request.getInputStream() 的两种解析方式

request 内容解析方式：

方式一：

byte[] bytes = new byte[1024 * 1024];InputStream is = request.getInputStream();int nRead = 1;int nTotalRead = 0;while (nRead > 0) {nRead = is.read(bytes, nTotalRead, bytes.length - nTotalRead);if (nRead > 0)nTotalRead = nTotalRead + nRead;}String str = new String(bytes, 0, nTotalRead, "utf-8");System.out.println("Str:" + str);

?方式二：

BufferedReader br = new BufferedReader(new InputStreamReader((ServletInputStream) request.getInputStream()));String line = null;StringBuilder sb = new StringBuilder();while ((line = br.readLine()) != null) {sb.append(line);}System.out.println(sb);

头参数解析方式

?

String params = request.getQueryString();private Map getRequestParam(String params){Map paramMap = null;if(null!=params){paramMap = new HashMap();String param[]=params.split("&");        for(int i=0;i<param.length;i++){        String content = param[i];        String key = content.substring(0, content.indexOf("="));        String value = content.substring(content.indexOf("=")+1, content.length());       paramMap.put(key, value);        }}return paramMap;}
