播放框架在HTTP请求中发送文件

Question

I'm working on a play framework 2 application and I would like to call a WebService and send a file ( an image ). I found the WS class but I cannot find how to send a file using it. What I found is this :

WS.url("http://localhost:9001/post").post("content")

But I did not managed to send a file using a POST request.

Can someone tell me how to do it ?

Thanks.

Answer 1

With Play > 2.0 this should do the trick:

File file = new File("yourPath");
WS.url("/post/url").post(file);

Being able to add a parameter identifying your file the request should be send using multipart/form-data. This Post shows how to do it with Play! - https://stackoverflow.com/a/18723326/2788883
