Box.net api从Salesforce上传文件

Question

我使用以下代码使用V2 api从Salesforce将文件上传到Box.net并出现以下错误

System.HttpResponse [状态=未找到，StatusCode = 404]

String sUrl = 'https://upload.box.com/api/2.0/files/data' ;
Http h = new Http();
HttpRequest req = new HttpRequest();
req.setEndpoint(sUrl);
req.setHeader('Authorization', newAuthorization);      
req.setMethod('POST');

req.setHeader('Content-Type', 'application/pdf');
String content = '{"filename":"/Users/rmasineni/temp/DealPackage/Cederquist Credit Memo.pdf", "folder_id":"0"}';

//String content = '{"filename":"&", "folder_id":"0"}';
req.setbody(content);

HttpResponse res;
res = h.send(req);

如果有人帮助我如何使用Box-api V2上传文件，那将会很棒。

谢谢， 抹布
