It seems that some of our users have encountered an error code with getinputstream xml java servlet. This issue can occur due to several factors. Now let’s discuss some of them.

I have a useful servlet that receives XML data at a low cost. The below code works, but if I have wrong XML facts and throws the exception I want, you can still read the numbers and get the data from the correlation tag.

IOException response, httpservletresponse)

How do I get input stream from a servlet request?
If it was sent as raw, in the actual request body use ServletRequest#getInputStream(): InputStream xml = request.getInputStream(); // If sent as a standard application/x-www-form-urlencoded request parameter, use ServletRequest#getParameter():
You recently needed a project to get POST XML data fields. In a servlet, the request.And method call is logged with getinputstream() so that no data can be validated.
Below is the program for POST data: Java code
URLs
url = new url(urlBuf); HttpURLConnection httpurlconnection is equal to (HttpURLConnection) url .openConnection(); httpURLConnection.setDoOutput(true); httpURLConnection.setDoInput(true); httpURLConnection.setRequestMethod(“POST”); httpURLConnection.setConnectTimeout(5000); httpURLConnection.setReadTimeout(5000); httpURLConnection.connect(); BufferedWriter out = New buffered output writer (stream created (httpURLConnection.getOutputStream(), “GBK”)); out.write(word); out. flush();
= bufferedreader br BufferedReader(new new InputStreamReader((ServletInputStream)request.String getinputstream())); = Sb zero; stringbuilder = StringBuilder(); progressive time ((string = br.readLine())!=null) sb.append(string);
At first I thought it was aboutI stopped and debugged the cause, found out, but to no avail. After tracking, baidu’s opinions differ, and therefore there is no good solution. I am also inspired by this. uploading Finally, files are also processed on the servlet facade. The used component must inputStream. There is no situation, no it can not work here. Later it is flashed
