>
  47.  
  48.   <SOAP-ENV:Body xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  49.     <OTA_HotelAvailNotifRQ xmlns="http://www.opentravel.org/OTA/2003/05" EchoToken="abc123" Version="1.0" TimeStamp="2005-08-01T09:30:47+08:00">
  50.       <AvailStatusMessages HotelCode="HOTEL">
  51.         <AvailStatusMessage BookingLimit="10">
  52.           <StatusApplicationControl Start="2010-01-01" End="2010-01-14" InvTypeCode="A1K" RatePlanCode="GLD"/>
  53.         </AvailStatusMessage>
  54.       </AvailStatusMessages>
  55.     </OTA_HotelAvailNotifRQ>
  56.   </SOAP-ENV:Body>
  57.  
  58. </SOAP-ENV:Envelope>`)
  60.     res := &Envelope{}
  61.     err := xml.Unmarshal(Soap, res)
  63.     fmt.Println(res.Header.Security.UsernameToken.Username, err)
  64. }

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。

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

  61. 	err := xml.Unmarshal(Soap, res)
  63. 	fmt.Println(res.Header.Security.UsernameToken.Username, err)
  64. }

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;

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。

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.

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

英文:

That seems like an XML problem. BayRinat's answer addresses this issue. Generally, you could try a SOAP library: https://golanglibs.com/top?q=soap
