No response after putting in Header in request


By : Dave McLeary
Date : October 17 2020, 08:10 PM
it should still fix some issue i think you shouldn't place the getHeader() inside the constructor of JsonObjectRequest. It should be placed inside the anonymous class block
code :
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(
        Request.Method.GET, 
        url, 
        null, 
        new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                Log.d("Login Response:", response.toString());
                JSONObject responseOject = response;
                if(responseOject.has("response")){
                    try {
                        Log.d("Data Response", responseOject.getString("response"));
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }else if(responseOject.has("error")){
                    try {
                        errorMessage = responseOject.getString("error");
                        new AlertDialog.Builder(MainActivity.this)
                                .setTitle("Error")
                                .setMessage(errorMessage)
                                .setNegativeButton("OK", null)
                                .show();
                     } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }else{
                    //Server error. Come back again later
                }
            }
        },
        new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.e("Error at login: ", error.getMessage());
            }
        }
){
       @Override
       public Map<String, String> getHeaders() throws AuthFailureError {
            HashMap<String, String> headers = new HashMap<String, String>();
            headers.put("Content-Type", "application/json");
            headers.put("Authorization", "Bearer DGZjaza3saxL98g9ATRUQsolCxEZPBUd");
            return headers;
       }
};

Does a success response header without response body cause an error in an AJAX request?


By : Rene
Date : March 29 2020, 07:55 AM
I hope this helps you . Using AJAX to check for server connectivity , Note Not tried node.js, node.js pieces not addressed
Edit
code :
 'Content-Type': 'text/plain'
dataType: "json"
<p id="results"></p>
<button>localpost</button>
$(function() {

var localpost = function() {    

var callback = function(name) {
                 $("#results").html(name)
               }; 

var request = $.ajax({
    url : "/echo/json/",
    type:"POST",
    dataType: "json",
    data: { json : [] },
    statusCode : {
    200: function (data, textStatus, jqxhr) {
            if (textStatus === "success" 
               && jqxhr.getResponseHeader("Content-Length") === (0 || null)) {
               alert(textStatus
               +"\nCould not connect to the server! Returning to login screen.");

               callback("textStatus: "
               + textStatus+"<br />jqxhr status: " +j qxhr.state()
               + "<br />content-length : " 
               + jqxhr.getResponseHeader("Content-Length")
               + "<br />status : "+jqxhr.status);
       // signOut();
            };

    }
  }
});
        // `success` callback
request.then(function(data, textStatus, jqxhr) {
    if (textStatus === "success") {
        // DoStuff()
       console.log(textStatus);
    };  
},
        // `error` callback
  function(jqxhr, textStatus, errorThrown) {
    if (textStatus != "success") {
        // DoStuff()
       console.log(errorThrown);
    };  
})
};

    $("button").on("click", localpost);
    // localpost()    

});

Websocket protocol request header and response header no content type


By : Kurt N. Van Ness
Date : March 29 2020, 07:55 AM
seems to work fine HTTP Content-Type header is meaningless for WebSocket connection.
WebSockets use HTTP only for initial handshake and after WebSocket connection is initialized WebSockets transfers binary or text messages which content type is application defined.

Set response header and request header for cross domain file upload


By : Amri Papanya Amiira
Date : March 29 2020, 07:55 AM
it fixes the issue You have to add X-File-Name, X-File-Size and X-File-Type to the list of headers:
code :
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, X-File-Name, X-File-Size, X-File-Type");

How does Cache-Control effect in Request header, compared with in Response header


By : Injamamul Karim
Date : March 29 2020, 07:55 AM
this will help Does that mean in the 100 seconds, subsequent requests will never request to server? All these requests just receive a response in cache?
Unless subsequent requests use Cache-Control header for more control on cache, Yes, the requests will just get response data from cache.
code :
var poll = function() {
  $.ajax({
    url: '/poll',
    beforeSend: function(xhr) {
      //xhr.setRequestHeader('Cache-Control', 'no-cache');
      //xhr.setRequestHeader('Cache-Control', 'max-age=0');
    },
    success: function(){
      setTimeout(poll, 5000);
    }
  });
}
poll();
http.createServer(function(req,res) {
  ...
  // if request path is /poll
  res.setHeader('Cache-Control', 'max-age=18');
  res.end();
})

Modify request header going into a controller and response header leaving a Spring Boot RestController


By : Sunit Kumar Panda
Date : March 29 2020, 07:55 AM
like below fixes the issue You can still use HandlerInterceptor. Create your class implementing HandlerInterceptor (or extending HandlerInterceptorAdapter), and then register it using another class which extends WebMvcConfigurer.
code :
@EnableWebMvc
@Configuration
@ComponentScan
public class MyWebConfig implements WebMvcConfigurer {
    public void addInterceptors(InterceptorRegistry registry) {
         registry.addInterceptor(new [...]); //Apply to all controllers
         registry.addInterceptor(new [...]).addPathPatterns("path1","path2"); //Apply to specific paths to restrict to some controllers.
    }
}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) {
    [...]
    HttpServletRequestWrapper decryptedRequest = new HttpServletRequestWrapper((HttpServletRequest) request) {
       public String getHeader(String name) {
            if (name.equals("DecryptedHeader")) {
                  String encrypted = super.getHeader("EncryptedHeader");
                  String decrypted = decrypt(encrypted);
                  return decrypted;
            }
            return super.getHeader(name); //Default behavior
       }
   }


   chain.doFilter(decryptedRequest, response); //Pass on the custom request down
}
