1测试用代码
项目中遇到的, 公司的开发不是前后端分离的模式, html页面是后端返回的, 所以页面需要根据客户端是PC还是手机调整布局;
试了一下在后端获取客户端类型, 方法是用请求报文里的 headers中的 user-agent 信息;
起初也不知道, 于是做了以下试验代码
@GetMapping(value = "/test")
public ModelAndView CheckLoginForModuleUse(HttpServletRequest req){
System.out.println("=======================访问端信息=======================");
Enumeration<String> headerNames = req.getHeaderNames();
while (headerNames.hasMoreElements()) {
String key = headerNames.nextElement();
System.out.print(key);
System.out.print("=");
System.out.println(req.getHeader(key));
}
System.out.println("=======================END=======================");
}
2 收集到的日志
部署并尝试用多种客户端访问后, 有以下日志产生, 本次使用的客户端有:
1 谷歌浏览器 windows
2 Edge浏览器 windows
3 iPhone手机App, (App是客户的app, 在app内部访问接口)
4 Android手机App
5 PC端App
比较遗憾没有 macbook 试试;文章来源：https://www.toymoban.com/news/detail-510712.html
eg.1 明显这个客户端是 iphone14

3 结论
经分析, 移动端的 user-agent 信息中都含有 Mobile 字样, 其中安卓机还带有 Android 字样, 苹果机带有 iPhone 字样;
最初分析的时候并没有注意到这个独有的 Mobile 字样, 所以我的代码是这样实现的文章来源地址https://www.toymoban.com/news/detail-510712.html
@GetMapping(value = "/test")
public ModelAndView CheckLoginForModuleUse(HttpServletRequest req){
String url = "xxxx";
String userAgent = req.getHeader("user-agent");
if (userAgent != null) {
userAgent = userAgent.toLowerCase();
if (userAgent.contains("android") || userAgent.contains("iphone")) {
// url中带上参数cusotmer=2标识类型, 页面html中已经做了处理, 自动根据customer的值调整布局
url += "&cusotmer=2";
}
}
}
