Java Http请求传json数据乱码问题的解决
业务场景:调easyui的dialog打开一个弹窗,传参是用json封装的,而且有中文,然后在极速模式是正常的,在ie11测试发现中文出现乱码了
var params = JSON.stringify(writParamList); top.dialog({ id: 'noticeList', title:'列表', width:900, height:500, url:'${root}/notice/multiNoticeList.do?params='+params, onclose:function(){ //location.reload(); } }).showModal();
后台获取json数据,并转成list,然后在ie模式,获取到的json数据都出现中文乱码,然后导致json不能解析报错了
String params = request.getParameter("params"); logger.info("文书参数转换前:》》"+params); params=StringEscapeUtils.unescapeJava(params); logger.info("文书参数转换后:》》"+params); ObjectMapper mapper = new ObjectMapper(); JavaType javaType = mapper.getTypeFactory().constructParametricType(List.class, ApprWritUnionFormModel.class); /*List<FormModel> writUnionFormList = JSON.parseArray(params, FormModel.class);*/ List<FormModel> writUnionFormList=new ArrayList<FormModel>(); try { writUnionFormList = (List<FormModel>)mapper.readValue(params, javaType); } catch (JsonParseException e) { e.printStackTrace(); } catch (JsonMappingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }
针对上面问题,和同事讨论,最开始打算base64加密来传,然后发现base64加密中文出现问题,所以改成URLEncode的方式,前端加密两遍,后台在解密一遍
var params = JSON.stringify(writParamList); top.dialog({ id: 'noticeList', title:'列表', width:900, height:500, url:'${root}/notice/multiNoticeList.do?params='+encodeURI(encodeURI(params)), onclose:function(){ //location.reload(); } }).showModal();
后台代码修改,解码一遍,然后发现在ie也正常
String params = request.getParameter("params"); logger.info("文书参数转换前:》》"+params); //params=StringEscapeUtils.unescapeJava(params); // byte[] buffer=Base64Utils.decodeFromString(params); // params = new String(buffer); try { params=URLDecoder.decode(params,"utf-8"); } catch (UnsupportedEncodingException e1) { e1.printStackTrace(); } logger.info("文书参数转换后:》》"+params); ObjectMapper mapper = new ObjectMapper(); JavaType javaType = mapper.getTypeFactory().constructParametricType(List.class, ApprWritUnionFormModel.class); /*List<FormModel> writUnionFormList = JSON.parseArray(params, FormModel.class);*/ List<FormModel> writUnionFormList=new ArrayList<FormModel>(); try { writUnionFormList = (List<FormModel>)mapper.readValue(params, javaType); } catch (JsonParseException e) { e.printStackTrace(); } catch (JsonMappingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }
