Question

我正在尝试使用casperjs / phantomjs http://m.10bet.com/#leage_panel#10096加载以下网页。

因此我编写了以下简单的casper脚本：

var casper = require('casper').create({
    verbose: true,
    logLevel: "debug"
});

if( casper.cli.args.length != 1 )
    casper.echo('No URL as arguments given. Exiting.\n').exit();

var id = casper.cli.args[0]
casper.start( 'http://m.10bet.com/#leage_panel#' + id, function() {
    casper.waitForResource("http://m.10bet.com/pagemethods.aspx/UpdateEvents", function() {
        this.echo(casper.getPageContent())
    }, function(){}, function(){}, 10000 );
});

casper.run(function() {
    this.echo('Done.').exit();
});

所以，我正在等待加载的最后一个资源，在这种情况下是“http://m.10bet.com/pagemethods.aspx/UpdateEvents”。我用chrome开发人员工具检查过这个。随后我想在控制台上输出渲染的html。

但是，但是在我看来，我得到了一个非常奇怪的错误，而不是html：

从日志中可以看到错误“加载资源失败，状态=失败（HTTP 200）：http://m.10bet.com/#leage_panel#10096”给出了一个http 200 ok但是失败了。最终，网页未在控制台上加载或打印。所以我想知道这里出了什么问题？

用法：

casperjs stackoverflow.js --idEvent=10096

代码：

var casper = require('casper').create ({
  waitTimeout: 15000,
  stepTimeout: 15000,
  verbose: true,
  viewportSize: {
    width: 1024,
    height: 768
  },
  pageSettings: {
    "userAgent": 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.10 (KHTML, like Gecko) Chrome/23.0.1262.0 Safari/537.10',
    "loadImages": false,
    "loadPlugins": false,
    "webSecurityEnabled": false,
    "ignoreSslErrors": true
  },
  onWaitTimeout: function() {
    casper.echo('Wait TimeOut Occured');
  },
  onStepTimeout: function() {
    casper.echo('Step TimeOut Occured');
  }
});

//vars
var idEvent = casper.cli.get('idEvent');

// start
casper.start();

// check args
casper.then(function() {
  if (!idEvent) {
    //usage check
    this.echo('Invalid usage: Must supply Event Id');
    casper.exit();
  }
});

casper.thenOpen('http://m.10bet.com/#leage_panel#' + idEvent, function() {
  casper.waitForResource('http://m.10bet.com/pagemethods.aspx/UpdateEvents', function() {
  //casper.waitForSelector('#league_block', function() {
  }, function then() {    //selector found
    this.echo(casper.getPageContent());
    casper.exit();
  }, function timeout() { //selector not found
    this.echo("Timeout On Selector...Exiting").exit();
  });
});

// executes
casper.run();

您的参数是否适用于其他脚本？我很好奇，因为文档显示参数以这种方式引用。

casper.echo(casper.cli.has(0));

我想知道这可能是问题吗？
