如何使用参数调用post服务swift 3.0 Alamofire 4.0？
我有参数
var Param : [String:String] = [:] 我在用
Alamofire.upload( multipartFormData: { multipartFormData in
但在响应它说invalid service是他们在参数编码它出错了？
multipartFormData用于在服务器上上传图像。 所以如果你想上传图片数据然后尝试使用下面的代码。
let payload: [String: AnyObject] = [ "key1": "val1" as AnyObject, "key2": true as AnyObject, "key3" : [1,2,3,4] as AnyObject ] let requestString = "http://www.url.com/api/action" Alamofire.upload(multipartFormData: { (multipartFormData) in multipartFormData.append(UIImageJPEGRepresentation(self.photoImageView.image!, 0.5)!, withName: "photo_path", fileName: "swift_file.jpeg", mimeType: "image/jpeg") for (key, value) in payload { multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key) } }, to: requestString, method: .post , headers:nil, encodingCompletion: { (result) in switch result { case .success(let upload, _, _): upload.uploadProgress(closure: { (progress) in print(progress.fractionCompleted * 100) }) upload.responseJSON(completionHandler: { (response) in }) case .failure(let error): print(error) } })
如果你想调用发布请求然后尝试使用下面的代码：
let urlString = "https://httpbin.org/get" Alamofire.request(urlString, method: .post, parameters: ["foo": "bar"],encoding: JSONEncoding.default, headers: nil).responseJSON { response in switch response.result { case .success: print(response) break case .failure(let error): print(error) } }
对于swift 3，请使用下面的代码。 它在我所有的项目中工作得非常好
//Parameters let paramDic : NSMutableDictionary = [ "key1" : "value1", "key2" : "value2", ] let urlString = "www.mywebsite.net/api/" let url : URL = URL.init(string: urlString)! var request = URLRequest(url: url) //Setting HTTP method GET/POST/PUT request.httpMethod = "POST" //Setting header request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type") request.setValue("application/json", forHTTPHeaderField: "Accept") //Setting parameters request.httpBody = try! JSONSerialization.data(withJSONObject: paramDic!, options: []) if paramDic != nil { request.httpBody = try! JSONSerialization.data(withJSONObject: paramDic!, options: []) } alamoFireManager!.request(request as URLRequestConvertible).responseJSON { response in switch response.result { case .failure(let error): print("\(urlString) failure response -> \n NSHTTPURLResponse ->\(response.response) \n \(error)") case .success : print("\(urlString) success response -> \n NSHTTPURLResponse ->\(response.response) \n Data -> \(response.result.value as? NSDictionary)") } }
第一个答案是简单的后期API。 如果要发布多部分数据，请使用以下方法。
/** Call this to create a request with any HTTP method - parameter httpMethodType: HTTP method type post,get etc - parameter headers: HTTP header key-value pair (no need to Content-Type,Accept) - parameter serviceName: name of service which need to call - parameter paramDic: parameters in key-value pair - parameter files: array of NSData objects for file content - parameter success: success callback handler - parameter failure: failure callback handler */ func uploadFileRequestWithParameters(_ paramDic : NSMutableDictionary?, files: NSMutableArray?, headers : NSMutableDictionary?, serviceName : NSString, success: @escaping (( _ response : HTTPURLResponse?, _ data : NSDictionary?) -> Void), failure: @escaping ((_ error : Error? ) -> Void)) { let urlString = BASE_URL + (serviceName as String) let url : URL = URL.init(string: urlString)! var headerDic = [String : String]() headerDic["Content-Type"] = "multipart/form-data" if headers != nil { let allHeaders : NSArray = headers!.allKeys as NSArray for key in allHeaders { headerDic[(key as? String)!] = (headers!.object(forKey: key)! as? String) } } print("Full HTTP URL -> \(urlString)") print("HTTP Request Method -> POST") print("Full HTTP Headers -> \(headerDic)") print("Full HTTP Parameters -> \(paramDic)") print("Files Array -> \(files)") // Begin upload alamoFireManager?.upload(multipartFormData: { (multipartFormData) in // import image to request for (file) in files! { var mimeTypeStr = "" let fileDic : NSDictionary = file as! NSDictionary if (fileDic.object(forKey: "fileType") as? String == "image" ) { mimeTypeStr = "image/png"; } else if (fileDic.object(forKey: "fileType") as? String == "video" ) { mimeTypeStr = "video/mp4"; } else if (fileDic.object(forKey: "fileType") as? String == "gif" ) { mimeTypeStr = "image/gif"; } multipartFormData.append(fileDic.object(forKey: "fileData") as! Data, withName: fileDic.object(forKey: "fileKey") as! String, fileName: fileDic.object(forKey: "fileName") as! String, mimeType: mimeTypeStr) } // import parameters for (key, value) in paramDic! { multipartFormData.append((value as! String).data(using: String.Encoding.utf8)!, withName: key as! String) } }, usingThreshold: SessionManager.multipartFormDataEncodingMemoryThreshold, to: url, method: .post, headers: headerDic as [String : String], encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON(completionHandler: { response in debugPrint(response) print(response.result.value as? NSDictionary) }) case .failure(let error): print(error) } }) }
像这样从你的课堂上面调用方法。
let image : UIImage = #imageLiteral(resourceName: "splash") let imgData : Data = UIImagePNGRepresentation(image)! // let fileArray : NSArray = NSArray.init(objects: imgData) let parameters : NSMutableDictionary = [ "name" : "Krishna", ] //Array to store file data let filesArray : NSMutableArray = [] //fileType = image/video/gif //fileKey = api parameter key to receive file //Dictionary to hold the individual file data let file1 : NSMutableDictionary = [ "fileData" : imgData, "fileName" : "profileImage.png", "fileType" : "image", "fileKey" : "userProfileImg" ] let file2 : NSMutableDictionary = [ "fileData" : imgData, "fileName" : "video.mp4", "fileType" : "video", "fileKey" : "myVideoKey" ] let file3 : NSMutableDictionary = [ "fileData" : imgData, "fileName" : "image.gif", "fileType" : "gif", "fileKey" : "myGIFKey" ] //Adding all file data dictionaries to array filesArray.add(file1) filesArray.add(file2) filesArray.add(file3) let header : NSMutableDictionary = [ "version": "1.0", "os": "iOS", "token" : HEADER_TOKEN ] uploadFileRequestWithParameters(paraDic, files: files , headers: header, serviceName: UPDATE_PROFILE_API as NSString, success: { (response, data) in } , failure: { (error) in })
