Unity crossdomain.xml

本文关键字：xml crossdomain Unity | 更新日期: 2023-09-27 18:19:28

我收到了关于crossdomain.xml文件的错误消息，我不知道如何解决它。我从web浏览器访问URL没有问题。

从web浏览器

http://192.168.1.116:80/locJSON.txt

很好地给了我一个JSON的大片段

从web浏览器

http://192.168.1.116/crossdomain.xml

给我跨域信息

<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"/>

但在Unity内部，如果我尝试以下代码，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!");
}

当我越过while行时，如果我在调试器中检查AIServer变量内部，我可以看到AIServer.bytes、AIServer.data和AIServer.text 的红色消息"System.Security.SecurityException:No valid cross-domain policy available to allow access"

此外，我确实在控制台中输出了以下消息。任何见解都将不胜感激。

Unity crossdomain.xml

让我多次关注的一件事是，没有将其保存为UTF-8编码。如果你在记事本中打开了它，并在做出更改后重新保存，一些编辑会这样做。记事本（至少是Windows 8.1中的版本）有一个选择框，用于检查保存时要使用的编码类型，默认为ANSI。

编辑：我想确保的一件事是——我相信你只是省略了它，但为了清楚起见，跨域中的标签需要用<cross-domain-policy></cross-domain-policy>包围，而与所有XML文件一样，第一个元素总共需要是<?xml version="1.0" ?>。。

<?xml version="1.0" ?>
<cross-domain-policy>
    <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"/>
</cross-domain-policy>

尝试这个标准允许所有跨域.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>
