java获取接收POST过来的XML数据包，使用request.getInputStream() 和 request.getReader()

struts2 Action中获取request, response对象的方法

ActionContext ctx = ActionContext.getContext();

HttpServletRequest request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST);

HttpServletResponse response = (HttpServletResponse)ctx.get(ServletActionContext.HTTP_RESPONSE);

//ServletActionContext.APPLICATION;

//ServletActionContext.SESSION;

//ServletActionContext.PAGE_CONTEXT;

struts2 中使用request.getInputStream()获取POST数据

BufferedReader br = new BufferedReader(new InputStreamReader((ServletInputStream)request.getInputStream()));

String line = null;

StringBuilder sb = new StringBuilder();

while((line = br.readLine())!=null){

sb.append(line);

}

BufferedReader br = new BufferedReader(new InputStreamReader((ServletInputStream)request.getInputStream()));

String line = null;

StringBuilder sb = new StringBuilder();

while((line = br.readLine())!=null){

sb.append(line);

}

java的post

URL url = new URL(urlBuf);

HttpURLConnection httpURLConnection = (HttpURLConnection) url

.openConnection();

httpURLConnection.setDoOutput(true);

httpURLConnection.setDoInput(true);

httpURLConnection.setRequestMethod("POST"); httpURLConnection.setConnectTimeout(5000);

httpURLConnection.setReadTimeout(5000);

httpURLConnection.connect();

BufferedWriter out = new BufferedWriter(new OutputStreamWriter(

httpURLConnection.getOutputStream(), "GBK"));

out.write(word);

out.flush();

URL url = new URL(urlBuf);

HttpURLConnection httpURLConnection = (HttpURLConnection) url

.openConnection();

httpURLConnection.setDoOutput(true);

httpURLConnection.setDoInput(true);

httpURLConnection.setRequestProperty("content-type", "text/html");

httpURLConnection.setRequestMethod("POST");httpURLConnection.setConnectTimeout(5000);

httpURLConnection.setReadTimeout(5000);

httpURLConnection.connect();

BufferedWriter out = new BufferedWriter(new OutputStreamWriter(

httpURLConnection.getOutputStream(), "GBK"));

out.write(word);

out.flush();
