To retrieve the body of the POST request sent to the handler, we'll use the @RequestBody annotation, and assign its value to a String. This takes the body of the request and neatly packs it into our fullName String. We've then returned this name back, with a greeting message.
There are two methods for reading the data in the body: getReader() returns a BufferedReader that will allow you to read the body of the request. getInputStream() returns a ServletInputStream if you need to read binary data.
Access Request Payload Details like HTTP method, request URL, headers, query and path parameters, and of course the request payload if available (and allowed). You can access all the information by using hapi's request object that is provided for each handler(request, reply) function.
The Request Payload - or to be more precise: payload body of a HTTP Request. is the data normally send by a POST or PUT Request. It's the part after the headers and the CRLF of a HTTP Request.
Simple answer:
Use getReader() to read the body of the request
More info:
There are two methods for reading the data in the body:
getReader() returns a BufferedReader that will allow you to read the body of the request.
getInputStream() returns a ServletInputStream if you need to read binary data.
Note from the docs: "[Either method] may be called to read the body, not both."
String payloadRequest = getBody(request);
Using this method
public static String getBody(HttpServletRequest request) throws IOException {
String body = null;
StringBuilder stringBuilder = new StringBuilder();
BufferedReader bufferedReader = null;
try {
InputStream inputStream = request.getInputStream();
if (inputStream != null) {
bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
char[] charBuffer = new char[128];
int bytesRead = -1;
while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {
stringBuilder.append(charBuffer, 0, bytesRead);
}
} else {
stringBuilder.append("");
}
} catch (IOException ex) {
throw ex;
} finally {
if (bufferedReader != null) {
try {
bufferedReader.close();
} catch (IOException ex) {
throw ex;
}
}
}
body = stringBuilder.toString();
return body;
}
You can use Buffer Reader from request to read
// Read from request
StringBuilder buffer = new StringBuilder();
BufferedReader reader = request.getReader();
String line;
while ((line = reader.readLine()) != null) {
buffer.append(line);
buffer.append(System.lineSeparator());
}
String data = buffer.toString()
Java 8 streams
String body = request.getReader().lines()
.reduce("", (accumulator, actual) -> accumulator + actual);
