java与c通讯

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();
