Cross-Origin Request Blocked - .net Web API and JS AJAX - c#

I'm attempting to use Ajax to capture a submit event and then send the form elements formatted as JSON to a asp.net Web API 2. I am using the latest version of FireFox. Ad blocker is disabled. I have an SSL on both origin and destination. I have followed the steps in this guide to Enable cross-origin requests.
https://learn.microsoft.com/en-us/aspnet/web-api/overview/security/enabling-cross-origin-requests-in-web-api
I have tested that my form with out javascript can send to the API no problem and recieve results.
I have also tested using Postman.
I would like to capture the response from the API and show it in an alert message.
here is a screen shot of the error in the browser

here is a screen shot from postman of the server response confirming it accepts all

Here is my API Controller Info
`
[EnableCors(origins: "*", headers: "*", methods: "*", exposedHeaders: "*", SupportsCredentials = false)]
public class UsersController : ApiController
{
//user login
[Route("api/Users/Login")]
[HttpPost]
public UsersSession Login(Users users)
{
UsersSession UsersSession = new UsersSession();
UsersSession.result = new Result();
try
{
if (users != null && !string.IsNullOrWhiteSpace(users.username) && !string.IsNullOrWhiteSpace(users.password))
{
var v_meta_list = new List<string>();
var v_search_results = new List<string>();
v_meta_list.Add("username=" + users.username);
v_meta_list.Add("password=" + users.password);
v_search_results = CL_db.db_search("4", v_meta_list, true);
if (v_search_results != null && v_search_results.Count > 0)
{
UsersSession.userid = v_search_results[0];
UsersSession.result.result = true;
UsersSession.result.message = "success";
}
else
{
UsersSession.result.result = false;
UsersSession.result.message = "Invalid user";
}
}
else
{
UsersSession.result.result = false;
UsersSession.result.message = "Please enter username and password";
}
}
catch (Exception ex)
{
UsersSession.result.result = false;
UsersSession.result.message = "Error occurred: " + ex.Message.ToString();
}
return UsersSession;
}
}
Here is the web.config
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Headers" value="*" />
<add name="Access-Control-Allow-Methods" value="*" />
</customHeaders>
</httpProtocol>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="OPTIONSVerbHandler" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
`

So the issue was that I had the cors stuff defined in too many locations.
The solution was simply to only have the code for the WebApiConfig.cs
I removed the code from the web.config and the controller.

Google reCAPTACHA - hosted in IIS - Server responded with a status of 503 (Service Unavailable) - MVC5

I integrate Google reCAPTCHA in my Registration page using MVC - Ajax.
I can able to submit reCAPTACHA in my localhost. But after I deployed into the server - getting Service unavailable 503 error. I have a different key for localhost and demo.com
No changes in my code after deployed. I just updated my Google reCAPTACHA Key from config. When Form Submit action getting service unavailable error.
Here is my Google reCaptacha Key
Here is my index.cshtml page code
<form id="reg-form" class="col-sm-6 col-sm-offset-3" action="#Url.Action("Submit","Registration")" method="post" novalidate>
<div class="form-group">
<label class="control-label" for="reg-name">Enter your name:</label>
<div class="regs">
<input id="FullName" name="FullName" class="form-control" type="text" data-error-empty="Please enter your name">
<i class="fa fa-user"></i>
</div>
</div><!-- End Name input -->
<div class="form-group">
<div id='recaptcha' class="g-recaptcha" data-error-empty="The captcha field is required."
data-sitekey="publicKeyfromGooglereCAPTACHA"></div>
</div>
<p>
<button name="submit" type="submit" class="btn btn-qubico btn-block g-recaptcha"
data-error-message="Fill out all information above!" data-sending-message="Sending..." data-ok-message="Message Sent"
data-callback="onSubmit">
<i class=" fa fa-location-arrow">
</i>Submit
</button>
</p> </form>
Here is my Registration.cs Controller
[HttpPost]
[System.Web.Services.WebMethod]
public JsonResult Submit(FormCollection formcollection)
{
try
{
int status = 0;
form.FullName = formcollection["FullName"];
CaptchaResponse response = ValidateCaptcha(Request["g-recaptcha-response"]);
if (response.Success)
{
status = 1;
}
else
{
status = 0;
}
return Json(status);
}
catch (Exception ex)
{
return Json(ex.Message + ex.InnerException.Message);
}
}
[HttpPost]
/// <summary>
/// Validate Captcha
/// </summary>
/// <param name="response"></param>
/// <returns></returns>
public static CaptchaResponse ValidateCaptcha(string response)
{
string secret = System.Web.Configuration.WebConfigurationManager.AppSettings["recaptchaPrivateKey"];
var client = new WebClient();
var jsonResult = client.DownloadString(string.Format("https://www.google.com/recaptcha/api/siteverify?secret={0}&response={1}", secret, response));
return JsonConvert.DeserializeObject<CaptchaResponse>(jsonResult.ToString());
}
Here is my Model CaptchaResponse.cs -
public class CaptchaResponse
{
[JsonProperty("success")]
public bool Success
{
get;
set;
}
[JsonProperty("error-codes")]
public List<string> ErrorMessage
{
get;
set;
}
}
Here is my Jquery script
$(document).ready(function () {
$('#reg-form').submit(function () {
$.ajax({
type: "POST",
url: "Registration/Submit",
data: formInput,
dataType: "json",
success: function (data) {
console.log(JSON.stringify(data));
},
error: function (data) {
console.log(JSON.stringify(data));
}
});
}
return false;
});
});
Here is my web.config code
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
<add key="reCaptchaPublicKey" value="publicKeyfromGooglereCAPTACHA" />
<add key="reCaptchaPrivateKey" value="privateKeyfromGooglereCAPTACHA" />
Note: Application hosted in https port.
Let me know if any more details required.
This issue is fixed. I have added below lines in the config file.
<handlers>
<add name="MSCaptcha" verb="GET" path="/CaptchaImage.axd" type="MSCaptcha.captchaImageHandler, MSCaptcha"/>
</handlers>
or use the below steps to add handlers
Select your application in IIS.
Open Handler Mappings under IIS either by double click the Handler Mappings
or click "open feature" under Action
Click "Add Managed Handler" under action.
Enter "CaptchaImage.axd" without quotes in Request Path Under Type select
MSCaptcha.CaptchaImageHandler
Enter "MSCaptcha" without quotes in Name and click OK

