当我尝试将更改提交到本地repo时,我收到以下消息:

我是python新手,我无法理解如何正确格式化日期。

我正在这样准备:
dates.append(time.strptime(row[5], "%a, %d %b %Y %H:%M:%S %Z"))

有人使用 koa.js 和流吗?
考虑这个例子
const fs = require('fs');
const Koa = require('koa');
const app = new Koa();
app.use(async (ctx) => {
ctx.body = fs.createReadStream('really-large-file');
});
app.listen(4000);

Javascript源代码如下所示:
var map, layer;
map = new OpenLayers.Map('map');
layer = new OpenLayers.Layer.OSM("Simple OSM Map");
map.addLayer(layer);
var projection = new OpenLayers.Projection("EPSG:4326");
var center = new OpenLayers.LonLat(-71.147, 42.472).transform(projection, map.getProjectionObject());
map.setCenter(center, 12);

我已经重写了这样的代码:
(ns hello.map)
(def mapp (.Map js/OpenLayers "map"))
(def layer (.Layer.OSM js/OpenLayers "Simple OSM Map"))
(.addLayer mapp layer)
(def projection (.Projection js/OpenLayers "EPSG:4326"))
(def center (.Transform (.LonLat js/OpenLayers -71.147 42.472) projection (.getProjectionObject mapp)))
