how to use PostgreSQL mod for vertx in js? - javascript

hi im new in vertx and i want use https://github.com/vert-x/mod-mysql-postgresql for a service
i use this code for my web server
var vertx = require('vertx');
var console = require('vertx/console');
var Server = vertx.createHttpServer();
Server.requestHandler(function (req) {
var file = req.path() === '/' ? 'index.html' : req.path();
if (file === '/foo') {
foo(req);
}
else{
req.response.sendFile('html/' + file);
}
}).listen(8081);
function foo(req) {
req.bodyHandler(function (data) {
//data is json {name:foo, age:13} i want insert this in any table in postgre
//do
var dataresponse= messagefrompostgre;//e: {status:"ok", code:200, message: "its ok"}
req.response.putHeader("Content-Type", "application/json");
req.response.end(dataresponse);
});
}
and this is my event click button
$.ajax({
data: {name:foo, age:13} ,
url: '/foo',
type: 'post',
dataType: 'json',
complete: function (response) {
alert(JSON.stringify(response));
}
});

I found how to do it:
var vertx = require('vertx');
var console = require('vertx/console');//TODO: remove
var eventBus = vertx.eventBus;
var Server = vertx.createHttpServer();
Server.requestHandler(function (req) {
var file = req.path() === '/' ? 'index.html' : req.path();
if (file === '/foo') {
foo(req);
}
else{
req.response.sendFile('html/' + file);
}
}).listen(8081);
function foo(req) {
req.bodyHandler(function (data) {
//data is json {name:foo, age:13}
var jsona={
"action" : "raw",
"command" : "select * from test"
}
eventBus.send("PostgreSQL-asyncdb",jsona, function(reply) {
req.response.putHeader("Content-Type", "application/json");
req.response.end(JSON.stringify(reply));
});
});
}
and this return:
{"message":"SELECT 6","rows":6,"fields":["testt"],"results":[["lol"],["lolŕ"],["lol2"],["lol2"],["testlol"],["testlolp"]],"status":"ok"}

Is there any better way to display POST request in Angular Js

I have used both PUT and POST request to modify and create a data. But the thing is POST request is not working properly. When i click on add() button , automatically POST request is generating id in the json-data before filling the information in the text fields.
Moreover data should be updated when I click on the save() button . Below I have pasted my code, if I have made any mistake tel me know and I appreciate every one whomever gives any information.
HTMl :
<button class="btn btn-info" ng-click="addmode()"> Add </button>
<button class="btn btn-success" ng-show="editMode" ng-click="saveinfo()"> Save </button>
Angular JS :
$scope.addmode = function(information) {
var postinfo = information;
$http({
url:'http://localhost:3000/contacts' ,
method : 'POST',
data : postinfo
})
.then(
function successCallback(response) {
$scope.selectedcontact = '';
console.log(response.data)
},
function errorCallback(response) {
console.log("Error : " + response.data);
});
};
First create services/api.js
angular.module('app')
.factory('api', function ($rootScope,ApiEndpoint, $http, $q,$timeout,$cookies) {
var get = function (url) {
var config = {url: url, method: ApiEndpoint.Methods.GET};
return this.call(config);
};
var del = function (url) {
var config = {url: url, method: ApiEndpoint.Methods.DELETE};
return this.call(config);
};
var post = function (url, data) {
var config = {url: url, method: ApiEndpoint.Methods.POST, data: data};
return this.call(config);
};
var put = function (url, data) {
var config = {url: url, method: ApiEndpoint.Methods.PUT, data: data};
return this.call(config);
};
return {call: call, get: get, post: post, del: del, put: put};
});
After create service/apiendpoint.js
angular.module('app')
.constant('ApiEndpoint', {
ServerUrl: 'http://localhost/',
BaseUrl: 'http://localhost/',
Methods: {GET: 'GET', POST: 'POST', PUT: 'PUT', DELETE: 'DELETE'},
Models: {
test:"fe_api/test",
},
URLS: {
QUERY: 'app/'
},
getUrl: function (url) {
var host=window.location.host;
var protocol=window.location.protocol ;
return protocol+"//"+host+"/"+url;
}
});
**Create model handler **
angular.module('app')
.factory('ApiService', function (api, ApiEndpoint) {
var getModel = function (url_part)
{
var url = ApiEndpoint.getUrl(ApiEndpoint.URLS.QUERY) + url_part;
return api.get(url);
};
var getModelViaPost = function (url_part, data)
{
var url = ApiEndpoint.getUrl(ApiEndpoint.URLS.QUERY) + url_part;
return api.post(url, data);
};
var postModel = function(model_name, data) {
var url = ApiEndpoint.getUrl(ApiEndpoint.URLS.QUERY) + model_name;
return api.post(url, data);
};
var putModel = function(model_name, data) {
var url = ApiEndpoint.getUrl(ApiEndpoint.URLS.QUERY) + model_name;
return api.put(url, data);
};
var deleteModel = function(model_name, id) {
var url = ApiEndpoint.getUrl(ApiEndpoint.URLS.QUERY) + model_name + '/' + id;
return api.delete(url);
};
return {
getModel: getModel,
postModel : postModel,
putModel : putModel,
deleteModel : deleteModel,
getModelViaPost : getModelViaPost
};
});
write API call in the controller
var data = {
wut_token: $cookies.data,
};
ApiService.postModel(ApiEndpoint.Models.test, data).then(function (response) {
if (response.SUCCESS == "FALSE") {
} else {
}
})

