[英]How to stream/pipe response object from Zombie.js
How can I download a file with Zombie.js with a web app that uses http-equiv meta tag to emulate the Refresh HTTP header? 如何使用Zombie.js下载带有使用http-equiv元标记模拟Refresh HTTP标头的Web应用程序的文件?
In essence how do you download/stream/pipe a downloadable resource that is loaded after sometime have passed and not via a direct download link. 本质上,如何下载/流/管道在经过一段时间后加载的可下载资源,而不是通过直接下载链接。
I was thinking I could do it with the Zombie.js Pipeline... but the docs on that are pretty senseless to a zombiejs newbie 我以为我可以用Zombie.js Pipeline做到这一点......但对于zombiejs新手而言,这些文档对我来说是毫无意义的
Not sure if this would help you, but this helped me catch response bodies. 不确定这是否会对你有所帮助,但这有助于我找到回复机构。 (Copied from a GitHub issue .)

var Promise = require('bluebird');
const Browser = require('zombie');
const browser = new Browser();
browser.visit(myUrl, function() {
browser.click('body')
.then(function(){
return Promise.map(browser.resources, function(resource){
return (resource.response._bodyUsed)
? resource.response.body
: resource.response.text();
}).then(function(bodies){
console.log(bodies);
});
});
});

var fs = require('fs');
var URL = require('url');
var Request = require('request'); // Named 'Request' to prevent conflict with zombie's 'request' object
var Browser = require('zombie'), browser = new Browser();
browser.on('request', function (request) {
// let's pullover for a download incase we find our request signboard :)
if (request.url.indexOf('https://matchingString') == 0) {
console.log('Beginning download in a flash...');
var
parsedURL = URL.parse(request.url),
cookies = browser.cookies,
cookieHeader = cookies.serialize(parsedURL.hostname, parsedURL.pathname);
if (cookieHeader) request.headers.append('Cookie', cookieHeader);
var writeStream = fs.createWriteStream(pathToFileYetToBeWritten);
writeStream
.on('error', function(err) {
console.error(err);
})
.on('finish', function() {
console.log('finished writing file');
});
Request({
method: request.method,
uri: request.url,
headers: request.headers.toObject(),
proxy: browser.proxy,
body: request.body,
jar: false,
followRedirect: false,
strictSSL: browser.strictSSL,
localAddress: browser.localAddress || 0
})
.on('error', function(err) {
console.error(err);
})
.pipe(writeStream);
}
});
browser.visit(url, function () {
browser.wait(6000); // Wait only if you need to
});
