I have been trying to create an android app using nativescript.I am using fetch module to get response from my server.When I am trying to get response from httpbin.org/get ,it is OK.But when I am trying to get response from my local server,I am getting Network Request Failed. error.
Sending to httpbin.org/get-
return fetchModule.fetch("https://httpbin.org/get").then(response => { return response.text(); }).then(function (r) {
console.log(r);
}, function (e) {
console.log(e);
});
Sending to localhost:8000/api-
return fetchModule.fetch("http://localhost:8000/api").then(response => { return response.text(); }).then(function (r) {
console.log(r);
}, function (e) {
console.log(e);
});
When I try to get response from localhost:8000/api in pure node.js via the request module.It worked fine.But now,I don't to know how to solve this in nativescript using fetch module.
Instead, localhost (usually 127.0.0.1) use 10.0.2.2 (if using AVD emulator)
10.0.2.2 - Special alias to your host loopback interface
(i.e., 127.0.0.1 on your development machine)
For GenyMotion emulator the loopback address is 10.0.3.2
