I am attempting to retrieve a file from the server using REST in JAVA and pass some parameters. Although I have had success with the FileSaver.js library, it is not functioning properly in Safari 8. How can I go about downloading the file in Safari? I have come across solutions like angular http get, but that seems limited to Google Chrome and does not allow passing parameters to the HTTP GET request. My backend is implemented in JAVA with Spring MVC.
Handling file serving on the backend:
@RequestMapping(value = "/fileService/temp/{temporalLink}", method = RequestMethod.GET)
public ResponseEntity<byte[]> getFileByTemporalLink(@PathVariable @NotNull String temporalLink) {
byte[] fileContent; // obtain file content
String fileName; // determine file name
String mediaType; // identify media type
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.parseMediaType(mediaType));
headers.setContentDispositionFormData("attachment", fileName);
return new ResponseEntity<>(fileContent, headers, HttpStatus.OK);
}
Requesting the file on the front-end:
Within the controller:
$scope.exportProductToPdf = function (someParams) {
getFileDownloadLink(someParams).then(function (response) {
$window.location.href = '/fileService/temp/' + response;
});
};
// somewhere in the code
var getFileDownloadLink = function(someParams) {
//perform promise work to find the requested file
// ultimately resolve the filename
return $q(function(resolve, reject) {
//work...
resolve("filename.png");
});
}
