使用PlayFramework的多个上传文件 [英] Multiple upload file with PlayFramework

问题描述

我试图用Play Framework一次上传多个文件，但是我总是得到每个上传的第一张图片。这里有一个具体的例子：

HTML：

 < form method =postaction =/ uploadenctype =multipart / form-data> 
< input type =filename =image/> 
< input type =filename =image/> 
< input type =filename =image/> 
< input type =filename =image/> 
 
< input type =submitname =submitvalue =Send images/> 
< / form> 
  

控制器：

  public static void upload（）{
 File [] images = params.get（image，File []。class）; 
（文件f：图像）{
 Logger.info（f.getName（））; 
 
 
 code 
 $ b如果我上传image1.jpg，image2.jpg， image3.jpg& image4.jpg，控制台上的 Logger.info 会显示： 
 
 
  image1.jpg 
 image1.jpg 
 image1.jpg 
 image1.jpg 
  
其他图片将不会被使用。
 
 
 
我尝试使用 List< File>   File [] 但是也不行。 
 
 
我也看到这里有同样的问题所以（这里），这使用这个答案：
 列表<上传> files =（List< Upload>）request.args.get（__ UPLOADS）; 
  
但在Play！v1.2.4中不起作用。
 
 
 
我正在使用Play v1.2.4。
 
 
 
非常感谢您的帮助！
 <我已经打开了一个
 

在Play上只显示第一个文件＃ticket-1391-1rel =nofollow> ticket ！框架，因为它似乎是问题，显然，我不是唯一一个有这种行为。

我测试了新的1.2.5，并且问题是固定的，至少用我给出的解决方案：

  public static void upload（）{
 File [] images = params.get（image，File []。class）; 
（文件f：图像）{
 Logger.info（f.getName（））; 
 
 
 $ / code $ / $ p

I'm trying to upload multiple files at once with Play Framework, but I always get the first image for each uploaded. Here's a concrete case :

The HTML :
<form method="post" action="/upload" enctype="multipart/form-data">
    <input type="file" name="image" />
    <input type="file" name="image" />
    <input type="file" name="image" />
    <input type="file" name="image" />

    <input type="submit" name="submit" value="Send images" />
</form>
The controller :
public static void upload() {
    File[] images = params.get("image", File[].class);
    for (File f : images) {
        Logger.info (f.getName());
    }
}
If I upload image1.jpg, image2.jpg, image3.jpg & image4.jpg, the Logger.info on the console will display :
image1.jpg
image1.jpg
image1.jpg
image1.jpg
The other images won't be used.

I tried with List<File> instead of File[] but it doesn't work neither.

I also saw there is kind the same question here on SO (here), that use this as an answer :
List<Upload> files = (List<Upload>) request.args.get("__UPLOADS");
But it doesn't work in the v1.2.4 of Play!.

I'm using Play v1.2.4.

Thank you really much for your help!
解决方案
Well, I have opened a ticket at Play! Framework because it seems to be problem, and apparently, I'm not the only one to have this behavior.

I tested with the new 1.2.5, and the problem is fixed, at least with the solution I gave on the question :
public static void upload() {
    File[] images = params.get("image", File[].class);
    for (File f : images) {
        Logger.info (f.getName());
    }
}
Note: I'm using Java 7!
