URLRequest with multipart support · GitHub

↑ このサイトの URLRequest+Multipart.swift を使う。

ViewController.swift

override func viewDidLoad() {
super.viewDidLoad()
let url = NSURL(string: "https://【ドメイン】/upload.php")!
let imageJpgData = image.jpegData(compressionQuality: 1.0)!
let imagePngData = image.pngData()!
let request = URLRequest(multipartFormData: { (formData) in
//1. Example with URL to local file
//    try? formData.append(fileUrl: URL(string: "path to file")!, name: "parameterKey")
//2. Example with Data of a file
formData.append(file: imageJpgData, name: "upload_img_jpg", fileName: "test01.jpg", mimeType: "image/jpeg")
formData.append(file: imagePngData, name: "upload_img_png", fileName: "test01.png", mimeType: "image/png")
//3. Example of key/value pair
formData.append(value: "upload_txt_test", name: "upload_txt")
},
url: url as URL,
method: .post,
headers: [:])
let task = URLSession.shared.dataTask(with: request) {
data, response, error in
if error != nil {
print("error=\(String(describing: error))")
return
}
task.resume()
}
