Environment.getEffectiveURLEscapingCharset介绍

[英]Returns the name of the charset that should be used for URL encoding. This will be null if the information is not available. The function caches the return value, so it's quick to call it repeatedly.
[中]返回应用于URL编码的字符集的名称。如果信息不可用，则为null。该函数缓存返回值，因此可以快速地重复调用它。
