我想使用angular $ http方法将一个文件上传到节点后端
我想上传包含其他表单字段的表单。
这是我的代码
var data = new FormData();
data.append('title', 'sometitle');
data.append('uploadedFile', $scope.uploadedFile);
FileService.upload(url, data, function(data, status) {
if(status===HTTP_OK) {
$scope.uploadSuccess = true;
$scope.showUploadProgressBar = false;
} else {
// error occured
console.log(data);
}
});
的FileService
FileService.upload = function(url, data, callback) {
$http({
method : 'POST',
url : url,
data : data,
headers: {'Content-Type': undefined },
transformRequest: angular.identity
}).success(function(data, status) {
callback(data, callback);
}).error(function(data, status) {
callback(data, status);
});
};
我正在使用节点多方模块进行文件上传。我正确地收到了文件。但是标题的字段值是未定义的。
我不知道为什么标题值未定义
Node.js后端文件上传处理程序
var form;
if(options.uploads.tempDir) {
form = new multiparty.Form({uploadDir : options.root + '/' + options.uploads.tempDir});
} else {
form = new multiparty.Form();
}
form.on('file', function(name, receivedFile) {
var tmpPath = receivedFile.path,
fileName = receivedFile.originalFilename,
targetDirectory = uploadDirectory + '/' + req.params.id,
targetPath = targetDirectory + '/' + fileName,
file = {
filePath : targetPath,
tempPath : tmpPath,
fileName : fileName,
size : receivedFile.size
};
fileUploadStatus.file = file;
// move file
fse.move(tmpPath, targetPath, function(err) {
if(err) {
console.log('Error moving file [ ' + targetPath + ' ] ' + JSON.stringify(err));
}
});
});
form.on('error', function(err) {
fileUploadStatus.err = err;
req.fileUploadStatus = fileUploadStatus;
next();
});
form.on('close', function() {
req.fileUploadStatus = fileUploadStatus;
next();
});
form.on('field', function(name, value) {
console.log('field called');
console.log(name);
console.log(value);
req.body = req.body || {};
req.body[name] = value;
});
// ignoring parts. Implement any other logic here
form.on('part', function(part) {
var out = new stream.Writable();
out._write = function (chunk, encoding, done) {
done(); // Don't do anything with the data
};
part.pipe(out);
});
// parsing form
form.parse(req);
