1. HttpURLConnection使用
private void sendRequestWithHttpUrl() {
new Thread(new Runnable() {
@Override
public void run() {
HttpURLConnection connection=null;
BufferedReader reader=null;
try {
URL url=new URL("https://www.baidu.com");
connection= (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setConnectTimeout(8000);
connection.setReadTimeout(8000);
InputStream inputStream=connection.getInputStream();
//对获取到的输入流楷书读取
reader=new BufferedReader(new InputStreamReader(inputStream));
StringBuilder response=new StringBuilder();
String line;
while ((line=reader.readLine())!=null){
response.append(line);
}
showResponse(line);
}catch (Exception e){
e.printStackTrace();
}finally {
if (reader!=null){
try {
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if (connection!=null){
connection.disconnect();
}
}
}
}).start();
}
private void showResponse(String line) {
runOnUiThread(new Runnable(){
@Override
public void run() {
//ui操作，结果显示到界面上
}
});
}
2.解析xml方式
3. json解析方式
4.回调机制开启子线程
public interface HttpCallBackListener{
void onFinish(String response);
void onFailure(Exception e);
}
private void sendRequestWithHttpUrl(String url, final HttpCallBackListener listener) {
new Thread(new Runnable() {
@Override
public void run() {
HttpURLConnection connection=null;
BufferedReader reader=null;
try {
URL url=new URL("https://www.baidu.com");
connection= (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setConnectTimeout(8000);
connection.setReadTimeout(8000);
InputStream inputStream=connection.getInputStream();
//对获取到的输入流楷书读取
reader=new BufferedReader(new InputStreamReader(inputStream));
StringBuilder response=new StringBuilder();
String line;
while ((line=reader.readLine())!=null){
response.append(line);
}
if (listener!=null){
listener.onFinish(line);
}
showResponse(line);
}catch (Exception e){
e.printStackTrace();
listener.onFailure(e);
}finally {
if (reader!=null){
try {
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if (connection!=null){
connection.disconnect();
}
}
}
}).start();
}
- 注：不论是使用HttpURLConnection还是okhttp,最终的回调接口还是在子线程中运行。
