Swift

最近项目使用Swift进行开发，而Alamofire作为受欢迎的网络请求库，用之无可非议。其实这个上传，用了好久了，今天记录下来吧。批量上传代码如下：

/// 图片上传    ///    /// - Parameters:    ///   - urlString: 服务器地址    ///   - params: 参数 ["token": "89757", "userid": "nb74110"]    ///   - images: image数组    ///   - success: 成功闭包    ///   - failture: 失败闭包    func upload(urlString : String, params:[String:String]?, images: [UIImage], success: @escaping (_ response : Any?) -> (), failture : @escaping (_ error : Error)->()) {        Alamofire.upload(multipartFormData: { multipartFormData in            if params != nil {                for (key, value) in params! {                    //参数的上传                    multipartFormData.append((value.data(using: String.Encoding.utf8)!), withName: key)                }            }            for (index, value) in images.enumerated() {                let imageData = UIImageJPEGRepresentation(value, 1.0)                let formatter = DateFormatter()                formatter.dateFormat = "yyyyMMddHHmmss"                let str = formatter.string(from: Date())                let fileName = str+"\(index)"+".jpg"                                // 以文件流格式上传                // 批量上传与单张上传，后台语言为java或.net等                multipartFormData.append(imageData!, withName: "fileupload", fileName: fileName, mimeType: "image/jpeg")                // 单张上传，后台语言为PHP                multipartFormData.append(imageData!, withName: "fileupload", fileName: fileName, mimeType: "image/jpeg")                // 批量上传，后台语言为PHP。 注意：此处服务器需要知道，前台传入的是一个图片数组                multipartFormData.append(imageData!, withName: "fileupload[\(index)]", fileName: fileName, mimeType: "image/jpeg")            }        },                         to: urlString,                         headers: nil,                         encodingCompletion: { encodingResult in                            switch encodingResult {                            case .success(let upload, _, _):                                upload.responseJSON { response in                                    print("response = \(response)")                                    let result = response.result                                    if result.isSuccess {                                        success(response.value)                                    }                                }                            case .failure(let encodingError):                                failture(encodingError)                            }        }        )    }
