多部分表单（图像，参数，标题），快速与Alamofire一起发布请求

本文介绍了多部分表单（图像，参数，标题），快速与Alamofire一起发布请求的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

首先，我想说我是新手，并且了解一点。因此，可以寻求任何帮助。我有一个包含数据（配置文件图像），一些参数（名字，姓氏）和标头（用户标识，hashCode）的多部分数据形式。我想发送POST请求以提交表单。

Firstly, i want to say i am new to swift, and know a little.So any help would be appriciated. I have a multipart-data form which has a image (profile-image), a few parameters (first-name, last-name) and headers(userid, hashCode). I want to send a POST request to submit the form.

我能够仅使用标头和其他参数发出POST请求，但图像除外：

I have been able to make POST request with only, headers and other parameters except image as:

let headers = [ "user_id": (Helper.getUserInfo()?.user_id)!, "hash_code":(Helper.getUserInfo()?.hash_code)!, ] let params = [ "name": self.name.text!, "address":self.address.text!] Alamofire.request(.POST, kFormUrl, parameters:params ,headers:headers).responseJSON { [weak self] response in //working fine }

但是如何将图像作为文件发送（不是base-64string），即使用参数和标头。

But how to send image as a file (not base-64string) i.e. direct file upload with parameters and headers.

预先感谢

推荐答案

您可以使用 Alamofire 3.0 + 下面的代码

func uploadImageAndData(){ //parameters let gender = "M" let firstName = "firstName" let lastName = "lastName" let dob = "11-Jan-2000" let aboutme = "aboutme" let token = "token" var parameters = [String:AnyObject]() parameters = ["gender":gender,"firstName":firstName,"dob":dob,"aboutme":aboutme,"token":token,"lastName":lastName] let URL = "yourserviceurl/" let image = UIImage(named: "image.png") Alamofire.upload(.POST, URL, multipartFormData: { multipartFormData in if let imageData = UIImageJPEGRepresentation(image, 0.6) { multipartFormData.appendBodyPart(data: imageData, name: "image", fileName: "file.png", mimeType: "image/png") } for (key, value) in parameters { multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key) } }, encodingCompletion: { encodingResult in switch encodingResult { case .Success(let upload, _, _): print("s") upload.responseJSON { response in print(response.request) // original URL request print(response.response) // URL response print(response.data) // server data print(response.result) // result of response serialization if let JSON = response.result.value { print("JSON: \(JSON)") } } case .Failure(let encodingError): print(encodingError) } }) }
