我正在使用以下代码将单个图像上传到服务器:

private static func urlRequestWithComponents(urlString:String, parameters:Dictionary<String, String>, imageData:NSData?, imageName: String) -> (URLRequestConvertible , NSData) {

        // add image
        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Disposition: form-data; name=\"\(imageName)\"; filename=\"\(StringHelper.sharedInstance.randomString(5)).png\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData(imageData!)
    }
    // add parameters
    for (key, value) in parameters { …
