我正在使用Phantomjs。我需要将某些信息传递到我们定位的网页（http://localhost:4569/index.html）。这个想法是，一旦目标页面加载，就将JSON对象传递给page＆amp;设置一个全局可访问的变量。像window.data = {....}这样的东西。设置此变量后，目标页面将使用此变量。是否可以使用Phantomjs获得所需的结果？
var webPage = require('webpage');
var page = webPage.create();
var settings = {
operation: "POST",
encoding: "utf8",
headers: {
"Content-Type": "application/json"
},
data: JSON.stringify({
some: "data",
another: ["custom", "data"]
})
};
page.open('http://localhost:4569/index.html', settings, function(status) {
console.log('Status: ' + status);
//

您可以通过setInterval和injectJs()的组合来实现这一目标。我会每隔几秒检查目标页面中的数据。然后我会使用injectJs注入一段数据。然后我会消化注入的数据并让phantomjs脚本做出相应的反应。
<html>
<head>
<title>Phantest</title>
</head>
<body>
<main>
<h1>Phantom Test</h1>
<p>Test of phantom</p>
</main>
<script>
(function () {
console.log("Hello");
setInterval(function () {
if (window.myVar) {
console.log("window.myVar is here!");
console.log(window.myVar);
}
}, 1000);
}());
</script>
</body>
</html>
/*jslint node:true*/
"use strict";
var page = require("webpage").create();
page.onConsoleMessage = function (msg) {
console.log(msg);
};
page.open("http://127.0.0.1:52987/index.html", function (status) {
if (status === "success") {
page.injectJs("inject.js");
}
});
/*jslint browser:true devel:true*/
console.log("I'm from Phantom");
window.myVar = "I'm myVar!";
