Question

I have a Java application and i try to upload a photo to Facebook via graph api with Jersey. Until now everything works fine with Jersey I can publish messages etc.

I searched hours to find an example how to do it. The best tutorial I found was this one:

http://neopatel.blogspot.de/2011/04/jersey-posting-multiple-data.html" rel="no follow" >http://neopatel.blogspot.de/2011/04/jersey-posting-multipart-data.html

我只知道我要使用多部分/格式数据。

是否有人有例子或知道必须这样做?

Answer 1

您是否尝试使用"http://jersey.java.net/nonav/apidocs/1.8/contribs/jersey-mulpart/index.html" rel=“nofollow”>jersey-mulpart 套件?

您为文件创建了 < code> FormDataMultiPart ,为信件创建了 < code> FileDataBodyPart ,为信件创建了 < code> FormDataBodyPart ,为信件创建了 < fileDataBodyPart ,为信件创建了 < folleDataBodyPart > 和访问用户创建了 < formDataBodyPart 。

Answer 2

这是我的解决方案

String url = "https://graph.facebook.com/me/photos";
File file = new File("path");

ClientConfig cc = new DefaultClientConfig();
cc.getClasses().add(MultiPartWriter.class);
Client client = Client.create(cc);

WebResource webResource = client.resource(url); 
FormDataMultiPart fdmp = new FormDataMultiPart(); 

fdmp.bodyPart(new FileDataBodyPart("source", file, MediaType.APPLICATION_OCTET_STREAM_TYPE));
fdmp.bodyPart(new FormDataBodyPart("message", "YAY I did it!"));
fdmp.bodyPart(new FormDataBodyPart("access_token", accessToken));

ClientResponse response = webResource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(ClientResponse.class, fdmp); 
String string = response.getEntity(String.class);
