Gmail API回覆 - 不起作用（Google一方面不处理） [英] Gmail API In-Reply-To not working(Google not handling on one side)

问题描述

问题：当通过api发送回复电子邮件时，在接收端，它显示为包含两条电子邮件（接收者端）的线程，但发件人在收件箱中有两个不同的电子邮件，一封邮件发送（发件人方面的问题）。

Problem: When Reply to email is sent via api then in receiver side it is showing as thread that contains two email messages(good on receivers side) but the sender has two different emails one in Inbox and one in Sent Mail(Problem in sender side).

例如：

电子邮件从A发送到B.
再次B发送到A。

Email is sent from A to B. Again B sends to A.

在api中，我在In-Reply-To和References（根据rfc822格式）中提供以前的电子邮件消息，Google正在A侧处理该消息ID，但不在B侧处理。 A在一个线程中接收消息作为两个消息，但在B的帐户中，它显示为Inbox中的两个单独的电子邮件，一个发送。

here in api i am giving the previous email message-id in "In-Reply-To" and "References",(according to rfc822 format) here Google is handling that message-id on the A side but not on B side. A receives the message in a single thread as two messages but in B's account it is showing as two separate emails one in Inbox and one in sent.

Api ：

https://www.googleapis.com/upload/gmail/v1/users/me/messages/send?uploadType=multipart
内容类型：message / rfc822; boundary = foo_bar_baz

https://www.googleapis.com/upload/gmail/v1/users/me/messages/send?uploadType=multipart Content-Type: "message/rfc822; boundary=foo_bar_baz"

请求正文为rfc2822格式

request body is in rfc2822 format

推荐答案

注意到在我的生产应用程序今天。 更改日志并没有说明发生了什么，但是我发现管理主题的新文档中的问题：

Noticed this in my production app today as well. The change log did not give a clue as to what happened, but I found the problem in the new documentation for managing threads:

1. 请求的 threadId 必须在消息或 Draft.Message 您提供您的请求。


2. 必须将参考和回复至头文件符合RFC 2822标准。


3. 主题标题必须匹配。

1. The requested threadId must be specified on the Message or Draft.Message you supply with your request.
2. The References and In-Reply-To headers must be set in compliance with the RFC 2822 standard.
3. The Subject headers must match.

换句话说，需要提供 threadId 。我不知道这是否是一个错误，因为它没有记录在发送消息 - 在同一天更新的文档。

In other words, the threadId needs to be supplied. I don't know if this is a bug or not, since it is not documented in the sending message-documentation that was updated on the same day.

我想回复我的收件箱中的最新消息。让我们得到相关信息：

I want to respond to the latest message in my inbox. Let's get the relevant information:

请求1：

maxResults = 1
fields = messages/id

GET https://www.googleapis.com/gmail/v1/users/me/messages?maxResults=1&fields=messages%2Fid

响应1：

{
 "messages": [
  {
   "id": "15071b210a1ac883",
   "threadId": "15071a4886871a10"
  }
 ]
}

请求2：

format = metadata
metadataHeaders = In-Reply-To,References,Message-ID,Subject
fields = payload/headers

GET https://www.googleapis.com/gmail/v1/users/me/messages/15071b210a1ac883?format=metadata&metadataHeaders=In-Reply-To&metadataHeaders=References&metadataHeaders=Message-ID&metadataHeaders=Subject&fields=payload%2Fheaders

回应：

{
 "payload": {
  "headers": [
   {
    "name": "In-Reply-To",
    "value": "<[e-mail]>"
   },
   {
    "name": "References",
    "value": "<[e-mail]>"
   },
   {
    "name": "Message-ID",
    "value": "<[e-mail]>"
   },
   {
    "name": "Subject",
    "value": "Re: Perculiar"
   }
  ]
 }
}

剩下的是创建一个包含所有这些数据的消息正确的地方：

All that is left is to create a message with all this data in the right places:

请求3：

Content-Type: multipart/related; boundary="foo_bar_baz"

--foo_bar_baz
Content-Type: application/json; charset=UTF-8

}

--foo_bar_baz
