英文:
Gmail API shows empty body when getting message
问题
当我发送请求以获取电子邮件正文时，Gmail API返回的负载对象上除了正文数据之外的所有内容。
到目前为止，我尝试过以下方法：
- “Watch”方法已经实现并且正常工作。
- 如您在屏幕截图中所见，响应显示了“snipped”，这意味着消息获取是有效的，但正文数据和“raw”字段仍为空。
- 我正确使用了历史ID（将当前ID保存以供后续请求使用）。
- 将所有依赖项升级到最新的稳定版本。
我有什么遗漏吗？
func GetEmail(srv *gmail.Service, historyId uint64) (string, string) {
hist := getHistory(srv, historyId)
for _, h := range hist.History {
for _, m := range h.MessagesAdded {
id := m.Message.Id
mailContent, err := srv.Users.Messages.Get("me", id).Format("full").Do()
if err != nil {
log.Println("error when getting mail content: ", err)
}
if mailContent != nil {
if mailContent.Payload != nil {
payload := mailContent.Payload.Body
data, err := b64.RawURLEncoding.DecodeString(payload.Data)
if err != nil {
log.Println("error b64 decoding: ", err)
}
body := string(data)
if len(body) > 0 {
subject := getSubject(mailContent)
log.Println("subject ", subject)
return body, subject
}
}
}
}
}
return "No email to process, something's wrong - GetEmail func", ""
}
英文:
When I send a request to get the email body, the Gmail API returns everything but the body data on the payload object.
Things I've tried so far
- The "Watch" method is already implemented and working fine
- As you can see from the screenshot, the response shows the "snipped", which means that the message get is working, but the body data and the "raw" field is still empty.
- I am using the history id correctly (saving the current one to use for subsequent requests)
- upgrade all the dependencies to the latest stable version
Am I missing anything?
func GetEmail(srv *gmail.Service, historyId uint64) (string, string) {
hist := getHistory(srv, historyId)
for _, h := range hist.History {
for _, m := range h.MessagesAdded {
id := m.Message.Id
mailContent, err := srv.Users.Messages.Get("me", id).Format("full").Do()
if err != nil {
log.Println("error when getting mail content: ", err)
}
if mailContent != nil {
if mailContent.Payload != nil {
payload := mailContent.Payload.Body
data, err := b64.RawURLEncoding.DecodeString(payload.Data)
if err != nil {
log.Println("error b64 decoding: ", err)
}
body := string(data)
if len(body) > 0 {
subject := getSubject(mailContent)
log.Println("subject ", subject)
return body, subject
}
}
}
}
}
return "No email to process, something's wrong - GetEmail func", ""
}

如果你想要原始的消息数据，你需要使用Format("RAW")。
func GetEmail(srv *gmail.Service, messageId string) {
gmailMessageResposne, err := srv.Users.Messages.Get("me", messageId).Format("RAW").Do()
if err != nil {
log.Println("获取邮件内容时出错：", err)
}
if gmailMessageResposne != nil {
decodedData, err := base64.RawURLEncoding.DecodeString(gmailMessageResposne.Raw)
if err != nil {
log.Println("b64解码时出错：", err)
}
fmt.Printf("- %s\n", decodedData)
}
}
好问题，很有趣 😁
英文:
If you want the RAW message data then you need to use Format("RAW")
func GetEmail(srv *gmail.Service, messageId string) {
gmailMessageResposne, err := srv.Users.Messages.Get("me", messageId).Format("RAW").Do()
if err != nil {
log.Println("error when getting mail content: ", err)
}
if gmailMessageResposne != nil {
decodedData, err := base64.RawURLEncoding.DecodeString(gmailMessageResposne.Raw)
if err != nil {
log.Println("error b64 decoding: ", err)
}
fmt.Printf("- %s\n", decodedData)
}
}
Good question that was fun 😁
