我正在通過此格式發送請求，以使用參數發出請求。但是，我將如何使用此參數將圖像作爲多部分主體發送？如何使圖像Alamofire放置請求參數？
class APIManager: NSObject {
enum Router: URLRequestConvertible {
static var baseURLString = baseURLString
static let xSource = X_SOURCE_HEADER
case updateProfile([String: AnyObject])
var method: HTTPMethod {
switch self {
case .updateProfile:
return .put
}
}
var path: String {
switch self {
case .updateStockShelfUnits:
return profile_url
}
}
func asURLRequest() throws -> URLRequest {
let url = try GlobalData.gBaseURLString.asURL()
var urlRequest = URLRequest(url: url.appendingPathComponent(path))
urlRequest.httpMethod = method.rawValue
switch self {
case .updateProfile(let parameters):
urlRequest.setValue(access_token, forHTTPHeaderField: "X-User-Token")
urlRequest = try URLEncoding.default.encode(urlRequest, with: parameters)
}
return urlRequest
}
}
func makeRequestToUpdateProfile(param: [String : AnyObject], img: UIImage, completion: @escaping completionHandlerWithSuccessAndErrorMessage) {
Alamofire.request(Router.updateprofile(param)) .responseJSON { response in
switch response.result {
case .success(let JSON):
print(JSON)
completion(true, "Success")
case .failure(let Error):
print("Request failed with error: \(Error)")
completion(false, Error.localizedDescription)
}
}
}
}
在這裏，我會做什麼，使圖像作爲多部分身體請求參數？請求只有參數運行良好的API。
通過 斯威夫特3和 Alamofire 4// import Alamofire
func uploadWithAlamofire() {
let image = UIImage(named: "bodrum")!
// define parameters
let parameters = [
"hometown": "yalikavak",
"living": "istanbul"
]
Alamofire.upload(multipartFormData: { multipartFormData in
if let imageData = UIImageJPEGRepresentation(image, 1) {
multipartFormData.append(imageData, withName: "file", fileName: "file.png", mimeType: "image/png")
}
for (key, value) in parameters {
multipartFormData.append((value?.data(using: .utf8))!, withName: key)
}}, to: "upload_url", method: .post, headers: ["Authorization": "auth_token"],
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.response { [weak self] response in
guard let strongSelf = self else {
return
}
debugPrint(response)
}
case .failure(let encodingError):
print("error:\(encodingError)")
}
})
}
