CASPERJS加密

Question

我的casperjs脚本有问题。我正在尝试在SQL中插入数据，但我有两条错误消息：

  

错误：找不到模块加密

我尝试了npm install crypto，但这并没有改变任何事情。 我试图检索nodesjs的json以在casper中传递它，它不起作用。

第二条错误消息是：

  

TypeError：Object不是构造函数（评估'new Connection   （{config：new ConnectionConfig（config）}）“）”。

我的剧本：

var fs = require('fs');

var casper = require('casper').create({
    verbose: true,
    logLevel: 'error',
    pageSettings: {

        loadImages: true,
        loadPlugins: true,
        clientScripts: ["../libs/jquery.min.js"]
    },
    onDie: function () {
        console.log('Page is died');
    },
    onPageInitialized: function () {
        console.log("Page Initialized");
    }
});


casper.on('remote.message', function (msg) {
    this.echo('remote message caught: ' + msg);
});

casper.on("page.error", function (msg, trace) {
    this.echo("Page Error: " + msg, "ERROR");
});

var url_connexion = 'https://accounts.zoho.eu/signin?servicename=ZohoCRM&signupurl=https://www.zoho.eu/crm/lp/signup.html';

CasperJS和PhantomJS与node.js不兼容（尽管某些 npm包可能如果他们不依赖于节点的内部模块并且不使用ES6）。

因此，您无法从CasperJS将数据直接保存到MySQL中。幸运的是有其他选择：

• 您可以使用您知道的语言构建一种中间人脚本，该脚本可以从CasperJS接收数据并将其放入MySQL中。您可以通过HTTP或CLI向其发送数据。例如，它可以是localhost上等待POST请求的简单PHP脚本。

• 您可以使用PhantomJS fs模块以SQL格式保存数据，然后生成MySQL进程以通过child process模块
