1.HttpURLConnection
public class HttpURLConnectionGetAndPost {
private String urlAddress = "xxxx";
public void doGet(String method, String s) throws IOException {
String getUrl = urlAddress + method + "?sex=" + s;
URL url = new URL(getUrl);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();

Log.d("test", sb.toString());
} else {

2.HttpClient
public class HttpClientGetAndPost {
private String urlAddress = "xxxx";
private void doGet(String method, String s){
String getUrl = urlAddress+ method + "?sex= "+ s;
HttpGet httpGet = new HttpGet(getUrl);
try {
HttpResponse httpResponse = new DefaultHttpClient().execute(httpGet);
if(httpResponse.getStatusLine().getStatusCode() ==200){
String result = EntityUtils.toString(httpResponse.getEntity());
Log.d("test","result="+result);
}else{
Log.d("test","get failed");
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
/// HttpPost
}
private void doPost(String method, String s) throws ClientProtocolException, IOException{
HttpPost httpPost = new HttpPost(urlAddress+method);
List<NameValuePair> parms = new ArrayList<NameValuePair>();
parms.add(new BasicNameValuePair("sex",s) );
httpPost.setEntity(new UrlEncodedFormEntity(parms,HTTP.UTF_8));
HttpResponse httpResponse = new DefaultHttpClient().execute(httpPost);
if(httpResponse.getStatusLine().getStatusCode() ==200){
String result = EntityUtils.toString(httpResponse.getEntity());
Log.d("test","result="+result);
}else{
Log.d("test","post failed");
}
}
}
3. OKHttp3
public class OkHttpGetAndPost {
private String urlAddress = "xxxx";
private OkHttpClient okHttpClient = new OkHttpClient();
private void doGet(String method, String s) throws IOException {
String url = urlAddress + method + "?sex=" + s;
Request request = new Request.Builder().url(url).get().build();
Response respone = okHttpClient.newCall(request).execute();
if (respone.isSuccessful()) {
Log.d("test", respone.body().string());
} else {
Log.d("test", "get failed");
}
}
private void doPost(String method, String s) {
FormBody formBody = new FormBody.Builder().add("sex", s).build();
RequestBody body = RequestBody.create(MediaType.parse("application/json; charset=utf-8"), "{\"sex\",\""+s+"\"}");
Request request = new Request.Builder().url(urlAddress + method).post(body).build();
okHttpClient.newCall(request).enqueue(new Callback() {
@Override
public void onResponse(Call arg0, Response arg1) throws IOException {
Log.d("test", arg1.body().string());
}
@Override
public void onFailure(Call arg0, IOException arg1) {
Log.d("test", "post failed");
}
});
}
}
由以上demo可以看出，OKHttp使用最简单方便，代码书写量少，而且网络请求高效。
