javascript - 谷歌文档应用程序脚本函数调用非常慢
问题描述
我正在编写一个谷歌文档应用程序脚本来制作谷歌文档插件。当用户单击侧边栏中的按钮时,应用程序脚本函数称为命名executeSpellChecking
。此应用程序脚本函数在获取文档文本后进行远程 POST 调用。
total time
= 从用户单击按钮到 的时间.withSuccessHandler(
,这意味着直到executeSpellChecking
返回 = 2000 毫秒
function time
=executeSpellChecking
调用从开始到结束所用的时间 = 1400 毫秒
t3 = 完成远程 POST 调用所需的时间 = 800ms
t4 = 在 VB.NET 应用程序中完成相同的远程 POST 调用所需的时间 = 200 毫秒
问题:
为什么total time to complete
比total function time
惊人的 600 毫秒大,那里还会发生什么?他们不应该是平等的吗?我该如何改进它?
为什么t3
大于t4
?他们不应该是平等的吗?从 .gs 发生的 POST 请求有问题吗?我该如何改进它?
代码是(sidebar.html):
function runSpellChecking() {
gb_IsSpellcheckingRunning = true;
//gb_isAutoCorrecting = false;
gi_CorrectionCurrWordIndex = -1;
$("#btnStartCorr").attr("disabled", true);
$("#divMistakes").html("");
this.disabled = true;
//$('#error').remove();
var origin = $('input[name=origin]:checked').val();
var dest = $('input[name=dest]:checked').val();
var savePrefs = $('#save-prefs').is(':checked');
//var t1 = new Date().getTime();
console.time("total time");
google.script.run
.withSuccessHandler(
function(textAndTranslation, element) {
if (gb_IsSpellCheckingEnabled) {
console.timeEnd("total time");
//var t2 = new Date().getTime();
go_TextAndTranslation = JSON.parse(JSON.stringify(textAndTranslation));
var pagewords = textAndTranslation.pagewords;
var spellchecked = textAndTranslation.spellchecked;
//alert("total time to complete:" + (t2-t1) + "###" + go_TextAndTranslation.time);
//irrelevant code follows below...
}
})
.withFailureHandler(
function(msg, element) {
showError(msg, $('#button-bar'));
element.disabled = false;
})
.withUserObject(this)
.executeSpellChecking(origin, dest, savePrefs);
}
调用的函数代码是(spellcheck.gs):
function executeSpellChecking(origin, dest, savePrefs) {
//var t1 = new Date().getTime();
console.time("function time");
var body = DocumentApp.getActiveDocument().getBody();
var alltext = body.getText();
var lastchar = alltext.slice(-1);
if (lastchar != " " && lastchar != "\n") {
body.editAsText().insertText(alltext.length, "\n");
alltext = body.getText();
}
var arr_alltext = alltext.split(/[\s\n]/);
var pagewords = new Object;
var pagewordsOrig = new Object;
var pagewordsOrigOffset = new Object;
var offset = 0;
var curWord = "";
var cnt = 0;
for (var i = 0; i < arr_alltext.length; i++) {
curWord = arr_alltext[i];
if (StringHasSimeioStiksis(curWord)) {
curWord = replaceSimeiaStiksis(curWord);
var arr3 = curWord.split(" ");
for (var k = 0; k < arr3.length; k++) {
curWord = arr3[k];
pagewords["" + (cnt+1).toString()] = curWord.replace(/[`~@#$%^&*()_|+\-="<>\{\}\[\]\\\/]/gi, '');
pagewordsOrig["" + (cnt+1).toString()] = curWord;
pagewordsOrigOffset["" + (cnt+1).toString()] = offset;
offset += curWord.length;
cnt++;
}
offset++;
} else {
pagewords["" + (cnt+1).toString()] = curWord.replace(/[`~@#$%^&*()_|+\-="<>\{\}\[\]\\\/\n]/gi, '');
pagewordsOrig["" + (cnt+1).toString()] = curWord;
pagewordsOrigOffset["" + (cnt+1).toString()] = offset;
offset += curWord.length + 1;
cnt++;
}
}
var respTString = "";
var url = 'https://www.example.org/spellchecker.php';
var data = {
"Text" : JSON.stringify(pagewords),
"idOffset" : "0",
"lexID" : "8",
"userEmail" : "test@example.org"
};
var payload = JSON.stringify(data);
var options = {
"method" : "POST",
"contentType" : "application/json",
"payload" : payload
};
//var t11 = new Date().getTime();
console.time("POST time");
var response = UrlFetchApp.fetch(url, options);
console.timeEnd("POST time");
//var t22 = new Date().getTime();
var resp = response.getContentText();
respTString = resp;
var spellchecked = JSON.parse(respTString);
var style = {};
for (var k in pagewords){
if (pagewords.hasOwnProperty(k)) {
if (spellchecked.hasOwnProperty(k)) {
if (spellchecked[k].substr(0, 1) == "1") {
style[DocumentApp.Attribute.FOREGROUND_COLOR] = "#000000";
}
if (spellchecked[k].substr(0, 1) == "0") {
style[DocumentApp.Attribute.FOREGROUND_COLOR] = "#FF0000";
}
if (spellchecked[k].substr(0, 1) == "4") {
style[DocumentApp.Attribute.FOREGROUND_COLOR] = "#0000FF";
}
if (pagewordsOrigOffset[k] < alltext.length) {
body.editAsText().setAttributes(pagewordsOrigOffset[k], pagewordsOrigOffset[k] + pagewordsOrig[k].length, style);
}
}
}
}
//var t2 = new Date().getTime();
console.timeEnd("function time")
return {
"pagewords" : pagewords,
"pagewordsOrig" : pagewordsOrig,
"pagewordsOrigOffset" : pagewordsOrigOffset,
"spellchecked" : spellchecked
}
}
预先感谢您的任何帮助。
编辑:我根据建议更新了代码以使用 console.time ,结果是:
total time: 2048.001953125 ms
Jun 21, 2021, 3:01:40 PM Debug POST time: 809ms
Jun 21, 2021, 3:01:41 PM Debug function time: 1408ms
所以问题不在于如何测量时间。函数时间是 1400 毫秒,而返回时间是 2000 毫秒,相差 600 毫秒,POST 时间是惊人的 800 毫秒,而不是在 VB.net 中进行完全相同的 POST 调用需要 200 毫秒。
解决方案
使用 console.time() 和 console.timeEnd(): https ://developers.google.com/apps-script/reference/base/console
我为你修改了代码。console.timeEnd() 会自动在控制台中输出持续时间,因此我为您删除了显示时差的警报。
您可能希望我用作参数的字符串作为某种常量变量,因此没有使用两次的魔术字符串。我希望这对你有用。
