添加标签(标签)方法的"无效参数"错误

Question

一段时间以来，我一直在尝试在Google Apps Script中为Gmail创建一个自动标签器。此脚本解析电子邮件的正文并查找格式为"#DL："的行，提取其后的文本(即日期(，通过我编码的标准化器运行此字符串，计算该日期与现在之间的日期差异，如果紧急，则为其分配颜色。它获取所有这些信息并标记该电子邮件。这是我使用的代码：

var filters = [{
match: /[nr][ t]*#DL:[ t]*([^nr]*)/,
archive: false
}, ];
var from = [];
function labeler() {
var batchSize = 10;
var labelCache = {};
var query = "in:anywhere";
var threads = GmailApp.search(query, 0, batchSize);
GmailApp.getMessagesForThreads(threads);
var findOrCreateLabel = function(name) {
if (labelCache[name] === undefined) {
labelCache[name] = GmailApp.getUserLabelByName(name) || createLabelByGmailApi(name);
}
//GmailApp.createLabel(name);
//createLabelByGmailApi(name);
return labelCache[name];
}
var applyLabel = function(name, thread) {
var label = null;
var labelName = "";
name.split('&').forEach(function(labelPart, i) {
labelName = labelName + (i === 0 ? "" : "&") + labelPart.trim();
label = findOrCreateLabel(labelName);
});
thread.addLabel(label);
}
threads.forEach(function(thread) {
var messages = thread.getMessages();
if (messages == null) return;
var message = messages[messages.length - 1];
var body = message.getRawContent();
var archive = true;
filters.forEach(function(filter) {
var matches = filter.match.exec(body);
if (matches !== null) {
var label = filter.name || matches[1];
var data = datestd(label);
var cor = datecalc(data);
label = "Datas/" + data;
if (label !== undefined) applyLabel(label, thread);
if (filter.archive !== undefined && !filter.archive) archive = false;
}

if (archive) thread.moveToArchive();

要为正在发生的事情提供一些背景信息： 标记器函数从电子邮件中获取字符串，将其发送到 datestd 函数以进行标准化，该输出是标签的名称。该输出还用于通过输出颜色的函数 datecalc 计算该日期与现在之间的日期差。createLabelByGmailApi函数将使用此颜色来创建具有该名称和颜色的标签。在此之后，标记器功能将该标签应用于相关电子邮件。

我正在尝试解决2个问题，但无济于事：

1. 无效参数错误

运行上面的代码时，我在thread.addLabel(label);行中收到"无效参数"错误(参数是标签(，我不知道为什么。

2.似乎无法获取createLabelByGmailApi功能的颜色

由于代码的结构方式，我似乎无法获取函数的颜色，因为这种颜色取决于日期，这取决于电子邮件正文的解析，这在函数的后面发生。我似乎找不到重新排列它的方法，所以我能够为该功能提供一种颜色，如果您能提供帮助，那就太好了。

我知道这是少数，非常感谢您阅读本文，您的帮助将不胜感激。

这个修改怎么样？

似乎您的问题原因是运行Gmail.Users.Labels.create()时没有很快反映板条箱标签。至此，label变得null.为了消除此问题，我在使用Gmail.Users.Labels.create()创建标签时使用Gmail.Users.Threads.modify()添加了标签。请修改如下。

修改后的脚本：

请按如下方式修改labeler()applyLabel()。

从：

var applyLabel = function(name, thread) {
var label = null;
var labelName = "";
name.split('&').forEach(function(labelPart, i) {
labelName = labelName + (i === 0 ? "" : "&") + labelPart.trim();
label = findOrCreateLabel(labelName);
});
thread.addLabel(label);
}

自：

var applyLabel = function(name, thread) {
var label = null;
var labelName = "";
name.split('&').forEach(function(labelPart, i) {
labelName = labelName + (i === 0 ? "" : "&") + labelPart.trim();
label = findOrCreateLabel(labelName);
});
if (typeof label == "string") {
Gmail.Users.Threads.modify({addLabelIds: [label]}, "me", thread.getId());
} else {
thread.addLabel(label);
}
}

并且，请按如下方式修改createLabelByGmailApi()。

从：

Gmail.Users.Labels.create(resource, userId);
return GmailApp.getUserLabelByName(name);

自：

return Gmail.Users.Labels.create(resource, userId).id;

注意：

• 在labelCache[name] = GmailApp.getUserLabelByName(name) || createLabelByGmailApi(name);，当调用createLabelByGmailApi(name)时，name被用作参数。但是在createLabelByGmailApi(name, color)的函数中，name和color被用作参数。我认为在当前情况下，#41236d被用作默认值。请确认这一点。
• 当我看到datestd()的功能时，我注意到使用了includes()。在当前阶段，它不能用于Google Apps Script。那么includes()在其他地方宣布的呢？

如果我误解了你的情况，这不是你想要的方向，我很抱歉。
