推荐答案

从我所看到的代码中没有任何问题。您的问题是因为您正在尝试访问不可用的网址，因为它尚未公开到互联网。

From what I can see there is nothing wrong with the code. Your issue is because you are trying to access a URL which is not available, since it is not yet exposed to the internet.

仅仅是为了测试是否存在网址没有错，我建议将 192.168.7.175/app/app.html 更改为更可信的网站，例如 http：// www。 google.com 暂时。

Just for the sake of testing that there is nothing wrong in the url, I recommend changing 192.168.7.175/app/app.html to a more plausable website such as http://www.google.com for the time being.

您的下一步是找到一种方法将您的网站暴露在网络上，这样就可以了可从您的设备访问。如果安装了IIS，则可以将网站内容复制到 C：\inetpub\www 文件夹。这将向知道网址的任何人公开（在网络上提供）您的网站。您也可以使用本教程来帮助您。

Your next step is to find a way to expose your website to the web, so that it is accessible from your device. If you have IIS installed, you can copy your website content to the C:\inetpub\www folder. This would expose (make it available on the web) your site to anyone knowing the url.