Laravel 5.3 AJAX login doesn't redirect

I have similar issue like this one.
I'm trying to make AJAX login using Laravel 5.3 Auth.
Here's what I got so far:
var login = function()
{
var data = {};
data["email"] = $('#email').val();
data["password"] = $('#password').val();
if($('#remember').is(':checked'))
data["remember"] = "on";
$.ajax({
type: "POST",
url: '/login',
data: JSON.stringify(data),
// data: data,
headers : { 'Content-Type': 'application/json' },
success: function(data) {
console.log(data);
// window.location.href = "/dashboard";
}
});
};
I'm sending CRSF token as X-CSRF-TOKEN header.
The problem is that when I successfully login, I say on the same page,
but in Network tab I can see that /dashboard page is loaded by I'm not
redirected.
In the same manner, when I pass wrong credentials, I stay on the same page,
but I can see that /login page is loaded in the separate call with an error message that should be actually displayed.
Also, I've tried without headers : { 'Content-Type': 'application/json' },
and sending data as: data = data, but I get the same thing.
Why the browser doesn't redirect to that page since it is loading it in the "background"?
Edit: I'm getting correct page as request response as well, I can see it
in console (console.log(data);).
//Login FORM
$(document).on('submit', 'form#FormID', function(e) {
e.preventDefault();
var forms = document.querySelector('form#FormID');
var request = new XMLHttpRequest();
var formDatas = new FormData(forms);
request.open('post','/login');
request.send(formDatas);
request.onreadystatechange = function() {
if (request.readyState === 4) {
if (request.status === 200) {
if (request.responseText == 'success') {
setTimeout(function() {
window.location.href = "/dashboard";
}, 5000);
}else{
};
}
}
}
});
//Controller
public function authUser(Request $request){
$data = $request->except('_token');
$validate = \Validator::make($data, [
'email' => 'email'
]);
if ($validate->fails())
return 'Invalid email format for username.';
if (\Auth::attempt($data)) {
return 'success';
}else{
return 'Invalid username or password';
}
}
//Route
Route::post('/login', 'YourController#authUser');
The problem might be with the response AJAX request is expecting before redirect.
Try the above code.
in the controller method
function login(Request $request){
if(\Auth::attempt($request)){
return response()->json('success');
}else{
return response()->json('wrong username or pass', 401);
}
}
in ajax
$.ajax({
type: "POST",
url: '/login',
data: JSON.stringify(data),
// data: data,
headers : { 'Content-Type': 'application/json' },
success: function(data) {
console.log(data);
window.location.href = "/dashboard";
},
error : function(data){
alert(data);
}
});
Here's an interesting solution.
/**
* Get the failed login response instance.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
protected function sendFailedLoginResponse(Request $request)
{
if ($request->ajax()) {
return response()->json([
'error' => Lang::get('auth.failed')
], 401);
}
return redirect()->back()
->withInput($request->only($this->username(), 'remember'))
->withErrors([
$this->username() => Lang::get('auth.failed'),
]);
}
And this:
var loginForm = $("#loginForm");
loginForm.submit(function(e) {
e.preventDefault();
var formData = loginForm.serialize();
$('#form-errors-email').html("");
$('#form-errors-password').html("");
$('#form-login-errors').html("");
$("#email-div").removeClass("has-error");
$("#password-div").removeClass("has-error");
$("#login-errors").removeClass("has-error");
$.ajax({
url: '/login',
type: 'POST',
data: formData,
success: function(data) {
$('#loginModal').modal('hide');
location.reload(true);
},
error: function(data) {
console.log(data.responseText);
var obj = jQuery.parseJSON(data.responseText);
if (obj.email) {
$("#email-div").addClass("has-error");
$('#form-errors-email').html(obj.email);
}
if (obj.password) {
$("#password-div").addClass("has-error");
$('#form-errors-password').html(obj.password);
}
if (obj.error) {
$("#login-errors").addClass("has-error");
$('#form-login-errors').html(obj.error);
}
}
});
});

