如何使用带有基本身份validation的alamofire多部分表单数据上传图像？

我是编程和iOS开发的新手。 我需要使用Alamofire多部分表单数据上传图像，但我还需要输入基本身份validation标头。

在这个线程Alamofire 4.0上传MultipartFormData Header ，它似乎与我的问题类似，代码就像这样上传

Alamofire.upload(multipartFormData:{ multipartFormData in multipartFormData.append(unicornImageURL, withName: "unicorn") multipartFormData.append(rainbowImageURL, withName: "rainbow")}, usingThreshold:UInt64.init(), to:"https://httpbin.org/post", method:.post, headers:["Authorization": "auth_token"], encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in debugPrint(response) } case .failure(let encodingError): print(encodingError) } }) 

但我很困惑如何把基本认证（即用户名和密码）标题。 我也很困惑我应该放置我的图像数据。

我找到了另一个与我的问题类似的线程。 这里是… 如何使用Alamofire上传带有身份validation的MultipartFormData ，建议的解决方案是这段代码：

 let username = "username" let password = "password" let credentialData = "\(username):\(password)".dataUsingEncoding(NSUTF8StringEncoding)! let base64Credentials = credentialData.base64EncodedStringWithOptions([]) let headers = ["Authorization": base64Credentials] Alamofire.upload( .POST, "https://rilbits.com/supersafe/photo/upload", headers: headers, multipartFormData: { multipartFormData in let data = "default".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)! multipartFormData.appendBodyPart(data: data, name: "_formname") multipartFormData.appendBodyPart(fileURL: fileURL, name: "photo") }, encodingCompletion: { encodingResult in switch encodingResult { case .Success(let upload, _, _): upload.responseString { response in debugPrint(response) } case .Failure(let encodingError): print(encodingError) } } ) 

但在修复到swift 4.1后，它会出错：

你能帮忙解决我的问题吗？ 提前致谢 ：）

我创建了这个function：希望它适合你： –

  //Alamofire file upload code func requestWith(URLString: String, imageData: Data?, fileName: String?, pathExtension: String?, parameters: [String : Any], onView: UIView?, vc: UIViewController, completion:@escaping (Any?) -> Void, failure: @escaping (Error?) -> Void) { let headers: HTTPHeaders = [ "Content-type": "multipart/form-data" ] let URL = BASE_PATH + URLString Alamofire.upload(multipartFormData: { (multipartFormData) in for (key, value) in parameters { multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: key as String) } if let data = imageData { multipartFormData.append(data, withName: "fileUpload", fileName: "\(fileName!).\(pathExtension!)", mimeType: "\(fileName!)/\(pathExtension!)") } }, usingThreshold: UInt64.init(), to: URL, method: .post, headers: headers) { (result) in switch result { case .success(let upload, _, _): upload.responseJSON { response in if let err = response.error { failure(err) return } completion(response.result.value) } case .failure(let error): print("Error in upload: \(error.localizedDescription)") failure(error) } } }

我终于找到了答案，请使用下面的代码

 func uploadDefect(defectRemark: String, defectLocation: String, defectImage: UIImage, fileNameImage: String, completion: @escaping(_ errorMessage: String?) -> Void) { guard let imgData = defectImage.jpeg(.medium) else {return} let urlUpload = URLService.uploadDefect.endPoint let username = "admin" let password = "1234" let parameters : [String:Any] = ["defect_remark" : defectRemark, "defect_location": defectLocation, "tenant_id" : tenantID] var headers: HTTPHeaders = [:] if let authorizationHeader = Request.authorizationHeader(user: username, password: password) { headers[authorizationHeader.key] = authorizationHeader.value } Alamofire.upload( multipartFormData: { multipartFormData in for (key, value) in parameters { multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: key as String) } multipartFormData.append(imgData, withName: "file", fileName: fileNameImage, mimeType: "image/jpeg") }, to: urlUpload, headers: headers, encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in debugPrint(response) } case .failure(let encodingError): print(encodingError) } } ) }

 Use : Alamofire.upload(multipartFormData:{ multipartFormData in multipartFormData.append(data, withName: "_formname") multipartFormData.append(fileURL, withName: "photo")}, usingThreshold:UInt64.init(), to:"URL", method:.post, headers:["Authorization": "auth_token"], encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in debugPrint(response) } case .failure(let encodingError): print(encodingError) } })
