按属性读取 XML

Question

尝试使用 Golang 连接到 MS 共享点，如这里所述，所以我写了下面返回 XML 文本的内容：

package main

import (

    "bytes"

    "encoding/xml"

    "fmt"

    "io/ioutil"

    "log"

    "net/http"

    "strings"

)

func main() {

    const myurl = "https://login.microsoftonline.com/extSTS.srf"

    const username = "[e-mail]"

    const password = "mypassword"

    const endpoint = "https://mydomain.sharepoint.com/"

    const xmlbody = `

    <s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope"

    xmlns:a="http://www.w3.org/2005/08/addressing"

    <o:UsernameToken>

      <o:Username>` + username + `</o:Username>

      <o:Password>` + password + `</o:Password>

    </o:UsernameToken>

  </o:Security>

</s:Header>

<s:Body>

  <t:RequestSecurityToken xmlns:t="http://schemas.xmlsoap.org/ws/2005/02/trust">

    <wsp:AppliesTo xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy">

      <a:EndpointReference>

        <a:Address>` + endpoint + `</a:Address>

      </a:EndpointReference>

    <t:TokenType>urn:oasis:names:tc:SAML:1.0:assertion</t:TokenType>

  </t:RequestSecurityToken>

</s:Body>

</s:Envelope>`

    resp, err := http.Post(myurl, "text/xml", strings.NewReader(xmlbody))

    if err != nil {

        log.Fatal(err)

    }

    defer resp.Body.Close()

    body, _ := ioutil.ReadAll(resp.Body)

    fmt.Println("response Body:", string(body))

}

跟：&nbsp;&nbsp;&nbsp;&nbsp;Attrs&nbsp;&nbsp;&nbsp;[]xml.Attr&nbsp;`xml:"-"`您忽略了所有属性。您应该能够执行以下操作：&nbsp;&nbsp;&nbsp;ID&nbsp;string&nbsp;`xml:"Id,attr"相反，请检查您要查找的ID。您收到该错误，因为它是一个数组。不能将数组与字符串值进行比较。n.Attrs
