我正在尝试使用 Gmail API 发送电子邮件。但我得到这个错误
googleapi:错误 403:请求的身份验证范围不足。更多细节:原因:权限不足,消息:权限不足
我认为它可能与配置有关,我也关注了谷歌的 Go 快速入门,这里是 getClient 函数:
func getClient(config *oauth2.Config) *http.Client {
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
tokFile := "token.json"
tok, err := tokenFromFile(tokFile)
if err != nil {
tok = getTokenFromWeb(config)
saveToken(tokFile, tok)
}
return config.Client(context.Background(), tok)
}
这是发送的代码:
case "pass":
templateData := struct {
VerPass string
}{
VerPass: cont1,
}
emailBody, err := parseTemplate("ver.html", templateData)
if err != nil {
fmt.Println("Parse Err")
return false, err
}
var message gmail.Message
emailTo := "To: " + to + "\r\n"
subject := "Subject: " + sub + "\n"
mime := "MIME-version: 1.0;\nContent-Type: text/html; charset=\"UTF-8\";\n\n"
msg := []byte(emailTo + subject + mime + "\n" + emailBody)
message.Raw = base64.URLEncoding.EncodeToString(msg)
// Send the message
fmt.Println("OOOOOYYYYY")
//here is the problem
b, err := ioutil.ReadFile("credentials.json")
if err != nil {
log.Fatalf("Unable to read client secret file: %v", err)
}
// If modifying these scopes, delete your previously saved token.json.
config, err := google.ConfigFromJSON(b, gmail.MailGoogleComScope)
if err != nil {
log.Fatalf("Unable to parse client secret file to config: %v", err)
}
client := getClient(config)
srv, err := gmail.New(client)
if err != nil {
log.Fatalf("Unable to retrieve Gmail client: %v", err)
}
//GmailService
res, err := srv.Users.Messages.Send("me", &message).Do() // change me
if err != nil {
fmt.Println("Res Err")
fmt.Println(err)
return false, err
}
fmt.Println(res)
我试过了for config, err := google.ConfigFromJSON(b, gmail.MailGoogleComScope)
,我试过使用GmailReadonlyScope
and gmail.GmailSendScope
,但我得到了同样的错误。
