向带有ionic的iis服务器的http请求的未知HTTP错误

Question

I've got a problem with my ionic app. I try to get a json object from my iis (asp.NET) server. But the request doesn't even come into my controller. Everytime, i get the same error:

http failure response for (unknown url) 0 unknown error

At first, I thought it was just a cors problem so i fixed it but now, it works with chrome and internet explorer 11 but not with edge and, more important, it doesn't work on device. I don't think the problem is with my typescript code since there is no problem with a Google request... But, just in case, there is my code:

this.http.get('http://localhost:60196', {withCredentials : true}).subscribe(data => {
  this.testData = JSON.stringify(data);
}, err => {
  this.testData = JSON.stringify(err);
});

For the record: my iis server use windows impersonation and my app must run on windows devices (i didn't try my code with android or ios devices).

Thank you very much.

Answer 1

it doesn't work on device

this.http.get('http://localhost:60196', {withCredentials : true}).subscribe(data => {
  this.testData = JSON.stringify(data);
}, err => {
  this.testData = JSON.stringify(err);
});

Get request is rerencing to localhost . Here should be some Api endpoint when testing it on device...
