本文整理了Java中okhttp3.internal.Util.canonicalizeHost()方法的一些代码示例，展示了Util.canonicalizeHost()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Util.canonicalizeHost()方法的具体详情如下：
包路径：okhttp3.internal.Util
类名称：Util
方法名：canonicalizeHost

Util.canonicalizeHost介绍

[英]If host is an IP address, this returns the IP address in canonical form.

Otherwise this performs IDN ToASCII encoding and canonicalize the result to lowercase. For example this converts ☃.net to xn--n3h.net, and WwW.GoOgLe.cOm to www.google.com. null will be returned if the host cannot be ToASCII encoded or if the result contains unsupported ASCII characters.
[中]如果主机是一个IP地址，则返回标准形式的IP地址。
否则将执行IDN ToASCII编码，并将结果规范化为小写。例如，这个转换☃.净到xn--n3h。net和WwW.GoOgLe。cOm访问www.google。通用域名格式。如果主机无法进行ASCII编码，或者结果包含不支持的ASCII字符，则将返回null。
