Swift网络框架Alamofire图片或者文件上传

有时候会用到图片上传或者文件上传，做法是转成Data

swift3.0 Alamofire4.4情况下，因为每个版本代码会有些偏差

你选择相册或者是拍照之后，返回的image

let imgedata = UIImagePNGRepresentation(image!)

我的做法是先保存到沙盒，第一步要做的是获取沙盒位置

let DocumentsPath = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)[0] as NSString

//文件管理器

let fileManager = FileManager.default

//拷贝至沙盒中 并保存为image.png

try! fileManager.createDirectory(atPath: DocumentsPath as String, withIntermediateDirectories: true, attributes: nil)

fileManager.createFile(atPath: (DocumentsPath as String) + "/image.png", contents: imgedata, attributes: nil)

//获取Home目录

let homeDirectory = NSHomeDirectory()

let documentPath = homeDirectory + "/Documents"

do {

try fileManager.createDirectory(atPath: documentPath, withIntermediateDirectories: true, attributes: nil)

}

catch let error {

}

//得到选择后沙盒中图片的完整路径

let filePath: String = String(format: "%@%@", documentPath, "/image.png")

接下来利用Alamofire，首先得获取到要上传的文件

let lastData = NSData(contentsOfFile: filePath)

然后

let headers = ["content-type":"multipart/form-data"]

Alamofire.upload(multipartFormData: { multipartFormData in

multipartFormData.append(lastData, withName: "image(看你自己)”, fileName: filePath, mimeType: "image/png")

}

},  to: urlString(自己服务器上传的地址),headers: headers,encodingCompletion: { encodingResult in 

switch encodingResult {

case .success(let upload, _, _):

upload.responseJSON { response in

if let value = response.result.value as? [String: AnyObject]{

success(value)

}

}

upload.uploadProgress { progress in

//这个是获取实时进度的，有些需要展示进度，看个人

}

case .failure(let encodingError):

failture(encodingError)

}

}

)