Hosting a webService in Sharepoint

I'm loosing my mind with an issue about hosting wcf in SharePoint. I'm not able to reach my webservice, I saw on it on my SharePoint site but when I'm clicking on it I have an error message
Edit: I delete my public key to be sure that the problem doensn't come from here
So i have my ASP.NET Web Application which is called: Foo.PS2016.PSIExtension
With its iservice and Service (Very simple one):
Iservice:
namespace Foo.PS2016.PSIExtension
{
[ServiceContract]
interface IService
{
[OperationContract]
bool isAlive();
}
}
Service:
namespace Foo.PS2016.PSIExtension
{
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
internal class Service : IService
{
public bool isAlive()
{
return (true);
}
}
}
its Service.svc:
<%# ServiceHost Language="C#" Debug="true" Service="Foo.PS2016.PSIExtension.Service" %>
and its webservice:

The Version, culture and PublicKey comes from a powershell command from the file: Foo.PS2016.PSIExtension.dll

Change your .svc file to:
<%# ServiceHost Language="C#" Debug="true"
Service="Foo.PS2016.PSIExtension.Service, $SharePoint.Project.AssemblyFullName$"
CodeBehind="Service.cs"
Factory="Microsoft.SharePoint.Client.Services.MultipleBaseAddressWebServiceHostFactory, Microsoft.SharePoint.Client.ServerRuntime, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
MultipleBaseAddressWebServiceHostFactory creates configuration dynamically so you can get rid of your web.config modifications and you will have your REST endpoint working out-of-the-box after deployment.
and decorate your interface methods with WebGet attribute:
[WebGet(UriTemplate = "isAlive", BodyStyle = WebMessageBodyStyle.Bare)]
and additionally (not necessarily) add BasicHttpBindingServiceMetadataExchangeEndpointAttribute to your class
As I said in comments, this tutorial goes through all actions step by step so use it!

