如何将多个唯一命名的 CSV 附件从 GMAIL 导入到 GOOGLESHEETS
How to import multiple uniquely named CSV attachments from GMAIL to GOOGLESHEETS
我想从一封 GMAIL 电子邮件中导入 3 个 CSV 附件。
附件名称如下：
- Sales.csv
- Labor.csv
- ServerPerformance.csv
我相信可以使用以下方法完成一些操作：
var title = attachment.getName();
if (attachment.getContentType() === "text/csv" && title === "Sales.csv") {
但需要一些帮助才能正确执行。
下面是我目前用于根据 GMAIL 标签和 CSV 附件名称导入的脚本，但它只导入第一个附件 (Sales.csv)，所以我想要一个标签"South Loop" 将 3 个单独的附件从一封电子邮件导入到 google 个工作表。
function SLSalesImportFromGmail() {
//gets first(latest) message with set label
var threads = GmailApp.getUserLabelByName('South Loop').getThreads(0,1);
if (threads && threads.length>0) {
var message = threads[0].getMessages()[0];
var attachment = message.getAttachments()[0];
var title = attachment.getName();
// Is the attachment a CSV file
attachment.setContentTypeFromExtension();
if (attachment.getContentType() === "text/csv" && title === "Sales.csv") {
var ss = SpreadsheetApp.getActive();
var sh = ss.getSheetByName("South Loop Sales");
//parses content of csv to array
var dataString = attachment.getDataAsString();
var csvData = CSVToArray(dataString);
// Remember to clear the content of the sheet before importing new data
sh.clearContents().clearFormats();
//pastes array to sheet
var lastRowValue = sh.getLastRow();
for (var i = 0; i < csvData.length; i++) {
sh.getRange(i+lastRowValue+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
}
if( message.getSubject().indexOf('END OF DAY SALES DETAILS') !== -1) {
SLlogTodaysSales();
}
if (attachment.getContentType() === "text/csv" && title === "Labor.csv") {
var ss = SpreadsheetApp.getActive();
var sh = ss.getSheetByName("South Loop Labor");
//parses content of csv to array
var dataString = attachment.getDataAsString();
var csvData = CSVToArray(dataString);
var range = sh.getRange("A:K");
// Remember to clear the content of the sheet before importing new data
range.clear();
//pastes array to sheet
var lastRowValue = sh.getLastRow();
for (var i = 0; i < csvData.length; i++) {
sh.getRange(i+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
}
if( message.getSubject().indexOf('END OF WEEK LABOR DETAILS') !== -1) {
SLlogWeeksLabor();
}
if (attachment.getContentType() === "text/csv" && title === "ServerPerformance.csv") {
var ss = SpreadsheetApp.getActive();
var sh = ss.getSheetByName("South Loop Server Report");
//parses content of csv to array
var dataString = attachment.getDataAsString();
var csvData = CSVToArray(dataString);
var range = sh.getRange("A:M");
// Remember to clear the content of the sheet before importing new data
range.clear();
//pastes array to sheet
var lastRowValue = sh.getLastRow();
for (var i = 0; i < csvData.length; i++) {
sh.getRange(i+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
}
if( message.getSubject().indexOf('END OF DAY') !== -1) {
SLlogTodaysServers()
}
}
}
}
//marks the Gmail message as read, unstars it and deletes it using Gmail API (Filter sets a star)
message.markRead();
message.unstar();
Gmail.Users.Messages.remove("me", message.getId()); // Added
}
}
//The code formats the code so it can be entered into the Google Script
function CSVToArray( strData, strDelimiter ){
// Check to see if the delimiter is defined. If not,
// then default to comma.
strDelimiter = (strDelimiter || ",");
// Create a regular expression to parse the CSV values.
var objPattern = new RegExp(
(
// Delimiters.
"(\" + strDelimiter + "|\r?\n|\r|^)" +
// Quoted fields.
"(?:\"([^\"]*(?:\"\"[^\"]*)*)\"|" +
// Standard fields.
"([^\"\" + strDelimiter + "\r\n]*))"
),
"gi"
);
// Create an array to hold our data. Give the array
// a default empty first row.
var arrData = [[]];
// Create an array to hold our individual pattern
// matching groups.
var arrMatches = null;
// Keep looping over the regular expression matches
// until we can no longer find a match.
while (arrMatches = objPattern.exec( strData )){
// Get the delimiter that was found.
var strMatchedDelimiter = arrMatches[ 1 ];
// Check to see if the given delimiter has a length
// (is not the start of string) and if it matches
// field delimiter. If id does not, then we know
// that this delimiter is a row delimiter.
if (
strMatchedDelimiter.length &&
(strMatchedDelimiter != strDelimiter)
){
// Since we have reached a new row of data,
// add an empty row to our data array.
arrData.push( [] );
}
// Now that we have our delimiter out of the way,
// let's check to see which kind of value we
// captured (quoted or unquoted).
