400 错误。需要收件人地址。卷曲

我将 Gmail API 与curl一起使用。（用户.消息：发送 https://developers.google.com/gmail/api/v1/reference/users/messages/send)

但我收到错误 400，需要收件人地址。

Command

curl -X POST -H "Authorization: Bearer *****" -H "Content-Type:message/rfc822" -d "{'raw':'Encoded Value'}" "https://www.googleapis.com/upload/gmail/v1/users/me/messages/send"

Response

{
   "error": {
     "errors": [
        {
         "domain": "global",
         "reason": "invalidArgument",
         "message": "Recipient address required"
       }
     ],
     "code": 400,
     "message": "Recipient address required"
   }
 }

编码值是由以下 python 脚本创建的。

import base64
from email.mime.text import MIMEText
from email.utils import formatdate

MAIL_FROM = "[email protected] /cdn-cgi/l/email-protection"
MAIL_TO = "[email protected] /cdn-cgi/l/email-protection"

def create_message():
    message = MIMEText("Gmail body: Hello world!")
    message["from"] = MAIL_FROM
    message["to"] = MAIL_TO
    message["subject"] = "gmail api test"
    message["Date"] = formatdate(localtime=True)

    byte_msg = message.as_string().encode(encoding="UTF-8")
    byte_msg_b64encoded = base64.urlsafe_b64encode(byte_msg)
    str_msg_b64encoded = byte_msg_b64encoded.decode(encoding="UTF-8")

    return {"raw": str_msg_b64encoded}

print(create_message())

当消息通过媒体上传请求发送时https://www.googleapis.com/upload/gmail/v1/users/me/messages/send，请求体需要创建如下。我修改了您的 python 脚本来创建请求正文。请证实。

修改后的python脚本：

import base64
from email.mime.text import MIMEText
from email.utils import formatdate

MAIL_FROM = "[email protected] /cdn-cgi/l/email-protection"
MAIL_TO = "[email protected] /cdn-cgi/l/email-protection"


def encode(v):
    byte_msg = v.encode(encoding="UTF-8")
    byte_msg_b64encoded = base64.b64encode(byte_msg)
    return byte_msg_b64encoded.decode(encoding="UTF-8")


def create_message():
    message = "To: " + MAIL_TO + "\n"
    message += "From: " + MAIL_FROM + "\n"
    message += "Subject: =?utf-8?B?" + encode("gmail api test") + "?=\n"
    message += "Date: " + formatdate(localtime=True) + "\n"
    message += "Content-Type: multipart/alternative; boundary=boundaryboundary\n\n"
    message += "--boundaryboundary\n"
    message += "Content-Type: text/plain; charset=UTF-8\n"
    message += "Content-Transfer-Encoding: base64\n\n"
    message += encode("Hello world!") + "\n\n"
    message += "--boundaryboundary"
    return message


print(create_message())

Result :

To: [email protected] /cdn-cgi/l/email-protection
From: [email protected] /cdn-cgi/l/email-protection
Subject: =?utf-8?B?Z21haWwgYXBpIHRlc3Q=?=
Date: Thu, 15 Mar 2018 01:23:45 +0100
Content-Type: multipart/alternative; boundary=boundaryboundary

--boundaryboundary
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: base64

--boundaryboundary

请将以上请求正文作为文本文件保存到文件中。作为示例，文件名是sample.txt.

很重要的一点 ：

这里，请注意文件的“EOF”的位置。请不要在最后一次之后中断--boundaryboundary。如果最后一次之后破裂--boundaryboundary，未收到正文。图像如下。

卷曲命令：

curl -s -X POST \
  -H "Authorization: Bearer *****" \
  -H "Content-Type: message/rfc822" \
  --data-binary "@sample.txt" \
  "https://www.googleapis.com/upload/gmail/v1/users/me/messages/send"

它发帖sample.txt作为二进制数据。

Result :

{
 "id": "#####",
 "threadId": "#####",
 "labelIds": [
  "UNREAD",
  "SENT",
  "INBOX"
 ]
}

Note :

• 这是一个非常简单的示例，因此请根据您的环境进行修改。
• 此答案假设您的访问令牌可用于这种情况。如果发生与访问令牌相关的错误，请检查范围。

如果我误解了你的问题，我很抱歉。
