Windows phone8.1教務線上用戶端

標籤：

本人是個大二學生，由於學校的教務線上一直沒出windows phone的教務線上，而且本身也對wp開發感興趣，所以就嘗試著開發一下

由於沒有系統的學習，只能在摸索中前進，這背後的原理很簡單，可不容易實現，網上也沒合適的教程，下面是本人嘗試著寫登入頁面的代碼，

不過還是有些文法上的問題，希望能幫看看

            this.NavigationCacheMode = NavigationCacheMode.Required;
        }
        private async void button_Click(object sender, RoutedEventArgs e)
        {
            //這句postdata的拼字可能有錯誤，考慮用索引值對的方式
            string loginstr = "j_username=" + textBox1.Text + "&j_password=" + passwordBox.ToString();

            CookieContainer cookie = await GetCookie(loginstr,"http://60.18.131.131:11080/newacademic/common/security/login.jsp");
            string content = await GetContent(cookie, "http://60.18.131.131:11080/newacademic/frameset.jsp");
            Frame.Navigate(typeof(BlankPage1), content);
            textBox2.Text = content;
        }

        public async Task<CookieContainer> GetCookie (string postString,string postUrl)
        {
            CookieContainer cookie = new CookieContainer();
            HttpWebRequest httpRequest = (HttpWebRequest)WebRequest.Create(postUrl);
            //下面這個要求標頭的資訊不知如何改進啊,反正有什麼我就把它添上了
            httpRequest.CookieContainer = cookie;//設定cookie
            httpRequest.Method = "POST";//POST提交
            httpRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
            httpRequest.ContentType = "application/x-www-form-urlencoded";
            byte[] bytes = System.Text.Encoding.UTF8.GetBytes(postString);
            Stream stream = await httpRequest.GetRequestStreamAsync();
            stream.Write(bytes, 0, bytes.Length);//以上是post資料的寫入，不知還有什麼疏漏之處          
            HttpWebResponse httpResponse =(HttpWebResponse)await httpRequest.GetResponseAsync();
            return cookie;
        }

        public async Task<string> GetContent(CookieContainer cookie,string url)
        {
            string content;
            HttpWebRequest httpRequest = (HttpWebRequest)HttpWebRequest.Create(url);
            httpRequest.CookieContainer = cookie;
            httpRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
            httpRequest.ContentType = "application/x-www-form-urlencoded";
            httpRequest.Method = "GET";
            HttpWebResponse httpResponse = (HttpWebResponse)await httpRequest.GetResponseAsync();
            using(Stream responseStream = httpResponse.GetResponseStream())
            {
                using (StreamReader sr = new StreamReader(responseStream,System.Text.Encoding.UTF8))
                {
                    content = sr.ReadToEnd();
                }
            }
            return content;
        }
    }
}

邏輯上大致是先類比登陸，然後拿到cookie，再帶著這個cookie訪問登陸上的網頁，（然後通過解析html擷取自己想要的內容，這部分還沒做）

不過並不能取到所返回的content，希望有經驗的園友指導一下
