如果没有在端口80上运行,我无法从Unity访问我的Web服务。这是我在Unity中使用的C#代码
private void RunSimulation()
{
string url = @"http://192.168.1.116:9000/simulate";
WWW goServer = new WWW(url);
}
在192.168.1.116上,我有一个正在使用端口9000监听的程序。我可以通过Web浏览器轻松访问此URL,我将得到预期的结果。
当我在Unity中尝试这个时,如果我检查goServer变量的内容,我会看到消息
System.Security.Exception:没有可用于允许访问的有效跨域策略
有一个跨域政策文件。它位于/var/www/html/crossdomain.xml具有以下内容:
<allow-access-from domain="*" to-ports="*" secure="false"/>
<site-control permitted-cross-domain-policies="all"/>
此文件之前存在,并且有.php程序能够成功调用。我添加了to-ports“*”以试图让它工作,但没有运气。
我试过让我的服务器在端口80上侦听。当我这样做时,我能够从Unity连接。有什么想法吗?
(The input sanitizer is defeating me and I can't figure out how to post without the input form telling me that my links are not allowed, so I'm going to omit 192.168.1.116:9000)
我在serverurl.com:9000/crossdomain.xml上没有得到任何东西 因此,我将一些代码放入我的服务器以响应此请求,并返回带有标头Access-Control-Allow-Origin,Access-Control-Allow-Headers和Access-Control-Allow-Credentials的响应。
我设置了ENABLE_CROSSDOMAIN_LOGGING环境变量。我在日志文件中看到这个以及更多

所以我认为我现在正在返回正确的标题,但我认为我还需要返回正文中的内容。我想我只会返回与我在端口80上查询时得到的crossdomain.xml文件相同的内容。
我知道我的服务器上的crossdomain.xml端点正在被命中。如果我理解统一输出的日志文件是什么,问题可能只是主体是空的并且我有一个空流。
答案 0 :(得分:1)
不需要代理,Unity已记录内置的跨域内容:查看the debuging section of the unity3d manual on the security sandbox并使用ENABLE_CROSSDOMAIN_LOGGING
启用跨域调试。然后在日志中查找结果。
可以肯定的是,http://192.168.1.116:9000/crossdomain.xml
可以访问跨域文件吗?
答案 1 :(得分:0)
我要做的是实现我自己的crossdomain.xml端点版本。它目前看起来像这样。
func crossdomain(res http.ResponseWriter,req * http.Request){ log.Println(“在跨域的顶部”)
if origin := req.Header.Get("Origin"); origin != "" {
res.Header().Set("Access-Control-Allow-Origin", origin)
}
res.Header().Set("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE")
res.Header().Set("Access-Control-Allow-Headers", "Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token")
res.Header().Set("Access-Control-Allow-Credentials", "true")
body := "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" +
"<!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=\"*\" 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>"
io.WriteString(res,body)
}
func main(){
http.HandleFunc("/simulate", simulate)
http.HandleFunc("/crossdomain.xml", crossdomain)
listenErr := http.ListenAndServe(":9000", nil)
}
