[移动开发]Android通过HttpURLConnection 获取数据

下面是代码

GET

public class UrlHttpGet {
   public String getHttp(String path){
      String text=null;
      
      
      try {
         URL url=new URL(path);
         HttpURLConnection connection=(HttpURLConnection) url.openConnection();
         connection.setRequestMethod("GET");
         connection.setRequestProperty("Content-type", "application/x-www-form-urlencoded");
         connection.connect();
         if(connection.getResponseCode()==HttpURLConnection.HTTP_OK) {
            InputStream in=connection.getInputStream();
            BufferedReader br=new BufferedReader(new InputStreamReader(in,"UTF-8"));
            String s=null;
            StringBuffer sb=new StringBuffer();
            while((s=br.readLine())!=null) {
               sb.append(s);
            }
            br.close();
            text=sb.toString();
         }
      } catch (IOException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }
      return text;
      
   }
}

POST

public class UrlHttpPost {
   public String gerPost(String path,String body){
      String text=null;
      
      try {
         
         URL url=new URL(path);
         HttpURLConnection connetcion =(HttpURLConnection) url.openConnection();
         connetcion.setRequestMethod("POST");
         
         connetcion.setDoOutput(true);
         connetcion.setDoInput(true);
         connetcion.setUseCaches(false);
         
         connetcion.setRequestProperty("Content-type", "application/json;charset=utf-8");
         connetcion.connect();
         
         StringBuffer sb=new StringBuffer();

         
         OutputStream bw=connetcion.getOutputStream();
         bw.write(body.getBytes());
         bw.close();
      
         
         String t=null;
         int a=connetcion.getResponseCode();
         if(a==HttpURLConnection.HTTP_OK) {
            BufferedReader br=new BufferedReader(new InputStreamReader(connetcion.getInputStream(),"utf-8"));
            while((t=br.readLine())!=null) {
               sb.append(t);
            }
            text=sb.toString();
            
            
         }
      } catch (IOException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }
      return text;
   }
}

PUT

public class UrlHttpPut {

   public String setPut(String path,String body) {
      String text=null;
      try {
         URL url=new URL(path);
         HttpURLConnection connection=(HttpURLConnection) url.openConnection();
         connection.setRequestMethod("PUT");
         
         connection.setRequestProperty("Content-type", "application/JSON;charset=utf-8");
         connection.setRequestProperty("Authorization", "TOKEN");
         connection.setDoInput(true);
         connection.setDoOutput(true);
         connection.setUseCaches(false);
         connection.setReadTimeout(5000);
         connection.connect();
         
         OutputStream os=connection.getOutputStream();
         os.write(body.getBytes());
         os.flush();
         os.close();
         String str=null;
         StringBuffer sb=new StringBuffer();
         if(connection.getResponseCode()==HttpURLConnection.HTTP_OK) {
            BufferedReader br=new BufferedReader(new InputStreamReader(connection.getInputStream(),"utf-8"));
            
            while((str=br.readLine())!=null) {
               sb.append(str);
            }
            br.close();
         }
         text=sb.toString();
         System.out.println(text);
      } catch (IOException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }
      return text;
   }
}
