volley 获取cookie总结

1.获取服务器返回的cookie值，重写request中的parseNetworkResponse方法就可以了StringRequest request= new StringRequest(Method.POST, url,this, this) {@Overrideprotected Response<String> parseNetworkResponse(NetworkResponse response) {// TODO Auto-generated method stubtry {Map<String, String> responseHeaders = response.headers;String rawCookies = responseHeaders.get("Set-Cookie");String dataString = new String(response.data, "UTF-8");return Response.success(dataString,HttpHeaderParser.parseCacheHeaders(response));} catch (UnsupportedEncodingException e) {return Response.error(new ParseError(e));}}};

2.有时服务器会返回多个 Set-Cookie 值，而Volley默认只取第一个，如果有需求，就要自己修改Volley的代码啦，HurlStack（sdk_int>9会走这里)里面的performRequest，默认解析header方式如下，

多个值的话只需要拿到header.getValue().get(1)等等，具体需求可以自行修改。

Header h = new BasicHeader(header.getKey(), header.getValue().get(0));response.addHeader(h);3.给服务器上传Cookie值，，如下（因为该类实现了response和error接口，所以参数直接写的this）

StringRequest request= new StringRequest(Method.POST, url,this, this) {public Map<String, String> getHeaders() throws AuthFailureError {HashMap localHashMap = new HashMap();localHashMap.put("Cookie", "你的cookie值");return localHashMap;}//设置post参数protected Map<String, String> getParams() {if(params==null){return new HashMap<String, String>();}return params;}//设置编码格式@Overrideprotected Response<String> parseNetworkResponse(NetworkResponse response) {// TODO Auto-generated method stubtry {String dataString = new String(response.data, "UTF-8");return Response.success(dataString,HttpHeaderParser.parseCacheHeaders(response));} catch (UnsupportedEncodingException e) {return Response.error(new ParseError(e));}}};

只有一条路不能选择——那就是放弃的路;
