The HyperText Transfer Protocol (HTTP) 405 Method Not Allowed response status code indicates that the request method is known by the server but is not supported by the target resource.,The server must generate an Allow header field in a 405 response containing a list of the target resource's currently supported methods.,Reason: Credential is not supported if the CORS header ‘Access-Control-Allow-Origin’ is ‘*’,Reason: Did not find method in CORS header ‘Access-Control-Allow-Methods’

response with status 0 for url null,may be a server problem. Since 405 means “method not allowed”, you should double-check with Postman or ARC or similar, that your API endpoint at http://10.0.0.0/MovilAppWS/api/Pedidos/Post really answers to the HTTP POST method.,I am trying to solve the following inconvenience that occurs when sending data to the server from a device the error is XMLHttpRequest can not load http://10.0.0.0/MovilAppWS/api/Pedidos/Post. Response for preflight has invalid HTTP status code 405,with postman validate that the information is registered correctly,

var headers = new Headers ({
‘Content-Type’: ‘application / json’,
‘Access-Control-Allow-Origin’: ‘*’,
‘Access-Control-Allow-Headers’: ‘X-API-KEY, Origin, X-Requested-With, Content-Type, Accept, Access-Control-Request-Method’,
‘Access-Control-Allow-Methods’: ‘GET, POST, OPTIONS, PUT, DELETE’
});

 // headers.append ('Content-Type', 'application / json', 'Access-Control-Allow-Origin');
 const requestOptions = new RequestOptions({
    headers: headers
 })
 let url = "http://10.0.0.0/MovilAppWS/api/Pedidos/Post"
 this.http.post(url, this.postData, requestOptions)
    .map(res => res.json()).subscribe(data => {
          const toast = this.toastCtrl.create({
             message: 'Your request has been processed, we will contact you shortly.',
             duration: 5000
             position: 'top'
          });
          toast.present();
       },
       err => {
          const toast = this.toastCtrl.create({
             message: err,
             duration: 5000
             position: 'middle'
          });
          toast.present();
       });

Hey! I’ve been trying to request my API, but I keep getting HTTP error 0. Upon looking in the logs, it give me the following: Failed to load https://ua71u3gk76.execute-api.us-east-1.amazonaws.com/prod/buslineapi: Response for preflight has invalid HTTP status code 400,This is usually for one of two reasons:,Yep, that’s right! HttpError code 0 happens when you make a request from the browser (ie from Form code), and the browser disallows the request.,Please see my code below: url = "https://ua71u3gk76.execute-api.us-east-1.amazonaws.com/prod/buslineapi" body = {"stop_area": "stop_area:WHT:SA:CTP102462", "line": "route:WHT:32-Whistler"} r = anvil.http.request(url,method="POST",json=True,data=body)

and this one is next error XMLHttpRequest cannot load http://aflaree.com/qrcodeservice/Service1.svc/login Response for preflight has invalid HTTP status code 405 after reading some blog i figure there is a CORS extention from from which allows ajax request i tried that also but i am not able to find why this two error is appearing. here is my code,Often Cordova plugins aren't ready when you try to call them, using the promise interface you can avoid getting undefined errors.,The thing is that there were some major changes in Cordova 4.0.0:,The first request (the one with the OPTIONS method) is called pre-flight and is used to check if it's safe to send the full request to the server. The response from the server should contain a valid Access-Control-Allow-Origin header containing the URL of the client or *.

I am using ionic framework and angularjs I use chrome for viewing my logs but here i am doing a login page I am trying to post the user entered data to serve but i am getting this error like .

 OPTIONS http: //aflaree.com/qrcodeservice/Service1.svc/login
