Alamofire 5上传encodingCompletion
Alamofire 5上传encodingCompletion
提问于 2019-03-04 22:12:24
我正在使用Swift 4和Alamofire 5，我上传了两张multibart照片，我想打印进度
AF.upload(
multipartFormData: { MultipartFormData in
MultipartFormData.append(firstPic, withName: "first_pic", fileName: "image.jpeg", mimeType: "image/jpeg")
MultipartFormData.append(secondPic, withName: "second_pic", fileName: "image.jpeg", mimeType: "image/jpeg")
}, to: urlString, encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.progress { bytesRead, totalBytesRead, totalBytesExpectedToRead in
print(totalBytesRead)
}
upload.responseJSON { request, response, result in
print(result)
}
case .Failure(let encodingError):
print(encodingError)
}
})这会得到一个错误，说
参数标签'(multipartFormData:，to:，encodingCompletion:)‘与任何可用的重载都不匹配
是库更新了代码还是什么？？

Alamofire 5不再需要encodingCompletion！相反，多部分表单编码是作为标准的now异步请求流程的一部分完成的，它将在Request上返回错误，并且可以在validate和response*调用期间使用这些错误。

请根据您的需要修改
func upload(image: Data, to url: Alamofire.URLRequestConvertible, params: [String: Any]) {
AF.upload(multipartFormData: { multiPart in
for (key, value) in params {
if let temp = value as? String {
multiPart.append(temp.data(using: .utf8)!, withName: key)
}
if let temp = value as? Int {
multiPart.append("\(temp)".data(using: .utf8)!, withName: key)
}
if let temp = value as? NSArray {
temp.forEach({ element in
let keyObj = key + "[]"
if let string = element as? String {
multiPart.append(string.data(using: .utf8)!, withName: keyObj)
} else
if let num = element as? Int {
let value = "\(num)"
multiPart.append(value.data(using: .utf8)!, withName: keyObj)
}
})
}
}
multiPart.append(image, withName: "file", fileName: "file.png", mimeType: "image/png")
}, with: url)
.uploadProgress(queue: .main, closure: { progress in
//Current upload progress of file
print("Upload Progress: \(progress.fractionCompleted)")
})
.responseJSON(completionHandler: { response in
//Do what ever you want to do with response
if let error = response.error {
print(error)
}
guard let data = response.value else {
return
}
print(value)
})

let headers: HTTPHeaders = [
