单位crossdomain.xml

Question

我收到有关crossdomain.xml文件的错误消息，我不知道如何解决它。我没有困难从网页浏览器访问URL。

来自web浏览器

http://192.168.1.116:80/locJSON.txt

把JSON的大片段还给我

来自web浏览器

http://192.168.1.116/crossdomain.xml

将跨域信息还给我

<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" to-ports="*" secure="false"/>
<allow-access-from domain="*" to-ports="*"/>
<allow-access-from domain="*"/>
<allow-http-request-headers-from domain="*"  to-ports="*"/>
<allow-http-request-headers-from domain="*"/>
<site-control permitted-cross-domain-policies="all"/>

但是从内部统一，如果我尝试下面的代码，我会遇到问题。

private void QueryAIServer()
{
    string url = "http://192.168.1.116/locJSON.txt";
    WWW AIServer = new WWW(url);

    while(!AIServer.isDone) { };

    Debug.Log("Connected to AI Server!");
}

当我通过while行时，如果我检查调试器中的AIServer变量，就可以看到消息"System.Security.SecurityException: No有效的允许访问的跨域策略“，该消息以红色绘制，用于AIServer.bytes、AIServer.data和AIServer.text。

另外，我确实在控制台中得到了以下消息输出。任何洞察力都将不胜感激。

Answer 1

试试这个标准，允许所有的crossdomain.xml：

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>

   <allow-access-from domain="*" secure="false" />
</cross-domain-policy>
