问题描述

该phantomjs脚本的输出不应该是240x320像素吗?我得到了一个大型默认尺寸的图像.夹克()似乎可以呈现正确的尺寸图像，但是我需要页面的响应内容来反映实际的浏览器窗口大小.

var page = require('webpage').create();

page.viewportSize = { width: 240, height: 320 };  

page.open('http://cnn.com', function (status) {

    if (status !== 'success') {
        console.log('Unable to load the address!');
    } else {
        window.setTimeout(function () {
            page.render('default.png');
            phantom.exit();
        }, 200);
    }

});

这有效！在问题的GitHub页面上找到了片段./p>

var width = 1024;
var height = 768;
var webpage = require('webpage');

page = webpage.create();
page.viewportSize = {width: width, height: height};
page.open('http://harness.io', function(status) {
    console.log(status);
    page.evaluate(function(w, h) {
      document.body.style.width = w + "px";
      document.body.style.height = h + "px";
    }, width, height);
    page.clipRect = {top: 0, left: 0, width: width, height: height};                                                                                                                           
    page.render('/tmp/test.png');
    phantom.exit();
});

这似乎在Mac二进制中起作用1.9.7:

page.set('viewportSize', {width: 320, height: 480});

问题描述

Shouldn't the output from this PhantomJS script be 240x320 pixels? I'm getting a large, default-sized image. clipRect() would seem to render the correct size image, but I need the responsive content of the page to reflect the actual browser window size.

var page = require('webpage').create();

page.viewportSize = { width: 240, height: 320 };  

page.open('http://cnn.com', function (status) {

    if (status !== 'success') {
        console.log('Unable to load the address!');
    } else {
        window.setTimeout(function () {
            page.render('default.png');
            phantom.exit();
        }, 200);
    }

});

This works!! Found the snippet on the github page of the issue.It forces the 'body' element to the page viewportSize:

var width = 1024;
var height = 768;
var webpage = require('webpage');

page = webpage.create();
page.viewportSize = {width: width, height: height};
page.open('http://harness.io', function(status) {
    console.log(status);
    page.evaluate(function(w, h) {
      document.body.style.width = w + "px";
      document.body.style.height = h + "px";
    }, width, height);
    page.clipRect = {top: 0, left: 0, width: width, height: height};                                                                                                                           
    page.render('/tmp/test.png');
    phantom.exit();
});

This seems to work in the Mac binary for 1.9.7:

page.set('viewportSize', {width: 320, height: 480});
