Question

我正在尝试使用Gmail-API从用户那里获取所有线程，并通过使用threads.list在该线程中拥有所有消息。在gmail文档中，它指出以下是命中此端点的响应：

{
 "threads": [
   users.threads Resource
 ],
 "nextPageToken": string,
 "resultSizeEstimate": unsigned integer
}

我有一个简单的功能可以实现这个目标

const {google} = require('googleapis');

/**
 * Lists the threads in the user's account.
 *
 * @param {google.auth.OAuth2} auth An authorized OAuth2 client.
 */

export function listThreads(auth,fn) {
    const gmail =  google.gmail({version: 'v1', auth});

    gmail.users.threads.list({
      userId: 'me',
      q: 'to:abc@abc.com '
    }, (err, res) => {
      if (err) throw 'The API returned an error: ' + err;
      
      // fn is a callback used to return data to the handler since
      // the res object is in the callback of thread.list
      fn(res)
    });

  }

以下是我得到的答复（我将实际电子邮件替换为abc并替换了我的令牌以保护隐私）：

{
    "gmail": {
        "config": {
            "url": "https://www.googleapis.com/gmail/v1/users/me/threads?q=to%3Aabc%40abc.com",

            },
            "params": {

                    "snippet": "Hello abc, Attached are the screenshots of my website for the requirements. Please send me an email with all of the information I&#39;m asking for in the forms. For the colors, here is the site to",
                    "historyId": "4759550"
                }
            ],
            "resultSizeEstimate": 1
        },
        "headers": {

            "connection": "close",
            "content-encoding": "gzip",
            "content-type": "application/json; charset=UTF-8",
            "date": "Thu, 20 Aug 2020 01:13:07 GMT",
            "server": "ESF",
            "transfer-encoding": "chunked",
            "vary": "Origin, X-Origin, Referer",
            "x-content-type-options": "nosniff",
            "x-frame-options": "SAMEORIGIN",
            "x-xss-protection": "0"
        },
        "status": 200,
        "statusText": "OK"
    }
}

如您所见，res.data.threads的messages属性完全丢失。我将不胜感激。

谢谢

在这种情况下，为了从每个线程检索所有消息，需要使用“ Users.threads：get”方法。修改脚本后，它如下所示。

修改后的脚本：

const gmail =  google.gmail({version: 'v1', auth});

gmail.users.threads.list(
  {
    userId: "me",
    q: "to:abc@abc.com ",
  },
  (err, res) => {
    if (err) throw "The API returned an error: " + err;
    Promise.all(
      res.data.threads.map(({ id }) => {
        return new Promise((resolve, reject) => {
          gmail.users.threads.get({ userId: "me", id }, (err, res) => {
            if (err) rejects(err);
            resolve(res.data);
          });
        });
      })
    ).then((res) => {
      fn(res);
    });
  }
);

注意：

在此修改后的脚本中，它假定您已经能够使用Gmail API检索电子邮件。
