Question

当我使用Gmail API发送带附件的邮件时，收件人会收到没有附件的邮件。但奇怪的是： 1：在发件人的已发送文件夹中，我确实看到了附件 2：如果我发送给自己，两条消息都很好（在发送文件夹和收件箱文件夹中） 3：如果我使用带有相同原始消息的GMail SMTP，它可以正常工作 4：如果我使用具有相同原始消息的第三方SMTP，则可以正常工作。

点数1 + 2超级令人费解。

以下是已发送文件夹中原始邮件的来源：

以下是收件人收件箱文件夹中原始邮件的来源：

正如你所看到的，我文字附件的哑剧部分消失了。

以下是消息的生成方式（为清晰起见而剪切）

msg = Mail.new
html_part = Mail::Part.new do
    content_type 'text/html; charset=UTF-8'
    body html_body
end

msg.html_part = html_part

new_text = plan_text
text_part = Mail::Part.new do
    body new_text
end
msg.text_part = text_part

file_paths.each do |file_path|
    msg.add_file(file_path)

    # I also tried like that, same result
    #open(file_path) do |file| 
    #   msg.attachments[file_path] = file.read 
    #end
end
raw_message = msg.to_s

以下是我使用gmail api发送的方式

client = Google::APIClient.new(:application_name => "app", :application_version => "1")

client.authorization.client_id = "someverylongnumbers.apps.googleusercontent.com"
client.authorization.client_secret = "morerandomletters"
client.authorization.access_token = token
client.authorization.scope = [
    "https://www.googleapis.com/auth/gmail.modify"
]

gmail_api = client.discovered_api('gmail', 'v1') # https://www.googleapis.com/auth/gmail.modify

result = client.execute(
    :api_method => gmail_api.users.messages.to_h['gmail.users.messages.send'],
    :parameters => {
        'userId' => "me"
    },
    :body_object => {
        'raw' =>  Base64.urlsafe_encode64(raw_message)
    }
)

这有什么问题？

Gmail API会删除邮件部分
