好的,所以我试图为多个网站运行多个屏幕截图!我有一个多个网站的屏幕截图,我也可以为一个网站获得多个Viewport屏幕截图,但我有34个网站,我想这样做!所以有人知道用casperjs做这个的方法吗?这是我认为可以工作的代码,但只有第一个网址,然后才结束!
var casper = require("casper").create();
var screenshotUrls = ["http://www.google.com", "http://www.yahoo.com", "http://www.espn.com"];
var screenshotPaths = ["google.com", "yahoo.com", "espn.com"];
screenshotNow = new Date(),
screenshotDateTime = screenshotNow.getFullYear() + pad(screenshotNow.getMonth() + 1) + pad(screenshotNow.getDate()),
viewports = [
{
'name': 'smartphone-portrait',
'viewport': {width: 320, height: 480}
},
{
'name': 'smartphone-landscape',
'viewport': {width: 480, height: 320}
},
{
'name': 'tablet-portrait',
'viewport': {width: 768, height: 1024}
},
{
'name': 'tablet-landscape',
'viewport': {width: 1024, height: 768}
},
{
'name': 'desktop-standard',
'viewport': {width: 1280, height: 1024}
}
];
i = 0;
//casper.start();
casper.start(screenshotUrls[i], function(self, screenshotUrl) {
this.echo('Current location is ' + this.getCurrentUrl(), 'info');
});
casper.each(viewports, function(casper, viewport) {
this.then(function() {
this.viewport(viewport.viewport.width, viewport.viewport.height);
});
this.thenOpen(screenshotUrls[i], function() {
this.wait(5000);
});
this.then(function(){
this.echo('Screenshot for ' + viewport.name + ' (' + viewport.viewport.width + 'x' + viewport.viewport.height + ')', 'info');
this.capture('screenshots/' + screenshotPaths[i] + '/' + screenshotDateTime + '/' + viewport.name + '-' + viewport.viewport.width + 'x' + viewport.viewport.height + '.png', {
top: 0,
left: 0,
width: viewport.viewport.width,
height: viewport.viewport.height
});
});
});
casper.run();
function pad(number) {
var r = String(number);
if ( r.length === 1 ) {
r = '0' + r;
}
return r;
}

以下是工作版本:
var casper = require("casper").create();
var screenshotUrls = ["http://www.google.com", "http://www.yahoo.com", "http://www.espn.com"];
var screenshotPaths = ["google.com", "yahoo.com", "espn.com"];
screenshotNow = new Date(),
screenshotDateTime = screenshotNow.getFullYear() + pad(screenshotNow.getMonth() + 1) + pad(screenshotNow.getDate()),
viewports = [
{
'name': 'smartphone-portrait',
'viewport': {width: 320, height: 480}
},
{
'name': 'smartphone-landscape',
'viewport': {width: 480, height: 320}
},
{
'name': 'tablet-portrait',
'viewport': {width: 768, height: 1024}
},
{
'name': 'tablet-landscape',
'viewport': {width: 1024, height: 768}
},
{
'name': 'desktop-standard',
'viewport': {width: 1280, height: 1024}
}
];
i = -1;
casper.start().eachThen(screenshotUrls, function(response) {
this.each(viewports, function(casper, viewport) {
this.then(function() {
this.viewport(viewport.viewport.width, viewport.viewport.height);
});
this.thenOpen(response.data, function() {
this.wait(5000);
});
this.then(function(){
this.echo('Screenshot for '+ screenshotPaths[i] + viewport.name + ' (' + viewport.viewport.width + 'x' + viewport.viewport.height + ')', 'info');
this.capture('screenshots/' + screenshotPaths[i] + '/' + screenshotDateTime + '/' + viewport.name + '-' + viewport.viewport.width + 'x' + viewport.viewport.height + '.png', {
top: 0,
left: 0,
width: viewport.viewport.width,
height: viewport.viewport.height
});
});
});
++i;
});
casper.run();
function pad(number) {
var r = String(number);
if ( r.length === 1 ) {
r = '0' + r;
}
return r;
}
