Issue
I'm making a PUT request using OkHttp 4.9.1 from my Android app as below,
RequestBody reqBody = new FormBody.Builder()
.add("name", name)
.add("phone", phone)
.build();
Request request = new Request.Builder()
.url(API_URL)
.put(reqBody)
.build();
new OkHttpClient().newCall(request).enqueue(new Callback() {
...
});
The request comes to the server but the problem is I cannot access the parameters from the Servlet,
@Override
protected void doPut(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
System.out.println("NAME: " + req.getParameter("name"));
System.out.println("PARAMS: " + new HashMap(req.getParameterMap()).toString());
System.out.println("CT: " + req.getContentType());
}
below is the output log from the server,
NAME: null
PARAMS: {}
CT: application/x-www-form-urlencoded
As you can see the parameter map is empty. What am I missing?
Solution
request.getParameter() is not working in Servlets when it comes to PUT requests. So this was not a problem with OkHttp. As to why request.getParameter() is not working in doPut(...) refer the post below,
Servlet request.getParameter() returns null in PUT but not in POST
