android为HttpClient和HttpURLConnection添加中国移动代理
在android中,一般需要联网的时候前,都要做一次网络的判断,判断当前的网络状态!然后开始请求网络
当我们使用wap网络的时候,程序中必须要中国移动代理!这样的话,手机才能正常的访问internet!
在android中,有两种方式请求网络:HttpURLConnection和HttpClient请求方式,如果网络状态为wap的时候,都要为两种请求添加中国移动代理的!
第一种方式:HttpURLConnection

* @param context context对象
* @param requestUrl 请求的URL
* @param param 请求的参数
* @return 返回一个inputstream流
*/
public static InputStream getHttpURLConnectionInputStream(Context context,String requestUrl,Map<String, String> param) {
URL url;
HttpURLConnection conn = null;
InputStream input = null;
try {
url = new URL(requestUrl);
if(getAPNType(context)==NetWorkUtil.CMWAP) //当请求的网络为wap的时候,就需要添加中国移动代理
{
Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress("10.0.0.172", 80));
conn = (HttpURLConnection) url.openConnection(proxy);
}
conn = (HttpURLConnection) url.openConnection();
conn.setConnectTimeout(10000); //请求超时
conn.setRequestMethod("POST"); //请求方式
conn.setReadTimeout(1000); //读取超时
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setRequestProperty("Charset", "UTF-8");
conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
OutputStream os = conn.getOutputStream();
StringBuilder sb = new StringBuilder();
Iterator<String> it = param.keySet().iterator();
while (it.hasNext()) {
String key = it.next();
String value = param.get(key);
sb.append(key).append("=").append(value).append("&");
}
String p = sb.toString().substring(0, sb.length()-1);
System.out.println("请求的参数"+p);
os.write(p.getBytes("utf-8"));
os.close();
if(conn!=null)
{
input = conn.getInputStream();
}
} catch (Exception e) {
e.printStackTrace();
}
return input;
}
上面这种方式就是HttpURLConnection ,这种方式在android开发中也是比较常用的,希望朋友们也要熟悉的掌握!
第二种方式:HttpClient
/**

* @param requestUrl 请求的URL

public static InputStream getHttpClientInputStream(Context context,String requestUrl, Map<String, String> param)throws Exception {
HttpClient client = new DefaultHttpClient();
if(getAPNType(context)==NetWorkUtil.CMWAP) //当请求的网络为wap的时候,就需要添加中国移动代理
{
HttpHost proxy = new HttpHost("10.0.0.172", 80);
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,
proxy);

HttpPost hp = new HttpPost(requestUrl);
hp.setHeader("Charset", "UTF-8");
hp.setHeader("Content-Type", "application/x-www-form-urlencoded");
List<BasicNameValuePair> list = new ArrayList<BasicNameValuePair>();
Iterator<String> it = param.keySet().iterator();
while (it.hasNext()) {
String key = it.next();
list.add(new BasicNameValuePair(key, param.get(key)));
}
hp.setEntity(new UrlEncodedFormEntity(list,"UTF-8"));
HttpResponse response = null;
response = client.execute(hp);
