Contant.cookie 这个是自己写的一个全局变量，写起来很简单
public class Contant{
public static volatile String cookie = null;
}

StringRequest request = new StringRequest(Request.Method.GET, url, listener,
errorListener) {
public Map<String, String> getHeaders() throws AuthFailureError {
if (Contant.localCookie != null && Contant.localCookie.length() > 0) {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("cookie", Contant.Cookie);
Log.d("调试", "headers--" + headers);
return headers;
}else {
return super.getHeaders();
}
}
};
