Question

我的目标是使用来自JavaScript的Gmail API REST调用的邮件传递系统，所有邮件都不同，邮件列表可以覆盖数千人，因此我无法使用CC字段。我遇到的问题是我在发送操作完成后得到的消息重复。我发送了100条消息，并在接下来的7-20分钟内收到超过120条消息。

function authorize(credentials) {
  var clientSecret = credentials.web.client_secret;
  var clientId = credentials.web.client_id;
  var redirectUrl = {redirect_uri};
  var auth = new googleAuth();
  var oauth2Client = new auth.OAuth2(clientId, clientSecret, redirectUrl);

  fs.readFile(TOKEN_PATH, function(err, token) {
    if (err) {
      getNewToken(oauth2Client, sendMessagePrepair);
    } else {
      oauth2Client.credentials = JSON.parse(token);
      sendMessagePrepair(oauth2Client);
    }
  });
}

function getNewToken(oauth2Client, callback) {
  var authUrl = oauth2Client.generateAuthUrl({
    access_type: 'offline',
    scope: SCOPES
  });
  console.log('Authorize this app by visiting this url: ', authUrl);
  var rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
  });
  rl.question('Enter the code from that page here: ', function(code) {
    rl.close();
    oauth2Client.getToken(code, function(err, token) {
      if (err) {
        console.log('Error while trying to retrieve access token', err);
        return;
      }
      oauth2Client.credentials = token;
      storeToken(token);
      callback(oauth2Client);
    });
});


var counter = 0;
var before_counter = 0;
var SEND_COUNT = 100;

function sendM(post_req, callback) {
      timeout = before_counter * 100;
      before_counter++;
      setTimeout(function(){
    post_req.write(JSON.stringify({ "raw": mail }));
    post_req.end();
        }, timeout);
}

function sendMessagePrepair(oauth2Client) {
    var start = new Date().getTime();
     mail = new Buffer("Content-Type: text/html; charset=\"UTF-8\"\n" +
      "MIME-Version: 1.0\n" +
      "From: {From}\n" +
      "To: {To}\n" +
      "Subject: {Subject}\n\n" +
       messages
).toString("base64").replace(/\+/g, '-').replace(/\//g, '_');

    var post_options = {
  hostname: 'www.googleapis.com',
  port: '443',
  path: '/gmail/v1/users/me/messages/send',
  method: 'POST',
  headers: {
    "Authorization": 'Bearer ' + oauth2Client.credentials.access_token,
    "Content-Type" : "application/json"
  }
};

    var post_req = [];
    for(var idx = 0; idx < SEND_COUNT; idx++)
      post_req.push(http.request(post_options, function(res) {
         res.setEncoding('utf8');
         res.on('data', function (chunk) {
         console.log('Response: ' + chunk);
         counter++;
         if(counter == SEND_COUNT)
           process.exit();
  });
}));    

  async.map(post_req, sendM, function(e, r){
          console.log(r);
    });
}

有时我会收到来自Google服务器的“限制已达到”或“BackendError”RetCode，但即便如此，我仍会收到更多电子邮件，然后才会发送。我使用Node.JS Google Client Library获得了相同的行为：

var gmail = google.gmail('v1');
gmail.users.messages.send({....},callback);

BackendError消息：

回复：{“error”：{“errors”：[{ “域名”：“全球”， “reason”：“backendError”， “message”：“Backend Error”}]，“code”：500，“message”：“Backend Error”}}

我的问题是：有人有同样的问题吗？有没有解决方法？我无法在网上找到关于这种行为的任何内容。

Gmail API消息通过REST在多个send API调用上重复
