Android通过http方式获取JSON字符串并解析的注意事项(乱码,小黑框)

在windows平台下换行符是 /r/n ,而在linux,android平台下换行符是 /n ,所以取得的JSON字符串必须进行过滤,将/r/n替换成/n,

另外不建议使用 BasicResponseHandler() ,这样会导致乱码

两个重要函数:

public static String get(String urlString)  {/*try{HttpGet request = new HttpGet(urlString);String result=getHttpClient().execute(request,new BasicResponseHandler());return result;}catch(IOException e){throw e;}*/String result="";BufferedReader in=null;try {    HttpClient client = new DefaultHttpClient();    HttpGet request=new HttpGet(urlString);    HttpResponse response = client.execute(request);        in=new BufferedReader(new InputStreamReader(response.getEntity().getContent()));    StringBuffer sb=new StringBuffer("");    String line="";    String NL=System.getProperty("line.separator");   // String NL="";    while((line=in.readLine())!=null){    sb.append(line+NL);    }    in.close();    result=sb.toString();    result=JsonFilter(result);} catch (Exception e) {e.printStackTrace();}finally{if(in!=null){try{in.close();}catch(IOException e){e.printStackTrace();}}}return result;}/* * 对json字符串进行过滤,防止乱码和黑框 */public static String JsonFilter(String jsonstr){return jsonstr.substring(jsonstr.indexOf("{")).replace("\r\n","\n"); }
