Question

我在做什么 ::

我正在尝试从客户端发布图像，我想在控制台中打印文件的名称
此图片属于multipart

什么无效 ::

my express未处理服务器上的multipart数据

app.js

var http=require('http');
var crypto=require('crypto');

var app=express();


app.set('port',process.env.PORT||7002); 

app.use('/Details',express.static(__dirname+'/public/images'));

//.use(express.cookieParser());

app.use(express.bodyParser());

app.post('/Details/',function(req,res,next){



        var file_name=req.files.key.originalFilename;
        console.log(file_name);


});

app.get('/Details/',function(req,res){
        res.send("Image displayed");
});

http.createServer(app).listen(app.get('port'),function(){
        console.log('Express server listening on port'+app.get('port'));

});

我的控制台出错 ::

我该如何调试

Answer 1

您是否使用enctype="multipart/form-data"设置了表单的属性？

表格应为

<form method="post" enctype="multipart/form-data">
...
</form>

Expressjs不处理多部分数据
