Swift上传文件到PHP服务器

Question

所以我将文件从swift上传到PHP服务器,POST请求按预期到达标题,所有但我无法得到任何东西$_FILES.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......

POST 方法，需要添加 header application/x-www-form-urlencoded
