我有这段phantomjs代码，这应该将内容从 url 呈现/保存到 pdf 文件中；
在代码的末尾，我有这个数组：
arrayOfUrls = ["http://192.168.0.49/a/view/id/6", "http://192.168.0.49/a/view/id/5", "http://192.168.0.49/a/view/id/4"];
错误是：
Unable to render 'http://192.168.0.49/a/view/id/6'
Unable to render 'http://192.168.0.49/a/view/id/5'
Unable to render 'http://192.168.0.49/a/view/id/4'
// Render Multiple URLs to file
var RenderUrlsToFile, arrayOfUrls, system;
system = require("system");
/*
Render given urls
@param array of URLs to render
@param callbackPerUrl Function called after finishing each URL, including the last URL
@param callbackFinal Function called after finishing everything
*/
RenderUrlsToFile = function(urls, callbackPerUrl, callbackFinal) {
var getFilename, next, page, retrieve, urlIndex, webpage;
urlIndex = 0;
webpage = require("webpage");
page = null;
getFilename = function() {
return "rendermulti-" + urlIndex + ".pdf";
};
next = function(status, url, file) {
page.close();
callbackPerUrl(status, url, file);
return retrieve();
};
retrieve = function() {
var url;
if (urls.length > 0) {
url = urls.shift();
urlIndex++;
page = webpage.create();
page.viewportSize = {
width: 800,
height: 600
};
page.settings.userAgent = "Phantom.js bot";
return page.open("http://" + url, function(status) {
var file;
file = getFilename();
if (status === "success") {
return window.setTimeout((function() {
page.render(file);
return next(status, url, file);
}), 200);
} else {
return next(status, url, file);
}
});
} else {
return callbackFinal();
}
};
return retrieve();
};
arrayOfUrls = null;
if (system.args.length > 1) {
arrayOfUrls = Array.prototype.slice.call(system.args, 1);
} else {
console.log("Usage: phantomjs render_multi_url.js [domain.name1, domain.name2, ...]");
arrayOfUrls = ["http://192.168.0.49/a/view/id/6", "http://192.168.0.49/a/view/id/5", "http://192.168.0.49/a/view/id/4"];
}
RenderUrlsToFile(arrayOfUrls, (function(status, url, file) {
if (status !== "success") {
return console.log("Unable to render '" + url + "'");
} else {
return console.log("Rendered '" + url + "' at '" + file + "'");
}
}), function() {
return phantom.exit();
});
