#2 楼

openweathermap.org和www.mocky.io都很可能支持http或端口80。以下是一些线索。

openweathermap.org





www.mocky.io





看起来像requestb.in仅支持HTTPS或端口443。

requestb.in





这可能解释了问题。以下是一些可能有用的参考。

在CC3100数据表中，没有对使用HTTPS的CC3100的引用。所有参考仅针对HTTP。这可能更好地解释了这个问题。在数据表的例外项下面附加一个数据。



每个数据表都类似CC3120支持HTTPS。下面的附件是数据表中的内容。对HTTPS的引用很少。



最可能的发展途径是用CC3120代替CC3100。

经过无数次编辑引入错误并加以纠正之后，现在可能正在成为一个实际的答案。但是您实际上仍然需要重写它：如果您的论点是一个站点支持http，而另一个站点仅支持https，则只需在前面说一下即可。

而且您对CC3100和替换建议的分析仍然完全错误。它明确表示它支持TLS / SSL，而当您试图通过与服务器无关的问题来错误地查看它的Web服务器功能时，则表示它不支持。问题实际上是根本没有使用HTTP库，而是在TCP套接字上手动进行操作。要联系HTTPS服务器，它需要在SSL连接上执行类似的操作。
