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 mainimport (    "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"    xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"><s:Header>  <a:Action s:mustUnderstand="1">http://schemas.xmlsoap.org/ws/2005/02/trust/RST/Issue</a:Action>  <a:ReplyTo>    <a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>  </a:ReplyTo>  <a:To s:mustUnderstand="1">https://login.microsoftonline.com/extSTS.srf</a:To>  <o:Security s:mustUnderstand="1"     xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">    <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>    </wsp:AppliesTo>    <t:KeyType>http://schemas.xmlsoap.org/ws/2005/05/identity/NoProofKey</t:KeyType>    <t:RequestType>http://schemas.xmlsoap.org/ws/2005/02/trust/Issue</t:RequestType>    <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：

    Attrs   []xml.Attr `xml:"-"`

您忽略了所有属性。您应该能够执行以下操作：

   ID string `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
