Question

I'm using an easy library called HappyHTTP in my C++ project (link to the lib : https://github.com/Zintinio/HappyHTTP)

I want to send a file to my nodejs server.

my javascript code is as follows :

    var multer  = require('multer');
    var upload = multer({ dest: 'uploads/' });
    router.post('/dicomPost',upload.single('dicom'),function (req,res) {


    res.send(200);

})

and this is my C++ code :

             happyhttp::Connection conn( "127.0.0.1", 3000 );
             conn.setcallbacks( OnBegin, OnData, OnComplete, 0 );
             conn.putrequest( "POST", "/dicomPost" );
             conn.putheader( "Connection", "close" );
             conn.putheader( "Content-Length", l);
             conn.putheader( "Content-type", "multipart/form-data" );
             conn.putheader("Content-Disposition","name=dicom; filename=test.txt");
             conn.putheader( "Accept", "text/plain" );
             conn.endheaders();

             while( conn.outstanding() )
                 conn.pump();

from my C++ side, I can send body data but when it comes to a file , I'm getting a 500 Internal Server Error),please can anyone has a look at the github link above and see why my code is not working. I don't want to use libcurl because it's large, I just want to make a post with a lightwheight library as HappyHttp.

thank you in advance.

问题出在服务器端，因此请检查服务器日志以查看是否有任何线索。我的猜测是uploads文件夹上的权限问题阻止你的javascript在那里写任何文件。
