如果我知道该电子邮件ID，是否可以使用gmail.js获取有关特定电子邮件的信息？

在新窗口中打开电子邮件 gmail：如果我知道它的ID，如何在url中打开发送电子邮件的电子邮件，如果我知道它的ID？

我需要吗？我需要ID，而不是消息ID。要获取电子邮件ID，我需要获取有关所需电子邮件的全部信息。在Gmail API中，您可以使用

“ nofollow noreferrer”> method：用户.messages.get 。

结果您获得ID（以黄色污染）

” a href =“ https://github.com/kartiktalwar/gmail.js/” rel =“ nofollow noreferrer”> gmail.js库？图书馆是Gmail API的包装纸。我知道方法

我认为最好使用官方 google api javascript客户端从Gmail API请求数据。我建议您从 QuickStart

<!DOCTYPE html>
<html>
  <head>
    <title>Gmail API Quickstart</title>
    <meta charset="utf-8" />
  </head>
  <body>
    <p>Gmail API Quickstart</p>

    <!--Add buttons to initiate auth sequence and sign out-->
    <button id="authorize_button" style="display: none;">Authorize</button>
    <button id="signout_button" style="display: none;">Sign Out</button>

    <pre id="content" style="white-space: pre-wrap;"></pre>

    <script type="text/javascript">
      // Client ID and API key from the Developer Console
      var CLIENT_ID = '<YOUR_CLIENT_ID>';
      var API_KEY = '<YOUR_API_KEY>';

      // Array of API discovery doc URLs for APIs used by the quickstart
      var DISCOVERY_DOCS = ["https://www.googleapis.com/discovery/v1/apis/gmail/v1/rest"];

      // Authorization scopes required by the API; multiple scopes can be
      // included, separated by spaces.
      var SCOPES = 'https://www.googleapis.com/auth/gmail.readonly';

      var authorizeButton = document.getElementById('authorize_button');
      var signoutButton = document.getElementById('signout_button');

      /**
       *  On load, called to load the auth2 library and API client library.
       */
      function handleClientLoad() {
        gapi.load('client:auth2', initClient);
      }

      /**

       *  listeners.

          scope: SCOPES
        }).then(function () {
          // Listen for sign-in state changes.
          gapi.auth2.getAuthInstance().isSignedIn.listen(updateSigninStatus);

          // Handle the initial sign-in state.
          updateSigninStatus(gapi.auth2.getAuthInstance().isSignedIn.get());
          authorizeButton.onclick = handleAuthClick;
          signoutButton.onclick = handleSignoutClick;
        }, function(error) {
          appendPre(JSON.stringify(error, null, 2));
        });
      }

      /**
       *  Called when the signed in status changes, to update the UI
       *  appropriately. After a sign-in, the API is called.
       */
      function updateSigninStatus(isSignedIn) {
        if (isSignedIn) {
          authorizeButton.style.display = 'none';
          signoutButton.style.display = 'block';
          listLabels();
        } else {

      }

      function appendPre(message) {

        pre.appendChild(textContent);
      }

      /**

          'userId': 'me'
        }).then(function(response) {
          var labels = response.result.labels;
          appendPre('Labels:');

          if (labels && labels.length > 0) {

      }

I think you would be better off using the official Google api JavaScript client to request data from the Gmail api. I recommend starting with quickstart

<!DOCTYPE html>

  <head>
    <title>Gmail API Quickstart</title>
    <meta charset="utf-8" />
  </head>
  <body>

    <!--Add buttons to initiate auth sequence and sign out-->
    <button id="authorize_button" style="display: none;">Authorize</button>
    <button id="signout_button" style="display: none;">Sign Out</button>

    <pre id="content" style="white-space: pre-wrap;"></pre>

    <script type="text/javascript">
      // Client ID and API key from the Developer Console
      var CLIENT_ID = '<YOUR_CLIENT_ID>';
      var API_KEY = '<YOUR_API_KEY>';

      // Array of API discovery doc URLs for APIs used by the quickstart
      var DISCOVERY_DOCS = ["https://www.googleapis.com/discovery/v1/apis/gmail/v1/rest"];

      // Authorization scopes required by the API; multiple scopes can be
      // included, separated by spaces.
      var SCOPES = 'https://www.googleapis.com/auth/gmail.readonly';

      var authorizeButton = document.getElementById('authorize_button');
      var signoutButton = document.getElementById('signout_button');

      /**
       *  On load, called to load the auth2 library and API client library.
       */
      function handleClientLoad() {
        gapi.load('client:auth2', initClient);

      function appendPre(message) {
        var pre = document.getElementById('content');
        var textContent = document.createTextNode(message + '\n');
        pre.appendChild(textContent);
