最近在使用接口时候，我使用get请求时，需要携带登录态，所以在get请求的时候我需要在head里面把cookie给加上，添加方式get和post完全不一样
Post方式添加cookie
httpPost = new HttpPost(url); ????????????????????????//添加代理配置 // 设置代理 ???????????RequestConfig config = RequestConfig.custom().setProxy(proxy).build(); ???????????//设置参数 ?????????????List<NameValuePair> list = new ArrayList<NameValuePair>(); ?????????????Iterator iterator = map.entrySet().iterator(); ?????????????while(iterator.hasNext()){ ?????????????????Entry<String,String> elem = (Entry<String, String>) iterator.next(); ?????????????????list.add(new BasicNameValuePair(elem.getKey(),elem.getValue())); ????????????????System.out.println("请求的参数为:"+elem.getKey()+":"+elem.getValue()); ???????????} ?????????????if(list.size() > 0){ ?????????????????UrlEncodedFormEntity entity = new UrlEncodedFormEntity(list,"utf-8"); ?????????????????httpPost.setEntity(entity); ?????????????} ???????????????????????????????//设置头部信息 ???????????httpPost.setHeader("Referer","http://oms.hqygou.com/order/temp/new"); ???????????httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8"); ????????????httpPost.setHeader("X-Requested-With","XMLHttpRequest"); ???????????httpPost.setHeader("Cookies",cookies);get请求设置头部信息
???????????????HttpGet httpGet = new HttpGet(url);httpGet.setHeader("Connection","keep-alive");httpGet.addHeader(new BasicHeader("Cookie", cookies));注意了使用：setHeader如果有这个cookie就会在后面直接添加这个cookie
addHeader没有这个cookie就新增这个cookie
httpclient使用head添加cookie
