我无法回答有关 adwords API 的问题,因为我没有看到该公司的公告,并且很难从外部预测发布前的时间。
那么我来回答你的第二个问题。
我不知道 Go 中有任何 SOAP 库(go-lang.cat-v.org http://go-lang.cat-v.org/似乎没有引用一个),但与大多数语言一样,处理简单 SOAP 消息的一种方法是使用基本的http http://golang.org/pkg/net/http/ and xml http://golang.org/pkg/encoding/xml/图书馆。
两个重要的操作是
1) 通过执行 POST 查询来获取答案:
resp, err := httpClient.Post(query, "text/xml; charset=utf-8", someXMLasBytes)
2)使用解码它xml.NewDecoder http://golang.org/pkg/encoding/xml/#NewDecoder进入所需的结构:
parser := xml.NewDecoder(bytes.NewBufferString(in))
err = parser.DecodeElement(&envelope, nil)
以下是用 Go 完成的 SOAP 查询的完整且带注释的示例(由此简化 https://github.com/Canop/Chrall/blob/master/go/src/chrallserver/mhsoapclient.go) :
package main
import (
"bytes"
"encoding/xml"
"fmt"
"io"
"io/ioutil"
"net/http"
"strings"
)
// The URL of the SOAP server
const MH_SOAP_URL = "http://sp.mountyhall.com/SP_WebService.php"
// this is just the message I'll send for interrogation, with placeholders
// for my parameters
const SOAP_VUE_QUERY_FORMAT = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?><SOAP-ENV:Envelope 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:tns=\"urn:SP_WebService\" xmlns:soap=\"http://schemas.xmlsoap.org/wsdl/soap/\" xmlns:wsdl=\"http://schemas.xmlsoap.org/wsdl/\" xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\" ><SOAP-ENV:Body><mns:Vue xmlns:mns=\"uri:mhSp\" SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\"><numero xsi:type=\"xsd:string\">%d</numero><mdp xsi:type=\"xsd:string\">%s</mdp></mns:Vue></SOAP-ENV:Body></SOAP-ENV:Envelope>"
// Here I define Go structures, almost identical to the structure of the
// XML message we'll fetch
// Note that annotations (the string "return>item") allow to have a slightly
// different structure or different namings
type SoapItem struct {
Numero int
Nom string
Type string
PositionX int
PositionY int
PositionN int
Monde int
}
type SoapVue struct {
Items []SoapItem "return>item"
}
type SoapFault struct {
Faultstring string
Detail string
}
type SoapBody struct {
Fault SoapFault
ProfilResponse SoapProfil
VueResponse SoapVue
}
type SoapEnvelope struct {
XMLName xml.Name
Body SoapBody
}
// Here is the function querying the SOAP server
// It returns the whole answer as a Go structure (a SoapEnvelope)
// You could also return an error in a second returned parameter
func GetSoapEnvelope(query string, numero int, mdp string) (envelope *SoapEnvelope) {
soapRequestContent := fmt.Sprintf(query, numero, mdp)
httpClient := new(http.Client)
resp, err := httpClient.Post(MH_SOAP_URL, "text/xml; charset=utf-8", bytes.NewBufferString(soapRequestContent))
if err != nil {
// handle error
}
b, e := ioutil.ReadAll(resp.Body) // probably not efficient, done because the stream isn't always a pure XML stream and I have to fix things (not shown here)
if e != nil {
// handle error
}
in := string(b)
parser := xml.NewDecoder(bytes.NewBufferString(in))
envelope = new(SoapEnvelope) // this allocates the structure in which we'll decode the XML
err = parser.DecodeElement(&envelope, nil)
if err != nil {
// handle error
}
resp.Body.Close()
return
}
