我們現在做的項目,移動端和pc端網站通路的是同一套接口,那麼如何在接口中區分是手機通路還是pc短通路呢?
核心思想:根據請求頭(request header)來判斷,如何請求沒有header或僞造user agent則無法判斷.
先看一些user agent的執行個體:
mozilla/5.0 (windows nt 6.1; wow64; rv:35.0) gecko/20100101 firefox/35.0
mozilla/5.0 (iphone; cpu iphone os 8_1_2 like mac os x) applewebkit/600.1.4 (khtml, like gecko) (engine, like url) mobile/12b440 micromessenger/6.0.1 nettype/3g+
mozilla/5.0 (linux; u; android 4.2.2; zh-cn; 2013023 build/hm2013023) applewebkit/533.1 (khtml, like gecko) version/4.0 ucbrowser/9.9.5.489 u3/0.8.0 mobile safari/533.1
opera/9.80 (android 2.3.7; linux; opera mobi/46154) presto/2.11.355 version/12.10
mozilla/5.0 (linux; u; android 4.2.1; zh-cn; huawei g700-u00 build/huaweig700-u00) applewebkit/534.30 (khtml, like gecko) version/4.0 mobile safari/534.30 v1_and_sq_5.3.1_196_yyb_d qq/5.3.1.2335 nettype/wifi
mozilla/5.0 (linux; u; android 4.0.4; zh-cn; hs-eg906 build/imm76d) applewebkit/534.30 (khtml, like gecko) version/4.0 mobile safari/534.30 micromessenger/5.3.1.67_r745169.462
mozilla/5.0 (linux; u; android 4.4.2; zh-cn; gt-i9500 build/kot49h) applewebkit/537.36 (khtml, like gecko)version/4.0 mqqbrowser/5.0 qq-manager mobile safari/537.36
以下是我封裝的一套方法
clientosinfo 是用于儲存通路裝置資訊的,結構如下(省略getter,setter):
public class clientosinfo {
/***
* 比如 android_3.0
*/
private string ostypeversion;
* pad或phone
private string devicetype;
* os type
private string ostype;
* 隻是版本号,例如"4.1.1"
private string version;
private string useragent;
/***
* 是否是移動裝置
* @return
public boolean ismobile(){
return (!valuewidget.isnullorempty(this.devicetype));
}
}
核心方法:
* 當移動端(手機或pad)通路網頁時擷取移動端作業系統資訊
* @param request
* @return
*/
public static clientosinfo getmobileosinfo(httpservletrequest request){
string useragent=request.getheader("user-agent");
if(valuewidget.isnullorempty(useragent)){
useragent=request.getheader("user-agent");
clientosinfo info= headerutil.getmobilos(useragent);
info.setuseragent(useragent);
return info;
核心工具類:用于解析user agent
package com.common.util;
import java.util.regex.matcher;
import java.util.regex.pattern;
import com.common.bean.clientosinfo;
import com.string.widget.util.valuewidget;
