Question

几个星期前，我花了一些时间来弄清楚，但我能够使用Akamai的iOS版Netstorage（Swift 2.0）上传文件。

这是我的代码。希望它可以帮助别人。

let kAKAMAI_CONFIGURATION_NETSTORAGE_USER_NAME              = "netstorage_user_name"
let kAKAMAI_CONFIGURATION_NETSTORAGE_KEY                    = "---- YOU NETSTORAGE KEY ---"
let kAKAMAI_CONFIGURATION_NETSTORAGE_HOSTNAME               = "xxxxxx.akamaihd.net"
let kAKAMAI_CONFIGURATION_NETSTORAGE_CP_CODE                = "00000"

// MARK: File Manager
func getFileSize (filePath: String) -> UInt64 {
    if let filePathAttributes:NSDictionary? = try? NSFileManager.defaultManager().attributesOfItemAtPath(filePath) {
        return filePathAttributes!.fileSize();
    }

    return 0
}


func sendPictureToAkamaiNetStorageCDN(localImageFileLocation:String, onSuccessHandler:((fileUploadPath: String)->())? = nil, onErrorHandler:((NSError)->())? = nil) -> NSURLSessionDataTask? {

    let config = NSURLSessionConfiguration.defaultSessionConfiguration()
    let session: NSURLSession? = NSURLSession(configuration: config, delegate: nil, delegateQueue: NSOperationQueue.mainQueue())

    let request_time: NSTimeInterval = NSDate().timeIntervalSince1970
    let uniqueID:String = NSUUID().UUIDString.lowercaseString

    let auth_data:String = String(format: "5, 0.0.0.0, 0.0.0.0, %.0f, \(uniqueID), \(kAKAMAI_CONFIGURATION_NETSTORAGE_USER_NAME)", request_time)

    let uniqueFileName:String = "\(uniqueID).jpg"

    var akamaiNetStoragePartialPathURL:String = "/\(kAKAMAI_CONFIGURATION_NETSTORAGE_CP_CODE)/my_folder/%@"

    let fileUploadURLPath: String = String(format:"https://%@\(akamaiNetStoragePartialPathURL)", kAKAMAI_CONFIGURATION_NETSTORAGE_HOSTNAME, uniqueFileName)

    let action_data:String = String(format:"version=1&action=upload")

    let headerFileName:String = String(format:"\(akamaiNetStoragePartialPathURL)", uniqueFileName)

    let signature:String = String(format: "%@%@\nx-akamai-acs-action:%@\n", auth_data, headerFileName, action_data)

    // For HMAC-SHA1 see https://gist.github.com/aldo-jlaurenstin/96db6f5c0e651732c842
    let auth_sign = ALCommonHMAC.hmacSHA256(signature, withKey: kAKAMAI_CONFIGURATION_NETSTORAGE_KEY)

    let request = NSMutableURLRequest(URL: NSURL(string: fileUploadURLPath)!)
    request.HTTPMethod = "POST"

    request.setValue(action_data, forHTTPHeaderField: "X-Akamai-ACS-Action")
    request.setValue(auth_data, forHTTPHeaderField: "X-Akamai-ACS-Auth-Data")
    request.setValue(auth_sign, forHTTPHeaderField: "X-Akamai-ACS-Auth-Sign")
    request.setValue("image/jpeg", forHTTPHeaderField: "Content-Type")
    request.setValue(String(format:"%i", self.getFileSize (localImageFileLocation)), forHTTPHeaderField: "Content-Length")
    request.HTTPShouldHandleCookies = false

    let url: NSURL = NSURL(fileURLWithPath: localImageFileLocation)
    let task = session!.uploadTaskWithRequest(request, fromFile: url, completionHandler: {(data: NSData?, response: NSURLResponse?, error: NSError?) in
        if data == nil {
            // Handle error
        }
        else {
            if let httpResponse = response as? NSHTTPURLResponse {
                if httpResponse.statusCode == 200 {
                    // Upload successful
                    return
                }
            }

            // If not code 200, there was an error
        }
    })

    task.priority = NSURLSessionTaskPriorityHigh
    task.resume()
    return task
}

您可能需要更改一些内容（主要是您的上传路径），但此解决方案适用于我。

此致

将文件上传到IOS中的NetStorage / Akamai（Swift）