Inserting image to SAP HANA Table using XSJS

I know this is a known issue but I'm having difficulty on fixing my problem. It seems that I don't receive anything from my UI5 Application when I sent an image via FileUploader to my server. I am new to HCP and this is my first time handling XSJS file. I hope you can help me.
UI5.controller.js
sap.ui.define([
"sap/ui/core/mvc/Controller"
], function(Controller) {
"use strict";
return Controller.extend("sample.controller.View1", {
handleUploadPress : function(oEvent)
{
var fileLoader =this.getView().byId("FileLoader");//XML View
var fileName = fileLoader.getValue();
jQuery.sap.require("sap.ui.commons.MessageBox");
if (fileName === "" )
{
sap.ui.commons.MessageBox.show("Please choose File.", sap.ui.commons.MessageBox.Icon.INFORMATION, "Information");
}
else
{
var uploadUrl = "https://xxxxxx/services/Sample.xsjs?file_name="+fileName;
var formEle = jQuery.sap.domById("UpdateContact--FileLoader");
var form = $(formEle).find("form")[0] ;
var fd = new FormData(form);
$.ajax({
url: uploadUrl,
type: "GET",
beforeSend: function(xhr)
{
xhr.setRequestHeader("X-CSRF-Token", "Fetch");
},
success: function(data, textStatus, XMLHttpRequest) {
var token = XMLHttpRequest.getResponseHeader('X-CSRF-Token');
$.ajax({
url: uploadUrl,
type: "POST",
processData :false ,
contentType: false,
data: fd,
beforeSend: function(xhr)
{
xhr.setRequestHeader("X-CSRF-Token", token);
},
success: function(data, textStatus, XMLHttpRequest)
{
var resptext = XMLHttpRequest.responseText;
jQuery.sap.require("sap.ui.commons.MessageBox");
sap.ui.commons.MessageBox.show(resptext, sap.ui.commons.MessageBox.Icon.INFORMATION, "Information");
if(data === "Upload successful"){
sap.ui.commons.MessageBox.show("File uploaded.", sap.ui.commons.MessageBox.Icon.INFORMATION, "Information");
}
},
error: function(data, textStatus, XMLHttpRequest)
{
sap.ui.commons.MessageBox.show("File could not be uploaded.", sap.ui.commons.MessageBox.Icon.ERROR, "Error");
}
});
}} ) ;
}
}
});
XSJS Service:
$.response.contentType = "text/html";
try
{
var conn = $.hdb.getConnection();
var filename = $.request.parameters.get("file_name");
var headers = $.entity.headers.length;
var pstmt = conn.prepareStatement("INSERT INTO \"XXX_ASSETS\".\"XXX\" VALUES('1',?,'test',CURRENT_USER,CURRENT_TIMESTAMP)");
if($.request.entities.length > 0){
var file_body = $.request.entities[0].body.asArrayBuffer();
pstmt.setBlob(1,file_body);
pstmt.execute();
$.response.setBody("[200]:Upload successful!");
}
else
{
$.response.setBody("No Entries");
}
pstmt.close();
conn.commit();
conn.close();
}
catch(err)
{
if (pstmt !== null)
{
pstmt.close();
}
if (conn !== null)
{
conn.close();
}
$.response.setBody(err.message);
}
}
My code was built based on the tutorials I have found on the internet. Thank You.
A good way to save the image is converting(Base64) and save as blob in HANA table.

my function is:
function fetchOwners(existingOwnersObj)
{
//alert("in fetch owners");
var inputVal = JSON.stringify(existingOwnersObj);
//alert("inputVal===> "+inputVal);
var hash1 = cal_hmac(inputVal);
var m = "";
document.getElementById('imgdiv')
.style.display = 'block';
$
.ajax(
{

var str1 = JSON.parse(str);
//new Pouch('idb://tamilNilamExist', function(err, db)
Pouch(puch, function(err, db)

//alert("Data Locally Stored Successfully adkkdd exizthhh");
$("#imgdiv")
.hide();
}
});
});
// getexist();
//
},
error: function(jqXHR, exception)
{
// alert("Error:"+JSON.stringify(jqXHR));
alert("Error Occured");
document.getElementById('imgdiv')
.style.display = 'none';
}
});
}
It looks like you are using a very old version of PouchDB. If you update to 3.4.0, you should be able to easily do something like:
// only need to instantiate the PouchDB once
var db = new PouchDB('mydb');
// inside of asynchronous functions, just call the db directly
function asyncSomething() {
function asyncSomethingElse() {
db.put(...)
}
}

How get json parameters if I use post method in vertx?

I want to get all post parameters.
This is my vertx code:
var vertx = require('vertx/http');
var console = require('vertx/console');
var Server= vertx.createHttpServer();
Server.requestHandler(function(req) {
console.log(req.path());
console.log(req.method());
console.log(req.params());
// nothing
if(myPostparametersContainAnyitem){ //do anything}
else{
var file = req.path() === '/' ? 'index.html' : req.path();
req.response.sendFile('html/' + file);}
}).listen(8081)
This is my button click code:
$.ajax({
data: {name:'foo',age:'13'},
url: '/somedir',
type: 'post',
dataType: 'json',
success: function (response) {
alert(response);
}
});
I discovered how to do it thanks
var vertx = require('vertx');
var console = require('vertx/console');
var Server = vertx.createHttpServer();
Server.requestHandler(function (req) {
var file = req.path() === '/' ? 'index.html' : req.path();
if (file === '/foo') {
foo(req);
}
else{
req.response.sendFile('html/' + file);
}
}).listen(8081);
function foo(req) {
console.log(req);
req.bodyHandler(function (data) {
//data is json {name:foo, age:13}
//do
req.response.end(data);
});
}
