Android如何在http頭信息裡設置參數

在使用http請求server時常常要傳遞一些參數給server，如IMEI號、平台號、渠道號、客戶端的版本號等一些通用信息，像這些參數我們沒有必要每次都拼在url後，我們可以統一添加到http頭裡。

1.HttpClient的設置http頭的參數

	 HttpClient httpclient = new DefaultHttpClient();

	 httpclient.getParams().setParameter(
	 CoreConnectionPNames.CONNECTION_TIMEOUT, CONN_TIME_OUT);
	 HttpGet httpget = new HttpGet(url);
	 httpget.addHeader("version", SystemInfo.getVersionChars());
	 httpget.addHeader("client_token", SystemInfo.getIMEI());
	 httpget.addHeader("platform", SystemInfo.getPlatForm() + "");
	 httpget.addHeader("channel_id", SystemInfo.getChannelId() + "");

2.HttpURLConnection的設置http頭的參數

httpURLConnection.addRequestProperty("version",
				SystemInfo.getVersionChars());
		httpURLConnection.addRequestProperty("client_token",
				SystemInfo.getIMEI());
		httpURLConnection.addRequestProperty("platform",
				SystemInfo.getPlatForm() + "");
		httpURLConnection.addRequestProperty("channel_id",
				SystemInfo.getChannelId() + "");

	httpURLConnection.setRequestProperty("version",
				SystemInfo.getVersionChars());
		httpURLConnection.setRequestProperty("client_token",
				SystemInfo.getIMEI());
		httpURLConnection.setRequestProperty("platform",
				SystemInfo.getPlatForm() + "");
		httpURLConnection.setRequestProperty("channel_id",
				SystemInfo.getChannelId() + "");