404 error in calling ashx handler of Web Api

I have an ImageUploadHandler.ashx handler in my WebApi Project. Source code is available here. I am trying to call my handler from my AngularJs project. Here is the code:
var serviceBase = 'http://baseDomain/';
var plupload = null;
$scope.uploadedFiles = [];
$scope.fileUpload = {
url: serviceBase + 'ImageUploadHandler.ashx',
options: {
multi_selection: true,
drop_element: "pluploadDropzone",
chunk_size: '200kb',
runtimes: 'html5,flash,silverlight,html4',
browse_button: "pluploadDropzone",
container: "pluploadContainer",
max_file_size: '3mb',
mime_types: [{ title: 'Allowed', extensions: 'jpeg, jpg, png, gif' }]
},
callbacks:
{
filesAdded: function (uploader, files) {
plupload = uploader;
for (var i = 0 ; i < files.length ; i++) {
var file = files[i];
$scope.uploadedFiles.push(file);
plupload.start();
}
}
}
}
Html:
<div id="pluploadContainer" class="uploader">
<a ng-hide="uploadedFiles.length >= 10" id="pluploadDropzone"
plupload="fileUpload.url"
plupload-options="fileUpload.options"
plupload-callbacks="fileUpload.callbacks"
class="dropzone html5Dropzone" style="width: 464px;">
<span ng-hide="uploadedFiles.length >= 10" class="instructions html5Instructions">
Drag & Drop Your Files Here!
</span>
</a>
<div class="m-images">
<ul class="images">
<li ng-repeat="file in uploadedFiles" class="image">
<div class="thumbnail">
{{ file.name }}
</div>
<a ng-click="deleteImage(file)" class="delete">×</a>
</li>
</ul>
</div>
I am getting 404 error while calling this handler, Here is the error snapshot:
This did the trick:
public void ProcessRequest(HttpContext context)
{
context.Response.ClearHeaders();
string origin = context.Request.Headers["Origin"];
context.Response.AppendHeader("Access-Control-Allow-Origin",
string.IsNullOrEmpty(origin) ? "*" : origin);
string requestHeaders = context.Request.Headers["Access-Control-Request-Headers"];
context.Response.AppendHeader("Access-Control-Allow-Headers",
string.IsNullOrEmpty(requestHeaders) ? "*" : requestHeaders);
context.Response.AppendHeader("Access-Control-Allow-Methods", "POST, OPTIONS");
}
Plus I have to register my handler in web.config
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
<modules runAllManagedModulesForAllRequests="true">
</modules>
<handlers>
<add name="ImageUploadHandler" verb="*" path="ImageUploadHandler.ashx" type="JetAdz.WebApi.ImageUploadHandler, JetAdz.WebApi, Version=1.0.0.0, Culture=neutral" />
</handlers>
</system.webServer>

WEB API MVC4 - using datagrid to post

I have successfully written a MVC4 webapi that takes CompanyID, name and posts it to DB. I need to change it in such a way that the user can enter multiple values for CompanyID with their Names and Save it to DB in one shot. How can I do that? Here's my code
--Index.cshtml
<div id="body">
<section class="featured">
<div class="content-wrapper">
<hgroup class="title">
<h1>Welcome Web API!</h1>
</hgroup>
</div>
</section>
<section class="content-wrapper main-content clear-fix">
<p>
For API documentation: #Html.ActionLink("API", "Index", "Help", new { area = "" }, null)
</p>
<p>
Update/Insert Company info: Click Here!
</p>
</section>
</div>
--Companies.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>
<body>
<script>
var overrides = Array();
function parseform(button) {
var CompanyID = $("#CompanyID").val();
var CompanyName = $("#CompanyName").val();
var lst = {
CompanyID: CompanyID,
CompanyName: CompanyName
}
if (button.attr('value') === "POST") {
console.log("posting : " + lst.toString());
postdata(lst);
} else {
console.log("ERROR");
}
}
function postdata(lst) {
$("#response").text("Posted");
$.ajax({
type: "POST",
dataType: "json",
url: "api/Company/",
data: lst,
xhrFields: {
withCredentials: true
},
success: function (data, status, xhr) {
console.log(status);
$("#response").text(status)
},
error: function (xhr, status, error) {
console.log(xhr.responseText);
var json = jQuery.parseJSON(xhr.responseText);
console.log(json);
$("#response").text(status)
alert(json.Message);
}
});
}
$(document).ready(function () {
$('input:button').click(function () {
parseform($(this));
});
});
</script>
<div id="form">
<label for="CompanyID">CompanyID:</label><input type="text" id="CompanyID" /><br />
<label for="CompanyName">CompanyName:</label><input type="text" id="CompanyName" /><br />
<input type="button" id="Post" value="POST"/>
</div>
<div id="response">
</div>
</body>
</html
In CompaniesController, I have written a call to stored procedure for the POST method to save one record at a time.
How can I Post many rows at a time & what changes should I do to html file.
Thanks

How did you declared your variables in your Model. For operating multivalued types, try something like this:
private ICollection<string> _variable;
public ICollection<string> VariableName
{
get
{
if (_variable == null)
{
return new Collection<string> {""};
}
else
{
return _variable;
}
}
set { _variable = value; }
}
