Google GMail API - users.messages.import() 不在收件箱中为什么？答案

【问题标题】：Google GMail API - users.messages.import() not in INBOX Why?Google GMail API - users.messages.import() 不在收件箱中为什么？
【发布时间】：2018-11-06 03:49:30
【问题描述】：

我正在使用 GMAil API 直接导入消息当我查看 GMail 用户帐户（浏览器 GMail 应用程序）时，我可以看到在 All Mails 中收到的消息，但在 INBOX 中看不到

Google GMail API 状态：Users.messages.import()

仅将邮件导入此用户的邮箱，使用标准的电子邮件递送扫描和分类，类似于通过 SMTP 接收。不发消息

当邮件在那里放置时，我无法从 Mail.app (OSX) 或 Outlook (MS) 中获取它，因为它不被视为新邮件......这是真的吗？无论如何要解决这个问题？

这是我用来导入新消息的函数

        unction gMailInserMessage (sender_name, sender_email, msg_text) {

      // Create a new JWT client using the key file downloaded from the Google Developer Console
      const jwtClient = new google.auth.JWT(
        postoffice_key.client_email,
        null,
        postoffice_key.private_key,
        _.values(config_key.scopes.postoffice),
        config_key.contact_email // subject (or sub) impersonated user
      );

      return jwtClient.authorize().then(tokens => {
          // Obtain a new gmail client, making sure we pass along the auth client
          const gmail = google.gmail({
            version: 'v1',
            auth: jwtClient
           });

          const subject = '???? CONTACT ????';
          const utf8Subject = `=?utf-8?B?${Buffer.from(subject).toString('base64')}?=`;
          const messageParts = [
            'From: ' + sender_name + '<' + sender_email + '>',
            'To: Contact Box <' + config_key.contact_email + '>',
            'Content-Type: text/html; charset=utf-8',
            `Subject: ${utf8Subject}`,
            '',
            'A new contact message just to say hello.',
            'So... <b>Hello!</b>  ????❤️????'
          ];
          const message = messageParts.join('\n');

          // The body needs to be base64url encoded.
          const encodedMessage = Buffer.from(message)
          .toString('base64')
          .replace(/\+/g, '-')
          .replace(/\//g, '_')
          .replace(/=+$/, '');

          //Make an authorized request to import a User Messages
          return gmail.users.messages.import({
            userId: 'me',
            resource: {
              raw: encodedMessage
            }
          });
      }).then(res => {
        // console.log('RES: ', res)
        return res.data;
      });
    }

这是我从请求中得到的回复

              statusText: 'OK',

【问题讨论】：

看来我需要添加 'MIME-Version: 1.0' 标头...在这种情况下，响应是：{"status":200,"infos":{"id": "163a1758e7d02ed2","threadId":"163a1758e7d02ed2","labelIds":["UNREAD","SENT","INBOX"]}}....
但我既没有收到发件人姓名，也没有收到收件人姓名：即使使用“发件人：”+发件人名称+“”，“收件人：联系人框',... 为什么？
是的......就是这样......我正在检查为什么 From: name 不显示（仅获取发件人电子邮件地址）与 To: 相同......
现在就知道了...当显示名称包含空格字符时需要引用它会发布完整功能作为答案

【解决方案1】：

解决了在尝试使用 Firebase 功能处理网站联系表单时出现的所有问题。

1 - 使用 GCP，在我的 Firebase 项目中，我创建了一个名为“邮局”的服务帐户，具有域范围授权，将 JSON 格式的凭据下载到函数/postoffice-key.json 2 - 我为项目启用了 GMail API 3 - 我在另一个函数/config-key.json 中处理范围和电子邮件地址

4- 在我的 GSuite 管理控制台（安全>高级设置>管理 API 客户端访问）中，我从 postoffice-key.json 文件中添加了具有授权范围的 clientId

5 - 我写了一个新的 Firebase HTTPS 函数：newContactMessage()

    const functions = require('firebase-functions');
    const admin = require('firebase-admin');
    admin.initializeApp();

    const { google } = require('googleapis');
    const path = require('path');
    const _ = require('lodash');

    var Buffer = require('buffer/').Buffer  // note: the trailing slash is important!

    // KEY FILES
    const postoffice_key = require('./postoffice-key.json');
    const config_key = require('./config-key.json');

    function gMailInsertContactMessage (sender_name, sender_email, msg_text) {

      // Create a new JWT client using the key file downloaded from the Google Developer Console
      const jwtClient = new google.auth.JWT(
        postoffice_key.client_email,
        null,
        postoffice_key.private_key,
        _.values(config_key.scopes.postoffice),
        config_key.admin_email // subject (or sub) impersonated user
      );

      return jwtClient.authorize().then(tokens => {
          // Obtain a new gmail client, making sure we pass along the auth client
          const gmail = google.gmail({
            version: 'v1',
            auth: jwtClient
           });

          const subject = '? CONTACT ?';
          const utf8Subject = `=?utf-8?B?${Buffer.from(subject).toString('base64')}?=`;
          const messageParts = [
            'From: "Administrator" <' + config_key.admin_email + '>',
            'To: "Contact Box" <' + config_key.contact_email + '>',
            'Reply-To: "' + sender_name + '" <' + sender_email + '>',
            'Content-Type: text/html; charset=utf-8',
            'MIME-Version: 1.0',
            `Subject: ${utf8Subject}`,
            '',
            '<h2>MESSAGE</h2>',
            '<p>' + msg_text + '</p>'
          ];
          const message = messageParts.join('\n');

          // The body needs to be base64url encoded.
          const encodedMessage = Buffer.from(message)
          .toString('base64')
          .replace(/\+/g, '-')
          .replace(/\//g, '_')
          .replace(/=+$/, '');

          //Make an authorized request to import a User Messages
          return gmail.users.messages.send({
            userId: 'me',
            resource: {
              raw: encodedMessage
            }
          });
      }).then(res => {
        // console.log('RES: ', res)
        return res.data;
      });
    }

    // FIREBASE HTTP FUNCTIONS ==================

    exports.newContactMessage = functions.https.onRequest((req, res) => {
      const sender_name = 'Mrs Jenny Doe'
      const sender_email = 'jenny.doe@example.com'
      const sender_msg = 'Hello, how are you overthere ?'
      gMailInsertContactMessage(sender_name, sender_email, sender_msg).then((res) => {
        return { status: 200, infos: res };
      }, error => {
        return {status: error.status, infos: error.message};
      }).then(response => {
        return res.send(response);
      }).catch(console.error);
    });

测试请求：

curl -v https://us-central1-myproject.cloudfunctions.net/newContactMessage

Firebase 函数返回：

{"status":200,"infos"
{"id":"163a5738080e3ee9","threadId":"163a5738080e3ee9","labelIds":["SENT"]}}

在我计算机上的 Mail.app 中，我可以看到 From: 作为项目所有者 ( Administrator ) To: 作为联系人框 (contact@mysite.org 和 Reply-To: 作为联系表发件人电子邮件...容易回复..！以及消息内容！

希望对您有所帮助...（我应该编辑问题标题吗？）
