我在使用nodeJS和Angular上传文件时遇到了问题。
我找到了一些解决方案,但都是使用Ajax的,而我对此不太了解。是否有可能不使用Ajax来完成上传?
使用以下代码时,我遇到了这个错误:
POST http://localhost:2000/database/sounds 413 (Payload Too Large)
代码:
HTML:
<div class="form-group">
<label for="upload-input">This needs to be a .WAV file</label>
<form enctype="multipart/form-data" action="/database/sounds" method="post">
<input type="file" class="form-control" name="uploads[]" id="upload-input" multiple="multiple">
</form>
<button class="btn-primary" ng-click="uploadSound()">UPLOAD</button>
</div>
Javascript:
$scope.uploadSound = function(){
var x = document.getElementById("upload-input");
if ('files' in x) {
if (x.files.length == 0) {
console.log("Select one or more files.");
} else {
var formData = new FormData();
for (var i = 0; i < x.files.length; i++) {
var file = x.files[i];
if(file.type==("audio/wav")){
console.log("Importing :");
if ('name' in file) {
console.log("-name: " + file.name);
}
if ('size' in file) {
console.log("-size: " + file.size + " bytes");
}
formData.append('uploads[]', file, file.name);
}else{
console.log("Error with: '"+file.name+"': the type '"+file.type+"' is not supported.");
}
}
$http.post('/database/sounds', formData).then(function(response){
console.log("Upload :");
console.log(response.data);
});
}
}
}
NodeJS:
//Upload a sound
app.post('/database/sounds', function(req, res){
var form = new formidable.IncomingForm();
// specify that we want to allow the user to upload multiple files in a single request
form.multiples = true;
// store all uploads in the /uploads directory
form.uploadDir = path.join(__dirname, '/database/sounds');
// every time a file has been uploaded successfully,
// rename it to it's orignal name
form.on('file', function(field, file) {
fs.rename(file.path, path.join(form.uploadDir, file.name));
});
// log any errors that occur
form.on('error', function(err) {
console.log('An error has occured: \n' + err);
});
// once all the files have been uploaded, send a response to the client
form.on('end', function() {
res.end('success');
});
// parse the incoming request containing the form data
form.parse(req);
});
编辑:
错误变成了
POST http://localhost:2000/database/sounds 400 (Bad Request)
`POST http://localhost:2000/database/sounds 400 (Bad Request)`
