android 中设置http请求头headers的Cookie

Posted 2022-12-03 IyangcLove

为了验证的安全， 有些应用 会对headers设置cookie 才能进行以后的操作。网上查阅了很多资料，自己也走了些弯路 总算搞出来了  。直接上代码

class NetThr       


    public static String sessionid=null;
  
            //请求的url ，json数据， 服务的类型(获取cookie)   
			public void  netThr(String svrurl, String message,int svrType) 		
					String svraddr = "";
		            svraddr = svrurl.replace(" ", "%20");
					URL svr = new URL(svraddr);
						if (message == null)
				            message = "";				
				try 
					HttpURLConnection httpreq = (HttpURLConnection) svr.openConnection();
					httpreq.setConnectTimeout(60000);
					httpreq.setReadTimeout(60000);
					if (message.length() > 0)
						httpreq.setRequestMethod("POST");
					else
						httpreq.setRequestMethod("GET");
					httpreq.setDoInput(true);
					
					if (message.length() > 0) 
						httpreq.setDoOutput(true);
						 httpreq.setRequestProperty("Charset", "UTF-8");	
						httpreq.setRequestProperty("Content-length", "" + message.getBytes("UTF-8").length);
						httpreq.setRequestProperty("Content-Type", "application/json");
					
					if (sessionid!=null&&svrType!=HandleRespFun.API_TYPE_GETCOOKIE)
					
                        //设置Cookie 到 Headers 
						httpreq.setRequestProperty("Cookie",sessionid);
					
					httpreq.connect();
					if (message.length() > 0) 
						OutputStream os = httpreq.getOutputStream();
						DataOutputStream dos = new DataOutputStream(os);
						dos.write(message.getBytes("UTF-8"));
						dos.close();
					
						
			//返回的headers 例子			
			//		Content-Type	application/json
            //        Set-Cookie	api_authenticated=1
            //        Set-Cookie	user_authenticated=1
            //        Set-Cookie	JSESSIONID=16i51l7jwmodpb1u1jfpdk0pg;Path=/laundry
            //        Expires	Thu, 01 Jan 1970 00:00:00 GMT
            //        Content-Length	175
            //        Server	Jetty(9.2.3.v20140905)
            //        Date	Tue, 27 Jan 2015 02:32:09 GMT							
						
			      //获取Cookie
			      if(svrType==HandleRespFun.API_TYPE_GETCOOKIE)
					Map<String, List<String>> kk = httpreq.getHeaderFields();
					List<String> cook = kk.get("Set-Cookie");
					if(cook!=null)
					for (String onecook : cook) 
						Log.v("Jashon", "Cookie is:" + onecook);
						if (onecook.contains("JSESSIONID"))
						
                            //sessionid=JSESSIONID=16i51l7jwmodpb1u1jfpdk0pg
							sessionid=onecook.split(";")[0];
						
					
			
			
			

 之前的时候 截取 sessionid部分截取错了  这里要注意一下哦。代码有点乱，不过主要方法逻辑 还是清晰的 希望能帮到一些盆友 自己以后也会用得着
