设置流的编码,就避免了乱码
public static String post(String path,String params) throws Exception{ HttpURLConnection httpConn=null; BufferedReader in=null; //PrintWriter out=null; try { URL url=new URL(path); httpConn=(HttpURLConnection)url.openConnection(); httpConn.setRequestMethod("POST"); httpConn.setDoInput(true); httpConn.setDoOutput(true); System.out.print("params="+params); //utf-8 PrintWriter ot = new PrintWriter(new OutputStreamWriter(httpConn.getOutputStream(),"utf-8")); ot.println(params); ot.flush(); //out=new PrintWriter(httpConn.getOutputStream()); //out.println(params); //out.flush(); //读取响应 if(httpConn.getResponseCode()==HttpURLConnection.HTTP_OK){ StringBuffer content=new StringBuffer(); String tempStr=""; //utf-8 in=new BufferedReader(new InputStreamReader(httpConn.getInputStream(),"utf-8")); while((tempStr=in.readLine())!=null){ content.append(tempStr); } return content.toString(); }else{ throw new Exception("请求出现了问题!"); } } catch (IOException e) { e.printStackTrace(); }finally{ in.close(); // out.close(); httpConn.disconnect(); } return null; }
