• java中post时中文乱码

    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;
    }
