Run Code Online (Sandbox Code Playgroud) 我正在开发一个下载管理器并尝试使用获取cookie所需的内容HttpWebRequest.我想将我的应用程序集成到Chrome,因此我可以从浏览器中获取必要的Cookie标头和值.
但首先我需要知道是否需要cookie才能获得要下载的内容以及它们是哪些cookie.我找不到有关此主题的任何有用资源.
这就是我的想象:
HttpWebRequest req = (WebRequest.Create(url)) as HttpWebRequest;
//At first, get if cookies are necessary?
//If it is, get the required cookie headers
//Then add the cookies to the request
CookieContainer cc = new CookieContainer();
Cookie c1 = new Cookie("header1", "value1");
Cookie c2 = new Cookie("header2", "value2");
CookieCollection ccollection = new CookieCollection();
ccollection.Add(c1);
ccollection.Add(c2);
cc.Add(uri, ccollection);
req.CookieContainer = cc;
//Get response and other stuff......

我正在使用临时文件来存储mp3数据,我想FileStream根据用户选择的位置重新定位.但它有一个问题.
这可以使用WebRequest.AddRange()但是在这种情况下,我们必须打开一个新的FileStream来分别存储字节,并且AddRange()每次用户想要前进或后退时调用方法意味着将从该位置重新下载文件.但是,如果这种情况经常发生,我们必须下载与前向或后向数量一样多的文件.
因此,如果有一个简单且配额友好的解决方案,请告诉我.我无法弄清楚该怎么做.请帮忙!
