Answer 1

You can try by adding the headers to your fetch api, as it posts your record to your url.

var dataObj = {}
dataObj.uname = uname,
dataObj.password = password

fetch("http:/example.com", {
  method: 'post',
  headers: {
    'Accept': 'application/json, text/plain, */*',  // It can be used to overcome cors errors
    'Content-Type': 'application/json'
  },
  body: JSON.stringify(dataObj)
})
.then((response) => response.json())
.then((responseData) => {
  AlertIOS.alert(
      "POST Response",
      "Response Body -> " + JSON.stringify(responseData.body)
  )
}).done();
    this.props.navigation.navigate("Home")
};
