折腾：
【未解决】Java给OkHttp加cookie出错：Cannot resolve symbol setCookiePolicy和Unknown class CookiePolicy.ACCEPT_ALL
期间，需要去把一个user-agent字符串：
public static String UserAgent_Mac_Chrome = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36";
优化改造为更加完整的写法，变成字符串的枚举
java string enum
【总结】
最后用代码：
// public static String UserAgent_Mac_Chrome = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36";
public enum UserAgent {
MAC_CHROME("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36"),
MAC_SAFARI("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/12.0 Safari/605.1.15")
;
private String text;
/**
* @param text
*/
UserAgent(final String text) {
this.text = text;
}
public String getText() {
return this.text;
}
/* (non-Javadoc)
* @see java.lang.Enum#toString()
*/
@Override
public String toString() {
return this.getText();
}
public static UserAgent fromString(String text) {
for (UserAgent eachUaValue : UserAgent.values()) {
if (eachUaValue.text.equalsIgnoreCase(text)) {
return eachUaValue;
}
}
return null;
}
}
}调用：
.header("User-Agent", CrifanUtil.UserAgent.MAC_CHROME.getText())即可实现：此处的字符串的枚举
且还支持从字符串中生成枚举值
以及获取到枚举值的字符串。
