How to parse Soap Envelope in Golang ?

问题

我是你的中文翻译助手,以下是你要翻译的内容:

我对golang和Soap都不太熟悉,在解析Soap消息时遇到了问题。

  1. 我有一个Soap消息:

    <soap:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
    soap:Body
    <activationPack_completeResponse"http://tempuri.org/">
    <activationPack_completeResult xsi:type="xsd:string">Active</activationPack_completeResult>
    </activationPack_completeResponse>
    </soap:Body>
    </soap:Envelope>

现在我应该如何在golang中解析它们?对于Soap Envelope,我的结构声明应该是什么样的?

我有以下一些结构:

type MyRespEnvelope struct {
    XMLName xml.Name `xml:"http://schemas.xmlsoap.org/soap/envelope/ Envelope"`
    Soap    *Body
}
type Body struct {
    XMLName     xml.Name `xml:"http://schemas.xmlsoap.org/soap/envelope/ Body"`
    GetResponse *ActivationPack_CompleteResponse
}
type ActivationPack_CompleteResponse struct {
    XMLName xml.Name `xml:"activationPack_completeResponse"`
    Id      string   `xml:"xmlns,attr"`
    MyVar   string   `xml:"activationPack_completeResult"`
}

但是我得到了以下错误:

error: expected element <Envelope> in name space http://schemas.xmlsoap.org/soap/envelope/ but have soap*stopped,reason="end-stepping-range",frame={addr="0x0000000000401211",func="main.UnmarshalFirstDitto",args=[{name="data",value="\"\\nNotice: Undefined variable: area in /var/www/nusoap/dittotv.php on line 25\\n\\nNotice: Undefined variable: area in /var/www/nusoap/dittotv.php on line 27\\n\\nNotice: Undefined variable: area in /var/www/nu\"..."}],file="/media/winshare/Golang/WorkSpace/src/DittoTv/ditto.go",fullname="/media/winshare/Golang/WorkSpace/src/DittoTv/ditto.go",line="60"},thread-id="1",stopped-threads="all",core="0"

请问有人可以告诉我如何声明我的结构,以便能够解析Soap消息吗?

英文:

I am new to golang and Soap and having trouble in parsing soap msg.

1.I have an Soap message

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;soap:Envelope SOAP-ENV:encodingStyle=&quot;http://schemas.xmlsoap.org/soap/encoding/&quot; xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot; xmlns:xsd=&quot;http://www.w3.org/2001/XMLSchema&quot; xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot; xmlns:SOAP-ENC=&quot;http://schemas.xmlsoap.org/soap/encoding/&quot;&gt;
&lt;soap:Body&gt;
&lt;activationPack_completeResponse&quot;http://tempuri.org/&quot;&gt;
&lt;activationPack_completeResult xsi:type=&quot;xsd:string&quot;&gt;Active&lt;/activationPack_completeResult&gt;
&lt;/activationPack_completeResponse&gt;
&lt;/soap:Body&gt;
&lt;/soap:Envelope&gt;

Now how should i Unmarshal them in golang what should be my struct declaration for tag Soap Envelope.

I have some structure as below:

type MyRespEnvelope struct {
	XMLName xml.Name `xml:&quot;http://schemas.xmlsoap.org/soap/envelope/ Envelope&quot;`
	Soap    *Body
}
type Body struct {
	XMLName     xml.Name `xml:&quot;http://schemas.xmlsoap.org/soap/envelope/ Body&quot;`
	GetResponse *ActivationPack_CompleteResponse
}
type ActivationPack_CompleteResponse struct {
	XMLName xml.Name `xml:&quot;activationPack_completeResponse&quot;`
	Id      string   `xml:&quot;xmlns,attr&quot;`
	MyVar   string   `xml:&quot;activationPack_completeResult&quot;`
} 

But I am getting error as below:

error: expected element &lt;Envelope&gt; in name space http://schemas.xmlsoap.org/soap/envelope/ but have soap*stopped,reason=&quot;end-stepping-range&quot;,frame={addr=&quot;0x0000000000401211&quot;,func=&quot;main.UnmarshalFirstDitto&quot;,args=[{name=&quot;data&quot;,value=&quot;\&quot;\\nNotice: Undefined variable: area in /var/www/nusoap/dittotv.php on line 25\\n\\nNotice: Undefined variable: area in /var/www/nusoap/dittotv.php on line 27\\n\\nNotice: Undefined variable: area in /var/www/nu\&quot;...&quot;}],file=&quot;/media/winshare/Golang/WorkSpace/src/DittoTv/ditto.go&quot;,fullname=&quot;/media/winshare/Golang/WorkSpace/src/DittoTv/ditto.go&quot;,line=&quot;60&quot;},thread-id=&quot;1&quot;,stopped-threads=&quot;all&quot;,core=&quot;0&quot;

So someone please tell me how should i declare my structure so that i am able to parse the soap message.