if (arrMatches[ 2 ]){
// We found a quoted value. When we capture
// this value, unescape any double quotes.
var strMatchedValue = arrMatches[ 2 ].replace(
new RegExp( "\"\"", "g" ),
"\""
);
} else {
// We found a non-quoted value.
var strMatchedValue = arrMatches[ 3 ];
}
// Now that we have our value string, let's add
// it to the data array.
arrData[ arrData.length - 1 ].push( strMatchedValue );
}
// Return the parsed data.
return( arrData );
var label = GmailApp.getUserLabelByName("South Loop");
label.deleteLabel();
}
function SLlogTodaysSales() {
var todaysSales = SpreadsheetApp.getActive().getRange('South Loop Sales Log!SLSalesImport');
var logSheet = todaysSales.getSheet();
logSheet.appendRow(
todaysSales.getValues()
.reduce(function(a, b) { return a.concat(b); }) // flatten the 2D array to 1D
);
}
function SLlogWeeksLabor() {
var ss=SpreadsheetApp.getActive();
var sh=ss.getSheetByName('South Loop Labor Log');
var rg=sh.getRange('SLLaborImport');
var vA=rg.getValues();
sh.getRange(sh.getLastRow()+1,1,vA.length,vA[0].length).setValues(vA);
}
function SLlogTodaysServers() {
var ss=SpreadsheetApp.getActive();
var sh=ss.getSheetByName('South Loop Server Log');
var rg=sh.getRange('SLServerReport');
var vA=rg.getValues();
sh.getRange(sh.getLastRow()+1,1,vA.length,vA[0].length).setValues(vA);
}
因此，在查看您的代码时，我没有看到您遍历附件。
你只是得到第一个执着，然后去分析它，而不管其他的。
var attachment = message.getAttachments()[0];
因此，与其这样做，不如使用 getAttachments() 获取所有附件，并进行 for 循环以分析每个附件。
var attachments = message.getAttachments();
for(var i=0; i < attachments.length; i++){
var attachment = attachments[i];
//....
// The rest of your code needs to go inside this for loop
}
您遇到的问题是，由于这条语句 var attachment = message.getAttachments()[0];，您只查看了第一个附件。相反，只需放下 [0] 并循环遍历所有附件。
为了使这一点更清楚，我去掉了这个例子的一堆代码。也请看完我的笔记。
function SLSalesImportFromGmail() {
var ss = SpreadsheetApp.getActive(); // Get the spreadsheet file once
//gets first(latest) message with set label
var threads = GmailApp.getUserLabelByName('South Loop').getThreads(0,1);
if (threads && threads.length > 0) {
var message = threads[0].getMessages()[0];
// Get all of the attachments and loop through them.
var attachments = message.getAttachments();
for (var i = 0; i < attachments.length; i++) {
var attachment = attachments[i];
var title = attachment.getName();
// Is the attachment a CSV file
attachment.setContentTypeFromExtension();
var table = Utilities.parseCsv(attachment.getDataAsString());
if (attachment.getContentType() === "text/csv") {
// Update the specified sheets
// Clears the sheet of values & formatting and inserts the new table
// using the Apps Script built-in CSV parser.
switch (title) {
case "Sales.csv":
ss.getSheetByName("South Loop Sales").getRange("A:M").clear();
ss.getSheetByName("South Loop Sales").getRange(1, 1, table.length, table[0].length).setValues(table);
break;
case "Labor.csv":
ss.getSheetByName("South Loop Labor").getRange("A:M").clear();
ss.getSheetByName("South Loop Labor").getRange(1, 1, table.length, table[0].length).setValues(table);
break;
case "ServerPerformance.csv":
ss.getSheetByName("South Loop Servers").getRange("A:M").clear();
ss.getSheetByName("South Loop Servers").getRange(1, 1, table.length, table[0].length).setValues(table);
break;
}
}
}
if (message.getSubject().indexOf('END OF DAY') !== -1) {
SLlogTodaysSales();
SLlogTodaysServers();
}
if (message.getSubject().indexOf('END OF WEEK') !== -1) {
SLlogTodaysSales();
SLlogTodaysServers();
SLlogWeeksLabor();
}
// Marks the Gmail message as read, unstars it and deletes it using Gmail API (Filter sets a star)
message.markRead();
message.unstar();
Gmail.Users.Messages.remove("me", message.getId()); // Added
}
}
备注：
- 您正在使用自定义
CSVToArray() 函数将 CSV 文件转换为数组，但是 Google 已经使用 Utilities.parseCsv() 提供了一个方法。在大多数情况下应该足够了。
- 没有必要同时调用
clearContents() 和 clearFormats()，因为 clear() 在一个调用中同时调用。
- 我知道您有额外的逻辑（例如 "END OF DAY" 电子邮件以及劳动力和服务器性能的规则略有不同）。如前所述，我删除了所有这些以演示如何循环访问附件。您可以使用 if or switch 语句在脚本中包含该逻辑，而不必使用我编写的
updateSheet() 闭包。
