问题描述
我正在使用 PhantomJS 在JavaScript DOM操作发生后获取生成的网页源。这个网页只有一个< body> ，没有别的。
I'm using PhantomJS to get the generated source of a web page after JavaScript DOM manipulations have taken place. This web page has JUST a <body> and nothing else.
重要 ：此网页使用浏览器的 localStorage 生成页面。
我想在打开页面之前更改PhantomJS中的LocalStorage。
I want to change LocalStorage in PhantomJS before opening the page.
App.js ：
var page = require('webpage').create();
page.open("https://sample.com")
setTimeout(function(){
// Where you want to save it
page.render("screenshoot.png")
// You can access its content using jQuery
var fbcomments = page.evaluate(function(){
return $("body").contents().find(".content")
})
phantom.exit();
}, 1000)
推荐答案
特定域的localStorage仅在您在该域上打开页面时可用。您可以
localStorage for a particular domain is only available when you open a page on that domain. You can
- 在您感兴趣的域名上打开一些网址，
- 更改
localStorage根据您的需要， - 在同一个域上打开您的目标网址。
- open some URL on the domain you're interested in,
- change
localStorageaccording to your needs, - open your target URL on the same domain.
这可能如下所示：
page.open("https://sample.com/asdfasdf", function(){
page.evaluate(function(){
localStorage.setItem("something", "whatever");
});
page.open("https://sample.com", function(){
setTimeout(function(){
// Where you want to save it
page.render("screenshoot.png")
// You can access its content using jQuery
var fbcomments = page.evaluate(function(){
return $("body").contents().find(".content")
})
phantom.exit();
},1000)
});
});
也可以不在步骤1中打开整页。您也可以使用虚拟页面网址。
It's also possible not to open a full page in step 1. You can also use dummy page with some URL.
page.setContent("", "https://sample.com"); // doesn't actually open any page
page.evaluate(function(){
localStorage.setItem("something", "whatever");
});
page.open("https://sample.com", function(){
setTimeout(function(){
// Where you want to save it
page.render("screenshoot.png")
// You can access its content using jQuery
var fbcomments = page.evaluate(function(){
return $("body").contents().find(".content")
})
phantom.exit();
}, 1000)
});
