XHR load local file synchronization

[ghost]

Dear @ALL,
At this moment, when use this plugin, I cannot load local file via XHR synchronization as below:
xhttp.open("GET", filePath, false); xhttp.send(null); var text = xhttp.responseText;
Is this issue?
Thank you so much.

@taxuangiao No such issue exists as reported by you. Plugin works fine for synchronous request as well.

@manish2788 Thanks. However, I retry with synchronous XHR request and It is not OK. But I update to asynchronous XHR request, I could load file content. So please check again.

@taxuangiao Can you please share a sample cordova app demonstrating the issue you are facing.

@manish2788 there are source code to load file
var xhr = new XMLHttpRequest();
xhr.open("GET", "js/test.txt", false);
xhr.send();
var data = xhr.responseText;
if (data) {
alert(data);
} else {
alert("ERROR");
}
the result is show alert "ERROR"

@taxuangiao Please go through https://javascript.info/xmlhttprequest to understand how to create an XMLHttpRequest request and get a response. No issue with the plugin.

@manish2788 , with above code, I tried remove this plugin and build on cordova-ios@4 (UIWebView) and it is OK. I think the plugin not support synchronous XHR request.

On the ios side the http request, response is synchronous but the communication with the plugin is asyc. The client registers a callback handler. At the time this was originally development, Js es6 await/async was not an option. It might be possible now for the send to return a promise and the client could call await xhr.send(). Kind of a JS impl restriction.
