android - 我的 wap 有很多错误让我很困惑

Question

最近我创建了 wap。我发现一个问题，如果我设置一个代理它可以连接。如果不设置代理则无法连接。但在此之前必须设置代理进行连接。

错误是:

HttpURLConnection 的getOutputStream() 方法有错误。

只有在设置代理时异常(exception)。谁遇到同样的问题？

Answer 1

看起来您正在向本地主机 (127.0.0.1) 发出请求

这在手机或模拟器上运行时不起作用，因为手机/emu 没有在端口 80 上服务的网络浏览器。

从可公开访问的地址提供您的网页，并将您的 http://localhost 或 http://127.0.0.1 替换为可公开访问的地址。

如果您需要从手机加载 html 文件，请不要使用 HTTP 类，请使用文件类。
