java.net无法解析域名

问题描述 投票:0回答:1

所以,我在本地主机上进行项目,一切运行顺利。我能够对服务器进行请求调用,并从我的android得到响应。没问题。然后我从AWS得到了一个ec2,并且没有映射到任何域名。所以,当我使用curl或邮递员发出请求时,它可以很好地工作。一切正常。但是我尝试从我的Retrofit发出请求的URL却是

HTTP FAILED: java.net.UnknownHostException: Unable to resolve host "ec2-11-130-81-251.ap-south-1.compute.amazonaws.comapi": No address associated with hostname

我还确保我已经在手机和所有内容中都授予了互联网许可。因此,从Android手机发出网络请求时,必须具有域名吗?有什么办法可以绕过这些东西吗?

如果有帮助,这是我的改装单例课程。谢谢

        return retrofit;

通过在基本URL中添加斜杠来解决。就是说,如果您的基本URL是www.some_base_url.com,则在启动改造实例时,它应该是www.some_base_url.com/。所以。如果出现该错误,请确保最后添加一个斜杠。
