Question

目前我的问题简化了：

下面的代码在统一编辑器中工作，我已经多次检查过php，现在发送的url工作，并且它返回正确的值，但是将内容上传到要在facebook app中使用的空间中断由于某种原因，img提供了显示停止的地方。

其他一些细节：

环顾所有迹象表明它是v3.0的错误（版本I＆＃39;我正在使用v4.3.3f1），但是虽然我的代码在编辑器中工作没有问题，但它赢得了＃39 ;当我将其构建上传到我提供的html空间时，t继续通过yield return www请求。

在下面的块之前登录工作的当前方式是初始化FB游戏对象，登录到Facebook，检查没有错误，然后传回FB用户ID，然后传递给下面的代码 - 其按预期工作

快速编辑 - 数据库连接器包含主URL，下面的代码添加到php get的必要字符串上。

我不知道从哪里开始尝试修复它，除了如图所示更改正在显示的文本，这有助于将其分解为我的问题。

在浏览器中运行时有不同的规则。如上所述，here应用程序处于沙盒模式，因此您需要添加crossdomain策略（我知道该链接适用于Flash Player，但适用相同的原则）。

最后，您需要保存在Web服务器根目录中 crossdomain.xml 文件中的此类内容。

<?xml version="1.0"?>
<cross-domain-policy>
 <allow-access-from domain="*" secure="false"/>
</cross-domain-policy>

Unity www yield return请求在编辑器中有效，但在fb app中无效
