重命名multer中上传的文件

Question

Here I'm trying to rename both the files as file1 and file2 , but both the files are renamed as file2 .

HTML

<input type="file" name="file1" file-model = "file1"/>
<input type="file" name="file2" file-model = "file2"/>
<button ng-click = "uploadFile()">UPLOAD FILES</button>

Server

app.use(multer({
    dest: 'uploads/',
    rename: function(file2, file2) {
        return "file1"
    },
    rename: function(file2, file2) {
        return "file2"
    }

}));

when i'm returning return file1+"file1" and return file2+"file2" the files are renamed as originalnamefile1 and originalnamefile2 . tried a few things but unable to get it right . My nulter version is 0.1.6

Having multiple rename func doesn't make any sense, last will always override previous ones. Take a look at sample below

app.use(multer({
    dest: 'uploads/',
    rename: function(fieldname, filename) {
        //check fieldname
        if(fieldname === 'file1') {
            //be aware, no file extension added here
            //if you want to add ext - use
            //return 'file1.' + filename.split('.').pop();
            return 'file1';
        } else if (fieldname === 'file2') {
            return 'file2';
        //do something when fieldname is different
        } else {
            //generate some id
            return Math.round(Math.random() * 1000);
        }
    }
}));
