为什么我的Flex as3 crossdomain.xml不起作用？ [英] Why is my Flex as3 crossdomain.xml not working?

问题描述

我花了很多时间去弄清楚我的crossdomain.xml实现出了什么问题。这里有很多关于他们的问题，我已经尝试了每个问题的一切。

我使用Azure Blob存储来存储我的swf需要访问的图像。另外我正在使用BulkLoader swc来加载这些资产。下面是在应用程序尝试从url加载图像之前运行的代码。

  Security.allowDomain（mydomain.blob.core.windows.net）; 
 Security.allowInsecureDomain（mydomain.blob.core.windows.net）; 
 Security.loadPolicyFile（http://mydomain.blob.core.windows.net/crossdomain.xml）; 
  

下面是我尝试过的不同crossdomain.xml配置的示例。我可能已经尝试过20种不同的配置，而且没有任何效果。

<1>

 <？xml version =1.0？> 
<！DOCTYPE跨域策略系统http://www.adobe.com/xml/dtds/cross-domain-policy.dtd\"> 
<跨网域政策> 
 < allow-access-from domain =*/> 
< allow-http-request-headers-from domain =*headers =*/> 
< / cross-domain-policy> 
  

<2>

 <？xml version =1.0？> 
<！DOCTYPE跨域策略系统http://www.adobe.com/xml/dtds/cross-domain-policy.dtd\"> 
<跨网域政策> 
  < allow-http-request-headers-from domain =*headers =*secure =false/> 
< / cross-domain-policy> 
  

<3>

 <？xml version =1.0？> 
<！DOCTYPE跨域策略系统http://www.adobe.com/xml/dtds/cross-domain-policy.dtd\"> 
<跨网域政策> 
< allow-access-from domain =*/> 
< / cross-domain-policy> 
  

这是我在Flashlog文件中得到的错误。

  *** Security Sandbox Violation *** 
 SecurityDomain'http：// localhost：81 / controller / view'试图访问不兼容的
上下文'http://mydomain.blob.core.windows.net/crossdomain.xml'
  

任何帮助将不胜感激。这个问题让我疯狂。提前致谢。

解决方案

所以我想清楚我做错了什么。你需要发送一个LoaderContext的bulkLoader，就像你对普通的Loader类一样。这是我用过的代码。加载声音文件时也使用SoundLoaderContext。

  var currentSecurityDomain：SecurityDomain = null; 
 if（Security.sandboxType == Security.REMOTE）
 currentSecurityDomain = SecurityDomain.currentDomain; 
 
 var loaderContext = new LoaderContext（true，ApplicationDomain.currentDomain，currentSecurityDomain）; 
 
 var currentSecurityDomain：SecurityDomain = null; 
 if（Security.sandboxType == Security.REMOTE）
 currentSecurityDomain = SecurityDomain.currentDomain; 
 
 var soundLoaderContext = new SoundLoaderContext（1000，true）; 
 
 var currentSecurityDomain：SecurityDomain = null; 
 if（Security.sandboxType == Security.REMOTE）
 currentSecurityDomain = SecurityDomain.currentDomain; 
 
 var loaderContext = new LoaderContext（true，ApplicationDomain.currentDomain，currentSecurityDomain）; 
 var soundLoaderContext = new SoundLoaderContext（1000，true）; 
 
 var bulkLoader：BulkLoader = new BulkLoader（main）; 
 bulkLoader.add（URL，{context：loaderContext，id：animationID，maxTries：1，priority：priority}）; 
 bulkLoader.add（URL_TO_SOUND，{context：soundLoaderContext，id：animationID，maxTries：1，priority：priority}）; 
 bulkLoader.addEventListener（BulkLoader.COMPLETE，onAllItemsLoaded）; 
 bulkLoader.start（）; 
  

I have spent so much time trying to figure out what is going wrong with my crossdomain.xml implementation. There are tons of questions here about them and I have tried everything from every question.

I am using Azure Blob Storage to store images that my swf needs to access. Also I am using the BulkLoader swc to load in these assets. Below is code that runs before the application attempts to load images from the url.

Security.allowDomain("mydomain.blob.core.windows.net");
Security.allowInsecureDomain("mydomain.blob.core.windows.net");
Security.loadPolicyFile("http://mydomain.blob.core.windows.net/crossdomain.xml");

Here is a sample of different crossdomain.xml configurations I have tried. I've probably tried 20 different configurations and nothing seems to work.

1.

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
  <site-control permitted-cross-domain-policies="all" />
  <allow-access-from domain="*" />
  <allow-http-request-headers-from domain="*" headers="*" />
</cross-domain-policy>

2.

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
  <site-control permitted-cross-domain-policies="master-only" />
  <allow-access-from domain="*" secure="false" />
  <allow-http-request-headers-from domain="*" headers="*" secure="false" />
</cross-domain-policy>

3.

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
  <allow-access-from domain="*"/>
</cross-domain-policy>

This is the error I get in the flashlog file.

*** Security Sandbox Violation ***
SecurityDomain 'http://localhost:81/controller/view' tried to access incompatible
context 'http://mydomain.blob.core.windows.net/crossdomain.xml'

Any help would be appreciated. This problem is driving me crazy. Thanks in advance.

解决方案

So I figured out what I was doing wrong. You need to send bulkLoader a LoaderContext just like you do to the normal Loader class. Here is the code I've used. Also use a SoundLoaderContext when loading a sound file.

var currentSecurityDomain:SecurityDomain = null;
if (Security.sandboxType == Security.REMOTE)
    currentSecurityDomain = SecurityDomain.currentDomain;

var loaderContext = new LoaderContext(true, ApplicationDomain.currentDomain, currentSecurityDomain);

var currentSecurityDomain:SecurityDomain = null;
if (Security.sandboxType == Security.REMOTE)
    currentSecurityDomain = SecurityDomain.currentDomain;

var soundLoaderContext = new SoundLoaderContext(1000, true);

var currentSecurityDomain:SecurityDomain = null;
if (Security.sandboxType == Security.REMOTE)
    currentSecurityDomain = SecurityDomain.currentDomain;

var loaderContext = new LoaderContext(true, ApplicationDomain.currentDomain, currentSecurityDomain);
var soundLoaderContext = new SoundLoaderContext(1000, true);

var bulkLoader:BulkLoader = new BulkLoader("main");
bulkLoader.add(URL, { context: loaderContext, "id":animationID, maxTries:1, priority:priority});
bulkLoader.add(URL_TO_SOUND, { context: soundLoaderContext, "id":animationID, maxTries:1, priority:priority});
bulkLoader.addEventListener(BulkLoader.COMPLETE, onAllItemsLoaded);
bulkLoader.start();
