我使用time模块将n毫秒转换为秒并将其添加到当前时间。
from flask import Flask
currenttime = int(round(time.time() * 1000))
@app.route('/api/<seconds>')
def api_seconds(seconds):
milliseconds = int(seconds) * 1000
finaltime = int(currenttime + milliseconds)
return 'Seconds: ' + seconds + '<br />' + 'Milliseconds: ' + str(milliseconds) + \
'<br />' + 'Time: ' + str(currenttime) + '<br />' + 'Final Time: ' + str(finaltime)
这会成功返回运行脚本时的时间，但不会更改为刷新时的当前时间。我必须停止脚本并重新运行它以便有时间刷新。如何让它显示当前时间？提前谢谢。

currenttime，但在api_seconds的并发调用中不会重新评估
currenttime，因为您的应用已加载。您可以改为移动api_seconds方法内的$(gridId).jqGrid({
colNames: ["Id", "Name", "Col 1", "Col 2", "Col 3"],
colModel: [
{ name: "Id", index: "Id", hidden: true, key: true, formatter: 'text' },
{ name: "Name", index: "Name", width: '165px', align: 'left', resizable: false, editable: false, classes: 'non-editable', formatter: 'text' },
{ name: "Col1", index: "Col1", width: '60px' },
{ name: "Col2", index: "Col2", width: '60px' },
{ name: "Col3", index: "Col3", width: '60px' }
],
hidegrid: false,
rowNum: 50,
rowList: [10, 20, 50, 100],
scroll: true,
loadonce: true,
sortorder: "asc",
height: 370,
datatype: 'json',
viewrecords: true,
mtype: 'GET',
ignoreCase: true,
jsonReader: {
root: "rows",
page: "page",
total: "total",
records: "records",
repeatitems: false,
userdata: "userdata"
},
url: gridUrl,
editurl: '#',
cellEdit: true,
cellsubmit: 'clientArray',
footerrow: true,
multiselect: false,
//autowidth: true,
cmTemplate: {
//Default col model properties, if not using default, override in the colmodel
resizable: false,
edittype: "text", //for checkbox, override in the colmodel
align: "right",
editable: true,
formatter: 'number', //for text, override in the colmodel
formatoptions: { decimalSeparator: ".", thousandsSeparator: "", decimalPlaces: 1, defaultValue: '', align: "right" },
editrules: { number: true} //Setting numeric validation for all columns as all the editable columns are numbers
},
beforeEditCell: function (rowid, cellname, value, iRow, iCol) {
var grid = $(this);
if (prevCellName != cellname && cellname == "Col2") {
var autoCalculated = 123;
var response = confirm("The Col 2 auto-calculated value is " + autoCalculated + ". Would you like to use this value?");
if (response == true) {
setTimeout(function () {
grid.jqGrid('setCell', rowid, "Col2", autoCalculated);
}, 10);
setTimeout(function () {
grid.jqGrid('editCell', iRow, iCol + 1, true);
}, 20);
}
}
prevCellName = cellname;
}
});
计算，并且每次都应该执行。

您在flask应用程序运行时设置currenttime，并且在应用程序重新启动之前不会更新。我会尝试将from flask import Flask
import time
@app.route('/api/<seconds>')
def api_seconds(seconds):
currenttime = int(round(time.time() * 1000))
milliseconds = int(seconds) * 1000
finaltime = int(currenttime + milliseconds)
return 'Seconds: ' + seconds + '<br />' + 'Milliseconds: ' + str(milliseconds) + \
'<br />' + 'Time: ' + str(currenttime) + '<br />' + 'Final Time: ' + str(finaltime)
放入您的路线功能
CREATE TABLE Date
(
"year" smallint NOT NULL DEFAULT extract(year from current_date)
);
