节点 JS:文件上传错误 [ERR_STREAM_WRITE_AFTER_END]

Node JS: File upload Error [ERR_STREAM_WRITE_AFTER_END]

所以我想做的是,我只是在 Formidable 模块的帮助下使用 nodeJS 将文件上传到特定文件夹,使用以下参考。 File Upload using nodeJS

现在,我的文件已上传到我想要的文件夹,但由于我是 运行 来自 CLI 的命令,它给我一个错误

这是我试过的 代码 :

var http = require('http') ;
var formidable = require('formidable') ;
var fs = require('fs');


http.createServer(function(req, res){
if(req.url == '/fileUpload'){
    var form = new formidable.IncomingForm();
    form.parse(req, function(err,fields,files){
        var oldpath = files.filetoupload.path;
        var newpath = 'C://xampp/htdocs/nodejs/upload/' + files.filetoupload.name;
        fs.rename(oldpath, newpath, function (err){
            if(err) throw err;
            res.write('File Uploaded and Moved !!');
            res.end();
        });
        res.write('File Uploaded');
        res.end();
    });
}
else{
    res.writeHead(200, {'Content-Type': 'text/html'}) ;
    res.write('<form action="fileUpload" method = "post" enctype="multipart/form-data">');
    res.write('<input type = "file" name="filetoupload" /><br/>') ;
    res.write('<input type="submit" />') ;
    res.write('</form>') ;
    return res.end() ;
    }
}).listen(8080) ;

我得到的错误是:

> Error [ERR_STREAM_WRITE_AFTER_END]: write after end
>     at write_ (_http_outgoing.js:572:17)
>     at ServerResponse.write (_http_outgoing.js:567:10)

您正在关闭流后尝试写入。


    var form = new formidable.IncomingForm();
    form.parse(req, function(err,fields,files){
        var oldpath = files.filetoupload.path;
        var newpath = 'C://xampp/htdocs/nodejs/upload/' + files.filetoupload.name;
        fs.rename(oldpath, newpath, function (err){
            if(err) throw err;
            res.write('File Uploaded and Moved !!');
            res.end(); // here, remove this end call
        });
    });
