与Golang通话

我是刚来golang的新手，正在尝试与您进行soap通话

我已经生成了wsdl代码并将其作为一个包安装。然而，我正在努力理解从它调用方法的语法

当我检查包时，这就是我想要的soap主体：

type AccountUser struct {
    XMLName xml.Name `xml:"http://exacttarget.com/wsdl/partnerAPI AccountUser"`

    *APIObject

    AccountUserID             int32         `xml:"AccountUserID,omitempty"`
    UserID                    string        `xml:"UserID,omitempty"`
    Password                  string        `xml:"Password,omitempty"`
    Name                      string        `xml:"Name,omitempty"`
    Email                     string        `xml:"Email,omitempty"`
    MustChangePassword        bool          `xml:"MustChangePassword,omitempty"`
    ActiveFlag                bool          `xml:"ActiveFlag,omitempty"`
    ChallengePhrase           string        `xml:"ChallengePhrase,omitempty"`
    ChallengeAnswer           string        `xml:"ChallengeAnswer,omitempty"`
    UserPermissions           []*UserAccess `xml:"UserPermissions,omitempty"`
    Delete                    int32         `xml:"Delete,omitempty"`
    LastSuccessfulLogin       time.Time     `xml:"LastSuccessfulLogin,omitempty"`
    IsAPIUser                 bool          `xml:"IsAPIUser,omitempty"`
    NotificationEmailAddress  string        `xml:"NotificationEmailAddress,omitempty"`
    IsLocked                  bool          `xml:"IsLocked,omitempty"`
    Unlock                    bool          `xml:"Unlock,omitempty"`
    BusinessUnit              int32         `xml:"BusinessUnit,omitempty"`
    DefaultBusinessUnit       int32         `xml:"DefaultBusinessUnit,omitempty"`
    DefaultApplication        string        `xml:"DefaultApplication,omitempty"`
    Locale                    *Locale       `xml:"Locale,omitempty"`
    TimeZone                  *TimeZone     `xml:"TimeZone,omitempty"`
    DefaultBusinessUnitObject *BusinessUnit `xml:"DefaultBusinessUnitObject,omitempty"`

    AssociatedBusinessUnits struct {
        BusinessUnit []*BusinessUnit `xml:"BusinessUnit,omitempty"`
    } `xml:"AssociatedBusinessUnits,omitempty"`

    Roles struct {
        Role []*Role `xml:"Role,omitempty"`
    } `xml:"Roles,omitempty"`

    LanguageLocale *Locale `xml:"LanguageLocale,omitempty"`

    SsoIdentities struct {
        SsoIdentity []*SsoIdentity `xml:"SsoIdentity,omitempty"`
    } `xml:"SsoIdentities,omitempty"`
}

调用SOAP的方法是：

func (s *SOAPClient) Call(soapAction string, request, response interface{}) error {
    envelope := SOAPEnvelope{
    //Header:        SoapHeader{},
    }

    envelope.Body.Content = request
    buffer := new(bytes.Buffer)

    encoder := xml.NewEncoder(buffer)
    //encoder.Indent("  ", "    ")

    if err := encoder.Encode(envelope); err != nil {
        return err
    }

    if err := encoder.Flush(); err != nil {
        return err
    }

    log.Println(buffer.String())

    req, err := http.NewRequest("POST", s.url, buffer)
    if err != nil {
        return err
    }
    if s.auth != nil {
        req.SetBasicAuth(s.auth.Login, s.auth.Password)
    }

    req.Header.Add("Content-Type", "text/xml; charset=\"utf-8\"")
    if soapAction != "" {
        req.Header.Add("SOAPAction", soapAction)
    }

    req.Header.Set("User-Agent", "gowsdl/0.1")
    req.Close = true

    tr := &http.Transport{
        TLSClientConfig: &tls.Config{
            InsecureSkipVerify: s.tls,
        },
        Dial: dialTimeout,
    }

    client := &http.Client{Transport: tr}
    res, err := client.Do(req)
    if err != nil {
        return err
    }
    defer res.Body.Close()

    rawbody, err := ioutil.ReadAll(res.Body)
    if err != nil {
        return err
    }
    if len(rawbody) == 0 {
        log.Println("empty response")
        return nil
    }

    log.Println(string(rawbody))
    respEnvelope := new(SOAPEnvelope)
    respEnvelope.Body = SOAPBody{Content: response}
    err = xml.Unmarshal(rawbody, respEnvelope)
    if err != nil {
        return err
    }

    fault := respEnvelope.Body.Fault
    if fault != nil {
        return fault
    }

    return nil
}

我已经将这个包导入到我的go文件中，并且希望得到关于如何调用它的指针。

要使用生成的代码，您显然必须首先使用生成的“构造函数”函数之一初始化soap客户端

NewSOAPClient

或

newsoapclienttwithtlsconfig

之后，您需要准备两个值，作为

调用

方法的请求和响应参数，它们表示soap请求/响应有效负载的主体内容

这两个值的类型取决于您想要进行的调用类型，例如，假设调用create\u account、update\u account和delete\u account通常需要不同的类型。基本上，

请求

值的类型应该可以封送到与soap服务对指定操作的预期xml相匹配的xml中，而

响应

的类型应该与与与soap服务对指定操作的文档化响应相匹配的xml不可封送

考虑这个人为的例子：

有一个允许您创建用户的SOAP服务。要使用该服务创建用户，您需要发送电子邮件和密码，如果一切正常，它将返回一个id。在这种情况下，您的两种请求/响应类型如下所示：

type CreateUserRequest struct {
    Email    string `xml:"Email,omitempty"`
    Password string `xml:"Password,omitempty"`
}

type CreateUserResponse struct {
    ID string `xml:"ID"`
}

client := NewSOAPClient("https://soap.example.com/call", true, nil)

req := &CreateUserRequest{
    Email:    "jdoe@example.com",
    Password: "1234567890",
}
res := &CreateUserResponse{}
if err := client.Call("create_user", req, res); err != nil {
    panic(err)
}

// if everything went well res.ID should have its
// value set with the one returned by the service.
fmt.Println(res.ID)

然后客户端代码将如下所示：

type CreateUserRequest struct {
    Email    string `xml:"Email,omitempty"`
    Password string `xml:"Password,omitempty"`
}

type CreateUserResponse struct {
    ID string `xml:"ID"`
}

client := NewSOAPClient("https://soap.example.com/call", true, nil)

req := &CreateUserRequest{
    Email:    "jdoe@example.com",
    Password: "1234567890",
}
res := &CreateUserResponse{}
if err := client.Call("create_user", req, res); err != nil {
    panic(err)
}

// if everything went well res.ID should have its
// value set with the one returned by the service.
fmt.Println(res.ID)
