我正在尝试使用 busboy-connect 来解析我发送到服务器的请求文件。当我打印出我的请求对象时，我得到了这个巨大的 Angular.identity 对象，当我尝试使用以下代码解析对象时：

app.post("/compositions/fileUpload", function(req, res){
var fstream;

     req.pipe(req.busboy);

     req.busboy.on('file', function (fieldname, file, filename) {

        console.log("Uploading: " + filename); 

        fstream = fs.createWriteStream('/files/' + filename);

        file.pipe(fstream);

        fstream.on('close', function () {

            res.redirect('back');

        });
    });

我在“req.pipe(req.busboy)”上出错了。我确实需要 connect-busboy 和 fs。我还确保告诉我的应用程序使用 busboy，所以他们应该在那里。但是，我继续收到此错误：

我不知道为什么。似乎这里还有另一个类似的问题，但尚未解决。有谁知道这个错误可能是由什么引起的？谢谢！

问题是我在全局范围内的模块上方不需要（connect-busboy）。
