未收到从 gmail api 发送的电子邮件，但显示在已发送文件夹中

Question

我正在使用gapi 发送gmail。但是如果我将邮件发送给自己，它就不会出现在我的收件箱中。最奇怪的是，它出现在“已发送”文件夹中。`

function sendMessage(email, callback) {
    // Web-safe base64 
    var base64EncodedEmail = btoa(email).replace(/\//g,'_').replace(/\+/g,'-');
    var request = gapi.client.gmail.users.messages.send({
        'userId': 'me',
        'message': {
            'raw': base64EncodedEmail
        }
    });
    request.execute(callback);
}

function send() {
    var var to = 'znlswd@gmail.com',
        subject = 'Hello World',
        content = 'send a Gmail.'

    var email = "From: 'me'\r\n"+
        "To:  "+ to +"\r\n"+
        "Subject: "+subject+"\r\n"+
        "\r\n"+
        content;
    sendMessage(email, function () {
        console.log(arguments);
    });
}

` 控制台信息日志为：

"[? {?  "id": "gapiRpc",?  "result": {?   "id": "1471e09d88000bf7",?   "threadId": "1471e09d88000bf7",?   "labelIds": [?    "SENT"?   ]?  }? }?]?"

我可以在 Gmail 的“已发送”文件夹中看到这封邮件，但我没有在收件箱中收到它。这封邮件在“已发送”文件夹中的原文如下：

send a Gmail.

有谁知道为什么？非常感谢！

编辑：我将 Mime 消息中的“收件人：”更改为另一个邮箱（不是 Gmail），并正确接收邮件。感觉更糊涂了。

编辑：我添加了一个“抄送”：字段，它是： znlswd@gmail.com(myself), 71848140@qq.com, swdpal2014@gmail.com, ezdiary@163.com。所有其他人（Gmail和其他邮箱）都收到了邮件，但我仍然无法收到自己的邮件。

我在ezdiary@163.com收到的原始邮件如下：

send a Gmail.

Answer 1

我自己回答一下问题。首先我尝试使用 messages.insert。但是，如果我将“发件人”设置为与“收件人”（我的电子邮件地址）相同，则邮件仍将仅位于“已发送”文件夹中。正确的方法是使用 message.modify api 在发送的邮件中添加“INBOX”和“UNREAD”标签。

gapi.client.request({
     path: "gmail/v1/users/me/messages/" + messageid + "/modify",
     method: "POST",
     body: "{\"addLabelIds\": [\"UNREAD\",\"INBOX\"]}",
     callback: function() {
         console.log("gmail sent to self");
         return console.log(arguments);
     }
})

“messageid”是指发送 API 返回的 id。
