服務器端的使用:json
String jsonString=""; String action_flag=request.getParameter("action_flag"); if(action_flag=request.getParameter("action_flag")); { jsonString=JsonTools.createJsonString("person",service.getPersin); //經過使用JsonTools工具類把數據封裝成String串 }
客戶端Json數據的解析
寫一個HttpUtils工具類服務器
public static String getJsonContent(String url_path){ try{ URL url=new URL(url_path); HttpURLConnection connection=(HttpURlConnection) url.openConnection(); connection.setConnectTimeout(3000); connection.setRequestMethod("GET"); connection.setDoInput(true); int code=connection.getResponseCode(); if(code==200){ return changeInputStream(InputStream inputStream);; } } } public static String changeInputStream(InputStream inputStream){ String jsonString=""; ByteArrayOutPutStream outputStream=new ByteArrayoutPutStream(); int len=0; byte[] data=new byte[1024]; try{ while((len=InputStream.read(data))!=0){ outputStream.write(data,0,len); } jsonString=new String(outputStream.toByteArray()); } }
經過使用JsonObject類或者是JsonArray來解析Json字符串markdown
public class JsonTools{ public static Person getPerson(String key,String jsonString){ try{ JSONObject jsonObject=new JSONObject(jsonString); JSONObject personObject=jsonObject.getJSONObject("person"); person.setname(personObject.getString("name")); } } }