你的XML格式不正确,我猜测是复制粘贴出了问题。我已经进行了修正,在第4行将&lt;activationPack_completeResponse&quot;http://tempuri.org/&quot;&gt;改为&lt;activationPack_completeResponse Id=&quot;http://tempuri.org/&quot;&gt;

你的类型定义有问题。在MyRespEnvelope中,你将Body结构体称为Soap。如果没有定义其XML名称,你将无法得到任何结果。一个更简单的修复方法是将名称从Soap改为Body

我不是XML的专家,但我认为你在命名空间方面做错了一些事情。我简化了你的类型定义,这里是一个可工作的示例:http://play.golang.org/p/957GWzfdvN

package main

import "fmt"
import "encoding/xml"

type MyRespEnvelope struct {
	XMLName xml.Name
	Body    Body
}

type Body struct {
	XMLName     xml.Name
	GetResponse completeResponse `xml:"activationPack_completeResponse"`
}

type completeResponse struct {
	XMLName xml.Name `xml:"activationPack_completeResponse"`
	Id      string   `xml:"Id,attr"`
	MyVar   string   `xml:"activationPack_completeResult"`
}

func main() {

	Soap := []byte(`<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
<soap:Body>
<activationPack_completeResponse Id="http://tempuri.org/">
<activationPack_completeResult xsi:type="xsd:string">Active</activationPack_completeResult>
</activationPack_completeResponse>
</soap:Body>
</soap:Envelope>`)

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

	fmt.Println(res.Body, err)
}

注意:在我编写的代码中,我没有使用指向结构体的指针,而是直接使用了结构体本身。你可以根据你的意图和个人偏好使用任何一种方式。

英文:
  1. Your XML was malformed, I assume it's a bad copy-paste. I corrected it, line 4: &lt;activationPack_completeResponse&quot;http://tempuri.org/&quot;&gt; -> &lt;activationPack_completeResponse Id=&quot;http://tempuri.org/&quot;&gt;

  2. Your types were wrong. in MyRespEnvelopeyou call the Body struct Soap. Without defining its xml name you're not going to get anything. An easier fix is to change the name from Soap to Body.

  3. I'm not an expert in XML, but I think you were doing something wrong with namespaces.
    simplifying your types a little, here is a working example: http://play.golang.org/p/957GWzfdvN

     package main
    
     import &quot;fmt&quot;
     import &quot;encoding/xml&quot;
    
     type MyRespEnvelope struct {
     	XMLName xml.Name
     	Body    Body
     }
    
     type Body struct {
     	XMLName     xml.Name
     	GetResponse completeResponse `xml:&quot;activationPack_completeResponse&quot;`
     }
    
     type completeResponse struct {
     	XMLName xml.Name `xml:&quot;activationPack_completeResponse&quot;`
     	Id      string   `xml:&quot;Id,attr&quot;`
     	MyVar   string   `xml:&quot;activationPack_completeResult&quot;`
     }
    
     func main() {
    
     	Soap := []byte(`&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
     &lt;soap:Envelope SOAP-ENV:encodingStyle=&quot;http://schemas.xmlsoap.org/soap/encoding/&quot; xmlns:SOAP-ENV=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot; xmlns:xsd=&quot;http://www.w3.org/2001/XMLSchema&quot; xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot; xmlns:SOAP-ENC=&quot;http://schemas.xmlsoap.org/soap/encoding/&quot;&gt;
     &lt;soap:Body&gt;
     &lt;activationPack_completeResponse Id=&quot;http://tempuri.org/&quot;&gt;
     &lt;activationPack_completeResult xsi:type=&quot;xsd:string&quot;&gt;Active&lt;/activationPack_completeResult&gt;
     &lt;/activationPack_completeResponse&gt;
     &lt;/soap:Body&gt;
     &lt;/soap:Envelope&gt;`)
    
     	res := &amp;MyRespEnvelope{}
     	err := xml.Unmarshal(Soap, res)
    
     	fmt.Println(res.Body, err)
     }
    

    Note: In the code I put together, I don't use pointer to structs but the structs themselves. You can use either depending on how you're intending to use it, and your preferences I guess.
