Is it at all possible to download a file upon an ajax request? Does it matter if it's same domain / cross domain?
I know it can be done upon redirecting the browser to a URL and setting relevant headers, but was wondering if it can be done when doing an ajax request.
I'm POSTing JSON as the Request Payload to a URL and based on the content of the JSON, I want to send back a specific file.
client.post(url, body: request, headers:{"Content-Type":"application/json"}).then((res) {
if (res.statusCode == 200) {
if ("application/json" == res.headers["content-type"]) {
// parse JSON here
} else {
// download the content if Content-Disposition is set
}
}
}).whenComplete(() {
client.close();
}).catchError((exception, stacktrace) {
print(exception);
print(stacktrace);
showErrorMessage("An Error Occurred");
});
I can see the the correct headers coming back for downloading a PDF, but it's not doing anything if I receive these headers via an AJAX response.
Update - clarifying:
If you click this link, it will do a GET request to Github and download the file: https://github.com/dartsim/dart/archive/master.zip I'm trying to download the file using a POST request via Dart's BrowserClient.post.
