近有个项目下需要接收POST过来的XML数据包,在struts中的Action方法中,调用request.getInputStream() 发现无法读到任何数据。 以下是POST数据的程序代码: 代码
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();
view plaincopy to clipboardprint?
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.setRequestMethod("POST"); httpURLConnection.setConnectTimeout(5000);
httpURLConnection.setReadTimeout(5000);
httpURLConnection.connect();
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(
httpURLConnection.getOutputStream(), "GBK"));
out.write(word);
out.flush();这个是读取程序代码: 代码
BufferedReader br = new BufferedReader(new InputStreamReader((ServletInputStream)request.getInputStream()));
String line = null;
StringBuilder sb = new StringBuilder();
while((line = br.readLine())!=null){
sb.append(line);
}
view plaincopy to clipboardprint?
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);
}开始还以为是犯了什么低级错误,不断调试查找原因,无果。baidu上搜索了下,众说纷纭,也没有很好的解决方案。我也左思右想,文件上传也是在Action立面处理的,组件肯定用到inpputStream一点问题没有,没可能这里不行,后来灵光一闪,在POST程序中加入: Java代码
httpURLConnection.setRequestProperty("content-type", "text/html");
view plaincopy to clipboardprint?
httpURLConnection.setRequestProperty("content-type", "text/html");
httpURLConnection.setRequestProperty("content-type", "text/html");,测试成功! 根据以上现象,我们不难看出struts对没有指定content-type的request请求,封装时候作了一些处理,导致无法在Action中获取request.getInputStream() 和 request.getReader()。
