avoir du mal à comprendre le codage des paramètres dans Alamofire 4. Avant d'utiliser l'énumération ParameterEncoding
et de faire quelque chose comme ceci:
Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0
Cependant, cela a depuis été remplacé par le ParameterEncoding
protocol
:
public typealias Parameters = [String: Any]
public protocol ParameterEncoding {
func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest
}
Comment pourrais-je l'intégrer dans mon code actuel? Comment encoder mon mutableURLRequest
actuel?
ÉDITER:
static func urlRequestWithComponents(urlString:String, parameters:Dictionary<String, Any>, data:Data?, contentType: ContentType, parameterName: String) -> (URLRequestConvertible, Data) {
var urlRequest = URLRequest(url: URL(string: urlString)!)
urlRequest.cachePolicy = .reloadIgnoringLocalCacheData
urlRequest.httpMethod = Alamofire.HTTPMethod.post.rawValue
let boundaryConstant = "multipart-boundary";
let multipartContentType = "multipart/form-data;boundary="+boundaryConstant
urlRequest.setValue(multipartContentType, forHTTPHeaderField: "Content-Type")
// Create upload data to send
var uploadData = Data()
if data != nil {
// Add multipart data
uploadData.append("\r\n--\(boundaryConstant)\r\n".data(using: String.Encoding.utf8)!)
if contentType == .Image_JPEG {
uploadData.append("Content-Disposition: form-data; name=\"\(parameterName)\"; filename=\"file.jpeg\"\r\n".data(using: String.Encoding.utf8)!)
uploadData.append("Content-Type: image/jpeg\r\n\r\n".data(using: String.Encoding.utf8)!)
} else if contentType == .Audio {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MMyyyyddsshhmmA" // superset of OP's format
let audioFileName = "recording-\(dateFormatter.string(from: Date())).mp4"
uploadData.append("Content-Disposition: form-data; name=\"\(parameterName)\"; filename=\"\(audioFileName)\"\r\n".data(using: String.Encoding.utf8)!)
uploadData.append("Content-Type: audio/mpeg\r\n\r\n".data(using: String.Encoding.utf8)!)
}
uploadData.append(data!)
}
// Add parameters
for (key, value) in parameters {
uploadData.append("\r\n--\(boundaryConstant)\r\n".data(using: String.Encoding.utf8)!)
uploadData.append("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".data(using: String.Encoding.utf8)!)
}
uploadData.append("\r\n--\(boundaryConstant)--\r\n".data(using: String.Encoding.utf8)!)
// return URLRequestConvertible and Data
return (urlRequest, uploadData)
}
Lors d'une demande:
let urlRequest = urlRequestWithComponents(urlString: url, parameters: parameters, data: imageData, contentType: .Image_JPEG, parameterName: "question_img")
alamoManager.upload(urlRequest.1, with: urlRequest.0).responseObject { (response: DataResponse<CustomResponse>) in
//Some code
}
Vous pouvez faire une simple requête Alamofire
comme celle-ci.
import Alamofire
import AlamofireObjectMapper
import ObjectMapper
//
//
Alamofire.request("hello.com", method: .post, parameters: ["name": "alvin"], encoding: JSONEncoding.default, headers: nil).responseObject(completionHandler: { (response : DataResponse<YourModelHere>) in
})
Vous pouvez voir que j'ai utilisé JSONEncoding
dans cette demande. Vous pouvez choisir votre mode d'encodage là-dedans parmi ceux-ci.
Dans JSONEncoding
default
Alamofire.request("https://httpbin.org/post", method: .post, parameters: parameters, encoding: JSONEncoding.default)
prettyPrinted
Alamofire.request("https://httpbin.org/post", method: .post, parameters: parameters, encoding: JSONEncoding. prettyPrinted)
Et dans URLEncoding
défaut --
Alamofire.request("https://httpbin.org/get", parameters: parameters, encoding: URLEncoding.default)
methodDependent
Alamofire.request("https://httpbin.org/get", parameters: parameters, encoding: URLEncoding(destination: .methodDependent))
chaîne de requête
httpBody
Alamofire.request("https://httpbin.org/post", parameters: parameters, encoding: URLEncoding.httpBody)
Et créez votre propre Custom Encoding
Comme ceci.
public struct MyCusomEncoding: ParameterEncoding {
public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
var urlRequest = try urlRequest.asURLRequest()
guard let parameters = parameters else { return urlRequest }
do {
let data = //
// Do your custom stuff here, convert your parameters it into JSON, String, Something else or may be encrypted...
urlRequest.httpBody = data
} catch {
throw AFError.parameterEncodingFailed(reason: .jsonEncodingFailed(error: error))
}
return urlRequest
}
}
Et vous pouvez utiliser MyCusomEncoding
dans vos Alamofire
requêtes.
Utilisez Alamofire.URLEncoding ()
Exemple de code:
// finalRequest: URLRequest? = nul
do {
try finalRequest = Alamofire.URLEncoding().encode(urlRequest as! URLRequestConvertible, with: parameters)
} catch {
//Handle error
}
return finalRequest!
do {
let alamofireRequest = try Alamofire.URLEncoding().encode(urlRequest as URLRequestConvertible, with: parameters)
Alamofire.request(alamofireRequest).response { (dataResponse) in
}
} catch {
}
