上一篇文章分享了透過POST 方式傳資料回Server,這一篇來談談有關於透過GET的方式傳遞 首先,如我預期的一樣,透過網址傳遞,會產生編碼問題,這邊我就順代解掉,希望有碰到的人 可以不用為此煩惱.. 解說一下範例,手機傳遞給Server後,Server收到參數,直接印出來,然後手機再將資料取回,非常的簡單流程 中間只有傳遞不處理任何資料.. Server side (C#) :

using System;

namespace EchoService
{
public partial class echoget : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString.Count > 0)
{
Response.Write(Server.UrlDecode(Request.QueryString.ToString()));
}else
{
//如果沒有資料,就傳似Json空物件
Response.Write("{}");
}
}
}
}

Android 傳遞方式:

//透過Get 方法 取得資料
//其中包含將中文字的部分自動進行 URL Encode
//確保字符的正確
public static String GetStringByURL(String urlPath) {
InputStream is = null;
String result = "";
try {
HttpClient httpclient = new DefaultHttpClient();
//下兩行就是為了處理,編碼問題,如果有中文部分這邊一次解決掉
URL url = new URL(urlPath);
URI uri = new URI(url.getProtocol(), url.getUserInfo(),
url.getHost(), url.getPort(), url.getPath(),
url.getQuery(), url.getRef());
HttpGet httpGet = new HttpGet(uri.toString());
httpGet.setHeader("Content-type",
"application/x-www-form-urlencoded; charset=utf-8");
HttpResponse response = httpclient.execute(httpGet);
HttpEntity entity = response.getEntity();
is = entity.getContent(); } catch (Exception e) {
result = "";
Log.e("WebUtil", "取資料時發生問題:" + e.toString());
}
// convert response to string
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result = sb.toString();
} catch (Exception e) {
result = "";
Log.e("WebUtil", "Error converting result " + e.toString());
} return result;
}

呼叫方式:

String result = WebUtil.GetStringByURL(http://swap.no2don.com/echoget.aspx?id=許當麻&age=29);

結果:

[C#] 與Android共舞–透過GET方式傳資料給Server(含解決中文編碼問題) (转帖)-LMLPHP
希望,有幫到你..

注意事項:
1.其中傳輸我都是透過格式為UTF-8
2.網路的Permission 記得打開  需要在 AndroidManifest.xml 中加入

<uses-permission android:name="android.permission.INTERNET"/>

3.還有一個地方需再Activity 中加入:

// AllowPolicy
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
