How to receive angular $http post multipart form data from Grails. Here I have sent multipart form data from Angular controller to the Grails. I am new to Grails.
Anyone can give me guidance to retrieve-boundary data. I don't Know exactly it's correct form to receive image file data with some input data also.
Request headers in browser's network console:
Provisional headers are shown

Here you go. Just write the following in your controller:
class MyController {
def upload() {
def multipartFile = params.rackImage
InputStream is
FileOutputStream fos
byte[] fileRead = new byte[1024]
File tempFile
try {
is = multipartFile.getInputStream()
String fileName = multipartFile.getOriginalFilename()
String path = "./"
fileName = fileName.replaceAll("[^a-zA-Z0-9//._-]+", "").toLowerCase()
tempFile = new File(path + "" + fileName)
fos = new FileOutputStream(tempFile);
int i = is.read(fileRead)
while (i != -1) {
fos.write(fileRead, 0, i);
i = is.read(fileRead);
}
} catch (FileNotFoundException e) {
log.error "Exception uploading", e
} catch (IOException e) {
log.error "Exception uploading", e
} finally {
fos?.close()
is?.close()
}
// Now access the File: "tempFile"
}
}
