使用https://code.google.com/p/goauth2/
go get code.google.com/p/goauth2/oauth
从Google API控制台获取您的服务电子邮件和p12私钥。目前它无法读取p12文件，因此请使用openssl将其剥离为只包含rsa密钥的文件
openssl pkcs12 -in file.p12 -nocerts -out key.pem -nodes然后删除额外的文本
然后：
package main
import (
"code.google.com/p/goauth2/oauth/jwt"
"flag"
"fmt"
"http"
"io/ioutil"
)
var (
serviceEmail = flag.String("service_email", "", "OAuth service email.")
keyPath = flag.String("key_path", "key.pem", "Path to unencrypted RSA private key file.")
scope = flag.String("scope", "", "Space separated scopes.")
)
func fetchToken() (string, error) {
// 读取私钥的pem文件字节。
keyBytes, err := ioutil.ReadFile(*keyPath)
if err != nil {
return "", err
}
t := jwt.NewToken(*serviceEmail, *scope, keyBytes)
c := &http.Client{}
// 获取访问令牌。
o, err := t.Assert(c)
if err != nil {
return "", err
}
return o.AccessToken, nil
}
func main() {
flag.Parse()
token, err := fetchToken()
if err != nil {
fmt.Printf("ERROR: %v\n", err)
} else {
fmt.Printf("SUCCESS: %v\n", token)
}
}
英文:
Use https://code.google.com/p/goauth2/
go get code.google.com/p/goauth2/oauth
Get your service email and your p12 private key from the Google API Console. For now it can't read p12 files so strip them to just the rsa key with openssl
openssl pkcs12 -in file.p12 -nocerts -out key.pem -nodes then delete the extra text
Then:
package main
import (
"code.google.com/p/goauth2/oauth/jwt"
"flag"
"fmt"
"http"
"io/ioutil"
)
var (
serviceEmail = flag.String("service_email", "", "OAuth service email.")
keyPath = flag.String("key_path", "key.pem", "Path to unencrypted RSA private key file.")
scope = flag.String("scope", "", "Space separated scopes.")
)
func fetchToken() (string, error) {
// Read the pem file bytes for the private key.
keyBytes, err := ioutil.ReadFile(*keyPath)
if err != nil {
return "", err
}
t := jwt.NewToken(*serviceEmail, *scope, keyBytes)
c := &http.Client{}
// Get the access token.
o, err := t.Assert(c)
if err != nil {
return "", err
}
return o.AccessToken, nil
}
func main() {
flag.Parse()
token, err := fetchToken()
if err != nil {
fmt.Printf("ERROR: %v\n", err)
} else {
fmt.Printf("SUCCESS: %v\n", token)
}
