Question

I am trying to post an image to facebook using scribe library. My code is:

String apiKey = "MY_API_KEY";
        String apiSecret = "MY_SECRET_KEY";
        OAuthService service = new ServiceBuilder().provider(FacebookApi.class).apiKey(apiKey)
                .apiSecret(apiSecret)
                .callback("MY_CALL_BACK_URL")
                .build();

        Token accessToken = new Token("MY_ACCESS_TOKEN","");
        OAuthRequest request = new OAuthRequest(Verb.POST, PROTECTED_RESOURCE_URL_STREAM);       
        request.addHeader("Content-Type", "text/html");      
        request.addBodyParameter("message", "Testing auto update.. Please ignore " + new DateTime());           
        //MultiPart for pic
        Multipart mp = new MimeMultipart();
        MimeBodyPart htmlPart = new MimeBodyPart();
        ByteArrayOutputStream out = new ByteArrayOutputStream();    
        try {
            byte[] imagePayLoad = msgBody.getBytes("UTF-8");    //msgBody contains html string   
            byte[] mpByte = new byte[imagePayLoad.length];
            htmlPart.setContent(msgBody, "text/html");
            mp.addBodyPart(htmlPart);           
            //here I get the bytes[] of mp to out
            mp.writeTo(out);
            out.write(mpByte);      

            request.addPayload(mpByte);
        } catch (Exception e) {         
            e.printStackTrace();
        }   
        service.signRequest(accessToken, request);
        Response response = request.send();
        System.out.println("Response");
        System.out.println();    
        System.out.println(response.getCode());
        System.out.println(response.getBody());

    }

但我也得到

400
{"error":{"message":"(#100) Missing message or attachment","type":"OAuthException","code":100}}

任何人都能帮忙吗? 如果我拿出多部分, “测试自动更新。请更新 i ” 的文本将更新到 Facebook 。我需要上传图片和字节。

谢谢谢谢

我用的是:

 <dependency>
<groupId>org.scribe</groupId>
<artifactId>scribe</artifactId>
<version>1.3.0</version>
</dependency>

Scribe使用addBodyParater 或addPayload ,不是两者都使用。见这一方法。

如果您选择了 addPayload 方式, 那么我想您将不得不找出如何将 < code> message 也引入多部分。

注:请求中实际内容的字符串输出(使用 Request#getBodyContents )将很好。
