How can i use multipartFormData in Swift / Alamofire? - swift

Question

upload(.POST, isEdit == true ? mainURL+URLS.UpdateLicense.rawValue : mainURL+URLS.AddLicense.rawValue, multipartFormData: {
multipartFormData in
if let imageData = UIImageJPEGRepresentation(self.selectdImage, 1) {
multipartFormData.appendBodyPart(data: imageData, name: "image", fileName: "image.jpeg", mimeType: "image/jpeg")
I want to append body part in the string and I can't find any method by that I can append a string with this body part. It's required only data.But my parameter is a string and I have to pass it as a string not in data.

Answer 1

Try this:
Swift 2.0
multipartFormData.appendBodyPart(data: imageData.dataUsingEncoding(NSUTF8StringEncoding)!, name: "image")
Swift 3.0
multipartFormData.append(imageData(using: String.Encoding.utf8)!, withName: "image")

This is my code in my project. I Hope it can help you
var parameters: [String: String] = [
"Tag" : tagName,
"Title" : title,
"Content" : content,
"TypePost" : "0",
"CreatedAt" : "\(Date())"
]
for (key, value) in parameters {
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
}

You want to upload UIImage with other parameters, so here how you can achieve that!
if let imageData = UIImageJPEGRepresentation(image, 1) {
multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "file.png", mimeType: "image/png")
}
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
}
You need to differentiate both the things UIImage and other String parameters.
Let me know, if you still face problem.
