我正在尝试在Swift中上传带参数的图像.当我尝试这段代码时,我可以得到参数而不是图像

uploadFileToUrl(fotiño:UIImage){
    var foto =  UIImage(data: UIImageJPEGRepresentation(fotiño, 0.2))


    var request = NSMutableURLRequest(URL:NSURL(string: "URL"))
    request.HTTPMethod = "POST"

    var bodyData = "id_user="PARAMETERS&ETC""


    request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding);
    request.HTTPBody = NSData.dataWithData(UIImagePNGRepresentation(foto))
    println("miraqui \(request.debugDescription)")
    var response: AutoreleasingUnsafeMutablePointer<NSURLResponse?>=nil
    var HTTPError: NSError? = nil
    var JSONError: NSError? = nil

    var dataVal: NSData? =  NSURLConnection.sendSynchronousRequest(request, returningResponse: response, error: &HTTPError)

    if ((dataVal != nil) && (HTTPError == nil)) {
        var jsonResult = NSJSONSerialization.JSONObjectWithData(dataVal!, options: NSJSONReadingOptions.MutableContainers, error: &JSONError)

        if (JSONError != nil) {
            println("Bad JSON")
        } else {
            println("Synchronous\(jsonResult)")
        }
    } …

所以这个HTML代码为我提交了正确格式的数据.

<form action="https://www.example.com/register.php" method="post" enctype="multipart/form-data">
    Name: <input type="text" name="userName"><BR />
    Email: <input type="text" name="userEmail"><BR />
    Password: <input type="text" name="userPassword"><BR />
    Avatar: <input type="file" name="avatar"><BR />
    <input type="submit">
</form>

我已经查看过很多关于如何在iOS上进行multipart/form-data POST的文章,但没有一篇真正解释如果有正常的参数以及文件上传怎么办.

你能帮我解决一下在Obj-C中发帖的代码吗？

谢谢!
