Swift上传文件到PHP服务器

Question

所以我将一个文件从swift上传到PHP服务器，POST请求按预期到达头文件，但我无法从$_FILES获取任何内容。 它只是一个空数组。

我在Swift方面显然做错了，这是我的代码：

func testUpload(){
    let bundle = NSBundle.mainBundle()
    let path = bundle.pathForResource("someTestFile", ofType: "zip")!
    var data: NSData = NSData(contentsOfFile: path)!

    var request = NSMutableURLRequest(URL: NSURL(string: "http://testsite.com/upload")!)
    request.HTTPMethod = "POST"

    let boundary = "----------ds2Gry67efddagdfsfhsHF"
    let contentType = "multipart/form-data; boundary=\(boundary)"
    request.setValue(contentType, forHTTPHeaderField:"Content-Type")
    request.setValue("Keep-Alive", forHTTPHeaderField: "Connection")
    self.uploadFiles(request, data: data)
}

func uploadFiles(request: NSURLRequest, data: NSData) {
    var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    var session = NSURLSession(configuration: configuration, delegate: self, delegateQueue: NSOperationQueue.mainQueue())
    var task = session.uploadTaskWithRequest(request, fromData: data)
    task.resume()
}

我很确定我错过了一些东西，我只是想不通它是什么......
