Java解析在http等协议中传输json格式的InputStream流

在协议传输的json格式数据一般都会是用“=”“&”作为分隔:例如:“ type=online&mode=5&plate_num= 京 A12345&plate_color= 蓝 色
&plate_val=true&confidence=25&car_logo= 丰 田 &car_color= 白 色 &vehicle_type= 轿 车”
这里提供了解析的方法:

public static Map<String,String> formData2Dic(String formData ) {
    
    
        Map<String,String> result = new HashMap<>();
        if(formData== null || formData.trim().length() == 0) {
    
    
            return result;
        }
        final String[] items = formData.split("&");
        Arrays.stream(items).forEach(item ->{
    
    
            final String[] keyAndVal = item.split("=");
            if( keyAndVal.length == 2) {
    
    
                try{
    
    
                    final String key = URLDecoder.decode( keyAndVal[0],"utf8");
                    final String val = URLDecoder.decode( keyAndVal[1],"utf8");
                    result.put(key,val);
                }catch (UnsupportedEncodingException e) {
    
    }
            }
        });
        return result;
    }

调用:

               //获得查询字符串(get)
//                String queryString =  exchange.getRequestURI().getQuery();
                //获得表单提交数据(post)
                String postString = IOUtils.toString(httpExchange.getRequestBody(), Charset.forName("UTF-8"));
                Map<String,String> postInfo = formData2Dic(postString);
                for (String key : postInfo.keySet()) {
    
    
                    Object value = postInfo.get(key);
                    System.out.println(key + ":" + value);
                }
